Add these annotations on the startup class
automatic generator
(1) Create a new generator package and build the MybatisPlusGenerator class
create a directory

generate code
We're missing something after we generate
Now that our series of work is ready, we can upload the code
came in
3. Front-end construction
1. Templates add related interface
<!DOCTYPE html>
<html lang="zh">
<head>
<#include "common/head.ftl"/>
<style>
.layui-panel {
position: absolute;
width: 400px;

left: 50%;
transform: translate(-50%, -50%);
padding: 15px 15px 0px 15px;
border-radius: 20px;
}
.layui-form-label {
padding: 9px 0px;
}
h3 {
text-align: center;
line-height: 45px;
font-size: 40px;

<#include "../common/head.ftl">
</head>
<body>
<h1>这是商品展示界面</h1>
</body>
</html>import layui
Create a new project directory under resources->static->asset->js
①. Create a new JavaScript file named login
layui.use(["jquery","layer"],()=>{
//得到layuo中封装的jQuery
let $=layui.jquery
let layer=layui.layer
//给登录按钮设置事件
$(login).click(()=>{
console.log("login....")
//取表单的值
let mobile=$("#mobile").val()
let password=$("#password").val()
//前端加密的盐
let salt = "f1g2h3j4";
if(password){
//将密码和盐混一起
password=salt.charAt(1) + "" + salt.charAt(5) + password + salt.charAt(0) + "" + salt.charAt(3);
//进行md5加密
password=md5(password)
}
console.log(password)
//将数据给后台（前端分离axios 普通开发ajax）
$.ajax({
url: "/user/login",//后台登录接口
data:{ //需要携带的数据
mobile,
password
},
dataType:"json",//后台给你的数据类型
success(e){//成功的回调函数
layer.msg(e.message,{icon:6})
},
error(e){//报错的回调函数
},
})
})
}
)Create a new PathController class (under the controller package)
(1) Specially used for jumping paths: PathController class
package com.hmf.seckill.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class PathController {
//跳首页
@RequestMapping("/")
public String toPath(){
return "login";
}
//跳二级页面
@RequestMapping("/{dir}/{path}")
public String toPath(@PathVariable("dir") String dir,@PathVariable("path") String path){
//处理操作
return dir+"/"+path;
}
}
It's not good to provide all the source code because there are too many
so I just provide some important
4. MD5 encryption
1. Import help package and exception package
2. Passing values from the front and back ends
Create a new vo package and build a uservo class
package com.hmf.seckill.vo;
import com.hmf.seckill.util.response.ResponseResultCode;
import com.hmf.seckill.util.validate.IsMobile;
import com.hmf.seckill.util.validate.IsRequired;
import lombok.Data;
import org.aspectj.apache.bcel.classfile.Code;
import javax.validation.constraints.NotEmpty;
@Data
public class UserVo {
private String mobile;
private String password;
}
3. Login method:
①, IUserService interface
package com.hmf.seckill.service;
import com.hmf.seckill.pojo.User;
import com.baomidou.mybatisplus.extension.service.IService;
import com.hmf.seckill.util.response.ResponseResult;
import com.hmf.seckill.vo.UserVo;
/**
* <p>
* 用户信息表 服务类
* </p>
*
* @author hmf-git
* @since 2022-03-15
*/
public interface IUserService extends IService<User> {
ResponseResult<?> findByAccount(UserVo userVo);
}
②, implement the interface UserServiceImpl
package com.hmf.seckill.service.impl;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.hmf.seckill.exception.BusinessException;
import com.hmf.seckill.pojo.User;
import com.hmf.seckill.mapper.UserMapper;
import com.hmf.seckill.service.IUserService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.hmf.seckill.util.MD5Utils;
import com.hmf.seckill.util.ValidatorUtils;
import com.hmf.seckill.util.response.ResponseResult;
import com.hmf.seckill.util.response.ResponseResultCode;
import com.hmf.seckill.vo.UserVo;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Service;
import javax.swing.text.BadLocationException;
/**
* <p>
* 用户信息表 服务实现类
* </p>
*
* @author hmf-git
* @since 2022-03-15
*/
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService {
@Override
public ResponseResult<?> findByAccount(UserVo userVo) {
//先判断信息是否符合
if(!ValidatorUtils.isMobile(userVo.getMobile())){
throw new BusinessException(ResponseResultCode.USER_ACCOUNT_NOT_MOBLIE);
}
if(StringUtils.isBlank(userVo.getPassword())){
throw new BusinessException(ResponseResultCode.USER_ACCOUNT_NOT_MOBLIE);
}
//再看数据库查出对应的用户
User user=this.getOne(new QueryWrapper<User>().eq("id",userVo.getMobile()));
if(user==null){
throw new BusinessException(ResponseResultCode.USER_ACCOUNT_NOT_FIND);
}
//在比较密码
//二重加密
String salt=user.getSalt();
String newPassword=MD5Utils.formPassToDbPass(userVo.getPassword(),salt);
//将前台的加密和后端的盐再次加密
if(newPassword.equals(user.getPassword())){
throw new BusinessException(ResponseResultCode.USER_PASSWORD_NOT_MATCH);
}
return ResponseResult.success();
}
}
Controller layer
①、UserController
package com.hmf.seckill.controller;
import com.hmf.seckill.service.IUserService;
import com.hmf.seckill.util.response.ResponseResult;
import com.hmf.seckill.vo.UserVo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.validation.Valid;
/**
* <p>
* 用户信息表 前端控制器
* </p>
*
* @author hmf-git
* @since 2022-03-15
*/
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@RequestMapping("/login")
public ResponseResult<?> login(@Valid UserVo userVo){
//Call the login verification of service
System.out.println("aaaaaa");
return userService.findByAccount(userVo) ;
}
}
