是否有任何好的短代码示例只是阅读新的Gmail邮件？

Question

我一直在尝试编写一个定期解析gmail消息内容的应用程序.我已经阅读了JavaMail常见问题解答,我已经查看了JavaMail下载包中的一些示例,但是无法使其工作.下面的代码当前导致以下gmail错误:

主持人尚未解决:imaps.gmail.com:993

我也试过imap.gmail.com:143但得到:

主持人尚未解决:imap.gmail.com:143

任何帮助或建议将不胜感激.GMailReader是我用来尝试返回gmail imap消息的类:

public class GMailReader extends javax.mail.Authenticator { 
    private String mailhost = "imaps.gmail.com"; 
    private String user; 
    private String password; 
    private Session session; 
    public GMailReader(String user, String password) { 
        this.user = user; 
        this.password = password; 
        Properties props = new Properties(); 
        props.setProperty("mail.transport.protocol", "imaps"); 
        props.setProperty("mail.imaps.host", mailhost); 
        props.put("mail.imaps.auth", "true"); 
        props.put("mail.imaps.port", "993"); 
        props.put("mail.imaps.socketFactory.port", "993"); 
        props.put("mail.imaps.socketFactory.class", 
                  "javax.net.ssl.SSLSocketFactory"); 
        props.put("mail.imaps.socketFactory.fallback", "false"); 
        props.setProperty("mail.imaps.quitwait", "false"); 
        session = Session.getDefaultInstance(props, this); 
    } 
    public synchronized Message[] readMail() throws Exception { 
        try { 
            Store store = session.getStore("imaps"); 
            store.connect("imaps.gmail.com", user, password); 
            Folder folder = store.getFolder("INBOX"); 
            folder.open(Folder.READ_ONLY); 
            Message[] msgs = folder.getMessages(1, 10); 
            FetchProfile fp = new FetchProfile(); 
            fp.add(FetchProfile.Item.ENVELOPE); 
            folder.fetch(msgs, fp); 
            return msgs; 
        } catch (Exception e) { 
            Log.e("readMail", e.getMessage(), e); 
            return null; 
        } 
    } 
}

我在这里找到了一个有用的例子.我的错误是使用"mail.transport.protocol"而不是"mail.store.protocol".
