        Properties prop = new Properties();
        //设置协议
        prop.setProperty("mail.transport.protocol","smtp");
        //协议地址
        prop.setProperty("mail.smtp.host","smtp.qq.com");
        //协议地址端口号
        prop.setProperty("mail.smtp.port","465");
        //邮箱授权
        prop.setProperty("mail.smtp.auth","true");
        //QQ邮箱：SSL安全验证

        //创建邮件
        MimeMessage mimeMessage = createMimeMessage(session,"1506214574@qq.com","2673105485@qq.com");
        //建立连接对象
        Transport transport = session.getTransport();
        //打开连接
        transport.connect("1506214574@qq.com","zbijjquxortbgjjd");//建立连接时密码通常是授权码
        transport.sendMessage(mimeMessage,mimeMessage.getAllRecipients());
        //关闭连接
        transport.close();


    }
