新项目的辅助系统，需要用到mongo系统，今天再次将其使用环境进行了操作搭建。还是遇到一些问题，毕竟之前使用的场景和现在的不同。版本也不一样了。
本次使用的环境：
mongo：3.4.4版本
OS： redhat7
java操作mongo库
1. 首先，mongo数据库的安装
直接到mongodb官网下载mongodb-linux-x86_64-rhel70-3.4.4.tgz。解压之后，运行mongod即可启动服务。当然，我这里是为了项目开发用，第一步就启用单实例。
看看我们的mongodb的配置：
#数据库数据存放路径dbpath = /home/tkrobot/mongodb/data#日志存放路径
logpath = /home/tkrobot/mongodb/logs/mongodb.log
logappend = true
port = <span style="color: #017
fork = true#启动认证功能，要想连接到数据库，必须经过用户名密码认证才可以
auth = true#禁止http访问数据库
nohttpinterface = true#连接数据库时必须是这个ip
bind_ip = <span style="color: #.90.<span style="color: #.10
journal = true#最大连接数
maxConns = <span style="color: #0
这里，需要在mongod启动前，创建好/home/tkrobot/mongodb/data以及/home/tkrobot/mongodb/logs两个目录。
启动mongod的脚本：
./mongod --config /etc/mongodb.conf
这样，mongod就算启动好了。下面有其启动日志：

2. 接下来，我们操作一下，验证数据库部署的情况是否ok。
为了方便使用mongo客户端指令，将解压后的mongo配置到环境变量里面，方便操作。
export MONGODB_PATH=/home/tkrobot/mongodb-linux-x86_64-rhel70-3.4.4
export PATH=$JAVA_HOME/bin:$MONGODB_PATH/bin:$PATH
用mongo登录操作数据库：
[root@localhost bin]# mongo
MongoDB shell version v3.<span style="color: #.4
connecting to: mongodb://<span style="color: #.90.7.10:27017
MongoDB server version: <span style="color: #.4.<span style="color: #

没有权限，因为我们在mongod.conf里面指定要auth了。最简单的办法，就是将mongod.conf里面的auth注释掉，重新启动mongod，进行权限配置。
在没有auth属性的情况下，启动mongod，然后再次mongo连接上数据库，use指定的数据库，创建一个专属的用户。
use robotkdb
指定数据库robotkdb后，创建一个用户robotassister。
db.createUser({
... user:"robotassister",
... pwd:"xxyyyxxxxx",
... roles:[{role:"dbOwner",db:"robotkdb“}]})
这样，就相当于给指定的数据库robotkdb创建了一个角色为dbOwener的用户robotassister。
最后，将mongodb.conf中的auth重新放开，启用auth，再启动mongod，并进行指定数据库和用户名的方式连接到mongodb：
mongo --host <span style="color: #.90.<span style="color: #.10 --port <span style="color: #017 -u robotassister -p xxyyyxxxx robotdb
如此，一切都ok，单实例的mongod配置带auth的启动，客户端通过credentials的方式连接到指定的库，准备工作就绪。
3. spring集成mongodb。
安装spring官方的文档介绍，这个过程是比较简单的。集成过程中需要用到的支持mongodb的jar包也不多。主要有：
mongo-java-driver-<span style="color: #.4.<span style="color: #.jar
spring-data-commons-<span style="color: #.10.<span style="color: #.RELEASE.jar
spring-data-commons-core-<span style="color: #.4.<span style="color: #.RELEASE.jar
spring-data-mongodb-<span style="color: #.7.<span style="color: #.RELEASE.jar
上述的jar是我的集成过程中用到的。
我在自己既有的spring mvc的web项目里面，添加了mongodb的支持。
首先看看mongodb的xml配置文件spring-mongo.xml：
&?xml version="<span style="color: #.0" encoding="UTF-8"?&
&beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.2.xsd"
default-lazy-init="default"&
&!--credentials的配置形式是：用户名:密码@默认数据库--&
&mongo:mongo-client id="mongoClient" host="${mongo.host}" port="${mongo.port}"
credentials="${mongo.username}:${mongo.password}@${mongo.dbname}"&
&mongo:client-options
write-concern="SAFE"
connections-per-host="${mongo.connectionsPerHost}"
threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"
connect-timeout="${mongo.connectTimeout}"
max-wait-time="${mongo.maxWaitTime}"
socket-timeout="${mongo.socketTimeout}"/&
&/mongo:mongo-client&
&mongo:db-factory id="mongoDbFactory" dbname="${mongo.dbname}" mongo-ref="mongoClient" /&
&bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"&
&constructor-arg name="mongoDbFactory" ref="mongoDbFactory" /&
其中的参数配置文件mongo.properties:
mongo.dbname=robotkdb
mongo.host=<span style="color: #.90.<span style="color: #.10
mongo.port=<span style="color: #017
mongo.username=robotassister
mongo.password=xxyyyxxxxx
#一个线程变为可用的最大阻塞数
mongo.connectionsPerHost=<span style="color: #
#线程队列数,它以上面connectionsPerHost值相乘的结果就是线程队列最大值
mongo.threadsAllowedToBlockForConnectionMultiplier=<span style="color: #
#连接超时时间（毫秒）
mongo.connectTimeout=<span style="color: #00
#最大等待时间
mongo.maxWaitTime=<span style="color: #00
mongo.autoConnectRetry=true
#scoket保持活动
mongo.socketKeepAlive= true
#scoket超时时间
mongo.socketTimeout=<span style="color: #00
mongo.slaveOk=true
接下来，看看spring的配置文件applicationContext.xml:
&?xml version="<span style="color: #.0" encoding="UTF-8"?&
&beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:cache="http://www.springframework.org/schema/cache"
xsi:schemaLocation="

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.2.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"&
&bean id="configRealm" class="org.springframework.beans.factory.config.PropertiesFactoryBean"&
&property name="locations"&
&value&classpath:conf/internal.properties&/value&
&value&classpath:conf/jdbc.properties&/value&
&value&classpath:conf/redis.properties&/value&
&value&classpath:conf/session.properties&/value&
&value&classpath:conf/mongo.properties&/value&
&/property&
&bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer"&
&property name="properties" ref="configRealm"/&
&bean id="springCacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"&
&property name="cacheManager" ref="ehcacheManager"/&
&bean id="ehcacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"&
&property name="configLocation" value="classpath:conf/ehcache.xml"/&
&cache:annotation-driven cache-manager="springCacheManager"/&
&import resource="spring-servlet.xml"/&
&import resource="spring-cache.xml"/&
&import resource="spring-dao.xml"/&
&import resource="spring-redis.xml"/&
&import resource="spring-mongo.xml"/&
ok,到此，所有的配置工作都完毕了，我们就启动web项目，看看是否能正常启动吧！遗憾，出了下面的错误！！！！！

这个，还真是折腾了我一段时间，最终找到原因：
上述这个错误，需要在spring-mongo.xml文件中添加下面的两行内容
http://www.springframework.org/schema/data/repository
http://www.springframework.org/schema/data/repository/spring-repository-1.7.xsd
采用基于mongo:mongo-client标签进行安全配置，mongo要求spring-mongo.xsd必须是1.6及以上的版本。我们这里选用的是1.7.
ok，再次运行看看吧。。。。。。结果如何呢。。。。。。。。。

又出现了错误。。。看来不是很顺利啊，再研究看root cause是什么呢？？？依据
爆出上述错误，经过查找原因，得知，sping-data-mongo要求spring-core必须是4.x的版本，也就是说spring4才行。
源头是通过查找日志中红色部分的错误信息，得知相关的jar依赖文件，在spring-core 4.x的版本中默认含有，于是，将项目中原来3.2的配置信息，全部更新为4.2的，并相应的将工程的lib中spring的版本更新到4.2.再次启动应用。这次，一切都ok了。
最终能正常运行的applicationContext.xml的内容如下：

4. 启用一个测试，验证一下spring和mongodb的集成是否成功吧
先构建一个javabean：
* @author "shihuc"
package com.roomdis.center.mongo.
import java.io.S
import org.ietf.jgss.O
import org.springframework.data.mongodb.core.mapping.D
import org.springframework.data.mongodb.core.mapping.F
* @author chengsh05
@Document(collection="buzz_element")
public class BuzzElement implements Serializable {
private static final long serialVersionUID = <span style="color: #L;
private Oid _
@Field(value="item_id")
private String itemId;
@Field(value="item_name")
private String itemN
@Field(value="price")
@Field(value="desc")
public Oid get_id() {
public void set_id(Oid _id) {
this._id = _
public String getItemId() {
return itemId;
public void setItemId(String itemId) {
this.itemId = itemId;
public String getItemName() {
return itemN
public void setItemName(String itemName) {
this.itemName = itemN
public String getPrice() {
public void setPrice(String price) {
this.price =
public String getDesc() {
public void setDesc(String desc) {
this.desc =
public String toString() {
return "ItemInfo [_id=" + _id + ", itemId=" + itemId + ", itemName="
+ itemName + ", price=" + price + ", desc=" + desc + "]";
再创建工具类BeanUtil：
* @author "shihuc"
package com.roomdis.center.mongo.
import java.lang.reflect.F
import java.lang.reflect.InvocationTargetE
import java.util.D
import mons.beanutils.BeanU
import com.mongodb.BasicDBO
import com.mongodb.DBO
* @author chengsh05
public class BeanUtil {
* 把实体bean对象转换成DBObject
* @param bean
* @throws IllegalArgumentException
* @throws IllegalAccessException
public static &T& DBObject bean2DBObject(T bean) throws IllegalArgumentException,
IllegalAccessException {
if (bean == null) {
return null;
DBObject dbObject = new BasicDBObject();
// 获取对象对应类中的所有属性域
Field[] fields = bean.getClass().getDeclaredFields();
// 获取所有注解
for (Field field : fields) {
org.springframework.data.mongodb.core.mapping.Field anno = field.getAnnotation(org.springframework.data.mongodb.core.mapping.Field.class);
// 获取属性名
String varName = field.getName();
if("serialVersionUID".equals(varName) || "_id".equals(varName)){
// 获取注解的值
varName = anno.value();
// 修改访问控制权限
boolean accessFlag = field.isAccessible();
if (!accessFlag) {
field.setAccessible(true);
Object param = field.get(bean);
if (param == null) {
} else if (param instanceof Integer) {//判断变量的类型
int value = ((Integer) param).intValue();
dbObject.put(varName, value);
} else if (param instanceof String) {
String value = (String)
dbObject.put(varName, value);
} else if (param instanceof Double) {
double value = ((Double) param).doubleValue();
dbObject.put(varName, value);
} else if (param instanceof Float) {
float value = ((Float) param).floatValue();
dbObject.put(varName, value);
} else if (param instanceof Long) {
long value = ((Long) param).longValue();
dbObject.put(varName, value);
} else if (param instanceof Boolean) {
boolean value = ((Boolean) param).booleanValue();
dbObject.put(varName, value);
} else if (param instanceof Date) {
Date value = (Date)
dbObject.put(varName, value);
// 恢复访问控制权限
field.setAccessible(accessFlag);
return dbO
* 把DBObject转换成bean对象
* @param dbObject
* @param bean
* @throws IllegalAccessException
* @throws InvocationTargetException
* @throws NoSuchMethodException
public static &T& T dbObject2Bean(DBObject dbObject, T bean) throws IllegalAccessException,
InvocationTargetException, NoSuchMethodException {
if (bean == null) {
return null;
Field[] fields = bean.getClass().getDeclaredFields();
for (Field field : fields) {
String varName = field.getName();
org.springframework.data.mongodb.core.mapping.Field anno = field.getAnnotation(org.springframework.data.mongodb.core.mapping.Field.class);
if("serialVersionUID".equals(varName) || "_id".equals(varName)){
String fieldName = anno.value();
Object object = dbObject.get(fieldName);
if (object != null) {
BeanUtils.setProperty(bean, varName, object);
再次，创建服务，进行操作数据库，相当于dao层：

import java.util.L
import org.json.JSONO
import com.roomdis.center.mongo.model.BuzzE

import com.roomdis.center.mongo.util.BeanU
* @author chengsh05
@Service("buzzElementService")
public class BuzzElementServiceImpl implements IBuzzElementService {
@Autowired
private MongoTemplate mongoT
private final static String COLLECTION_NAME = "buzz_element";
/* (non-Javadoc)
* @see com.roomdis.center.mongo.service.IBuzzElementService#getItemInfo(org.json.JSONObject)
public List&BuzzElement& getItemInfo(JSONObject json) throws Exception {
List&BuzzElement& list = new ArrayList&BuzzElement&();
// 判断查询的json中传递过来的参数
DBObject query = new BasicDBObject();
if(json.has("item_id")){
query.put("item_id", json.getString("item_id"));
}else if(json.has("item_name")){
query.put("item_name", json.getString("item_name"));
DBCursor results = mongoTemplate.getCollection(COLLECTION_NAME).find(query);
if(null != results){
Iterator&DBObject& iterator = results.iterator();
while(iterator.hasNext()){
BasicDBObject obj = (BasicDBObject) iterator.next();
BuzzElement itemInfo = new BuzzElement();
itemInfo = BeanUtil.dbObject2Bean(obj, itemInfo);
list.add(itemInfo);
/* (non-Javadoc)
* @see com.roomdis.center.mongo.service.IBuzzElementService#save(com.roomdis.center.mongo.model.BuzzElement)
public int save(BuzzElement itemInfo) throws Exception {
DBCollection collection = this.mongoTemplate.getCollection(COLLECTION_NAME);
int result = <span style="color: #;
DBObject iteminfoObj = BeanUtil.bean2DBObject(itemInfo);
//iteminfoObj.removeField("serialVersionUID");
//result = collection.insert(iteminfoObj).getN();
WriteResult writeResult = collection.save(iteminfoObj);
result = writeResult.getN();
/* (non-Javadoc)
* @see com.roomdis.center.mongo.service.IBuzzElementService#update(com.roomdis.center.mongo.model.BuzzElement)
public void update(BuzzElement intemInfo) throws Exception {
DBCollection collection = this.mongoTemplate.getCollection(COLLECTION_NAME);
BuzzElement queryItemInfo = new BuzzElement();
queryItemInfo.setItemId(intemInfo.getItemId());
DBObject itemInfoObj = BeanUtil.bean2DBObject(intemInfo);
DBObject query =
BeanUtil.bean2DBObject(queryItemInfo);
collection.update(query, itemInfoObj);
郑重说明，上述的javabean以及BeanUtil还有服务程序类，是参照网络资源，考虑到这些东西不是本博的重点，也不是关键，所以没有花时间在这个上面。
最后，我们写一个controller来模拟一下添加数据，查询数据以及更新数据，看看工作流程是否顺畅！

好了，代码都准备ok了，下面进行测试！
A.在浏览器地址栏执行：http://10.90.9.20:8080/RDcenter/mongo/save
数据库得到的数据：
& show collections
buzz_element
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a") }
B. 添加一条数据。在浏览器地址栏里面输入： http://10.90.9.20:8080/RDcenter/mongo/save?itemName=iphone7&price=7000&desc=good product, everyone loves it
数据库得到的数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a") }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
再次添加一条数据，在浏览器地址栏里面输入： http://10.90.9.20:8080/RDcenter/mongo/save?itemName=S8&price=8000&desc=samsung new product
数据库得到的数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a") }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
{ "_id" : ObjectId("<span style="color: #eb1bf8d04d70"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "samsung new product" }
C.查询数据，在浏览器地址栏输入：http://10.90.9.20:8080/RDcenter/mongo/find?itemName=S8
最终，浏览器上得到的返回结果是：
D. 更新数据，在浏览器地址栏输入：http://10.90.9.20:8080/RDcenter/mongo/update?itemName=S8&price=9000&desc=hope it is nice
更新前的数据库数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a"), "item_name" : "iphone7", "desc" : "not everyone will buy it" }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
{ "_id" : ObjectId("<span style="color: #eb1bf8d04d70"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "samsung new product" }
更新后的数据库数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "hope it is nice" }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
{ "_id" : ObjectId("<span style="color: #eb1bf8d04d70"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "samsung new product" }
从上面看，数据库是更新了，但是貌似有点逻辑问题，将第一个更新了，我们希望是将既有的item_name为S8产品数据更新的，这个是业务逻辑问题，暂且不做修改了。。。
从上面的全部过程来看，基于spring+mongodb的集成工作，完美结束，也很简单。
剩下来的，重点是mongodb的增删改查相关的接口研究，是个熟悉的过程，各位朋友，建议去看官网的资料。}

新项目的辅助系统，需要用到mongo系统，今天再次将其使用环境进行了操作搭建。还是遇到一些问题，毕竟之前使用的场景和现在的不同。版本也不一样了。
本次使用的环境：
mongo：3.4.4版本
OS： redhat7
java操作mongo库
1. 首先，mongo数据库的安装
直接到mongodb官网下载mongodb-linux-x86_64-rhel70-3.4.4.tgz。解压之后，运行mongod即可启动服务。当然，我这里是为了项目开发用，第一步就启用单实例。
看看我们的mongodb的配置：
#数据库数据存放路径dbpath = /home/tkrobot/mongodb/data#日志存放路径
logpath = /home/tkrobot/mongodb/logs/mongodb.log
logappend = true
port = <span style="color: #017
fork = true#启动认证功能，要想连接到数据库，必须经过用户名密码认证才可以
auth = true#禁止http访问数据库
nohttpinterface = true#连接数据库时必须是这个ip
bind_ip = <span style="color: #.90.<span style="color: #.10
journal = true#最大连接数
maxConns = <span style="color: #0
这里，需要在mongod启动前，创建好/home/tkrobot/mongodb/data以及/home/tkrobot/mongodb/logs两个目录。
启动mongod的脚本：
./mongod --config /etc/mongodb.conf
这样，mongod就算启动好了。下面有其启动日志：

2. 接下来，我们操作一下，验证数据库部署的情况是否ok。
为了方便使用mongo客户端指令，将解压后的mongo配置到环境变量里面，方便操作。
export MONGODB_PATH=/home/tkrobot/mongodb-linux-x86_64-rhel70-3.4.4
export PATH=$JAVA_HOME/bin:$MONGODB_PATH/bin:$PATH
用mongo登录操作数据库：
[root@localhost bin]# mongo
MongoDB shell version v3.<span style="color: #.4
connecting to: mongodb://<span style="color: #.90.7.10:27017
MongoDB server version: <span style="color: #.4.<span style="color: #

没有权限，因为我们在mongod.conf里面指定要auth了。最简单的办法，就是将mongod.conf里面的auth注释掉，重新启动mongod，进行权限配置。
在没有auth属性的情况下，启动mongod，然后再次mongo连接上数据库，use指定的数据库，创建一个专属的用户。
use robotkdb
指定数据库robotkdb后，创建一个用户robotassister。
db.createUser({
... user:"robotassister",
... pwd:"xxyyyxxxxx",
... roles:[{role:"dbOwner",db:"robotkdb“}]})
这样，就相当于给指定的数据库robotkdb创建了一个角色为dbOwener的用户robotassister。
最后，将mongodb.conf中的auth重新放开，启用auth，再启动mongod，并进行指定数据库和用户名的方式连接到mongodb：
mongo --host <span style="color: #.90.<span style="color: #.10 --port <span style="color: #017 -u robotassister -p xxyyyxxxx robotdb
如此，一切都ok，单实例的mongod配置带auth的启动，客户端通过credentials的方式连接到指定的库，准备工作就绪。
3. spring集成mongodb。
安装spring官方的文档介绍，这个过程是比较简单的。集成过程中需要用到的支持mongodb的jar包也不多。主要有：
mongo-java-driver-<span style="color: #.4.<span style="color: #.jar
spring-data-commons-<span style="color: #.10.<span style="color: #.RELEASE.jar
spring-data-commons-core-<span style="color: #.4.<span style="color: #.RELEASE.jar
spring-data-mongodb-<span style="color: #.7.<span style="color: #.RELEASE.jar
上述的jar是我的集成过程中用到的。
我在自己既有的spring mvc的web项目里面，添加了mongodb的支持。
首先看看mongodb的xml配置文件spring-mongo.xml：
&?xml version="<span style="color: #.0" encoding="UTF-8"?&
&beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.2.xsd"
default-lazy-init="default"&
&!--credentials的配置形式是：用户名:密码@默认数据库--&
&mongo:mongo-client id="mongoClient" host="${mongo.host}" port="${mongo.port}"
credentials="${mongo.username}:${mongo.password}@${mongo.dbname}"&
&mongo:client-options
write-concern="SAFE"
connections-per-host="${mongo.connectionsPerHost}"
threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"
connect-timeout="${mongo.connectTimeout}"
max-wait-time="${mongo.maxWaitTime}"
socket-timeout="${mongo.socketTimeout}"/&
&/mongo:mongo-client&
&mongo:db-factory id="mongoDbFactory" dbname="${mongo.dbname}" mongo-ref="mongoClient" /&
&bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"&
&constructor-arg name="mongoDbFactory" ref="mongoDbFactory" /&
其中的参数配置文件mongo.properties:
mongo.dbname=robotkdb
mongo.host=<span style="color: #.90.<span style="color: #.10
mongo.port=<span style="color: #017
mongo.username=robotassister
mongo.password=xxyyyxxxxx
#一个线程变为可用的最大阻塞数
mongo.connectionsPerHost=<span style="color: #
#线程队列数,它以上面connectionsPerHost值相乘的结果就是线程队列最大值
mongo.threadsAllowedToBlockForConnectionMultiplier=<span style="color: #
#连接超时时间（毫秒）
mongo.connectTimeout=<span style="color: #00
#最大等待时间
mongo.maxWaitTime=<span style="color: #00
mongo.autoConnectRetry=true
#scoket保持活动
mongo.socketKeepAlive= true
#scoket超时时间
mongo.socketTimeout=<span style="color: #00
mongo.slaveOk=true
接下来，看看spring的配置文件applicationContext.xml:
&?xml version="<span style="color: #.0" encoding="UTF-8"?&
&beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.2.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"&
&bean id="configRealm" class="org.springframework.beans.factory.config.PropertiesFactoryBean"&
&property name="locations"&
&value&classpath:conf/internal.properties&/value&
&value&classpath:conf/jdbc.properties&/value&
&value&classpath:conf/redis.properties&/value&
&value&classpath:conf/session.properties&/value&
&value&classpath:conf/mongo.properties&/value&
&/property&
&bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer"&
&property name="properties" ref="configRealm"/&
&bean id="springCacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"&
&property name="cacheManager" ref="ehcacheManager"/&
&bean id="ehcacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"&
&property name="configLocation" value="classpath:conf/ehcache.xml"/&
&cache:annotation-driven cache-manager="springCacheManager"/&
&import resource="spring-servlet.xml"/&
&import resource="spring-cache.xml"/&
&import resource="spring-dao.xml"/&
&import resource="spring-redis.xml"/&
&import resource="spring-mongo.xml"/&
ok,到此，所有的配置工作都完毕了，我们就启动web项目，看看是否能正常启动吧！遗憾，出了下面的错误！！！！！

这个，还真是折腾了我一段时间，最终找到原因：
上述这个错误，需要在spring-mongo.xml文件中添加下面的两行内容
http://www.springframework.org/schema/data/repository
http://www.springframework.org/schema/data/repository/spring-repository-1.7.xsd
采用基于mongo:mongo-client标签进行安全配置，mongo要求spring-mongo.xsd必须是1.6及以上的版本。我们这里选用的是1.7.
ok，再次运行看看吧。。。。。。结果如何呢。。。。。。。。。

又出现了错误。。。看来不是很顺利啊，再研究看root cause是什么呢？？？依据
爆出上述错误，经过查找原因，得知，sping-data-mongo要求spring-core必须是4.x的版本，也就是说spring4才行。
源头是通过查找日志中红色部分的错误信息，得知相关的jar依赖文件，在spring-core 4.x的版本中默认含有，于是，将项目中原来3.2的配置信息，全部更新为4.2的，并相应的将工程的lib中spring的版本更新到4.2.再次启动应用。这次，一切都ok了。
最终能正常运行的applicationContext.xml的内容如下：

4. 启用一个测试，验证一下spring和mongodb的集成是否成功吧
先构建一个javabean：
* @author "shihuc"
package com.roomdis.center.mongo.
import java.io.S
import org.ietf.jgss.O
import org.springframework.data.mongodb.core.mapping.D
import org.springframework.data.mongodb.core.mapping.F
* @author chengsh05
@Document(collection="buzz_element")
public class BuzzElement implements Serializable {
private static final long serialVersionUID = <span style="color: #L;
private Oid _
@Field(value="item_id")
private String itemId;
@Field(value="item_name")
private String itemN
@Field(value="price")
@Field(value="desc")
public Oid get_id() {
public void set_id(Oid _id) {
this._id = _
public String getItemId() {
return itemId;
public void setItemId(String itemId) {
this.itemId = itemId;
public String getItemName() {
return itemN
public void setItemName(String itemName) {
this.itemName = itemN
public String getPrice() {
public void setPrice(String price) {
this.price =
public String getDesc() {
public void setDesc(String desc) {
this.desc =
public String toString() {
return "ItemInfo [_id=" + _id + ", itemId=" + itemId + ", itemName="
+ itemName + ", price=" + price + ", desc=" + desc + "]";
再创建工具类BeanUtil：
* @author "shihuc"
package com.roomdis.center.mongo.
import java.lang.reflect.F
import java.lang.reflect.InvocationTargetE
import java.util.D
import mons.beanutils.BeanU
import com.mongodb.BasicDBO
import com.mongodb.DBO
* @author chengsh05
public class BeanUtil {
* 把实体bean对象转换成DBObject
* @param bean
* @throws IllegalArgumentException
* @throws IllegalAccessException
public static &T& DBObject bean2DBObject(T bean) throws IllegalArgumentException,
IllegalAccessException {
if (bean == null) {
return null;
DBObject dbObject = new BasicDBObject();
// 获取对象对应类中的所有属性域
Field[] fields = bean.getClass().getDeclaredFields();
// 获取所有注解
for (Field field : fields) {
org.springframework.data.mongodb.core.mapping.Field anno = field.getAnnotation(org.springframework.data.mongodb.core.mapping.Field.class);
// 获取属性名
String varName = field.getName();
if("serialVersionUID".equals(varName) || "_id".equals(varName)){
// 获取注解的值
varName = anno.value();
// 修改访问控制权限
boolean accessFlag = field.isAccessible();
if (!accessFlag) {
field.setAccessible(true);
Object param = field.get(bean);
if (param == null) {
} else if (param instanceof Integer) {//判断变量的类型
int value = ((Integer) param).intValue();
dbObject.put(varName, value);
} else if (param instanceof String) {
String value = (String)
dbObject.put(varName, value);
} else if (param instanceof Double) {
double value = ((Double) param).doubleValue();
dbObject.put(varName, value);
} else if (param instanceof Float) {
float value = ((Float) param).floatValue();
dbObject.put(varName, value);
} else if (param instanceof Long) {
long value = ((Long) param).longValue();
dbObject.put(varName, value);
} else if (param instanceof Boolean) {
boolean value = ((Boolean) param).booleanValue();
dbObject.put(varName, value);
} else if (param instanceof Date) {
Date value = (Date)
dbObject.put(varName, value);
// 恢复访问控制权限
field.setAccessible(accessFlag);
return dbO
* 把DBObject转换成bean对象
* @param dbObject
* @param bean
* @throws IllegalAccessException
* @throws InvocationTargetException
* @throws NoSuchMethodException
public static &T& T dbObject2Bean(DBObject dbObject, T bean) throws IllegalAccessException,
InvocationTargetException, NoSuchMethodException {
if (bean == null) {
return null;
Field[] fields = bean.getClass().getDeclaredFields();
for (Field field : fields) {
String varName = field.getName();
org.springframework.data.mongodb.core.mapping.Field anno = field.getAnnotation(org.springframework.data.mongodb.core.mapping.Field.class);
if("serialVersionUID".equals(varName) || "_id".equals(varName)){
String fieldName = anno.value();
Object object = dbObject.get(fieldName);
if (object != null) {
BeanUtils.setProperty(bean, varName, object);
再次，创建服务，进行操作数据库，相当于dao层：
* @author "shihuc"
package com.roomdis.center.mongo.
import java.util.L
import org.json.JSONO
import com.roomdis.center.mongo.model.BuzzE

import com.roomdis.center.mongo.util.BeanU
* @author chengsh05
@Service("buzzElementService")
public class BuzzElementServiceImpl implements IBuzzElementService {
@Autowired
private MongoTemplate mongoT
private final static String COLLECTION_NAME = "buzz_element";
/* (non-Javadoc)
* @see com.roomdis.center.mongo.service.IBuzzElementService#getItemInfo(org.json.JSONObject)
public List&BuzzElement& getItemInfo(JSONObject json) throws Exception {
List&BuzzElement& list = new ArrayList&BuzzElement&();
// 判断查询的json中传递过来的参数
DBObject query = new BasicDBObject();
if(json.has("item_id")){
query.put("item_id", json.getString("item_id"));
}else if(json.has("item_name")){
query.put("item_name", json.getString("item_name"));
DBCursor results = mongoTemplate.getCollection(COLLECTION_NAME).find(query);
if(null != results){
Iterator&DBObject& iterator = results.iterator();
while(iterator.hasNext()){
BasicDBObject obj = (BasicDBObject) iterator.next();
BuzzElement itemInfo = new BuzzElement();
itemInfo = BeanUtil.dbObject2Bean(obj, itemInfo);
list.add(itemInfo);
/* (non-Javadoc)
* @see com.roomdis.center.mongo.service.IBuzzElementService#save(com.roomdis.center.mongo.model.BuzzElement)
public int save(BuzzElement itemInfo) throws Exception {
DBCollection collection = this.mongoTemplate.getCollection(COLLECTION_NAME);
int result = <span style="color: #;
DBObject iteminfoObj = BeanUtil.bean2DBObject(itemInfo);
//iteminfoObj.removeField("serialVersionUID");
//result = collection.insert(iteminfoObj).getN();
WriteResult writeResult = collection.save(iteminfoObj);
result = writeResult.getN();
/* (non-Javadoc)
* @see com.roomdis.center.mongo.service.IBuzzElementService#update(com.roomdis.center.mongo.model.BuzzElement)
public void update(BuzzElement intemInfo) throws Exception {
DBCollection collection = this.mongoTemplate.getCollection(COLLECTION_NAME);
BuzzElement queryItemInfo = new BuzzElement();
queryItemInfo.setItemId(intemInfo.getItemId());
DBObject itemInfoObj = BeanUtil.bean2DBObject(intemInfo);
DBObject query =
BeanUtil.bean2DBObject(queryItemInfo);
collection.update(query, itemInfoObj);
郑重说明，上述的javabean以及BeanUtil还有服务程序类，是参照网络资源，考虑到这些东西不是本博的重点，也不是关键，所以没有花时间在这个上面。
最后，我们写一个controller来模拟一下添加数据，查询数据以及更新数据，看看工作流程是否顺畅！

好了，代码都准备ok了，下面进行测试！
A.在浏览器地址栏执行：http://10.90.9.20:8080/RDcenter/mongo/save
数据库得到的数据：
& show collections
buzz_element
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a") }
B. 添加一条数据。在浏览器地址栏里面输入： http://10.90.9.20:8080/RDcenter/mongo/save?itemName=iphone7&price=7000&desc=good product, everyone loves it
数据库得到的数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a") }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
再次添加一条数据，在浏览器地址栏里面输入： http://10.90.9.20:8080/RDcenter/mongo/save?itemName=S8&price=8000&desc=samsung new product
数据库得到的数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a") }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
{ "_id" : ObjectId("<span style="color: #eb1bf8d04d70"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "samsung new product" }
C.查询数据，在浏览器地址栏输入：http://10.90.9.20:8080/RDcenter/mongo/find?itemName=S8
最终，浏览器上得到的返回结果是：
D. 更新数据，在浏览器地址栏输入：http://10.90.9.20:8080/RDcenter/mongo/update?itemName=S8&price=9000&desc=hope it is nice
更新前的数据库数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a"), "item_name" : "iphone7", "desc" : "not everyone will buy it" }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
{ "_id" : ObjectId("<span style="color: #eb1bf8d04d70"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "samsung new product" }
更新后的数据库数据：
& db.buzz_element.find()
{ "_id" : ObjectId("<span style="color: #092f3e0ef2eb286cd7410a"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "hope it is nice" }
{ "_id" : ObjectId("<span style="color: #eb286cd7410b"), "item_name" : "iphone7", "price" : "<span style="color: #00", "desc" : "good product, everyone loves it" }
{ "_id" : ObjectId("<span style="color: #eb1bf8d04d70"), "item_name" : "S8", "price" : "<span style="color: #00", "desc" : "samsung new product" }
从上面看，数据库是更新了，但是貌似有点逻辑问题，将第一个更新了，我们希望是将既有的item_name为S8产品数据更新的，这个是业务逻辑问题，暂且不做修改了。。。
从上面的全部过程来看，基于spring+mongodb的集成工作，完美结束，也很简单。
剩下来的，重点是mongodb的增删改查相关的接口研究，是个熟悉的过程，各位朋友，建议去看官网的资料。}
