xml、 Dao service 三层参数以及对应关系

=======service   调用dao用params.put(K,Value);将参数传入后台。

　　

BaseResponse response = new BaseResponse();
Map<String,Object> params = new HashMap<String,Object>();
String queryByDay = byday.replaceAll("-","/");
List<OrderDateQueryList> result = null;
params.put("masterId", masterId);
params.put("firstDay", queryByDay);
params.put("lastDay", queryByDay);
try {
result = orderDateQueryDao.findWorkOrderListByMonth(params);
response.setData(result);
response.setInfo(ReturnCode.OK);
response.setReturnCode(ReturnCode.STATUS_200);

=====Dao

public interface OrderDateQueryDao {
List<OrderDateQueryList> findWorkOrderListByMonth(Map<String,Object> params) throws Exception;
}
