如何使用Java发送qq邮件

方法:

1.前提准备工作：

首先，邮件的发送方要开启POP3 和SMTP服务--即发送qq邮件的账号要开启POP3 和SMTP服务

2.开启方法：

登陆qq邮箱

3.点击 设置

4.点击—-账户

5.找到：POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务 —点击开启

6.送短信 —–点击确定

7.稍等一会，很得到一个授权码! –注意：这个一定要记住，一会用到

8.点击保存修改 —OK 完成

9.java 测试代码：

package cn.cupcat.test;

import java.util.Properties;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMessage.RecipientType;

public class SendmailUtil {

public static void main(String[] args) throws AddressException, MessagingException {

Properties properties = new Properties();

properties.put("mail.transport.protocol", "smtp");// 连接协议

properties.put("mail.smtp.host", "smtp.qq.com");// 主机名

properties.put("mail.smtp.port", 465);// 端口号

properties.put("mail.smtp.auth", "true");

properties.put("mail.smtp.ssl.enable", "true");//设置是否使用ssl安全连接 ---一般都使用

properties.put("mail.debug", "true");//设置是否显示debug信息 true 会在控制台显示相关信息

//得到回话对象

Session session = Session.getInstance(properties);

// 获取邮件对象

Message message = new MimeMessage(session);

//设置发件人邮箱地址

message.setFrom(new InternetAddress("123456789@qq.com"));

//设置收件人地址 message.setRecipients( RecipientType.TO, new InternetAddress[] { new InternetAddress("987654321@qq.com") });

//设置邮件标题

message.setSubject("这是第一封Java邮件");

//设置邮件内容

message.setText("内容为： 这是第一封java发送来的邮件。");

//得到邮差对象

Transport transport = session.getTransport();

//连接自己的邮箱账户

transport.connect("123456789@qq.com", "vvctybgbvvophjcj");//密码为刚才得到的授权码

//发送邮件 transport.sendMessage(message, message.getAllRecipients());

}

}我爱编程网

10.运行就会发出邮件了。。。。

下面是我收到邮件的截图，当然我把源码中的邮件地址都是修改了，不是真实的，你们测试的时候，可以修改能你们自己的邮箱。最后，祝你也能成功，如果有什么问题，可以一起讨论!

注意事项

得到的授权码一定要保存好，程序中要使用

要实现邮件发送功能需要导入包：mail.jar

transport.sendMessage(message, message

// transport.send(message);

transport.close();

}

}

这是我以前用的 现在有些需要验证的邮箱可用用不了，用不了的话HI我

package mail;

import java.util.*;

import javax.mail.*;

import javax.mail.internet.*;

public class SendMail{

public static void main(String[] args) {

send("标题","内容");

}

public static void send(String h ,String b ) {

try {

Properties p = new Properties(); //Properties p = System.getProperties();

p.put("mail.smtp.auth", "true");

p.put("mail.transport.protocol", "smtp");

p.put("mail.smtp.host", "smtp.139.com");

p.put("mail.smtp.port", "25");

//建立会话

Session session = Session.getInstance(p);

MimeMessage msg = new MimeMessage(session); //建立信息

msg.setFrom(new InternetAddress("bjyyzx@139.com")); //发件人

// msg.setRecipient(MimeMessage.RecipientType.TO,

// new InternetAddress("rewfff@139.com zhu_yajun@139.com")); //收件人

Address []address=new Address[]{new InternetAddress("bbb@139.com"),new InternetAddress("aaa@139.com")};

msg.setRecipients(MimeMessage.RecipientType.TO,

address); //收件人

msg.setSentDate(new Date()); // 发送日期

msg.setSubject(h); // 主题

msg.setText(b); //内容

// 邮件服务器进行验证

Transport tran = session.getTransport("smtp");

tran.connect("smtp.139.com", "bluebit_cn", "xiaohao");

// bluebit_cn是用户名，xiaohao是密码

tran.sendMessage(msg, msg.getAllRecipients()); // 发送

//System.out.println("邮件发送成功");

} catch (Exception e) {

e.printStackTrace();

}
