更新时间：2022年12月21日 09:04:02 作者：秋名山码民

这篇文章主要介绍了Java实现注册登录与邮箱发送账号验证激活功能，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习吧

前言

项目流程图如下：

这里我们通过：

163邮箱来实现激活码发送
qq邮箱来进行接收

学习之前需要掌握的知识

springboot的基本使用方法
mysql的使用
mybatis的简单使用

项目环境搭建

这里我们直接使用 Spring Initializr 初始化 Spring Boot 项目

环境依赖选择：

lombok简化开发，使用注解，避免写重复性代码
SpringWeb，实现一个前后端的数据交互（一个登录注册验证，没必要写前后端分离）
MySQL
MyBatis

application.yml配置

server:
port: 8001

spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/email?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false
username: root
password: qwer123.
mail:
protocol: smtp # 邮件协议
host: smtp.163.com # 网易邮箱 smtp 服务器地址
port: 25
username: mashengmingming@163.com # 发件人邮箱地址
password: # 授权码

数据库的搭建

基本字段：id，email，password 常用的拓展字段：

activation_time                   // 激活失效时间
confirm_code               // 确认代码
is_vaild                   // 是否可用 0-不可用 1-可用
salt                       // 加密盐
gmt_create                   // 创建时间
gmt_modified               // 修改时间

具体的建表语句

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`  (
  `id` bigint NOT NULL AUTO_INCREMENT COMMENT '主键\r\n',
  `email` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '邮箱',
  `password` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '密码',
  `activation_time` timestamp NULL DEFAULT NULL COMMENT '激活失效时间',
  `confirm_code` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '确认码',
  `is_vaild` int NULL DEFAULT NULL COMMENT '是否可用，0不可用，1可用',
  `salt` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '加密盐',
  `gmt_create` timestamp NULL DEFAULT NULL COMMENT '创建时间',
  `gmt_modified` timestamp NULL DEFAULT NULL COMMENT '更新时间',
  PRIMARY KEY (`id`) USING BTREE,
  UNIQUE INDEX `email`(`email` ASC) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 9 CHARACTER SET = utf8mb3 COLLATE = utf8mb3_general_ci ROW_FORMAT = Dynamic;
INSERT INTO `user` VALUES (8, '986438626@qq.com', '09eff3f9a0817674c4d79c01eb156092', '2022-12-20 17:08:09', '1604765517418205184', 1, 'bn1sqy', '2022-12-19 17:08:09', '2022-12-19 17:08:09');
SET FOREIGN_KEY_CHECKS = 1;

前端页面的搭建

前后端不分离下，我们前端页面一般放到templates下面

长这个样子：

后端代码

格式

典型的分层模型，

pojo

package com.expamle.emailloginregister.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
import java.time.LocalDateTime;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User implements Serializable {
        private Integer id; // 主键Id
        private String email; // 邮箱
        private String password; // 密码 md5+盐
       /* @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")*/
        private LocalDateTime activationTime; // 激活失效时间
        private String confirmCode; // 确认代码
        private Integer isVaild; // 是否可用 0-不可用 1-可用
        private String salt; // 加密盐
/*
        @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
*/
        private LocalDateTime gmtCreate; // 创建时间
/*
        @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
*/
        private LocalDateTime gmtModified; // 修改时间
}

mapper

主要通过mybatis来写一些与user相关的sql语句

package com.expamle.emailloginregister.mapper;
import com.expamle.emailloginregister.pojo.User;
import org.apache.ibatis.annotations.*;
import java.util.List;
@Mapper
public interface UserMapper {
    /**
     * 注册插入用户信息
     * */
    @Insert("insert into user(email,password,activation_time,confirm_code,is_vaild,salt,gmt_create,gmt_modified)" +
            "values(#{email},#{password},#{activationTime},#{confirmCode},#{isVaild},#{salt},#{gmtCreate},#{gmtModified})")
    int insertUser(User user);
    /**
     * 根据confirm_code查询与用户是否已激活
     * confirm_code
     * is_vaild
     * */
    @Select("select email,activation_time from user where confirm_code = #{confirmCode} and is_vaild = 0")
    User findUserByConfirmCode(@Param("confirmCode") String confirmCode);
    /**
     * 根据激活码查询用户 并 修改状态值
     * */
    @Update("update user set is_vaild=1 where confirm_code = #{confirmCode}")
    int confirmUser(@Param("confirmCode") String confirmCode);
    /**
     * 根据邮箱查询账号
     * */
    @Select("select email,password,salt from user where email=#{email} and is_vaild=1")
    List<User> findUserByEmail(@Param("email") String email);
    /**
     * 用户查重
     * */
    @Select("select count(*) from user where email=#{email} limit 1")
    int emailExist(@Param("email") String email);
}

Controller

与前端页面进行交互，负责一个登录，注册数据的提交和响应

SystemController

package com.expamle.emailloginregister.controller;
import com.expamle.emailloginregister.pojo.User;
import com.expamle.emailloginregister.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
/**
*@Controller 不可使用RestControoler
*使用RestController要进行一个封装
*/
@Controller
public class SystemController {
    @Autowired
    private UserService userService;

    /**
     * 登录
     * */
    @GetMapping("/login")
    public String login(){

       return "login";
    }
    /**
     * 注册
     * */
    @GetMapping("/registry")
    public String registry(User user){
        return "registry";
    }
}

UserController

package com.expamle.emailloginregister.controller;
import com.expamle.emailloginregister.pojo.User;
import com.expamle.emailloginregister.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.Map;
@RestController
@RequestMapping("users")
public class UserController {
@Autowired
    private UserService userService;
    /**
     * 注册账号
     * */
    @PostMapping("register")
    public Map<String,Object> registery(User user){
      Map<String,Object> map  =  userService.createAccount(user);
        return map;
    }
    /**
     * 用户登录
     * */
    @PostMapping("login")
    public Map<String,Object> login(User user){
        Map<String,Object> map = userService.accountLogin(user);
        return map;
    }
    /**
     * 账号激活
     * 激活码附在请求后
     *
     * */
    @GetMapping("activation")
    public Map<String,Object> activationAccount(String confirmCode){
        Map<String,Object> map = userService.activationAccount(confirmCode);
        return map;
    }
}

service

先写俩个接口，在Impl中进行实现，

EmailServiceImpl

package com.expamle.emailloginregister.service;
public interface EmailService {
    void sendEmail(String email,String activationUrl);
}

实现sendEmail

package com.expamle.emailloginregister.service.Impl;
import com.expamle.emailloginregister.service.EmailService;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;
import javax.annotation.Resource;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.util.Date;
/**
 * 发送邮件相关业务
 * */
@Service
public class EmailServiceImpl implements EmailService {
    // 引入配置文件属性
    @Value("${spring.mail.username}")
    private String sendUsername;
    // javamain mail依赖方法---此方法无法使用autowird注入，javaMailSender不是springboot的方法
    @Resource
    private JavaMailSender javaMailSender;
    @Resource //同上
    private TemplateEngine templateEngine;
    public void sendEmail(String email,String activationUrl){
        // 创建邮件对象
        MimeMessage mimeMessage = javaMailSender.createMimeMessage();
        try {
            /**
             * MineMessagehelper---设置邮件相关内容
             * @Params1 邮件对象
             * @Params2 是否发送多封邮件
             * */
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage,true);
            // 设置邮件主题
            message.setSubject("注册账号激活");
            // 设置邮件发送者
            message.setFrom(sendUsername);
            // 设置邮件接收者，可多个
            message.setTo(email);
            // 设置邮件抄送人
           /* message.setCc();*/
            // 设置邮件隐秘抄送人,可多个
            /*message.setBcc();*/
            // 设置邮件发送日期
            message.setSentDate(new Date());
            // 创建上下文环境--thym依赖提供方法，使用当前本地前端
            Context context = new Context();
            // 邮件中传递的链接
            context.setVariable("activationUrl",activationUrl);
            // 映射html文件
            String text = templateEngine.process("activation-account.html",context);
            // 设置邮件正文-true-是否是html模板
            message.setText(text,true);

                   } catch (MessagingException e) {
            e.printStackTrace();
        }
        // 发送邮件
        javaMailSender.send(mimeMessage);
    }
}

UserService

package com.expamle.emailloginregister.service;
import com.expamle.emailloginregister.pojo.User;
import org.springframework.transaction.annotation.Transactional;
import java.util.Map;
@Transactional
public interface UserService {
    Map<String,Object> createAccount(User user);
    Map<String, Object> accountLogin(User user);
    Map<String, Object> activationAccount(String confirmCode);
}
