package main;

import java.io.UnsupportedEncodingException;
import java.util.Properties;

import javax.mail.Address;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class Class1{
public static void main(String args[]) throws MessagingException, UnsupportedEncodingException{
String host = "SMTP.sina.com";
String from = "xiaoxi@sina.com";
String to = "guoxiaoxi@staff.hexun.com";
// Get system properties
Properties props = System.getProperties();
// Setup mail server
//props.put("mail.transport.protocol","smtp");
props.put("mail.smtp.host", host);
//props.put("mail.smtp.port","25");
props.put("mail.smtp.auth","true");

MyAuthenticator myauth = new MyAuthenticator("xiaoxi@sina.com", "123");
Session session = Session.getDefaultInstance(props, myauth);

// Get session
//Session session = Session.getDefaultInstance(props, null);
// Define message
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
message.setSubject("Hello JavaMail");
message.setText("Welcome to JavaMail");

// Send message
Transport.send(message);
//Transport transport = session.getTransport("smtp");
//transport.connect("smtp.sina.com", "xiaoxi@sina.com", "123"); /// 这里的地址要与标志1的地址雷同.
//transport.sendMessage(message, message.getAllRecipients());

System.out.println("发送完毕！");
}
