			throws AddressException, MessagingException {
		// 1.创建一个程序与邮件服务器会话对象 Session

		Properties props = new Properties();
		props.setProperty("mail.transport.protocol", "SMTP");//发送协议
		props.setProperty("mail.host", "smtp.163.com");//邮箱服务器地址
		props.setProperty("mail.smtp.auth", "true");// 指定验证为true

		// 创建验证器
		Authenticator auth = new Authenticator() {
			public PasswordAuthentication getPasswordAuthentication() {// ↓ 发送者的邮箱名和密码(这里也可以设置为授权码，防止邮箱被盗取)
				return new PasswordAuthentication("176****[email protected]", "w****2");
			}
		};

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

		// 2.创建一个Message，它相当于是邮件内容
		Message message = new MimeMessage(session);

		message.setFrom(new InternetAddress("176****[email protected]")); // 设置发送者

		message.setRecipient(RecipientType.TO, new InternetAddress(email)); // 设置发送方式与接收者

		message.setSubject("用户激活");
		// message.setText("这是一封激活邮件，请<a href='#'>点击</a>");

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

		// 3.创建 Transport用于将邮件发送

		Transport.send(message);
	}
}

调用者：

String emailMsg = "恭喜您注册成功，请点击下面的连接进行激活账户"
					+ "<a href='http://localhost:9100/shop/active?
activeCode="+activeCode+"'>"
							+ "http://localhost:9100/shop/active?activeCode="+activeCode+"</a>";

				MailUtils.sendMail(user.getEmail(), emailMsg);  从表单获取的用户邮箱
