4種貨物,如何使用一個接口實現CRUD:前端
package com.tansuo365.test1.service.goods; import com.tansuo365.test1.entity.Goods; import com.tansuo365.test1.mapper.goods.IGoodsCommonMapper; import java.util.List; /** * 貨品公用service接口 * {@link #setGoodsTypeMapper 設置貨品類型} * {@link #delete 刪除單條元組} * {@link #deleteBatchByPKs 批量刪除} * {@link #addBySelective 單條動態錄入} * {@link #insertBatchList 批量錄入} */ public interface IGoodsCommonService { public void setGoodsTypeMapper(IGoodsCommonMapper goodsTypeMapper); public IGoodsCommonMapper getGoodsTypeMapper(); //根據主鍵刪除 public Integer delete(Long id); //根據主鍵批量刪除 public Integer deleteBatchByPKs(Long[] ids); //錄入(動態) public Integer addBySelective(Goods goods); //批量錄入 public Integer insertBatchList(List<Goods> list); //按需獲取 public List<Goods> getBySelective(Goods goods); //選擇所有 public List<Goods> getAll(); //動態更新 public Integer updateBySelective(Goods goods); }
實現java
