First, configure your Gmail account to accept POP3 access. Then, simply access your mail account using Javamail !

You can use the Javamail for that. The thing to remember is that GMail uses SMTPS not SMTP.
您可以为此使用 Javamail。需要记住的是 GMail 使用 SMTPS 而不是 SMTP。
import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
public class SimpleSSLMail {
private static final String SMTP_HOST_NAME = "smtp.gmail.com";
private static final int SMTP_HOST_PORT = 465;
private static final String SMTP_AUTH_USER = "[email protected]";
private static final String SMTP_AUTH_PWD = "mypwd";
public static void main(String[] args) throws Exception{
new SimpleSSLMail().test();
}
public void test() throws Exception{
Properties props = new Properties();
props.put("mail.transport.protocol", "smtps");
props.put("mail.smtps.host", SMTP_HOST_NAME);
props.put("mail.smtps.auth", "true");
// props.put("mail.smtps.quitwait", "false");
Session mailSession = Session.getDefaultInstance(props);
mailSession.setDebug(true);
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("Testing SMTP-SSL");
message.setContent("This is a test", "text/plain");
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("[email protected]"));
transport.connect
(SMTP_HOST_NAME, SMTP_HOST_PORT, SMTP_AUTH_USER, SMTP_AUTH_PWD);
transport.sendMessage(message,
message.getRecipients(Message.RecipientType.TO));
transport.close();
}
}

Variations of this question have been addressed in several earlier posts:
这个问题的变化已经在之前的几篇文章中得到了解决：
- Getting mail from GMail into Java application using IMAP
- How do you send email from a Java app using Gmail?
The general approach is to use IMAP/SMTP via JavaMail. The FAQeven has a special entry for working with Gmail.
