spring4.0 配置mongo3.0集群

#在mongo3.0集群,使用副本集群方式.

pom.xml 加引mongo 3.0 ,spring 版本是4.以上我这里使用提4.2.1.RELEASE

     <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>1.8.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongo-java-driver</artifactId>
        <version>3.1.0</version>
    </dependency>

 如果不引用mongo-java-driver 其默加自动导入mongo2.0的驱动.  mongo2的驱动

这里给提供一个mongo2.0spring配置.

                socket-timeout="${mongo.socketTimeout}"
                slave-ok="${mongo.slaveOk}"
                write-number="1"
                write-timeout="1000"
                write-fsync="true"/>
    </mongo:mongo>
    <mongo:db-factory id="mongoDbFactory"  dbname="${mongo.dbname}" mongo-ref="mongo" username="${mongo.username}" password="${mongo.password}" />

    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
    </bean>    
    </beans>

在使用mongo3.0后,这种配置方式,就不支持,官户提给出的解决方法
```
 <mongo:mongo-client id="mongoClient" host="192.168.3.98" port="27017" credentials="用户名:密码@拥有权限的数据库">
  <mongo:mongo-client>
 这种方式,也同样会没有权限,
```
开始以为使用replica-set="127.0.0.1:27001,127.0.0.1:27002,127.0.0.1:27003" 这种方式可以,这种方式在未使用mongo权限时,好像没有什么问题,mongo启动授权后.就会提供没有权限.

mongo3.0 使用Spring需要使用4.0以上的版本,mongo3.集群使用权限,
