依赖加入如下：  
spring版本

<dependency>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-mongodb</artifactId>
                <version>1.8.2.RELEASE</version>
            </dependency>
    
            
            <dependency>
                <groupId>org.mongodb</groupId>
                <artifactId>mongo-java-driver</artifactId>
                <version>2.14.3</version>
            </dependency>

说明要注意兼容问题，spring 4.2.0.RELEASE下只能用org.springframework.data 1.8.2.RELEASE  
如果是spring 4.2的可以用 org.springframework.data 1.92.RELEASE

依赖加好了：之后需要在spring中加入Monggodb的的使用，和注入，见配置如下：  
这是全部的，可在spring中直接引用这个配置文件

<?xml version="1.0" 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" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">
    
    
    
        
       <mongo:mongo id="mongo" replica-set="${mongo.hostport}">
                
            <mongo:options connections-per-host="${mongo.connectionsPerHost}" threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}" connect-timeout="${mongo.connectTimeout}" max-wait-time="${mongo.maxWaitTime}" auto-connect-retry="${mongo.autoConnectRetry}" socket-keep-alive="${mongo.socketKeepAlive}" socket-timeout="${mongo.socketTimeout}" slave-ok="${mongo.slaveOk}" write-number="1" write-timeout="0" write-fsync="true"/>        
          </mongo:mongo>
            
            <mongo:db-factory dbname="mongodb" mongo-ref="mongo"/>  
            <mongo:mapping-converter id="converter" db-factory-ref="mongoDbFactory"/>
    
              
              <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate" >   
              <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />  
               <constructor-arg ref="converter"/>
            </bean>  
            
            <bean id="gridTemplate" class="org.springframework.data.mongodb.gridfs.GridFsTemplate">
            <constructor-arg ref="mongoDbFactory"/>
            <constructor-arg ref="converter"/>
            </bean>
    
    </beans>

里面配置参数如下：

mongo.hostport=127.0.0.1:27017
    mongo.connectionsPerHost=8
    mongo.threadsAllowedToBlockForConnectionMultiplier=4
    #\u8FDE\u63A5\u8D85\u65F6\u65F6\u95F4
    mongo.connectTimeout=1000
    #\u7B49\u5F85\u65F6\u95F4
    mongo.maxWaitTime=1500
    mongo.autoConnectRetry=true
    mongo.socketKeepAlive=true
    #Socket\u8D85\u65F6\u65F6\u95F4
    mongo.socketTimeout=1500
    mongo.slaveOk=true

之后可在spring中使用 mongoTemplate来实现crud操作，和mongoTemplate.getDb();来操作文件的上传和下载
