2026 JAVA QQ邮箱发邮件工具类，拿来就用！

先上效果

一、pom依赖

<!--QQ邮箱所需要的依赖-->
<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.mail</artifactId>
    <version>3.0-b47</version>
</dependency>     

二、工具类

自定义自己的QQ邮箱和设置邮箱授权码以及业务逻辑！！！

import com.sun.mail.util.MailSSLSocketFactory;

import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Date;
import java.util.Properties;
