Zebra分库分表的使用

<bean id="shardDataSource" class="com.dianping.zebra.shard.jdbc.ShardDataSource" init-method="init">
        <!-- lion配置方式，需配置shardds.xxx.shard项value为json格式 --> //所以实际对应的rule的配置的key是shardds.trade.shard
        <property name="ruleName" value="trade"/>

        <!-- 主动配置分库，lion配置下可选，xml配置必输 -->
        <property name="dataSourcePool">//这里能做分库的原因就是用一个map就可以配多个数据库了
            <map>
                <entry key="ds0" value-ref="dataSource2"/><!-- 该处的key即为配置里面的dbIndexes --> // ds0可以根据开发习惯起名的，也可以叫db0...
            </map>
        </property>
