1.配置环境

1.1pom.xml中添加依赖

    <!--javamail-->
    <dependency>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
      <version>1.3.2</version>
    </dependency>

1.2实体类User

package com.gym.pojo;

import lombok.Data;

@Data
public class User {
    private Integer userId;

    private String userName;

    private String userPassword;

    private String userEmail;

    private String userPhone;

    private String userPhoto;

    private Integer userState;

    private String userCode;

}

1.3编写UUIDUtils随机生成激活码

package com.gym.util;

import java.util.UUID;

/**
 * 生成随机字符串
 */
public class UUIDUtils {

    public static String getUUID(){
        return UUID.randomUUID().toString().replace("-","");
    }
}

1.4编写MailUtils

package com.gym.util;

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;

public class MailUtils {

    /**
     * 发送邮件的方法
     * @param userEmail
     * @param userCode
     */
    public static void sendMail(String userEmail,String userCode) throws Exception {

        //1.创建连接对象，连接到邮箱服务器
        Properties properties = new Properties();
        properties.put("mail.smtp.localhost", "163.com"); 
        properties.put("mail.smtp.host","smtp.163.com");
        properties.put("mail.smtp.auth","true");

        MailAuthenticator mailAuthenticator = new MailAuthenticator("邮箱名【不要加邮箱后缀】","客户端授权密码");
        Session session = Session.getInstance(properties,mailAuthenticator);
        //开启session的调试模式，可以查看当前邮件发送状态
        session.setDebug(true);
        //2.创建邮件对象
        Message message = new MimeMessage(session);
        //2.1设置发件人
        message.setFrom(new InternetAddress("发件人邮箱，需要后缀如[email protected]"));
        //2.2设置收件人
        message.setRecipient(Message.RecipientType.TO,new InternetAddress(userEmail));
        //2.3设置邮件主题
        message.setSubject("来自xxx的激活邮件");
        //2.4设置邮件的征文
        message.setContent("<h1>来自xxx的激活邮件,激活请点击以下链接：<h1><h3><a href='http://localhost:8080/user/activity.do?code="+userCode+"'>http://localhost:8080/user/activity.do?code="+userCode+"</a></h3>","text/html;charset=UTF-8");
        //3.发送一封激活邮件
        Transport.send(message);
    }
}

class MailAuthenticator extends Authenticator {
    /**
     * 用户名
     */
    private String username;
    /**
     * 密码(客户端授权密码)
     */
    private String password;
    /**
     * 创建一个新的实例 MailAuthenticator.
     *
     * @param username
     * @param password
     */
    public MailAuthenticator(String username, String password) {
        this.username = username;
        this.password = password;
    }
    public String getPassword() {
        return password;
    }   @
            Override  protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(username, password);
    }
    public String getUsername() {
        return username;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public void setUsername(String username) {
        this.username = username;
    }

}

1.5编写UserController.java

package com.gym.controller;

import com.gym.pojo.User;
import com.gym.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/user/")
public class UserController {

    @Autowired
    private UserService userSerivce;

    @RequestMapping(value = "register.do",method = RequestMethod.POST)
    @ResponseBody
    private void register(User user) throws Exception {
        userSerivce.register(user);
    }
}

1.6编写UserService和UserServiceImpl

package com.gym.service;

import com.gym.pojo.User;

public interface UserService {
    void register(User user) throws Exception;
}

package com.gym.service.Impl;

import com.gym.dao.UserMapper;
import com.gym.pojo.User;
import com.gym.service.UserService;
import com.gym.util.MailUtils;
import com.gym.util.UUIDUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService{

    @Autowired
    private UserMapper userMapper;


    /**
     * 用户注册
     * @param user
     */
    public void register(User user) throws Exception {
        //1.插入用户到数据库
        user.setUserState(0);
        user.setUserCode(UUIDUtils.getUUID()+ UUIDUtils.getUUID());
        userMapper.insert(user);

        //2.发送邮箱激活
        MailUtils.sendMail(user.getUserEmail(),user.getUserCode());
    }
}
