vue2+element-ui+springboot+mybatis-plus获取当前账户进行修改密码详细教程-526互联

以下内容仅供学习使用

新建一个dto类，用于专门修改当前账户的使用

import lombok.Data;

@Data
public class UserPasswordDTO {
    private String username;
    private String phone;
    private String password;
    private String newPassword;
}

编写controller类,下面的示例代码进行了md5加密处理

 /**
     * 修改密码
     *
     * @param userPasswordDTO
     * @return
     */
    @PostMapping("/password")
    public Result password(@RequestBody UserPasswordDTO userPasswordDTO) {
        userPasswordDTO.setPassword(SecureUtil.md5(userPasswordDTO.getPassword()));
        userPasswordDTO.setNewPassword(SecureUtil.md5(userPasswordDTO.getNewPassword()));
        userService.updatePassword(userPasswordDTO);
        return Result.success();
    }

IUserService

import com.el.springboot.controller.dto.UserPasswordDTO;
import com.el.springboot.entity.User;
import com.baomidou.mybatisplus.extension.service.IService;

/**
 * <p>
 *  服务类
 * </p>
 *
 * @author el
 * @since 2023-03-19
 */
public interface IUserService extends IService<User> {
    void updatePassword(UserPasswordDTO userPasswordDTO);
}

实现类

 /**
     * 修改密码加密
     * @param userPasswordDTO
     */
    @Override
    public void updatePassword(UserPasswordDTO userPasswordDTO) {
        int update = userMapper.updatePassword(userPasswordDTO);
        if (update < 1) {
            throw new ServiceException(Constants.CODE_600, "密码错误");
        }
    }

mapper类

   @Update("update sys_user set password = #{newPassword} where username = #{username} and password = #{password}")
    int updatePassword(UserPasswordDTO userPasswordDTO);

页面代码

<template>
  <el-card style="width: 500px;">
    <el-form label-width="120px" size="small" :model="form" :rules="rules" ref="pass">
      <el-form-item label="原密码" prop="password">
        <el-input v-model="form.password" autocomplete="off" show-password></el-input>
      </el-form-item>
      <el-form-item label="新密码" prop="newPassword">

      </el-form-item>
      <el-form-item label="确认新密码" prop="confirmPassword">
