Using MySQL replication (Master/Slave) with MyBatis

问题

I am just wondering how I can use a Master/Slave MySQL replication database with MyBatis. JDBC offers a com.mysql.jdbc.ReplicationDriver (see here), but I couldn't find out where I can use similar things including all the nice properties I can configure (roundRobinLoadBalance, autoReconnect,...) in MyBatis.

Currently I have configured my none-replicated database in MyBatis like this:

<environments default="development">
    <environment id="development">
        <transactionManager type="JDBC" />
        <dataSource type="POOLED">
            <property name="driver" value="com.mysql.jdbc.Driver" />
            <property name="url"
                value="jdbc:mysql://localhost:3306/database" />
            <property name="username" value="root" />
            <property name="password" value="" />
        </dataSource>
    </environment>
    <environment id="production">
        <transactionManager type="JDBC" />
        <dataSource type="POOLED">
            <property name="driver" value="com.mysql.jdbc.Driver" />
            <property name="url"
                value="jdbc:mysql://xxx:3306/database" />
            <property name="username" value="production" />
            <property name="password" value="" />
        </dataSource>
    </environment>
</environments>

Has anyone a a hint for me?

Thanks for your help.

ANOTHER POSSIBLE ANSWER

If you notice, the properties you're setting in the xml for the driver are also common properties set and passed to jdbc. So, I wouldn't be surprised if MyBatis was just taking them and passing them right into the driver. So maybe try this:

<environments default="development">
    <environment id="development">
        <transactionManager type="JDBC" />
        <dataSource type="POOLED">
            <!-- Just use ReplicationDriver -->
            <property name="driver" value="com.mysql.jdbc.ReplicationDriver" />
            <property name="url"
                value="jdbc:mysql://localhost:3306/database" />
            <property name="autoReconnect" value="true" />
            <property name="roundRobinLoadBalance" value="true" />
            <property name="username" value="root" />
            <property name="password" value="" />
        </dataSource>
    </environment>
    <environment id="production">
        <transactionManager type="JDBC" />
        <dataSource type="POOLED">
            <!-- Just use ReplicationDriver -->
            <property name="driver" value="com.mysql.jdbc.ReplicationDriver" />
            <property name="url"
                value="jdbc:mysql://xxx:3306/database" />
            <property name="autoReconnect" value="true" />
            <property name="roundRobinLoadBalance" value="true" />
            <property name="username" value="production" />
            <property name="password" value="" />
        </dataSource>
    </environment>
</environments>
