首先需要配置QQ邮箱，开启功能，获取授权码。

具体JAVA代码如下：

Properties props = System.getProperties();
    
            props.setProperty("mail.smtp.host", "smtp.qq.com");
    
            props.setProperty("mail.smtp.socketFactory.fallback", "false");
    
            props.setProperty("mail.smtp.port", "465");
    
            props.setProperty("mail.smtp.socketFactory.port", "465");
    
            props.put("mail.smtp.auth", "true");
    
        
            // 使用ssl加密传输,解决ssl证书报错问题
            MailSSLSocketFactory sf = new MailSSLSocketFactory();
            sf.setTrustAllHosts(true);
    
            props.put("mail.smtp.ssl.enable", "true");
    
            props.put("mail.smtp.ssl.socketFactory", sf);
            final String username = "123456789@qq.com";//发件人邮箱
    
            final String password = "xcvbgtrejpouhl";//开启QQ邮箱smtp功能给的授权码,当qq邮箱密码使用
    
            Session session = Session.getDefaultInstance(props, new Authenticator() {
    
                protected PasswordAuthentication getPasswordAuthentication() {
    
                    return new PasswordAuthentication(username, password);
    
                }
            });
    
            session.setDebug(true);//在控制台打印发送邮件日志信息
    
          
    
            Message msg = new MimeMessage(session);
    
           
    
            msg.setFrom(new InternetAddress(username));
    
            msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse("123456789@qq.com", false));//收件人邮箱
    
            msg.setSubject("验证码");//邮件标题(邮件标题,避免被QQ邮箱当垃圾扔进垃圾桶)
    
            msg.setText("184698");//邮件文本内容
    
            msg.setSentDate(new Date());
    
            Transport.send(msg);
    
            System.out.println("Message sent successful");
