IMAP文件夹收到电子邮件两次

标签： email javamail imap

我正在尝试使用Java mail api开发电子邮件侦听器。我两次收到同样的电子邮件，每次都没有发生这种情况;随机发生。

以下代码用于进行IMAP连接

try {
            isConnecting.set(true);
            createSession();
            LOGGER.warn("session created "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
            store = session.getStore("imap");
            if(store==null){
                LOGGER.warn("store is null return from here"+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                return;
            }
            store.connect(imapServerAddress, imapLoginId, imapPasswrd);
            LOGGER.warn("Connecting successful "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
            folder = store.getFolder(folderName);
            LOGGER.warn("Folder creating "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
            if (timer == null) {
                timer = new HashedWheelTimer(1, TimeUnit.SECONDS);
            }
            if (idleManager == null) {
                idleManager = new IdleManager(session, es);
            }
            if (folder == null || !folder.exists()) {
                LOGGER.warn("invalid folder exit from here "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                System.out.println("Invalid folder");
                return;
            }
            synchronized (folder) {
                LOGGER.warn("Folder sync "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                folder.addConnectionListener(this);
                folder.open(Folder.READ_WRITE);
                folder.addMessageCountListener(this);

                System.out.println("message count listener added");
                LOGGER.warn("message count listner added "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                if (folder instanceof IMAPFolder) {
                    IMAPFolder f = (IMAPFolder) folder;
                    System.out.println("enter idle");
                    LOGGER.warn("Idle condition "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                    idleManager.watch(f);
                    setIsConnected(true);
                    LOGGER.warn("Folder.watch "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                    DbUtil.updateMediaStream(getIdentifier(), true);
                    isConnecting.set(false);
                    connectionAttempt.set(0);
                    LOGGER.warn("Db updated "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                    System.out.println("idle done");
                    scheduleTask();
                    LOGGER.warn("Scheduler starts "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                }

            }

            System.out.println(new Date()
                    + "================================== connect() end");
            LOGGER.warn("____________________END connecting "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
        } catch (Exception fex) {

                if (connectionAttempt.get() >= 3) {
                    LOGGER.error("Reconnection Failed", fex);
                    connectionAttempt.set(0);
                    throw new IllegalStateException(
                            "Error while connecting mediaStream", fex);
                }
                LOGGER.error("Reconnecting mediastream attempt "
                        + connectionAttempt.get(), fex);
                connectionAttempt.incrementAndGet();
                closeFolderAndStore();
                connect();

        }

此处收到电子邮件，“public void messagesAdded（MessageCountEvent ev）”方法调用两次 

@Override
    public void messagesAdded(MessageCountEvent ev) {
        Message[] msgs = ev.getMessages();
        System.out.println("Got " + msgs.length + " new messages");
        LOGGER.info("New message received {}" ,msgs.length);
        // Just dump out the new messages

        for (int i = 0; i < msgs.length; i++) {

            try {

                // msgs[i].writeTo(System.out);

                    System.out.println("-----");
                    System.out.println("Message >>" + msgs[i].getMessageNumber()
                            + ":");
                    LOGGER.info("Email Received >>> {}" , msgs[i].getMessageNumber());
                    processEmail(msgs[i]);


            } catch (Exception ioex) {
                LOGGER.error("messagesAdded:getmessagenumber", ioex);
                ioex.printStackTrace();
            }
        }
        try {
            synchronized (folder) {
                if (folder != null && idleManager != null) {
                    idleManager.watch(folder);
                }
            }
        } catch (Exception e) {
            LOGGER.error("messagesAdded:watch", e);
            e.printStackTrace();
        }
    }

主体“test”的电子邮件正在重复

1 个答案:

答案 0 :(得分：1)

这是邮箱中的邮件号码466。服务器宣布新消息：

    * 3 RECENT
    * 466 EXISTS

您处理消息：

    A16 FETCH 466 (ENVELOPE INTERNALDATE RFC822.SIZE)
    ...

您等待新消息，服务器会告诉您：

    * 466 EXPUNGE
    * 466 EXISTS

这意味着邮箱号码466已完全从邮箱中删除，邮箱中有一条新邮件号码466。 JavaMail会通知您新的消息号466.显然，它与删除的消息号466完全相同。

我不知道为什么服务器会这样做。对我来说，它看起来像服务器中的一个错误。 请向Microsoft报告。

您可能需要查看正在处理的邮件的IMAP UID。新消息466绝对必须具有不同的UID。如果没有，那就是服务器中的一个更严重的错误。

您还可以查看邮件的Message-ID，以确保之前没有看到该邮件。如果所有错误情况都是这样，您可能只需要保留一条消息的历史记录。但请注意，虽然Message-ID是唯一的，并且通常是唯一的，但与IMAP UID不同，不能保证它们 唯一，甚至根本不存在。
