用Apache Camel訪問Ebay商業集成平臺（MIP）

我們想用apache駱駝訪問eBay商家集成平臺（mip）。它的「sftp服務器像」協議服務於你將工作的目錄結構。用Apache Camel訪問Ebay商業集成平臺（MIP）

所以這是一個用Apache Camel處理目錄的主要例子。

但是我們遇到了錯誤，因爲mip-interface不顯示（或者不具有）技術「。」和「..」目錄。

任何人都可以給我一個提示

如何配置Apache的駱駝，它可以處理沒有目錄結構「」和「..」？或者
有沒有更好的方法來訪問eBay與java工具，支持海量數據操作？

在此先感謝。

OMG - 簡單的解決方案是發現：

設置逐步=假將解決這個問題。

爲什麼？在看看到SftpConsumer.doPollDirectory（）後，我找到了一個不錯的IF-THEN-ELSE塊：

if (isStepwise()) { 
     files = operations.listFiles(); 
    } else { 
     files = operations.listFiles(dir); 
    }

如果逐步被設置爲false，那麼消費者將逐步深入每個目錄的水平。在這種情況下，它會嘗試使用「ls -al」加載文件夾中的文件和目錄。命令。
