Java Mail 发布邮件

以下是是发送邮件的JavaMail 实现，加入工程即可用，不过邮箱信息需要更换。。。

package com.mail;

public class TestSendMail {
	public static void main(String[] arg) throws Exception {
		sendMailWithAttachement();
	}

	/**
	 * 不需要验证的邮件发送
	 * 
	 * @throws Exception
	 */
	public static void setMessage() throws Exception {
		Properties props = System.getProperties();
		props.put("mail.smtp.host", "mail.infoservice.com.cn"); // 设置smtp的服务器地址：该邮件服务器不需要身份验证
		props.put("mail.smtp.auth", "false"); // 设置smtp服务器要身份验证:缺省设置为false

		Address from = new InternetAddress("[email protected]");
		Address to = new InternetAddress("[email protected]");

		Session session = Session.getDefaultInstance(props, null);
		Message message = new MimeMessage(session);
		message.setFrom(from);
		message.addRecipient(Message.RecipientType.TO, to);
		message.setText("I love U!!!");
		message.setSubject("Test");

		Transport.send(message);
		System.out.println("邮件发送完毕!");
	}

	/**

		// Session 类定义了一个基本的邮件会话。通过该会话可让别的工作顺利执行。

		// Address addressCopy = new InternetAddress("[email protected]",
		// "George Bush");
		// 可以通过将Session对象传递给MimeMessage构造 器的方法来创建消息
		// 一个MimeMessage是一种理解MIME类型和报头（在不同的RFC文档中 均有定义）的消息。
		// 消息的报头被严格限制成只能使用US-ASCII字符，尽管非 ASCII字符可以被编码到某些报头字段中。
		Message message = new MimeMessage(session);
		message.setContent("This is mail content!", "text/plain");// 或者使用message.setText("Hello");更详细的信息请参看后续文章.
		message.setSubject("测试邮件标题");

		Transport transport = session.getTransport("smtp"); // 创建连接
		transport.connect("smtp.126.com", PopupAuthenticator.username,

		transport.sendMessage(message, message.getAllRecipients()); // 发送信息
		transport.close(); // 关闭连接

}

下面是你要哪个邮箱发送的验证信息类

package com.mail;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class PopupAuthenticator extends Authenticator {
	public static String username = "[email protected]"; // 邮箱登录帐号
	public static String pwd = "11"; // 登录密码

	public PasswordAuthentication getPasswordAuthentication() {
		return new PasswordAuthentication(username, pwd);
	}
}

最下面 是上面两个类的源码
