Java操作应用——邮件发送

题目答案

在Java中发送邮件也很简单。你只需装一下Java Mail这个jar包，放到你的类路径里即可。在下面的代码中，我们设置了几个基础属性，然后便可以发送邮件了：

import java.util.*;

import javax.mail.*;

import javax.mail.internet.*;

public class SendEmail

{

public static void main(String [] args)

{

String to = "recipient@gmail.com" ;

String from = "sender@gmail.com" ;

String host = "localhost" ;

Properties properties = System.getProperties();

properties.setProperty( "mail.smtp.host" , host);

Session session = Session.getDefaultInstance(properties);

try {

MimeMessage message = new MimeMessage(session);

message.setFrom( new InternetAddress(from));

message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

message.setSubject( "My Email Subject" );

message.setText( "My Message Body" );

Transport.send(message);

System.out.println( "Sent successfully!" );

}

catch (MessagingException ex) {

ex.printStackTrace();

}
