概述

上篇博客 實戰(zhàn)SSM_O2O商鋪_26【商品類別】批量新增商品類別從Dao到View層的開發(fā)實現(xiàn)了商品目錄的批量添加功能，我們按照既定的設(shè)計，繼續(xù)來完成商品目錄的修改吧。

ProductCategoryDao接口增加接口方法

/*** * * @Title: deleteProductCategory* * @Description: 刪除特定shop下的productCategory* * @param productCategoryId* @param shopId* * @return: int*/int deleteProductCategory(@Param("productCategoryId") Long productCategoryId, @Param("shopId") Long shopId);

ProductCategoryDao SQL映射文件

<delete id="deleteProductCategory">DELETE FROM tb_product_categoryWHERE product_category_id = #{productCategoryId}and shop_id = #{shopId}</delete>

閉環(huán)的單元測試

這里我們使用Junit 4.11里及其以后的版本中增加的@FixMethodOrder注解來實現(xiàn). 具體見代碼注釋。

package com.artisan.o2o.dao;import static org.junit.Assert.assertEquals;import java.util.ArrayList; import java.util.Date; import java.util.List;import org.junit.Assert; import org.junit.FixMethodOrder; import org.junit.Test; import org.junit.runners.MethodSorters; import org.springframework.beans.factory.annotation.Autowired;import com.artisan.o2o.BaseTest; import com.artisan.o2o.entity.ProductCategory;/*** * * @ClassName: ProductCategoryTest* * @Description: Junit 4.11里增加了指定測試方法執(zhí)行順序的特性 .* * 測試類的執(zhí)行順序可通過對測試類添加注解@FixMethodOrder(value) 來指定,其中value 為執(zhí)行順序* * 三種執(zhí)行順序可供選擇：* * 默認(rèn)（MethodSorters.DEFAULT）,* 默認(rèn)順序由方法名hashcode值來決定，如果hash值大小一致，則按名字的字典順序確定* 由于hashcode的生成和操作系統(tǒng)相關(guān)* (以native修飾），所以對于不同操作系統(tǒng)，可能會出現(xiàn)不一樣的執(zhí)行順序，在某一操作系統(tǒng)上，多次執(zhí)行的順序不變* * 按方法名（ MethodSorters.NAME_ASCENDING）【推薦】,* 按方法名稱的進(jìn)行排序，由于是按字符的字典順序，所以以這種方式指定執(zhí)行順序會始終保持一致；* 不過這種方式需要對測試方法有一定的命名規(guī)則，如 測試方法均以testNNN開頭（NNN表示測試方法序列號 001-999）* * JVM（MethodSorters.JVM）* 按JVM返回的方法名的順序執(zhí)行，此種方式下測試方法的執(zhí)行順序是不可預(yù)測的，即每次運行的順序可能都不一樣* * * @author: Mr.Yang* * @date: 2018年6月21日 下午11:55:45*/ @FixMethodOrder(MethodSorters.NAME_ASCENDING) public class ProductCategoryTest extends BaseTest {@AutowiredProductCategoryDao productCategoryDao;@Testpublic void testB_SelectProductCategoryList() {long shopId = 5L;List<ProductCategory> productCategories = productCategoryDao.selectProductCategoryList(shopId);// shopId = 5 有2條測試數(shù)據(jù),期望list中有2條assertEquals(2, productCategories.size());// SQL中按照權(quán)重排序, product1 priority 99 ,期望第一條數(shù)據(jù)是 product1assertEquals("product1", productCategories.get(0).getProductCategoryName());for (ProductCategory productCategory : productCategories) {System.out.println(productCategory.toString());}productCategories = productCategoryDao.selectProductCategoryList(6L);assertEquals(0, productCategories.size());}@Testpublic void testA_BatchInsertProductCategory() {ProductCategory productCategory1 = new ProductCategory();productCategory1.setProductCategoryName("product1");productCategory1.setProductCategoryDesc("product1_desc");productCategory1.setPriority(99);productCategory1.setCreateTime(new Date());productCategory1.setLastEditTime(new Date());productCategory1.setShopId(5L);ProductCategory productCategory2 = new ProductCategory();productCategory2.setProductCategoryName("product2");productCategory2.setProductCategoryDesc("product2_desc");productCategory2.setPriority(98);productCategory2.setCreateTime(new Date());productCategory2.setLastEditTime(new Date());productCategory2.setShopId(5L);List<ProductCategory> productCategoryList = new ArrayList<ProductCategory>();productCategoryList.add(productCategory1);productCategoryList.add(productCategory2);int effectNum = productCategoryDao.batchInsertProductCategory(productCategoryList);Assert.assertEquals(2, effectNum);}@Testpublic void testC_DeleteProductCategory() {// 查詢出來shopId=5的商鋪下面全部的商品目錄List<ProductCategory> productCategoryList = productCategoryDao.selectProductCategoryList(5L);// 遍歷循環(huán)刪除for (ProductCategory productCategory : productCategoryList) {if ("product1".equals(productCategory.getProductCategoryName()) || "product2".equals(productCategory.getProductCategoryName())) {int effectNum = productCategoryDao.deleteProductCategory(productCategory.getProductCategoryId(), 5L);assertEquals(1, effectNum);}}}}

單元測試

前端完成后，一起測試

View層

productcategorymanage.js

增加如下代碼

var deleteProductCategoryUrl = '/o2o/shopadmin/removeproductcategory';// 一種是需要提交到后臺的刪除 now ，另外一種是 新增但未提交到數(shù)據(jù)庫中的刪除 temp$('.product-categroy-wrap').on('click', '.row-product-category.now .delete',function(e) {var target = e.currentTarget;$.confirm('確定么?', function() {$.ajax({url : deleteProductCategoryUrl,type : 'POST',data : {productCategoryId : target.dataset.id,},dataType : 'json',success : function(data) {if (data.success) {$.toast('刪除成功！');// 重新加載數(shù)據(jù)getProductCategoryList();} else {$.toast('刪除失敗！');}}});});});$('.product-categroy-wrap').on('click', '.row-product-category.temp .delete',function(e) {$(this).parent().parent().remove();});

聯(lián)調(diào)

前端頁面debug, 后端也可以加入斷點，以debug的方式開啟tomcat，逐步調(diào)測

效果如下：
