2.商品–创建实体类
创建com.cy.store.entity.Product类，并继承BaseEntity类。在类中声明与数据科中对应的属性。
/** 商品数据的实体类 */
public class Product extends BaseEntity implements Serializable {private Integer id;private Integer categoryId;private String itemType;private String title;private String sellPoint;private Long price;private Integer num;private String image;private Integer status;private Integer priority;//****
}
Product
3.商品热销排行–持久层
3.1 规划查询的SQL语句
查询热销商品列表的SQL语句。
SELECT * FORM t_product WHERE status=1 ORDER BY piority DESC LIMIT 0,4
3.2 接口与抽象方法
package com.cy.store.mapper;import com.cy.store.entity.Product;import java.util.List;public interface ProductMapper {/* 查询热销商品的前四名*/List<Product> findHotList();
}3.3 配置SQL映射
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cy.store.mapper.ProductMapper"><resultMap id="ProductEntityMap" type="com.cy.store.entity.Product"><id column="id" property="id"/><result column="category_id" property="categoryId"/><result column="item_type" property="itemType"/><result column="sell_point" property="sellPoint"/><result column="created_user" property="createdUser"/><result column="created_time" property="createdTime"/><result column="modified_user" property="modifiedUser"/><result column="modified_time" property="modifiedTime"/></resultMap><!-- 查询热销商品的前四名：List<Product> findHostList() --><select id="findHotList" resultMap="ProductEntityMap">SELECT * FROM t_product WHERE status=1 ORDER BY priority DESC LIMIT 0,4</select></mapper>ProductMapper–findHotList
4.商品热销排行–业务层
4.1 规划异常
说明：无异常
4.2 实现接口与抽象方法
package com.cy.store.service;import com.cy.store.entity.Product;import java.util.List;/* 处理商品数据的业务层接口 */
public interface IProductService {/*查询热销商品的前四名*/List<Product> findHotList();}4.3 实现抽象方法
创建IProductService接口，并在接口中添加findHotList()方法。
package com.cy.store.service.impl;import com.cy.store.entity.Product;
import com.cy.store.mapper.ProductMapper;
import com.cy.store.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;/** 处理商品数据的业务层实现类 */
@Service
public class ProductServiceImpl implements IProductService {@Autowiredprivate ProductMapper productMapper;@Overridepublic List<Product> findHotList() {List<Product> list = productMapper.findHotList();for (Product product : list) {product.setPriority(null);product.setCreatedUser(null);product.setCreatedTime(null);product.setModifiedUser(null);product.setModifiedTime(null);}return list;}
}
ProductServiceImpl–findHotList
5.商品热销排行–控制器
5.1 处理异常
说明：无异常
5.2 设计请求
1.设计用户提交的请求，并设计响应的方法
请求路径：/products/hot_list
请求参数：无
请求类型： GET
响应结果：JsonResult<List<Product>>
是否拦截：否，需要将index.html和/products/**请求添加白名单
2.在LoginInterceptorConfigurer中将index.html页面和/products/**请求添加白名单
patterns.add("/web/index.html");patterns.add("/products/**");LoginInterceptorConfigurer–/products
5.3 处理请求
1.创建ProductController类继承BaseController类，类添加@RestController和@RequestMapping(“products”)注解，并在类中添加业务层对象。
2.在类中添加处理请求的getHotList()方法。
package com.cy.store.controller;import com.cy.store.entity.Product;
import com.cy.store.service.IProductService;
import com.cy.store.util.JsonResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.List;@RestController
@RequestMapping("products")
public class ProductController extends BaseController {@Autowiredprivate IProductService productService;@RequestMapping("hot_list")public JsonResult<List<Product>> getHotList() {List<Product> data = productService.findHotList();return new JsonResult<List<Product>>(OK, data);}
}
ProductController–getHotList
3.完成后启动项目，直接访问测试。
6 商品热销排行–前端页面
1.在index.html给“热销排行”列表的div标签设置id属性值。
<div id="hot-list" class="panel-body panel-item">2.在index.html页面中body标签内部的最后，添加展示热销排行商品的代码。
<!-- showHotList --><script type="text/javascript">$(document).ready(function() {showHotList();});function showHotList() {$("#hot-list").empty();$.ajax({url: "/products/hot_list",type: "GET",dataType: "JSON",success: function(json) {let list = json.data;console.log("count=" + list.length);for (let i = 0; i < list.length; i++) {console.log(list[i].title);let html = '<div class="col-md-12">'+ '<div class="col-md-7 text-row-2"><a href="product.html?id=#{id}">#{title}</a></div>'+ '<div class="col-md-2">¥#{price}</div>'+ '<div class="col-md-3"><img src="..#{image}collect.png" class="img-responsive" /></div>'+ '</div>';html = html.replace(/#{id}/g, list[i].id);html = html.replace(/#{title}/g, list[i].title);html = html.replace(/#{price}/g, list[i].price);html = html.replace(/#{image}/g, list[i].image);$("#hot-list").append(html);}}});}</script><!-- showHotList -->
index.html–showHotList
最后测试
说明：图片存储在portal下
