最近在设计自己的博客系统，涉及到用户注册与登录验证。

注册这地方我先采用最传统的邮箱验证码方式。具体的实现方式如下：

1.有关如何配置spring boot发送邮件，请参考我的另一篇文章：

https://blog.csdn.net/IndexMan/article/details/87563438

2.搞懂第1步再继续下面的操作

项目源码：https://gitee.com/indexman/mailtest.git

项目总体结构：

1.创建表

创建数据库：test

编码：uft-8

执行以下SQL

SET FOREIGN_KEY_CHECKS=0;-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (`id` int(11) NOT NULL AUTO_INCREMENT,`username` varchar(100) DEFAULT NULL,`password` varchar(100) DEFAULT NULL,`email` varchar(100) DEFAULT NULL,`active_code` varchar(100) DEFAULT NULL,`active_status` int(11) DEFAULT '0',PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2.搭建spring boot环境

2.1 配置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"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.6.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.laoxu.java</groupId><artifactId>mailtest</artifactId><version>0.0.1-SNAPSHOT</version><name>mailtest</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!--mail--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency><!--thymeleaf--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><!--mybatis--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.2</version></dependency><!--Druid数据库连接池--><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.12</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency><!--mysql--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

2.2 配置application.yml文件

server:port: 8080
spring:# 配置发送方信息mail:host: smtp.qq.comusername: 836491123@qq.com  # 邮箱地址password: wlcfnoewxcbaeb123 # 授权码properties:mail:smtp:ssl:enable: true# thymeleafthymeleaf:cache: falseprefix: classpath:/templates/suffix: .htmlmvc:date-format: yyyy-MM-dd# mysqldatasource:driver-class-name: com.mysql.jdbc.Driverusername: rootpassword: root123url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&serverTimezone=GMT&useSSL=falsetype: com.alibaba.druid.pool.DruidDataSource
# mybatis
mybatis:config-location: classpath:mybatis/mybatis-config.xmlmapper-locations: classpath:mybatis/mapper/*.xml

2.3 工具类

/*** @description: ID管理类* @author: luohanye* @create: 2019-04-19**/
public class IDUtils {public static final Logger logger = LoggerFactory.getLogger(IDUtils.class);public static String getUUID(){return UUID.randomUUID().toString().replace("-","");}public static void main(String[] args) {System.out.println(getUUID());logger.debug("test");}
}

3.编写User模型

/*** @description: 用户* @author: luohanye* @create: 2019-04-17**/@Data
public class User implements Serializable {private Integer id;private String username;private String password;private String email;// 激活状态 0 未激活 1 已激活private Integer activeStatus;// 激活码private String activeCode;
}

4.编写UserDao

@Component
public interface UserDao {/***  注册* @param user*/void insert(User user);/***  根据激活码查询用户* @param activeCode* @return*/User selectUserByActiveCode(String activeCode);/***  更新用户* @param user*/void update(User user);/***  查询用户* @param user* @return*/User select(User user);
}

5.编写mapper文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.laoxu.java.mailtest.dao.UserDao"><resultMap id="userMap" type="com.laoxu.java.mailtest.entity.User"><result property="id" column="id"/><result property="username" column="username"/><result property="password" column="password"/><result property="email" column="email"/><result property="activeStatus" column="active_status"/><result property="activeCode" column="active_code"/></resultMap><insert id="insert" parameterType="com.laoxu.java.mailtest.entity.User">insert into user ( username, password,email,active_status,active_code)values (#{username}, #{password}, #{email},#{activeStatus},#{activeCode})</insert><select id="selectUserByActiveCode" parameterType="String" resultType="com.laoxu.java.mailtest.entity.User">select * from user where active_code = #{activeCode}</select><!--激活账户，修改用户状态--><update id="update" parameterType="com.laoxu.java.mailtest.entity.User">update userset active_status=#{activeStatus},username=#{username},password=#{password},email=#{email}, active_status=#{activeStatus},active_code=#{activeCode}where id=#{id}</update><!--登录,根据 activeStatus=1 进行查询--><select id="select" resultType="com.laoxu.java.mailtest.entity.User">select * from user where username=#{username} and password=#{password} and active_status=1</select>
</mapper>

6.编写UserService及其实现

public interface UserService {/***  用户注册* @param user*/void add(User user);/***  根据激活码查找用户* @param activeCode* @return*/User getUserByActiveCode(String activeCode);/*** 修改* @param user*/void modify(User user);/*** 登录* @param user* @return*/User get(User user);
}

/*** @description:* @author: luohanye* @create: 2019-04-18**/
@Service
@Transactional
public class UserServiceImpl implements UserService {@Autowiredprivate UserDao userDao;@Autowiredprivate MailService mailService;@Overridepublic void add(User user) {userDao.insert(user);//获取激活码String code = user.getActiveCode();System.out.println("激活码:"+code);//主题String subject = "来自罗汉爷网站的激活邮件";//上面的激活码发送到用户注册邮箱String context = "<a href=\"http://localhost:8080/user/checkCode?code="+code+"\">激活请点击:"+code+"</a>";//发送激活邮件mailService.sendMimeMail (user.getEmail(),subject,context);}@Overridepublic User getUserByActiveCode(String activeCode) {return userDao.selectUserByActiveCode(activeCode);}@Overridepublic void modify(User user) {userDao.update(user);}@Overridepublic User get(User user) {return userDao.select(user);}
}

7.编写MailService及其实现

public interface MailService {/***  发送多媒体类型邮件* @param to* @param subject* @param content*/void sendMimeMail(String to, String subject, String content);void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId);
}

/*** @description: 邮件处理类* @author: luohanye* @create: 2019-04-19**/
@Service
public class MailServiceImpl implements MailService {private final Logger logger = LoggerFactory.getLogger(this.getClass());@AutowiredJavaMailSenderImpl mailSender;@Value("${spring.mail.username}")private String from;@Overridepublic void sendMimeMail(String to, String subject, String content) {MimeMessage message = mailSender.createMimeMessage();MimeMessageHelper helper = null;try {helper = new MimeMessageHelper(message, true);helper.setFrom(from);helper.setSubject(subject);helper.setTo(to);helper.setText(content, true);mailSender.send(message);//日志信息logger.info("邮件已经发送。");} catch (MessagingException e) {logger.error("发送邮件时发生异常！", e);}}@Overridepublic void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) {MimeMessage message = mailSender.createMimeMessage();MimeMessageHelper helper = null;try{helper = new MimeMessageHelper(message, true);helper.setFrom(from);helper.setSubject(subject);helper.setTo(to);helper.setText(content, true);FileSystemResource fs = new FileSystemResource(new File(rscPath));helper.addInline(rscId, fs);mailSender.send(message);}catch (MessagingException e) {logger.error("发送邮件时发生异常！", e);}}
}

8.前端页面

去看源码。

9.编写UserController

@Controller
@RequestMapping("/user")
public class UserController {@Autowiredprivate UserService userService;/***  注册* @param user* @return*/@RequestMapping(value = "/register")public String register(User user){user.setActiveStatus(0);String activeCode = IDUtils.getUUID();user.setActiveCode(activeCode);userService.add(user);return "success";}/***  校验激活码* @param code* @return*/@RequestMapping(value = "/checkCode")public String checkCode(String code){User user = userService.getUserByActiveCode(code);//如果用户不等于null，把用户状态修改status=1if (user !=null){user.setActiveStatus(1);//把code验证码清空，已经不需要了user.setActiveCode("");userService.modify(user);return "activeSuccess";}return "login";}/*** 登录* @return login*/@RequestMapping(value = "/loginPage")public String login(){return "login";}/*** 登录*/@RequestMapping(value = "/login")public String login(User user, Model model){User u = userService.get(user);if (u !=null){return "welcome";}return "error";}
}

10.编写IndexController

@Controller
public class IndexController {@RequestMapping("/")public String index(){return "index";}
}
