瑞吉外卖笔记（瑞吉外卖ppt）

1.数据库环境搭建

创建数据库

create database reggie character set utf8mb4;

执行sql命令,注意该脚本不要放在中文目录中。

mysql > source D:/db_reggie.sql

2.maven项目创建

注意检查项目编码，jdk配置，maven配置。

3.定义pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4.定义springboot配置文件application.yml

server:
  port: 8080
spring:
  application:
    #应用的名称，可选
    name: reggie_take_out
  datasource:
    druid:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/xuetoucloud?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
      username: root
      password: caicai123
      max-active: 100
      initial-size: 1
      max-wait: 60000
      min-idle: 1
      time-between-eviction-runs-millis: 60000
      min-evictable-idle-time-millis: 300000
      validation-query: select 'x'
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      pool-prepared-statements: true
      max-open-prepared-statements: 50
      max-pool-prepared-statement-per-connection-size: 20
mybatis-plus:
  mapper-locations: classpath:/mapper/**.xml
  configuration:
    #在映射实体或者属性时，将数据库中表名和字段名中的下划线去掉，按照驼峰命名法映射
    map-underscore-to-camel-case: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
  global-config:
    db-config:
      id-type: ASSIGN_ID
reggie:
  path: D:\img\

5.启动类

package com.itheima.reggie;

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Slf4j
//@SpringBootApplication(scanBasePackages={"com.itheima.reggie"})
@SpringBootApplication
@ServletComponentScan
@EnableTransactionManagement

public class ReggieApplication {
    public static void main(String[] args) {
        SpringApplication.run(ReggieApplication.class,args);
        log.info("项目启动成功...");
    }
}

6.配置静态资源映射，访问html、js、css等静态文件。

在config包添加配置

package com.itheima.reggie.config;

import com.itheima.reggie.common.JacksonObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

import java.util.List;

@Slf4j
@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {
    /**
     * 设置静态资源映射
     * @param registry
     */
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        log.info("开始进行静态资源映射...");
        registry.addResourceHandler("/backend/**").addResourceLocations("classpath:/backend/");
        registry.addResourceHandler("/front/**").addResourceLocations("classpath:/front/");
    }
    /**
     * 扩展mvc框架的消息转换器
     * @param converters
     */
    @Override
    protected void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
        log.info("扩展消息转换器...");
        //创建消息转换器对象
        MappingJackson2HttpMessageConverter messageConverter = new MappingJackson2HttpMessageConverter();
        //设置对象转换器，底层使用Jackson将Java对象转为json
        messageConverter.setObjectMapper(new JacksonObjectMapper());
        //将上面的消息转换器对象追加到mvc框架的转换器集合中
        converters.add(0,messageConverter);
    }

}

7.开发登陆功能

package com.itheima.reggie.controller;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.itheima.reggie.common.R;
import com.itheima.reggie.entity.Employee;
import com.itheima.reggie.service.EmployeeService;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.DigestUtils;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.HttpServletRequest;
import java.time.LocalDateTime;

@Slf4j
@RestController
@RequestMapping("/employee")
public class EmployeeController {

    @Autowired
    private EmployeeService employeeService;

    /**
     * 员工登录
     * @param request
     * @param employee
     * @return
     */
    @PostMapping("/login")
    public R<Employee> login(HttpServletRequest request,@RequestBody Employee employee){

        //1、将页面提交的密码password进行md5加密处理
        String password = employee.getPassword();
        password = DigestUtils.md5DigestAsHex(password.getBytes());

        //2、根据页面提交的用户名username查询数据库
        LambdaQueryWrapper<Employee> queryWrapper = new LambdaQueryWrapper<>();
        queryWrapper.eq(Employee::getUsername,employee.getUsername());
        Employee emp = employeeService.getOne(queryWrapper);

        //3、如果没有查询到则返回登录失败结果
        if(emp == null){
            return R.error("登录失败");
        }

        //4、密码比对，如果不一致则返回登录失败结果
        if(!emp.getPassword().equals(password)){
            return R.error("登录失败");
        }

        //5、查看员工状态，如果为已禁用状态，则返回员工已禁用结果
        if(emp.getStatus() == 0){
            return R.error("账号已禁用");
        }

        //6、登录成功，将员工id存入Session并返回登录成功结果
        request.getSession().setAttribute("employee",emp.getId());
        return R.success(emp);
    }

    /**
     * 员工退出
     * @param request
     * @return
     */
    @PostMapping("/logout")
    public R<String> logout(HttpServletRequest request){
        //清理Session中保存的当前登录员工的id
        request.getSession().removeAttribute("employee");
        return R.success("退出成功");
    }

  <script>
    new Vue({
      el: '#login-app',
      data() {
        return {
          loginForm:{
            username: 'admin',
            password: '123456'
          },
          loading: false
        }
      },
      computed: {
        loginRules() {
          const validateUsername = (rule, value, callback) => {
            if (value.length < 1 ) {
              callback(new Error('请输入用户名'))
            } else {
              callback()
            }
          }
          const validatePassword = (rule, value, callback) => {
            if (value.length < 6) {
              callback(new Error('密码必须在6位以上'))
            } else {
              callback()
            }
          }
          return {
            'username': [{ 'validator': validateUsername, 'trigger': 'blur' }],
            'password': [{ 'validator': validatePassword, 'trigger': 'blur' }]
          }
        }
      },
      created() {
      },
      methods: {
        async handleLogin() {
          this.$refs.loginForm.validate(async (valid) => {
            if (valid) {
              this.loading = true
              let res = await loginApi(this.loginForm)
              if (String(res.code) === '1') {//1表示登录成功
                localStorage.setItem('userInfo',JSON.stringify(res.data))
                window.location.href= '/backend/index.html'
              } else {
                this.$message.error(res.msg)
                this.loading = false
              }
            }
          })
        }
      }
    })
  </script>
</body>

</html>

function loginApi(data) {
  return $axios({
    'url': '/employee/login',
    'method': 'post',
    data
  })
}

function logoutApi(){
  return $axios({
    'url': '/employee/logout',
    'method': 'post',
  })
}

注意：localStorage在浏览器保存为json数据，表示用户已登录

localStorage.setItem('userInfo',JSON.stringify(res.data))

登陆成功之后做页面跳转

window.location.href= '/backend/index.html'

8.定义员工表实体类，用来和数据库映射

package com.itheima.reggie.entity;

import com.baomidou.mybatisplus.annotation.FieldFill;
import com.baomidou.mybatisplus.annotation.TableField;
import lombok.Data;
import java.io.Serializable;
import java.time.LocalDateTime;

/**
 * 员工实体
 */
@Data
public class Employee implements Serializable {

    private static final long serialVersionUID = 1L;

    private Long id;

    private String username;

    private String name;

    private String password;

    private String phone;

    private String sex;

    private String idNumber;//身份证号码

    private Integer status;


    @TableField(fill = FieldFill.INSERT) //插入时填充字段
    private LocalDateTime createTime;

    @TableField(fill = FieldFill.INSERT_UPDATE) //插入和更新时填充字段
    private LocalDateTime updateTime;

    @TableField(fill = FieldFill.INSERT) //插入时填充字段
    private Long createUser;

    @TableField(fill = FieldFill.INSERT_UPDATE) //插入和更新时填充字段
    private Long updateUser;

}

9.登陆代码开发，Controller,Service,Mapper

Controller

package com.itheima.reggie.controller;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.itheima.reggie.common.R;
import com.itheima.reggie.entity.Employee;
import com.itheima.reggie.service.EmployeeService;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.DigestUtils;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.HttpServletRequest;
import java.time.LocalDateTime;

@Slf4j
@RestController
@RequestMapping("/employee")
public class EmployeeController {

    @Autowired
    private EmployeeService employeeService;

    /**
     * 员工登录
     * @param request
     * @param employee
     * @return
     */
    @PostMapping("/login")
    public R<Employee> login(HttpServletRequest request,@RequestBody Employee employee){

        //1、将页面提交的密码password进行md5加密处理
        String password = employee.getPassword();
        password = DigestUtils.md5DigestAsHex(password.getBytes());

        //2、根据页面提交的用户名username查询数据库
        LambdaQueryWrapper<Employee> queryWrapper = new LambdaQueryWrapper<>();
        queryWrapper.eq(Employee::getUsername,employee.getUsername());
        Employee emp = employeeService.getOne(queryWrapper);

        //3、如果没有查询到则返回登录失败结果
        if(emp == null){
            return R.error("登录失败");
        }

        //4、密码比对，如果不一致则返回登录失败结果
        if(!emp.getPassword().equals(password)){
            return R.error("登录失败");
        }

        //5、查看员工状态，如果为已禁用状态，则返回员工已禁用结果
        if(emp.getStatus() == 0){
            return R.error("账号已禁用");
        }

        //6、登录成功，将员工id存入Session并返回登录成功结果
        request.getSession().setAttribute("employee",emp.getId());
        return R.success(emp);
    }

    /**
     * 员工退出
     * @param request
     * @return
     */
    @PostMapping("/logout")
    public R<String> logout(HttpServletRequest request){
        //清理Session中保存的当前登录员工的id
        request.getSession().removeAttribute("employee");
        return R.success("退出成功");
    }


    /**
     * 新增员工
     * @param employee
     * @return
     */
    @PostMapping
    public R<String> save(HttpServletRequest request,@RequestBody Employee employee){
        log.info("新增员工，员工信息：{}",employee.toString());

        //设置初始密码123456，需要进行md5加密处理
        employee.setPassword(DigestUtils.md5DigestAsHex("123456".getBytes()));

//        employee.setCreateTime(LocalDateTime.now());
//        employee.setUpdateTime(LocalDateTime.now());
//
//        //获得当前登录用户的id
//        Long empId = (Long) request.getSession().getAttribute("employee");

//        employee.setCreateUser(empId);
//        employee.setUpdateUser(empId);

        employeeService.save(employee);

        return R.success("新增员工成功");
    }

    /**
     * 员工信息分页查询
     * @param page
     * @param pageSize
     * @param name
     * @return
     */
    @GetMapping("/page")
    public R<Page> page(int page, int pageSize, String name){
        log.info("page = {},pageSize = {},name = {}" ,page,pageSize,name);
        Long id = Thread.currentThread().getId();
        log.info("线程ID{}",id);
        //构造分页构造器
        Page pageInfo = new Page(page,pageSize);

        //构造条件构造器
        LambdaQueryWrapper<Employee> queryWrapper = new LambdaQueryWrapper();
        //添加过滤条件
        queryWrapper.like(StringUtils.isNotEmpty(name),Employee::getName,name);
        //添加排序条件

Service

package com.itheima.reggie.service;

import com.baomidou.mybatisplus.extension.service.IService;
import com.itheima.reggie.entity.Employee;

public interface EmployeeService extends IService<Employee> {
}

EmployeeServiceImpl

package com.itheima.reggie.service.impl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.itheima.reggie.entity.Employee;
import com.itheima.reggie.mapper.EmployeeMapper;
import com.itheima.reggie.service.EmployeeService;
import org.springframework.stereotype.Service;

@Service
public class EmployeeServiceImpl extends ServiceImpl<EmployeeMapper,Employee> implements EmployeeService{
}

10.通用返回结果类

使用方式举例，

返回成功结果，return R.success(employee);

返回失败信息，return R.error("没有查询到对应员工信息");

定义编码code，1表示成功，0和其它数字为失败

package com.itheima.reggie.common;

import lombok.Data;
import java.util.HashMap;
import java.util.Map;

/**
 * 通用返回结果，服务端响应的数据最终都会封装成此对象
 * @param <T>
 */
@Data
public class R<T> {

    private Integer code; //编码：1成功，0和其它数字为失败

    private String msg; //错误信息

    private T data; //数据

    private Map map = new HashMap(); //动态数据

    public static <T> R<T> success(T object) {
        R<T> r = new R<T>();
        r.data = object;
        r.code = 1;
        return r;
    }

    public static <T> R<T> error(String msg) {
        R r = new R();
        r.msg = msg;
        r.code = 0;
        return r;
    }

    public R<T> add(String key, Object value) {
        this.map.put(key, value);
        return this;
    }

}

@PostMapping("/login")
public R<Employee> login(HttpServletRequest request,@RequestBody Employee employee){

post请求传递json数据，请加注解@RequestBody

//6、登录成功，将员工id存入Session并返回登录成功结果
request.getSession().setAttribute("employee",emp.getId());
return R.success(emp);

11.员工退出

/**
 * 员工退出
 * @param request
 * @return
 */
@PostMapping("/logout")
public R<String> logout(HttpServletRequest request){
    //清理Session中保存的当前登录员工的id
    request.getSession().removeAttribute("employee");
    return R.success("退出成功");
}

12.首页

    <el-menu-item
      v-for="sub in item.children"
      :index="sub.id"
      :key="sub.id"
      @click="menuHandle(sub,false)"
      >
      <i :class="iconfont" :class="sub.icon"></i>
      <span slot="title">{{sub.name}}</span>
      </el-menu-item
    >
  </el-submenu>
  <el-menu-item v-else :index="item.id" @click="menuHandle(item,false)">
    <i class="iconfont" :class="item.icon"></i>
    <span slot="title">{{item.name}}</span>
  </el-menu-item>
</div>

菜单单击事件

menuHandle(item, goBackFlag) {
  this.loading = true
  this.menuActived = item.id
  this.iframeUrl = item.url
  this.headTitle = item.name
  this.goBackFlag = goBackFlag
  this.closeLoading()
}

iframe显示网页
