7-1 第一次家庭作业：商品类别列表展示

略

7-2 公布答案：商品类别列表展示从后到前

Dao层：添加queryProductCategoryList

/**
 * 通过shop id查询店铺所有商品类别
 * @param shopId
 * @return
 */
List<ProductCategory> queryProductCategoryList(long shopId);

Mapper层：

<select id="queryProductCategoryList" resultType="com.doit.o2o.entity.ProductCategory" parameterType="Long">
		SELECT product_category_id,product_category_name,priority,create_time,shop_id
		FROM tb_product_category
		WHERE shop_id=#{shopId}
		ORDER BY priority DESC
</select>

Service层：

接口：

List<ProductCategory> getProductCategoryList(long shopId);

实现：

@Override
public List<ProductCategory> getProductCategoryList(long shopId) {
	return productCategoryDao.queryProductCategoryList(shopId);
}

Controller层：

@RequestMapping(value="/getproductcategorylist",method=RequestMethod.GET)
	@ResponseBody
	private Result<List<ProductCategory>> getProductCategoryList(HttpServletRequest request){
		
//		Shop shop = new Shop();
//		shop.setShopId(1L);
//		request.getSession().setAttribute("currentShop", shop);
		
		//从店铺管理页面进入，getShopManagementInfo方法已在session中设置了currentShop的值
		Shop currentShop = (Shop)request.getSession().getAttribute("currentShop");
		
		List<ProductCategory> list = null;
		if(currentShop!=null&&currentShop.getShopId()>0){
			list = productCategoryService.getProductCategoryList(currentShop.getShopId());
			return new Result<List<ProductCategory>>(true,list);
		}else{
			ProductCategoryStateEnum ps = ProductCategoryStateEnum.INNER_ERROR;
			return new Result<List<ProductCategory>>(false,ps.getState(),ps.getStateInfo());
		}
	}

7-3 商品类别批量添加后端开发

Dao层：

/**
 * 批量新增商品类别
 * @param productCategoryList
 * @return
 */
int batchInsertProductCategory(List<ProductCategory> productCategoryList);

Mapper层：

<insert id="batchInsertProductCategory" parameterType="java.util.List">
		INSERT INTO tb_product_category(product_category_name,priority,create_time,shop_id)
		VALUES
		<foreach collection="list" item="productCategory" index="index" separator=",">
		(
		#{productCategory.productCategoryName},
		#{productCategory.priority},
		#{productCategory.createTime},
		#{productCategory.shopId}
		)
		</foreach>
</insert>

Service层：

ProductCategoryExecution batchAddProductCategoryList(List<ProductCategory> productCategoryList);

@Override
	@Transactional
	public ProductCategoryExecution batchAddProductCategoryList(List<ProductCategory> productCategoryList) {
		if(productCategoryList!=null&&productCategoryList.size()>0){
			try {
				int effectedNum = productCategoryDao
						.batchInsertProductCategory(productCategoryList);
				if (effectedNum <= 0) {
					throw new RuntimeException("店铺类别失败");
				} else {

					return new ProductCategoryExecution(
							ProductCategoryStateEnum.SUCCESS);
				}

			} catch (Exception e) {
				throw new RuntimeException("batchAddProductCategory error: "
						+ e.getMessage());
			}
		}else{
			return new ProductCategoryExecution(ProductCategoryStateEnum.EMPTY_LIST);
		}
	}

Controller层：

@RequestMapping(value = "/addproductcategories", method = RequestMethod.POST)
	@ResponseBody
	private Map<String,Object> addProductCategories(@RequestBody List<ProductCategory> productCategoryList
			,HttpServletRequest request){
		Map<String,Object> modelMap = new HashMap<String,Object>();
		Shop currentShop = (Shop)request.getSession().getAttribute("currentShop");
		long currentShopId = currentShop.getShopId();
		for(ProductCategory productCategory:productCategoryList){
			productCategory.setShopId(currentShopId);
		}
		if(productCategoryList!=null&&productCategoryList.size()>0){
			try{
				ProductCategoryExecution pe = productCategoryService.batchAddProductCategoryList(productCategoryList);
				if(pe.getState()==ProductCategoryStateEnum.SUCCESS.getState()){
					modelMap.put("success", true);
				}else {
					modelMap.put("success", false);
					modelMap.put("errMsg", pe.getStateInfo());
				}
			}catch(RuntimeException e) {
				modelMap.put("success", false);
				modelMap.put("errMsg", e.toString());
				return modelMap;
			}
		}else{
			modelMap.put("success", false);
			modelMap.put("errMsg", "请至少输入一个商品类别");
		}
		return modelMap;
	}

7-5 商品类别删除后端开发

Dao层：

/**
 * 删除商品类别（初版，即只支持删除尚且没有发布商品的商品类别）
 * @param productCategoryId
 * @param shopId
 * @return
 */
int deleteProductCategory(@Param("productCategoryId") long productCategoryId,@Param("shopId") long shopId);

Mapper层：

<delete id="deleteProductCategory">
		<!-- 具体的sql -->
		DELETE FROM tb_product_category
		WHERE product_category_id = #{productCategoryId}
		AND shop_id=#{shopId}
</delete>

Service层：

/**
 * 将此类别下的商品的类别id置为空，再删除掉该商品类别
 * @param productCategoryId
 * @param shopId
 * @return
*/
ProductCategoryExecution deleteProductCategory(long productCategoryId,long shopId);

@Override
	@Transactional
	public ProductCategoryExecution deleteProductCategory(long productCategoryId, long shopId) 
		throws ProductCategoryOperationException{
		//TODO将此商品类别下的商品的类别Id置为空
		try{
			int effectedNum = productCategoryDao.deleteProductCategory(productCategoryId, shopId);
			if(effectedNum<=0){
				throw new RuntimeException("商品类别删除失败");
			}else{
				return new ProductCategoryExecution(ProductCategoryStateEnum.SUCCESS);
			}
		}catch(Exception e){
			throw new RuntimeException("deleteProductCategory error: "
					+ e.getMessage());
		}
	}

Controller层：

@RequestMapping(value = "/removeproductcategory", method = RequestMethod.POST)
	@ResponseBody
	private Map<String,Object> removeProductCategory(Long productCategoryId,HttpServletRequest request){
		Map<String,Object> modelMap = new HashMap<String,Object>();
		
		if(productCategoryId!=null&&productCategoryId>0){
			try{
				Shop currentShop = (Shop)request.getSession().getAttribute("currentShop");
				long currentShopId = currentShop.getShopId();
				ProductCategoryExecution pe = productCategoryService.deleteProductCategory(productCategoryId, currentShopId);
				if(pe.getState()==ProductCategoryStateEnum.SUCCESS.getState()){
					modelMap.put("success", true);
				}else {
					modelMap.put("success", false);
					modelMap.put("errMsg", pe.getStateInfo());
				}
			}catch(RuntimeException e) {
				modelMap.put("success", false);
				modelMap.put("errMsg", e.toString());
				return modelMap;
			}
		}else{
			modelMap.put("success", false);
			modelMap.put("errMsg", "请至少选择一个商品类别");
		}
		return modelMap;
	}
