九。后台管理系统
1.前面基本上的功能都已经实现了，最后就行优化和界面管理!
1)过滤器接口实现直接访问主页面的时候需要先登录的功能
在client里面创建filter创建UserFilter 类然后引入Filter重写方法
package com.redhat.filter;
import com.redhat.entity.User;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
@Component
@WebFilter(urlPatterns ={"/index.html"},filterName = "userFilter")
public class UserFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse)servletResponse;
HttpSession session = request.getSession();
User user = (User)session.getAttribute("user");
if (user==null){
response.sendRedirect("login.html");
}else{
filterChain.doFilter(servletRequest,servletResponse);
}
}
@Override
public void destroy() {
}
}
在client的启动类添加注解@ServletComponentScan
测试当输入index.html直接跳转到登录页面
2.添加admin的前端页面并实现相关操作和数据封装显示
1)前端页面main
链接：https://pan.baidu.com/s/1sN5ncNRDkFXH5Y3s3lWzlw
提取码：foq1
2)对应图片放在client的static里面
链接：https://pan.baidu.com/s/1AzLjsJUak7LzGjwAk6KBqA
提取码：k55q
3）修改clinet 的accounthandler下的完成剩下功能
case "admin":
Admin admin =new Admin();
idStr = hashMap.get("id")+"";
id = Long.parseLong(idStr);
String username2 = (String)hashMap.get("username");
admin.setId(id);
admin.setUsername(username2);
session.setAttribute("admin",admin);
result = "main";
break;
测试登录admin1管理员如下
修改路径测试
client前端页面main 中将<iframe src="/account/redirect/menu_manage"改为
<iframe src="/menu/redirect/menu_manage"
<!-- 主体开始 -->
<div class="layui-body">
<iframe src="/menu/redirect/menu_manage" style="width: 100%;height: 100%;border: 0px"></iframe>
</div>
client中userhandler主要将返回路径变成 return "redirect:/menu/redirect/menu_manage";
package com.redhat.controller;
import com.redhat.entity.User;
import com.redhat.entity.UserVO;
import com.redhat.feign.UserFeign;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import java.util.Date;
import java.util.List;
@Controller
@RequestMapping("/user")
public class UserHandler {
@Autowired
private UserFeign userFeign;
@GetMapping("/findAll")
@ResponseBody
public UserVO findAll(@RequestParam("page")int page, @RequestParam("limit")int limit){
int index = (page-1)*limit;
UserVO userVO = new UserVO();
userVO.setCode(0);
userVO.setMsg("");
userVO.setCount(userFeign.count());
userVO.setData(userFeign.findAll(index,limit));
return userVO;
}
// @GetMapping("/redirect/{location}")
// public String redirect(@PathVariable("location") String location){
// return location;
// }
@GetMapping("/count")
public int count(){
return userFeign.count();
}
@PostMapping("/save")
public String save(User user){
user.setRegisterdate(new Date());
userFeign.save(user);
return "redirect:/menu/redirect/user_manage";
}
@GetMapping("/deleteById/{id}")
public String deleteById(@PathVariable("id") long id) {
userFeign.deleteById(id);
return "redirect:/menu/redirect/user_manage";
}
}
结果测试
修改client，menuhandler实现编辑删除return "redirect:/menu/redirect/menu_manage";
package com.redhat.controller;
import com.redhat.entity.Menu;
import com.redhat.entity.MenuVO;
import com.redhat.feign.MenuFeign;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/menu")
public class MenuHandler {
@Autowired
private MenuFeign menuFeign;
@GetMapping("/findAll")
@ResponseBody
public MenuVO findAll(@RequestParam("page") int page, @RequestParam("limit") int limit
){
int index=(page-1)*limit;
return menuFeign.findAll(index,limit);
}
@GetMapping("/redirect/{location}")
public String redirect(@PathVariable("location") String location){
return location;
}
@GetMapping("/deleteById/{id}")
public String deleteById(@PathVariable("id") long id){
menuFeign.deleteById(id);
return "redirect:/menu/redirect/menu_manage";
}
@GetMapping("/findTypes")
public ModelAndView findTypes(){
ModelAndView modelAndView=new ModelAndView();
modelAndView.setViewName("menu_add");
modelAndView.addObject("list",menuFeign.findTypes());
return modelAndView;
}
@PostMapping("/save")
public String save(Menu menu){
menuFeign.save(menu);
return "redirect:/menu/redirect/menu_manage";
}
@GetMapping("/findById/{id}")
public ModelAndView findById(@PathVariable("id") long id){
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("menu_update");
modelAndView.addObject("menu",menuFeign.findById(id));
modelAndView.addObject("list",menuFeign.findTypes());
return modelAndView;
}
@PostMapping("/update")
public String update(Menu menu){
menuFeign.update(menu);
return "redirect:/menu/redirect/menu_manage";
}
}
1）修改
2）删除
2.增加添加菜品的页面
mian页面中页面改为对应编写的页面跳转即可
$("#menu_add").click(function(){
$("iframe").attr("src","/menu/findTypes");
});
将main里面的都写成menu跳转对象因为我们写的时候在menu里面可以直接跳转
<script type="text/javascript">
$(function () {
$("#menu_manage").click(function(){
$("iframe").attr("src","/account/redirect/menu_manage");
});
$("#menu_add").click(function(){
$("iframe").attr("src","/menu/findTypes");
});
$("#order_handler").click(function(){
$("iframe").attr("src","/menu/redirect/order_handler");
});
$("#user_manage").click(function(){
$("iframe").attr("src","/menu/redirect/user_manage");
});
$("#user_add").click(function(){
$("iframe").attr("src","/menu/redirect/user_add");
});
})
测试查询用户
测试添加用户
添加成功
3.加一个后台管理器的过滤器
没有加之前直接访问会出现
clinet模块下filter文件夹中 创建AdminFilter
package com.redhat.filter;
import com.redhat.entity.Admin;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
@Component
@WebFilter(urlPatterns = {"/main.html"},filterName = "adminFilter")
public class AdminFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse)servletResponse;
HttpSession session = request.getSession();
Admin admin = (Admin)session.getAttribute("admin");
if (admin==null){
response.sendRedirect("login.html");
}else{
filterChain.doFilter(servletRequest,servletResponse);
}
}
@Override
public void destroy() {
}
}
添加完成后直接跳转页面到登录
3.最后增加一个订单处理功能！
1)order模块下OrderRepository接口增加查找，统计，更新处理订单的方法接口
package com.redhat.repository;
import com.redhat.entity.Order;
import java.util.List;
public interface OrderRepository {
public void save(Order order);
public List<Order> findAllByUid(int index,int limit,long uid);
public int countByUid(long uid);
public List<Order> findAll(int index,int limit);
public void updateState(long id);
public int count();
}
2）order模块下OrderHandler类增加查找，更新处理订单的方法访问路径已经设置数据
@GetMapping("/findAll/{index}/{limit}")
public OrderVO findAll(@PathVariable("index") int index,@PathVariable("limit") int limit){
OrderVO orderVO = new OrderVO();
orderVO.setMsg("");
orderVO.setCount(orderRepository.count());
orderVO.setData(orderRepository.findAll(index,limit));
return orderVO;
}
@PutMapping("/update/{id}")
public void update(@PathVariable("id")long id){
orderRepository.updateState(id);
}
3）order模块下mapping orderrepository.xml中加入需要的对应三个sql语句
<select id="findAll" resultMap="orderMap">
select id,mid,date,state from t_order where state = 0 limit #{param1},#{param2}
</select>
<select id="updateState" parameterType="long">
update t_order set state = 1 where id = #{id}
</select>
<select id="count" resultType="int">
select count(*) from t_order where state=0
</select>
测试查找功能
postman中测试更新功能
更新状态前
执行更新
更新成功
4.全部测通以后最后一步就是在client中使用这两个接口方法
1）添加order的前端页面这些前端代码都是官网找的，加到client的static中进行存储备用，接口测试方法可以了以后直接调用页面就行了
链接：https://pan.baidu.com/s/1T3ywYAPdBa1yijRolCYGSg
提取码：p9wd
2）对应前端需要对应的数据进行查询
order模块下mapping orderrepository.xml中加入需要的对应三个sql语句
还需要加uid
<select id="findAll" resultMap="orderMap">
select id,mid,uid,date,state from t_order where state = 0 limit #{param1},#{param2}
</select>
这里得加上user的信息查询 <association property="user" select="com.redhat.repository.UserRepository.findById" column="uid"></association>
<resultMap id="orderMap" type="com.redhat.entity.Order">
<id column="id" property="id"></id>
<result column="date" property="date"></result>
<result column="state" property="state"></result>
<association property="menu" select="com.redhat.repository.MenuRepository.findById" column="mid"></association>
<association property="user" select="com.redhat.repository.UserRepository.findById" column="uid"></association>
</resultMap>
3）复制对应的user接口到client模块下和sql语句只留findById
package com.redhat.repository;
import com.redhat.entity.User;
import java.util.List;
public interface UserRepository {
public User findById(long id);
}
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.redhat.repository.UserRepository">
<select id="findById" parameterType="long" resultType="com.redhat.entity.User">
select * from t_user where id = #{id}
</select>
</mapper>
其余client的接口和sql语句也只留需要的即可
测试
最后调用页面
client中的OrderFeign注意对比修改
package com.redhat.feign;
import com.redhat.entity.MenuVO;
import com.redhat.entity.Order;
import com.redhat.entity.OrderVO;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.*;
@FeignClient(value = "order")
public interface OrderFeign {
@PostMapping("/order/save")
public void save(@RequestBody Order order);
@GetMapping("/order/findAllByUid/{index}/{limit}/{uid}")
public OrderVO findAllByUid(@PathVariable("index") int index,
@PathVariable("limit") int limit,
@PathVariable("uid") long uid
);
@GetMapping("/order/findAll/{index}/{limit}")
public OrderVO findAll(@PathVariable("index")int index,@PathVariable("limit")int limit);
@GetMapping("/order/updateState/{id}")
public void updateState(@PathVariable("id") long id);
}
Order模块下的OrderHandler需要修改如下
@GetMapping("/updateState/{id}")
public void updateState(@PathVariable("id")long id){
orderRepository.updateState(id);
}
}
Client模块下的OrderHandler需要修改如下
@GetMapping("/updateState/{id}")
public String updateState(@PathVariable("id") long id){
orderFeign.updateState(id);
return "redirect:/menu/redirect/order_handler";
}
最后前端页面修改
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" th:href="@{/layui/css/layui.css}" media="all">
</head>
<body class="layui-layout-body">
<div class="layui-container" style="margin-top: 50px;width: 750px;width: 1070px">
<table class="layui-hide" id="test" style="width: 300px" lay-filter="test"></table>
<script type="text/html" id="barDemo">
<a class="layui-btn layui-btn-xs" lay-event="send">已派送</a>
</script>
<script th:src="@{/layui/layui.js}" charset="utf-8"></script>
<script>
layui.use('table', function(){
var table = layui.table;
table.render({
elem: '#test'
,url:'/order/findAll'
,title: '订单列表'
,cols: [
[
{field:'id', width:80, title: '编号', sort: true}
, {
field: 'name', width: 160, title: '菜品', templet: function (data) {
return data.menu.name
}
}
, {
field: 'price', width: 80, title: '单价', templet: function (data) {
return data.menu.price
}
}
,{field:'flavor', width:80, title: '口味',templet:function(data){
return data.menu.flavor
}
}
,{field:'nickname', width:80, title: '用户',templet:function(data){
return data.user.nickname
}
}
,{field:'telephone', width:140, title: '联系电话',templet:function(data){
return data.user.telephone
}
}
,{field:'address', width:140, title: '地址',templet:function(data){
return data.user.address
}
}
,{field:'date',width:220, title: '下单时间'}
,{fixed: 'right', title:'操作', toolbar: '#barDemo', width:90}
]
]
,page: true
});
//监听行工具事件
table.on('tool(test)', function(obj){
var data = obj.data;
if(obj.event === 'send'){
window.location.href="/order/updateState/"+data.id;
}
});
});
</script>
</div>
<script>
//二级菜单联动
layui.use('element', function(){
var element = layui.element;
});
</script>
</body>
</html>
最后登录更改状态测试
查找出未派送
操作【已派送】
数据库结果
登录张三客户端查看
到此所有的系统整合完成！修整一下进行下面的一个实战项目的学习。希望大家一起学习进步，如果有那些地方没有写对的希望大家批判指正，我边学习边记下自己的流程和相关理解知识，希望大家一起进步！
