mybatis的mapper不允许重载，因为它需要通过方法名称[不加签名]去查找需要执行的sql

1.批量删除

     
          delete from plan_location where uuid in    (
      
                #{item, jdbcType=VARCHAR}    
      )  
     

 2.批量插入

     
          insert into plan_location (uuid, location_name, group_id, x,       y, tenant_id,       create_time, create_user_id, update_user_id      ) values     
      
                (#{item.uuid, jdbcType=VARCHAR}, #{item.locationName,jdbcType=VARCHAR},#{item.groupId,jdbcType=INTEGER},        #{item.x,jdbcType=DOUBLE},#{item.y,jdbcType=DOUBLE},        #{item.tenantId,jdbcType=INTEGER},#{item.createTime,jdbcType=TIMESTAMP},        #{item.createUserId,jdbcType=INTEGER},#{item.createUserId,jdbcType=INTEGER})
