        private String host = "smtp.126.com";
        //发送邮件的固定端口
        private String port = "25";
        /**邮箱账号*/
        private String userName = "xxx";
        /**客户端授权密码非邮箱账号密码 这里我的是本人163的登录密码*/
        private String password = "xxx";
        /**发给谁*/
        private String to = "xiangxizhanghui@163.com";
    
        @Test
        public void sendTextMail() throws Exception
        {
            Properties pro = System.getProperties();
            pro.put("mail.smtp.host", host);
            pro.put("mail.smtp.port", port);
            pro.put("mail.smtp.auth", "true");
    
            // 根据邮件会话属性和密码验证器构造一个发送邮件的session
            Session sendMailSession = Session.getDefaultInstance(pro,
                    new Authenticator()
                    {
                        @Override
                        protected PasswordAuthentication getPasswordAuthentication()
                        {
                            return new PasswordAuthentication(userName, password);
                        }
                    });
            // 根据session创建一个邮件消息
            Message mailMessage = new MimeMessage(sendMailSession);
            // 设置邮件消息的发送者
            mailMessage.setFrom(new InternetAddress(userName));
            // 创建邮件的接收者地址，并设置到邮件消息中
            mailMessage.setRecipient(Message.RecipientType.TO,new InternetAddress(to));
            // 设置邮件消息的主题
