java代码兑现邮件发送

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，下载地址：http://download.****.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
