java-Mail

JAVA邮件开发包括两大方面：

发送与接收邮件：

创建与解析邮件内容：

邮件服务器按通讯协议可以分为两种类型：

SMTP服务器

POP3/IMAP服务器



发送邮件用的是SMTP服务器,接收邮件是通过POP3服务器

发送邮件的最简单的代码：

package com.szy.mail;

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 Demo1 {

/**
* @param args
*/
public static void main(String[] args) throws Exception{
// TODO Auto-generated method stub
Properties props = new Properties();
props.setProperty("mail.smtp.auth", "true");
props.setProperty("mail.transport.protocol", "smtp");
Session session = Session.getInstance(props);
session.setDebug(true);

Message msg = new MimeMessage(session);
//msg.setContent("你好啊");
msg.setFrom(new InternetAddress("295508987@qq.com"));

Transport  transport = session.getTransport();
transport.connect("smtp.sina.com",25,"sun29550","woheni1314");
//transport.send(msg,new Address[]{new InternetAddress("sunzhiyan_syspro@163.com")});
transport.sendMessage(msg,new Address[]{new InternetAddress("295508987@qq.com")});
transport.close();
}

}
