java代码实现邮件发送

1、在我的资源库里面下载支持的jar包，
2、测试代码：
[java]
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(); www.zzzyk.com
    }
}

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
