遇到问题

SpringMVC的项目中使用spring-data-mongodb驱动包进行读写mongodb。
包的pom.xml如下


	<dependency>
			<groupId>org.springframework.data</groupId>
			<artifactId>spring-data-mongodb</artifactId>
			<version>1.9.1.RELEASE</version>
		</dependency>

mongdb.xml配置如下:

  <mongo:mongo-client id="logMongoClient" host="${mongo.log.server}" port="${mongo.log.port}" >
  		<!-- com.mongodb.MongoClientOptions -->
  		<mongo:client-options
  			connections-per-host="${mongo.log.connectionsPerHost}"
    	 	threads-allowed-to-block-for-connection-multiplier="${mongo.log.threadsAllowedToBlockForConnectionMultiplier}"
     		connect-timeout="${mongo.log.connectTimeout}"
     		max-wait-time="${mongo.log.maxWaitTime}"
     		socket-keep-alive="${mongo.log.socketKeepAlive}"
     		socket-timeout="${mongo.log.socketTimeout}"
     		max-connection-life-time="${mongo.log.connectLifeTime}"/>
	 </mongo:mongo-client>
     <mongo:db-factory id="logMongoDbFactory"
                  dbname="${mongo.log.db}"    
                  username="${mongo.log.user}"    
                  password="${mongo.log.password}"
                  mongo-ref="logMongoClient"/>
     <bean id="logMongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
     	 <constructor-arg name="mongoDbFactory" ref="logMongoDbFactory"/>  
     </bean>

参数配置如下:

#log mongodb
mongo.log.user=test
mongo.log.password=
mongo.log.server=192.168.30.11
mongo.log.port=28717
mongo.log.db=db_log

mongo.log.connectionsPerHost=100
mongo.log.threadsAllowedToBlockForConnectionMultiplier=5
mongo.log.connectTimeout=10000
mongo.log.maxWaitTime=120000 
mongo.log.socketKeepAlive=false
mongo.log.socketTimeout=0
#1 hour
mongo.log.connectLifeTime=3600000

mongodb服务更改为副本集，增加账号密码后使用原配置连接报错如下:

Constructor threw exception; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Usage of 'UserCredentials' with 'MongoClient' is no longer supported. Please use 'MongoCredential' for 'MongoClient' or just 'Mongo'.

原因

配置过时，当前配置不符合集群副本集的认证机制。

旧的配置在单机模式下带账号密码认证是ok的，可以正常访问。
但是修改成副本集模式之后，这种配置无效。根据提示，应该使用MongoCredential的认证配置。
或者只使用mongo模式。

解决方式

方式一monogo模式

使用简单的mongo模式配置如下:

    <mongo:db-factory id="logMongoDbFactory"    
                  host="${mongo.log.server}"    
                  port="${mongo.log.port}"    
                  dbname="${mongo.log.db}"    
                  username="${mongo.log.user}"    
                  password="${mongo.log.password}"/>      
     <bean id="logMongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
     	 <constructor-arg name="mongoDbFactory" ref="logMongoDbFactory"/>  
     </bean>

方式二 mongoClient模式

mongoClient模式是比较新的配置方式，可以带更多的参数，在原配置基础上只需要调整一下账号密码的配置方式如下:

  <mongo:mongo-client id="logMongoClient" host="${mongo.log.server}" port="${mongo.log.port}"  credentials="${mongo.log.user}:${mongo.log.password}@${mongo.log.db}">
  		<!-- com.mongodb.MongoClientOptions -->
  		<mongo:client-options
  			connections-per-host="${mongo.log.connectionsPerHost}"
    	 	threads-allowed-to-block-for-connection-multiplier="${mongo.log.threadsAllowedToBlockForConnectionMultiplier}"
     		connect-timeout="${mongo.log.connectTimeout}"
     		max-wait-time="${mongo.log.maxWaitTime}"
     		socket-keep-alive="${mongo.log.socketKeepAlive}"
     		socket-timeout="${mongo.log.socketTimeout}"
     		max-connection-life-time="${mongo.log.connectLifeTime}"/>
	 </mongo:mongo-client>
     <mongo:db-factory id="logMongoDbFactory"
	             dbname="${mongo.log.db}"
                  mongo-ref="logMongoClient"/>
     <bean id="logMongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
     	 <constructor-arg name="mongoDbFactory" ref="logMongoDbFactory"/>  
     </bean>

如果是副本集，则使用如下配置:

  <mongo:mongo-client id="logMongoClient" replica-set="${mongo.log.host}:${mongo.log.port}"  credentials="${mongo.log.user}:${mongo.log.password}@${mongo.log.db}">
  		<!-- com.mongodb.MongoClientOptions -->
  		<mongo:client-options
  			connections-per-host="${mongo.log.connectionsPerHost}"
    	 	threads-allowed-to-block-for-connection-multiplier="${mongo.log.threadsAllowedToBlockForConnectionMultiplier}"
     		connect-timeout="${mongo.log.connectTimeout}"
     		max-wait-time="${mongo.log.maxWaitTime}"
     		socket-keep-alive="${mongo.log.socketKeepAlive}"
     		socket-timeout="${mongo.log.socketTimeout}"
     		max-connection-life-time="${mongo.log.connectLifeTime}"/>
	 </mongo:mongo-client>
     <mongo:db-factory id="logMongoDbFactory"
	             dbname="${mongo.log.db}"
                  mongo-ref="logMongoClient"/>
     <bean id="logMongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
     	 <constructor-arg name="mongoDbFactory" ref="logMongoDbFactory"/>  
     </bean>

注意事项

注意集群下连接的mongodb的host为主服务器的地址，而非从服务器的地址。
然后mongo:db-factory需要带 dbname参数，即使credentials=" ${mongo.log.user}:$ {mongo.log.password}@${mongo.log.db}"中已经带了db的参数，但是这个是认证用的。
否则会报错无法通过认证。
