Apache的駱駝FTP越來越無法檢索文件：參數】remotefile錯誤

Question

我試圖檢索使用駱駝FTP組件文件（駱駝2.19.0）：

from("ftp://my.host.com:21/my/relative/directory?download=true&stepwise=false&delete=false") 

駱駝是連接和正確的目錄列表中的文件，但是當它去處理它們，它會因每個文件以下異常：

org.apache.camel.component.file.GenericFileOperationFailedException: Cannot retrieve file: RemoteFile[my/relative/directory/file1.txt] from: ftp://my.host.com:21/my/relative/directory?delete=false&download=true&stepwise=false

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) 
    at java.lang.Thread.run(Thread.java:748) 

從跟蹤日誌，我可以看到駱駝是正確列出該目錄中的文件：

[TRACE] 2017-09-05 11:40:49,438 org.apache.camel.component.file.remote.FtpConsumer - Polling directory: my/relative/directory 
[TRACE] 2017-09-05 11:40:51,748 org.apache.camel.component.file.remote.FtpOperations - listFiles(my/relative/directory)

[TRACE] 2017-09-05 11:40:58,657 org.apache.camel.component.file.remote.FtpConsumer - FtpFile[name=/absolute/path/to/directory/file2.txt, dir=false, file=true] 
[TRACE] 2017-09-05 11:40:58,657 org.apache.camel.component.file.remote.FtpConsumer - FtpFile[name=/absolute/path/to/directory/file3.txt, dir=false, file=true] 

當駱駝試圖然而來處理每個文件，這似乎是前面加上相對目錄到絕對目錄和沒有找到所得到的亂碼路徑：

[TRACE] 2017-09-05 11:40:59,417 org.apache.camel.component.file.remote.FtpConsumer - Processing file: RemoteFile[absolute/path/to/directory/file1.txt]

[TRACE] 2017-09-05 11:40:59,418 org.apache.camel.component.file.remote.FtpOperations - retrieveFile(my/relative/directory//absolute/path/to/directory/file1.txt) 
[TRACE] 2017-09-05 11:40:59,418 org.apache.camel.component.file.remote.FtpOperations - Client retrieveFile: my/relative/directory//absolute/path/to/directory/file1.txt 
[WARN ] 2017-09-05 11:40:59,518 org.apache.camel.component.file.remote.FtpConsumer - Error processing file RemoteFile[absolute/path/to/directory/file1.txt] due to Cannot retrieve file: RemoteFile[absolute/path/to/directory/file1.txt] from: ftp://my.host.com:21/my/relative/directory?delete=false&download=true&stepwise=false 

由FTPComponent構成該路徑在日誌中不正確：

檢索文件： 我/相對/目錄//絕對/路徑/到/目錄/ FILE1.TXT

我調試的駱駝FTP消費者，它看起來像on line 238 is where the relative path is getting prepended to the absolute path

有趣的是，the SFTP component is doing the same thing但它是工作，因爲RemoteFileOperations<ChannelSftp.LsEntry>不設置文件名作爲絕對路徑，但RemoteFileOperations<FTPFile>一樣。

有沒有人有任何建議來解決這個問題，讓FTP Conponent消耗這些文件？還是我做錯了什麼？

我用駱駝2.19.0

Answer 1

默認情況下，駱駝將轉到\首頁{用戶名} \目錄。
如果您的文件保存在相對路徑下，則只需將目錄路徑設置爲\ abc-any-path \ file.txt
如果您的文件保存在\ home {用戶名} \以外的任何路徑中，那麼你需要給
\ .. \ .. \ abc-any-absolute-path \ file.txt

駱駝不允許你直接輸入絕對路徑。希望這可以幫助！
