javamail邮件开发入门(2)

简单的接收邮件的例子：

public static void main(String[] args) {
        Properties props = new Properties();
        props.put("mail.store.protocol", "pop3");
        props.put("mail.pop3.auth ", "true");
        Session session = Session.getInstance(props, null);
        session.setDebug(true);
        try {
            Store store = session.getStore();
            store.connect("pop.qq.com", "[e-mail]", "xx520gaoyong");
            Folder folder = store.getFolder("inbox");
            folder.open(Folder.READ_ONLY);
            Message message = null;
            if (folder.getMessages().length > 0) {
                message = folder.getMessages()[0];
            }
            System.out.println("*******内容如下*******");
            System.out.println(message.getSubject());
            System.out.println("*************************");
            folder.close(true);
            store.close();
        } catch (MessagingException mex) {
            System.out.println("send failed, exception: " + mex.getMessage());
        }
    }
