邮箱激活，发送邮件

1、添加pom.xml依赖

<!--邮件-->
<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>javax.mail</artifactId>
    <version>1.6.2</version>
</dependency>
<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>javax.mail-api</artifactId>
    <version>1.6.2</version>
</dependency>

2、MailUtils.java

package com.huan.yaya.util;

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

/**
     * 发邮件工具类
     */
public final class MailUtils {
    private static final String USER = "2295958158@qq.com"; // 发件人称号，同邮箱地址
    private static final String PASSWORD = ""; // 如果是qq邮箱可以使户端授权码，或者登录密码
    /**
         * @param to 收件人邮箱
         * @param text 邮件正文
         * @param title 标题
         */
    /* 发送验证信息的邮件 */
    public static boolean sendMail(String to, String text, String title){
        try {
            final Properties props = new Properties();
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.host", "smtp.qq.com");

            // 发件人的账号
            props.put("mail.user", USER);
            //发件人的密码
            props.put("mail.password", PASSWORD);

            // 构建授权信息，用于进行SMTP进行身份验证
            Authenticator authenticator = new Authenticator() {
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    // 用户名、密码
                    String userName = props.getProperty("mail.user");
                    String password = props.getProperty("mail.password");
                    return new PasswordAuthentication(userName, password);
                }
            };
            // 使用环境属性和授权信息，创建邮件会话
            Session mailSession = Session.getInstance(props, authenticator);
            // 创建邮件消息
            MimeMessage message = new MimeMessage(mailSession);
            // 设置发件人
            String username = props.getProperty("mail.user");
            InternetAddress form = new InternetAddress(username);
            message.setFrom(form);

            // 设置收件人
            InternetAddress toAddress = new InternetAddress(to);
            message.setRecipient(Message.RecipientType.TO, toAddress);

            // 设置邮件标题
            message.setSubject(title);

            // 设置邮件的内容体
            message.setContent(text, "text/html;charset=UTF-8");
            // 发送邮件
            Transport.send(message);
            return true;
        }catch (Exception e){
            e.printStackTrace();
        }
        return false;
    }
    public static void main(String[] args) throws Exception { // 做测试用
        MailUtils.sendMail("huanloveyaya@163.com","你好，这是一封测试邮件，无需回复。","测试邮件");
        System.out.println("发送成功");
    }
}

注：此功能需要开通邮箱授权码，参考: https://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

3、邮件激活功能

用户激活即修改用户表中status的值为‘Y’。

• 实体类

  package com.huan.yaya.entity;
  
  import com.baomidou.mybatisplus.annotation.FieldFill;
  import com.baomidou.mybatisplus.annotation.IdType;
  import com.baomidou.mybatisplus.annotation.TableField;
  import com.baomidou.mybatisplus.annotation.TableId;
  import lombok.Data;
  
  import java.util.Date;
  @Data
  public class LiuUser {
      @TableId(type = IdType.AUTO)   //数据库自增，自动赋值
      private Integer id;
      private String name;
      private String num;
      private String password;
      private String sex;
      private String email;
      private String phone;
      private String birthday;
      private String img;
      private String address;
      private String status;  //邮箱激活状态，N代表未激活，Y代表激活
      private String code;  //激活码
      @TableField(fill = FieldFill.INSERT)   //通过Mybatis Plus注解，自动填充
      private Date createTime;
      @TableField(fill = FieldFill.INSERT_UPDATE)
      private Date updateTime;
  
  }

• uuid生成激活码 UuidUtils.java

  package com.huan.yaya.util;
  
  import java.util.UUID;
  
  /**
   * 产生UUID随机字符串工具类
   */
  public final class UuidUtil {
      private UuidUtil(){}
      public static String getUuid(){
          return UUID.randomUUID().toString().replace("-","");
      }
      /**
  	 * 测试
  	 */
      public static void main(String[] args) {
          System.out.println(UuidUtil.getUuid());
          System.out.println(UuidUtil.getUuid());
          System.out.println(UuidUtil.getUuid());
          System.out.println(UuidUtil.getUuid());
      }
  }

• 注册参数,用户注册，发送邮件

  @Override
  public void addUser(LiuUser lu) {
      String password = lu.getPassword();
      lu.setPassword(MD5Util.MD5(password));
      lu.setCode(UuidUtil.getUuid());  //通过UuidUtil随机生成激活码
      lu.setStatus("N");  //设置激活状态
      liuUserMapper.insert(lu);
  
      //邮件正文
      String content = "<a href='http://localhost:9989/yaya/activateCode/?code="+lu.getCode()+"'>点击激活【个人财务管理系统】</a>";
      MailUtils.sendMail(lu.getEmail(),content,"激活邮件");
  }
