Java邮箱自动发送邮件

Android开发中，当忘记密码需要找回密码的时候，很多情况都是向注册邮箱自动发送注册登录密码，自己写的一个自动发送邮件的java类，亲测可用。

直接贴代码：

public class SendMail {

	static int port = 25;//端口号
	static String server = "smtp.163.com";// 邮件服务器mail.cpip.net.cn
	static String from = "小明";// 发送者,显示的发件人名字
	static String user = "[email protected]";// 发送者邮箱地址
	static String password = "xxxxxx";// 密码

	public static void sendEmail(String email, String subject, String body)
			throws UnsupportedEncodingException {
		try {
			Properties props = new Properties();
			props.put("mail.smtp.host", server);
			props.put("mail.smtp.port", String.valueOf(port));
			props.put("mail.smtp.auth", "true");
			Transport transport = null;
			Session session = Session.getDefaultInstance(props, null);
			transport = session.getTransport("smtp");
			transport.connect(server, user, password);
			MimeMessage msg = new MimeMessage(session);
			msg.setSentDate(new Date());
			InternetAddress fromAddress = new InternetAddress(user, from,
					"UTF-8");
			msg.setFrom(fromAddress);
			InternetAddress[] toAddress = new InternetAddress[1];
			toAddress[0] = new InternetAddress(email);
			msg.setRecipients(Message.RecipientType.TO, toAddress);
			msg.setSubject(subject, "UTF-8");
			msg.setText(body, "UTF-8");
			msg.saveChanges();
			transport.sendMessage(msg, msg.getAllRecipients());
		} catch (NoSuchProviderException e) {
			e.printStackTrace();
		} catch (MessagingException e) {
			e.printStackTrace();
		}
	}
}

sendEmail(String email, String subject, String body)

email为发送的目的邮箱，subject邮件主题，body邮件内容。
