}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);
