log4j 发email 补充

其实，那个牛人的方法有些麻烦，虽然SMTPAppender的smtpusername等属性是private的，但是有getsmtpusername()方法可以获得他们，所以只要改变

activateOptions()方法就可以，其他的只要继承SMTPAppender.class就可以了

具体代码如下

package com.hua.test;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import org.apache.log4j.helpers.LogLog;
import org.apache.log4j.net.SMTPAppender;

/**
 * SMTP Appender扩展，增加对邮件认证的支持
 * 
 * @author hua
 * 
 */
public class SMTPHua2Appender extends SMTPAppender {
	private String smtpAuth;



	public String getSmtpAuth() {
		return smtpAuth;
	}



	public void setSmtpAuth(String smtpAuth) {
		this.smtpAuth = smtpAuth;
	}



	@Override
	public void activateOptions() {
		// TODO Auto-generated method stub
		Properties props = new Properties(System.getProperties());
		Authenticator authenticator = null;
		
		if (getSMTPHost() != null)
			props.put("mail.smtp.host", getSMTPHost());

		/**//* ADD auth code */
		if (smtpAuth != null && smtpAuth.trim().equals("true")) {
			props.put("mail.smtp.auth", "true");
			authenticator = new Authenticator() {
				protected PasswordAuthentication getPasswordAuthentication() {
					return new PasswordAuthentication(getSMTPUsername(),
							getSMTPPassword());
				}
			};
		}

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

		msg = new MimeMessage(session);
		try {
			InternetAddress fromAdd=new InternetAddress(getFrom());
			InternetAddress[] toAdd=InternetAddress.parse(getTo());
			if (getFrom() != null)
				msg.setFrom(fromAdd);
			else
				msg.setFrom();

			msg.setRecipients(Message.RecipientType.TO, toAdd);
			if (getSubject() != null)
				msg.setSubject(getSubject());
		} catch (MessagingException e) {
			LogLog.error("Could not activate SMTPAppender options.", e);
		}
	}

}
