概述

上篇博客 实战SSM_O2O商铺_26【商品类别】批量新增商品类别从Dao到View层的开发实现了商品目录的批量添加功能，我们按照既定的设计，继续来完成商品目录的修改吧。

Dao层

ProductCategoryDao接口增加接口方法

/**
	 * 
	 * 
	 * @Title: deleteProductCategory
	 * 
	 * @Description: 删除特定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_category
		WHERE 
			product_category_id = #{productCategoryId}
			and 
			shop_id = #{shopId}
	</delete>

闭环的单元测试

这里我们使用Junit 4.11里及其以后的版本中增加的@FixMethodOrder注解来实现. 具体见代码注释。

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里增加了指定测试方法执行顺序的特性 .
 * 
 *               测试类的执行顺序可通过对测试类添加注解@FixMethodOrder(value) 来指定,其中value 为执行顺序
 * 
 *               三种执行顺序可供选择：
 * 
 *               默认（MethodSorters.DEFAULT）,
 *               默认顺序由方法名hashcode值来决定，如果hash值大小一致，则按名字的字典顺序确定
 *               由于hashcode的生成和操作系统相关
 *               (以native修饰），所以对于不同操作系统，可能会出现不一样的执行顺序，在某一操作系统上，多次执行的顺序不变
 * 
 *               按方法名（ MethodSorters.NAME_ASCENDING）【推荐】,
 *               按方法名称的进行排序，由于是按字符的字典顺序，所以以这种方式指定执行顺序会始终保持一致；
 *               不过这种方式需要对测试方法有一定的命名规则，如 测试方法均以testNNN开头（NNN表示测试方法序列号 001-999）
 * 
 *               JVM（MethodSorters.JVM）
 *               按JVM返回的方法名的顺序执行，此种方式下测试方法的执行顺序是不可预测的，即每次运行的顺序可能都不一样

接口实现

/**

	 */
	@Override
	@Transactional
	public ProductCategoryExecution deleteProductCategory(long productCategoryId, long shopId) throws ProductCategoryOperationException {

单元测试

@Test
	public void testDeleteProductCategory() {

		ProductCategoryExecution productCategoryExecution = productCategoryService.deleteProductCategory(26, 5);
		Assert.assertEquals(1, productCategoryExecution.getState());
		ProductCategoryExecution productCategoryExecution2 = productCategoryService.deleteProductCategory(27, 5);

		} else {
			modelMap.put("success", false);
			modelMap.put("errMsg", "请选择商品类别");
		}
		return modelMap;
	}

单元测试

前端完成后，一起测试

View层

productcategorymanage.js

增加如下代码

 var deleteProductCategoryUrl = '/o2o/shopadmin/removeproductcategory';

// 一种是需要提交到后台的删除  now  ，另外一种是 新增但未提交到数据库中的删除 temp
	
	$('.product-categroy-wrap').on('click', '.row-product-category.now .delete',
			function(e) {
				var target = e.currentTarget;
				$.confirm('确定么?', function() {
					$.ajax({
						url : deleteProductCategoryUrl,
						type : 'POST',
						data : {
							productCategoryId : target.dataset.id,
						},
						dataType : 'json',
						success : function(data) {
							if (data.success) {
								$.toast('删除成功！');
								// 重新加载数据
								getProductCategoryList();
							} else {
								$.toast('删除失败！');
							}
						}
					});
				});
			});

	$('.product-categroy-wrap').on('click', '.row-product-category.temp .delete',
			function(e) {
				$(this).parent().parent().remove();
			});

联调

前端页面debug, 后端也可以加入断点，以debug的方式开启tomcat，逐步调测

效果如下：
