Controller

代码语言:javascript复制
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
代码语言:javascript复制
select * from tb_shop_category a where a.parent_id is null ;
代码语言:javascript复制
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

代码语言:javascript复制
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

代码语言:javascript复制
<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

代码语言:javascript复制
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);
