我们希望用apache camel访问ebay商家集成平台（mip）。 它是一个“sftp服务器之类的”协议，它提供了一个你可以工作的目录结构。
因此，这是使用Apache Camel处理目录的一个主要示例。
但我们遇到了错误，因为mip-interface没有显示（或拥有）技术“。”和“..”目录。
任何人都可以给我一个提示
提前致谢。

答案 0 :(得分：0)
OMG - 找到了简单的解决方案：
设置 stepwise = false 将解决问题。
为什么呢？看了一下SftpConsumer.doPollDirectory（）后，我找到了一个不错的IF-THEN-ELSE块：
if (isStepwise()) {
files = operations.listFiles();
} else {
files = operations.listFiles(dir);
}
如果stepwise设置为false，则使用者将逐步执行每个目录级别。在这种情况下，它尝试使用＆＃34; ls -al。＆＃34;在文件夹中加载文件和目录。命令。
