index.js

index.css

.index-banner {height: 35%;padding-bottom: 0.4rem; } .img-wrap {overflow: hidden; } .banner-img {width: 100%;height: 100%; } .total-shop-button {height: 1.5rem;line-height: 1.5rem;padding-left: 0.85rem;margin-bottom: 0.4rem;position: relative;cursor: pointer; } .total-shop-button:before {content: '';display: inline-block;position: absolute;left: 0;width: 0.15rem;height: 1.5rem;background-color: #0894ec; } .shop-classify {height: 3.3rem;padding: 0.2rem;cursor: pointer; } .shop-classify > .word {width: 65%;height: 100%;overflow: hidden;float: left; } .shop-classify > .word > p {margin: 0; } .shop-classify > .word > .shop-title {margin: 0;font-size: 0.8rem; } .shop-classify > .word > .shop-desc {margin: 0;font-size: 0.4rem; } // .shop-classify > .shop-img { // width: 2.4rem; // height: 2.4rem; // margin-left: 0.2rem; // display: inline-block; // } .shop-classify > .shop-classify-img-warp {width: 30%;height: 100%;margin-left: 0.2rem;display: inline-block; } .shop-classify > .shop-classify-img-warp > .shop-img {width: 100%;height: 100%; }

Controller

package com.artisan.o2o.web.frontend;import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod;@Controller @RequestMapping("/frontend") public class FrontEndController {@RequestMapping(value = "/index" ,method = RequestMethod.GET)public String index(){return "frontend/index";} }

调测

启动tomcat，根据路由规则，访问 http://localhost:8080/o2o/frontend/index

修复问题

页面雏形OK，从后台获取的数据也基本没有问题，但是图片没有显示，原因有2个

  • 图片地址不对
  • 前端解析映射的图片有问题

逐条来分析原因

我们先看下库表中的数据 ，涉及到的表

  • 头条信息 tb_head_line，
  • 商铺类别 tb_shop_category
select * from tb_shop_category a where a.parent_id is null ;

select * from tb_head_line a where a.enable_status = 1;

模拟数据，我们先将数据修复为正确的数据。 因为我们还没有做头条信息和商铺类别的管理页面，我们这里先按照设计插入符合预期的数据信息。

头条图片展示修复

更新后的数据如下

确保在本地磁盘上有这些对应名称的头条信息

脚本如下

INSERT INTO `tb_head_line` VALUES (6, '购物', 'xxx', '\\upload\\item\\headtitle\\2018072520315746624.jpg', 99, 1, NULL, NULL); INSERT INTO `tb_head_line` VALUES (2, '家具', 'x', '\\upload\\item\\headtitle\\2018072520371786788.jpg', 98, 1, NULL, NULL); INSERT INTO `tb_head_line` VALUES (3, '健身', 'xx', '\\upload\\item\\headtitle\\2018072520393452772.jpg', 97, 1, NULL, NULL); INSERT INTO `tb_head_line` VALUES (4, '美容', 'aa', '\\upload\\item\\headtitle\\2018072520400198256.jpg', 96, 1, NULL, NULL); commit;

配置映射路径

tomcat的server.xml中增加如下信息

<Context docBase="D:/o2o/image/upload" path="/upload"/>

重新部署工程，先remove，然后在发布

启动tomcat，重新访问 http://localhost:8080/o2o/frontend/index

头条信息展示正常。

一级类别商铺图片展示修复

同上，这里省略步骤

INSERT INTO `tb_shop_category` VALUES (1, '二手市场', '二手市场专区', '\\upload\\item\\shopcategory\\2018071523272255687.png', 9, '2018-7-27 16:32:50', '2018-7-27 16:32:50', NULL); INSERT INTO `tb_shop_category` VALUES (2, '美容美发', '美容美发专区', '\\upload\\item\\shopcategory\\2018071523273314635.png', 8, '2018-7-27 16:32:50', '2018-7-27 16:32:50', NULL); INSERT INTO `tb_shop_category` VALUES (3, '美食饮品', '美食饮品专区', '\\upload\\item\\shopcategory\\2018071523274213433.png', 7, '2018-7-27 16:32:50', '2018-7-27 16:32:50', NULL); INSERT INTO `tb_shop_category` VALUES (4, '休闲娱乐', '休闲娱乐专区', '\\upload\\item\\shopcategory\\2018071523275121460.png', 6, '2018-7-27 16:32:50', '2018-7-27 16:32:50', NULL); INSERT INTO `tb_shop_category` VALUES (5, '培训教育', '培训教育专区', '\\upload\\item\\shopcategory\\2018071523280082147.png', 5, '2018-7-27 16:32:50', '2018-7-27 16:32:50', NULL); INSERT INTO `tb_shop_category` VALUES (6, '租赁市场', '租赁市场专区', '\\upload\\item\\shopcategory\\2018071523281361578.png', 4, '2018-7-27 16:32:50', '2018-7-27 16:32:50', NULL);
