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;import java.io.BufferedReader;import java.io.File;import java.io.InputStreamReader;import java.util.Properties;import javax.activation.DataHandler;import javax.activation.DataSource;import javax.activation.FileDataSource;import javax.mail.Address;import javax.mail.BodyPart;import javax.mail.Folder;import javax.mail.Message;import javax.mail.Multipart;import javax.mail.Session;import javax.mail.Store;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeBodyPart;import javax.mail.internet.MimeMessage;import javax.mail.internet.MimeMultipart;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falseAddress from = new InternetAddress("chencheng@infoservice.com.cn");Address to = new InternetAddress("11@qq.com");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!");}/** * 带授权的发送邮件 *  * @throws Exception */public static void setMessageWithAuthentica() throws Exception {Properties props = new Properties();props.put("mail.smtp.host", "smtp.126.com"); // 设置smtp的服务器地址是smtp.126.comprops.put("mail.smtp.auth", "true"); // 设置smtp服务器要身份验证。PopupAuthenticator auth = new PopupAuthenticator();// 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。// 在大多数情况下，使用共享会话就足够了，即使为多个用户邮箱处理邮件会话 也是如此。// 您可以在通信过程的后面一步添加上用户名和密码的组合，并保持所有 的一切是独立的。Session session = Session.getDefaultInstance(props, auth);// 发送人地址Address addressFrom = new InternetAddress(PopupAuthenticator.username,PopupAuthenticator.username);// 收件人地址Address addressTo = new InternetAddress("111@qq.com");// 抄送地址// Address addressCopy = new InternetAddress("haocongping@gmail.com",// "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");message.setFrom(addressFrom);message.addRecipient(Message.RecipientType.TO, addressTo);// message.addRecipient(Message.RecipientType.CC,addressCopy);message.saveChanges();// session.setDebug(true);Transport transport = session.getTransport("smtp"); // 创建连接transport.connect("smtp.126.com", PopupAuthenticator.username,PopupAuthenticator.pwd);// 连接服务器transport.sendMessage(message, message.getAllRecipients()); // 发送信息transport.close(); // 关闭连接System.out.println("邮件发送完毕!");}/** * 带附件的邮件发送 *  * @throws Exception */public static void sendMailWithAttachement() throws Exception {Properties props = System.getProperties();props.put("mail.smtp.host", "smtp.126.com");

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 = "ss@126.com"; // 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 嘿嘿
