路由类
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
<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
<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);
