我一直在使用入站通道適配器代碼工作完美，但它拋出這個特殊的例外，這我不能夠解決Spring集成

我使用了一個一行映射配置的輸出來實現一個輪詢存儲結果集的bean的對象形式。
我只是在這個問題上遇到了麻煩，而我的Spring集成項目造成了mqtt連接問題。 stacktrace有點嚇人:)（特別是在我的情況下，因爲我的項目在一段時間後簡單地停止處理消息）。我認爲這與棧跟蹤有關，但顯然不是。根據文檔，Assert通常用於「在運行時及早明確地識別程序員錯誤」。看起來這只是一個內部調試消息沒有？這裏的堆棧跟蹤真的很需要嗎？ – ddewaele 2014-07-16 12:57:07
我同意這有點可怕，我已經打開了一個[JIRA問題]（https://jira.spring.io/browse/INT-3474），我們將嘗試解決它。關於MQTT，我們注意到Paho客戶端在連接關閉期間無限期地被阻塞。隨後，我們切換（在主服務器上）使用異步客戶端，以便我們始終能夠執行任何操作。不知道這是否與你的問題有關，但我想我會提到它。 – 2014-07-16 13:22:54
Thx很多！現在我已經把所有的東西都放在調試模式中，看看是否有一些亮光。問題發生時將嘗試進行一些線程轉儲。 （我想我應該看到線程轉儲中的阻塞問題？） – ddewaele 2014-07-16 13:35:22
