编写配置文件 application.yml

将数据库相关实体类复制到pojo包

在controller包编写PageController类，用于跳转到Thymeleaf页面, 能跳转到前台页面也可以跳转到后台页面

package com.hgy.travel.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * TODO 类描述
 *
 * @author HGY
 * @date 2023/5/10 20:01
 */
@Controller
public class PageController {

   //访问后台页面
   @RequestMapping("/backstage/{page}")
   public String showPageBackstage(@PathVariable String page){
      return "/backstage/" + page;
   }

   //访问前台页面
   @RequestMapping("/frontdesk/{page}")
   public String showPageFrontdesk(@PathVariable String page){
      return "/frontdesk/" + page;
   }

   //忽略访问项目logo 可以写也可以不写
   @RequestMapping("favicon.ico")
   @ResponseBody
   void returnNoFavicon(){}

}

在templates下编写前台和后台文件夹然后再backstage下创建一个demo.html然后启动项目进行测试

项目搭建_AdminLTE

官网:

项目分为管理员端和用户端。管理员端负责管理网站资源，发布旅游产品；用户端可以查询旅游产品，收藏旅游产品等。两端使用的页面风格不同。在项目中，我们使用AdminLTE框架作为管理员端页面，使用自己编写的网页作为用户端页面。

AdminLTE是一款建立在bootstrap和jquery之上的开源的模板主题工具，它提供了一系列响应的、可重复使用的组件，并内置了多个模板页面；同时自适应多种屏幕分辨率，兼容PC和移动端。通过AdminLTE，我们可以快速的创建一个响应式的Html5网站。AdminLTE框架在网页架构与设计上，有很大的辅助作用，尤其是前端架构设计师，用好AdminLTE 不但美观，而且可以免去写很大CSS与JS的工作量。

使用AdminLTE非常简单，只需要根据需求将需要的组件复制到我们的页面中即可。

将dist中的静态资源复制到/static/backstage中。

编写后台首页

使用AdminLTE的模板页面编写后台首页index.html

提取统一后台模板

把头、菜单、footer、重复引入的资源等提取到一个模板.

提取完的index

后台用户管理_管理员列表

后台用户也称为管理员，每个管理员能在后台进行的操作不同，所以不同的管理员有不同的权限。在项目中，权限表的设计为用户—角色多对多，角色—权限多对多，既一个用户有多个角色，一个角色有多个权限。所以后台首先要拥有用户管理、角色管理、权限管理的功能。

我们首先编写用户管理中的查询用户功能。

编写AdminMapper

编写AdminService

在启动类扫描mapper接口，注册mybatis-plus分页插件

编写AdminController

管理员列表_前端页面

编写页面admin_all.html
