sharding分库分表，使用插件进行sql查询

   <sharding:data-source id="shardingDataSource">
        <sharding:sharding-rule data-source-names="writeDataSource">
         <sharding:table-rules>
         	 <sharding:table-rule logic-table="t_debitcore_repay_order_flow_his"
                                     table-strategy-ref="repayHistroyStrategy"
                                     actual-data-nodes="writeDataSource.t_debitcore_repay_order_flow_his_$->{0..1}$->{0..9}" />
          sharding:table-rules>
  <sharding:standard-strategy id="repayHistroyStrategy" sharding-column="created_at"
                                precise-algorithm-ref="repayHistroyAlgorithm" range-algorithm-ref="repayHistroyAlgorithmRange"/>

<bean id="repayHistroyAlgorithmRange" class=“RepayHistroyTableStrategyRange”/>
<bean id="repayHistroyAlgorithm" class="RepayHistroyTableStrategy"/>

java bean 查询转换类
