sharding-jdbc.1.5.0 配置default-data-source无效?报错

数据源配置：

<bean id="dataSource" class="com.qbao.dling.dao.datasource.QbaoDataSource" ><!-- 读写分离配置 -->
   <property name="targetDataSources">
      <map key-type="java.lang.String">
         <entry value-ref="MASTER_TV_DATA_SOURCE" key="MASTER_TV_DATA_SOURCE"></entry>
         <entry value-ref="SLAVE_TV_DATA_SOURCE" key="SLAVE_TV_DATA_SOURCE"></entry>
      </map>
   </property>
   <property name="defaultTargetDataSource" ref="MASTER_TV_DATA_SOURCE" >
   </property>
</bean>

<rdb:strategy id="clockAlgorithm" sharding-columns="user_id" algorithm-class="com.qbao.dling.qbaolive.argorithm.SingleKeyModuloTableShardingAlgorithm" />
<rdb:data-source id="shardingDataSource" >
   <rdb:sharding-rule data-sources="dataSource" default-data-source="dataSource">
      <rdb:table-rules>
         <rdb:table-rule logic-table="td_clock_log" actual-tables="td_clock_log_0${0..9}" table-strategy="clockAlgorithm" />
      </rdb:table-rules>
   </rdb:sharding-rule>
</rdb:data-source>

执行的SQL：

<insert id="add" parameterType="TvShieldInfo">
    <selectKey resultType="long" order="AFTER" keyProperty="id">
        SELECT LAST_INSERT_ID() AS id
    </selectKey>
    INSERT INTO td_broadcast_shield_info
    (user_id,shield_user_id,state,create_time,update_time)
    VALUES(#{userId},#{shieldUserId},#{state},now(),now())
</insert>

应该是SELECT LAST_INSERT_ID() AS id引起的问题。
