遇到問題

SpringMVC的專案中使用spring-data-mongodb驅動包進行讀寫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>
 

引數配置如下:

#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服務更改為副本集，增加賬號密碼後使用原配置連線報錯如下:

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

配置過時，當前配置不符合叢集副本集的認證機制。

舊的配置在單機模式下帶賬號密碼認證是ok的，可以正常訪問。
但是修改成副本集模式之後，這種配置無效。根據提示，應該使用MongoCredential的認證配置。
或者只使用mongo模式。

解決方式

方式一monogo模式

使用簡單的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模式是比較新的配置方式，可以帶更多的引數，在原配置基礎上只需要調整一下賬號密碼的配置方式如下:

  <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，則使用如下配置:

  <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>

注意事項

注意叢集下連線的mongodb的host為主伺服器的地址，而非從伺服器的地址。
然後mongo:db-factory需要帶 dbname引數，即使credentials="${mongo.log.user}:${mongo.log.password}@${mongo.log.db}"中已經帶了db的引數，但是這個是認證用的。
否則會報錯無法通過認證。
