1、在我的资源库里面下载支持的jar包，下载地址：http://download.csdn.net/detail/harderxin/4451541

2、测试代码：

package com.email.test;import java.util.Properties;import javax.mail.Address;import javax.mail.Message;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;public class TestEmail {public void SendEmailTest() {Properties props = new Properties();props.put("mail.smtp.host", "smtp.qq.com");props.put("mail.smtp.auth", "true"); // 允许smtp校验Session sendMailSession = Session.getInstance(props, null);try {Transport transport = sendMailSession.getTransport("smtp");// 连接你的QQ，注意用户名和密码必须填写正确，否则权限得不到transport.connect("smtp.qq.com", "3693352@qq.com", "****");Message newMessage = new MimeMessage(sendMailSession);// 设置mail主题String mail_subject = "更改邮件发送人测试";newMessage.setSubject(mail_subject);// 设置发信人地址String strFrom = "517122199@qq.com";strFrom = new String(strFrom.getBytes(), "iso-8859-1");newMessage.setFrom(new InternetAddress(strFrom));// Address addressFrom[] = { new// InternetAddress("617334015@qq.com"),new// InternetAddress("goodnight0002@163.com") };// 改变发件人地址// newMessage.addFrom(addressFrom);// 设置收件人地址Address addressTo[] = { new InternetAddress("306220165@qq.com") };newMessage.setRecipients(Message.RecipientType.TO, addressTo);// 设置mail正文newMessage.setSentDate(new java.util.Date());String mail_text = "java实现邮件发送！";newMessage.setText(mail_text);newMessage.saveChanges(); // 保存发送信息transport.sendMessage(newMessage, newMessage.getRecipients(Message.RecipientType.TO)); // 发送邮件transport.close();// Transport.send(newMessage);System.out.println("发送成功!");} catch (Exception e) {System.out.println("发送失败！");System.out.println(e);}}public static void main(String args[]) throws Exception {TestEmail SEmail = new TestEmail();SEmail.SendEmailTest();}}

3、注意：

1）在初次进行发送的时候，必须将你的邮箱设置为允许smtp校验，否则邮件发送不出去

2）填写正确的邮件权限、邮件名称和密码，否则会抛出异常
