i had use the spring3.1 ibatis2.x and mysql5.5. then i wanna use the replication driver .

my code is:

<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" />
.....

then：

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)

Try this

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

The format is : master,slave1,slave2
Don't why you taking same server for load balancing.
