ConcurrentModificationException bei der Verwendung von Spring Integration DSL Mail

Ich versuche Spring Integration Java DSL für das Empfangen von E-Mail (Gmail) zu verwenden. Ich benutze auch Redis. Wenn ich Mail erhalte, erhalte ich ConcurrentModificationException. Bei der Suche habe ich auch festgestellt, dass die Leute in Kafka den gleichen Fehler bekommen. Unten ist mein Code und meine Ausnahme.ConcurrentModificationException bei der Verwendung von Spring Integration DSL Mail

Danke für Hilfe ist Fortschritt.

Properties javaMailProperties = new Properties(); 
    javaMailProperties.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
    javaMailProperties.setProperty("mail.imap.socketFactory.fallback", "false"); 
    javaMailProperties.setProperty("mail.store.protocol", "imaps"); 
    javaMailProperties.setProperty("mail.debug", "false"); 
    String imapUrl = "imaps://email%40gmail.com:[email protected]:993/INBOX"; 



    IntegrationFlowBuilder flowBuilder = IntegrationFlows.from(Mail.imapInboundAdapter(imapUrl).javaMailProperties(javaMailProperties).shouldMarkMessagesAsRead(true) 
      , new Consumer<SourcePollingChannelAdapterSpec>() { 


     @Override 
     public void accept(SourcePollingChannelAdapterSpec sourcePollingChannelAdapterSpec) { 
      sourcePollingChannelAdapterSpec 
        .poller(defaultPoller); 
     } 
    }); 
    return flowBuilder.channel(source.output()).get();

Es sieht aus wie wir eine eigene Kryo Serializer (verwendet von Frühling Wolke Stream) für MimeMessage benötigen. Ich öffnete eine JIRA Issue gegen Spring Integration.

Allerdings, als ich es getestet habe, habe ich einen Stapelüberlauffehler, nicht die Ausnahme, die Sie sehen.

Es wäre hilfreich, wenn Sie die Ausgabe der Konsole mit dem mail.debug Javamail-Eigenschaft auf true, mit einer Nachricht anhängen könnte, die Ihr Problem zeigt, auf das Problem JIRA, so dass wir sicher sein können wir dieses Problem zu beheben, denn dann wir kann eine ähnliche MimeMessage rekonstruieren.

EDIT

Eine erste Analyse zeigt das Problem, eine java.util.Logger im session Feld der Mime-Nachricht wird die Serialisierung.

Weiter stellt sich heraus, dass dieses Objekt (AbstractMailReceiver.IntegrationMimeMessage) überhaupt nicht für die Serialisierung geeignet ist, da es den gesamten Anwendungskontext in seinem Bereich hat, da es eine geschachtelte Klasse innerhalb des Mailempfängers ist.

Ich schlage daher vor, einen Transformator in das Mailmodul zu integrieren, um dieses Objekt in ein Objekt zu verwandeln, das für jede Art von Serialisierung geeignet ist.

EDIT2

Eine Abhilfe ist .transform(mailToStringTransformer()) zur Strömung hinzuzufügen. Der E-Mail-Inhalt wird der Hauptteil der Nachricht sein, die Absender von, bcc, cc, to, replyTo und Betreff werden den Kopfzeilen hinzugefügt.

Siehe meine zweite Bearbeitung für eine Problemumgehung, wenn die E-Mail relativ einfach ist. –

Hallo Gary, Danke für deine Antwort. Die Problemumgehung hat funktioniert. 'return flowBuilder.transform (neuer MailToStringTransformer()). channel (source.output()). get();' – Amol
