spring Ibatis Mysql ReplicationDriver

Question

我使用了Spring3.1ibati2.x和mysql5.5。然后我想使用复制驱动程序。

我的代码是：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.ReplicationDriver" />
    <property name="url" value="jdbc:mysql:replication://192.168.1.160:3306/test,192.168.1.160:3306/test" />
    <property name="username" value="root" />
    <property name="password" value="root" />
.....

然后：

Caused by: org.apache.commons.dbcp.SQLNestedException: 
Cannot create PoolableConnectionFactory (Must specify at least one slave host to connect to for master/slave replication load-balancing functionality)
at org.apache.commons.dbcp.BasicDataSource.createPoolableConnectionFactory(BasicDataSource.java:1549)

那么如何让ibatis支持复制呢？

Answer 1

尝尝这个

<property name="url" value="jdbc:mysql:replication://192.168.1.160:3306,192.168.1.160:3306/test" />

格式为: master、slave1、slave2

为什么你要使用相同的服务器来进行负载均衡。
