		// 1.創建一個程序與郵件服務器會話對象 Session
		Properties props = new Properties();
		props.setProperty("mail.transport.protocol", "SMTP");//發郵件的協議
		props.setProperty("mail.host", "smtp.163.com");//發送郵件的服務器地址
		props.setProperty("mail.smtp.auth", "true");// 指定驗證爲true

		// 創建驗證器
		Authenticator auth = new Authenticator() {
			public PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication("賬號", "密碼或者是授權碼");//發郵件的賬號的驗證
			}
		};

		Session session = Session.getInstance(props, auth);

		// 2.創建一個Message，它相當於是郵件內容
		Message message = new MimeMessage(session);

		message.setFrom(new InternetAddress("****@java.com")); // 設置發送者

		message.setRecipient(RecipientType.TO, new InternetAddress(email)); // 設置發送方式與接收者

		message.setSubject(subject);//郵件的主題

		message.setContent(emailMsg, "text/html;charset=utf-8");

		// 3.創建 Transport用於將郵件發送
		Transport.send(message);
