邮箱验证激活账号

---

1. 流程

• 我们注册账号的时候会收到一封邮件，点击邮件里的链接就激活账号，这个功能很常见。其实就是在用户表里面加state和code字段，state表示激活状态，code是激活码
• 用户填写账号点击注册，接着后台就往数据库插入数据，数据中state字段为0（表示未激活），还有个随机的code
• 之后就向该用户发送邮件，邮件里有一个激活账号的URL（URL有用户id和对应的随机激活码）
• 用户点击邮件的链接，就会带上用户id和激活码来到激活页面激活账号，若邮件的参数和数据库参数一致则激活账号，更新字段state未为1，否则不激活
• 这里只介绍最基本的功能，还有激活码的过期时间，激活不成功删除账号，密码加盐等细节没有实现，还有这里的项目没有前端页面，一切功能从地址栏实现，请各位酌情考虑

2. 环境与依赖

• IDEA
• Maven

2. 项目结构

3. 数据库

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(255) NOT NULL,
  `password` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL,
  `state` int(1) NOT NULL DEFAULT '0' COMMENT '用户激活状态：0表示未激活，1表示激活',
  `code` varchar(255) NOT NULL COMMENT '激活码',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

4. DTO层

public class User {

    private int id;
    private String username;
    private String password;
    private String email;
    private String state;
    private String code;

	//Getters、Setters
    //Constructor
}

5. DAO层

• 使用mybatis动态代理，编写的是接口

@Mapper
public interface UserMapper {

    @Options(useGeneratedKeys = true, keyProperty = "id")
    @Insert("INSERT INTO user (`username`,`password`,`email`,`code`) VALUES (#{username},#{password},#{email},#{code})")
    public int register(User user);

    @Select("SELECT * FROM user WHERE id = #{id}")
    public User getUserById(int id);

    @Update("UPDATE user SET state = 1 WHERE id = #{id} AND code = #{code}")
    public int updateByIdAndCode(int id, String code);
}

6. 工具类

邮件工具类

@Component
public class EmailUtil {

    @Autowired
    private JavaMailSender javaMailSender;

    @Value("${Howl.mail.from}")
    private String from;
    @Value("${Howl.mail.subject}")
    private String subject;
    @Value("${Howl.mail.address}")
    private String address;

    public void sendEmail(int id, String code, String to) {

        String url = address + "/verify?id=" + id + "&code=" + code;
        String label = "<a href=" + url + ">点击此处激活账号，有没有反应可以复制链接从浏览器打开</a>";

        try {
            MimeMessage mimeMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, true);
            messageHelper.setFrom(from);
            messageHelper.setTo(to);
            messageHelper.setSubject(subject);
            messageHelper.setText(label,true);
            messageHelper.setSentDate(new Date());
            javaMailSender.send(mimeMessage);
        }catch (Exception e){
            new RuntimeException("邮件发送失败",e);
        }
    }
}

激活码

@Component
public class CodeUtil {

    public String getCode() {

        //返回UUID
        return UUID.randomUUID().toString().replace("-", "");
    }
}

7. Service层

@Service
public class UserService {

    @Autowired
    UserMapper userMapper;
    @Autowired
    EmailUtil emailUtil;
    @Autowired
    CodeUtil codeUtil;

    public int register(String username, String password, String email) {

        int result;
        String code = codeUtil.getCode();
        User user = new User(username, password, email, code);
        result = userMapper.register(user);

        // 开线程来发邮件，提高效率，发邮件很慢
        new Thread(() -> {
            emailUtil.sendEmail(user.getId(), code, email);
        }).run();
        return result;
    }

    public int verify(int id, String code) {

        User user = userMapper.getUserById(id);
        if (user != null) {
            return userMapper.updateByIdAndCode(id, code);
        }
        return 0;
    }
}

8. Controller层

@RestController
public class UserController {

    @Autowired
    UserService userService;

    @GetMapping(value = "/register")
    public String register(String username, String password, String email) {
        return userService.register(username, password, email) + "";
    }

    @GetMapping(value = "/verify")
    public String verify(int id, String code) {
        return userService.verify(id, code) + "";
    }
}

9. SpringBoot入口

@SpringBootApplication
@MapperScan("com.howl.dao")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

10. 测试

都看到这里了，没有前端页面。。。大家自行想象登录操作

10.1 注册

这里使用地址栏GET方式注册，正式注册用POST表单的不要学我，为了懒不想写前端

10.2 数据库插入

10.3 收邮件

10.4 点击链接激活

10.5 查看数据库激活状态

总结

实现太简单，不过基本功能还是有的，细节方面可以慢慢补充
