FTPClient.listFiles不起作用

问题描述

  FTPFile [] subFiles = ftpClient .listFiles（ 目录）; 
  

虽然目录是有效的，但是在调用listFiles时代码被卡住了，可能是什么原因。 ？另外我想提一下，访问同一个FTP服务器的单独的netbeans项目可以使用相同的代码正常工作，但是maven项目存在这个问题。
请帮助。

解决方案

尝试使用。我假设你正在使用最新的图书馆（你没有写过你正在使用的库）。

接下来的方法，尝试更改文件列表布局。公共资源库使用自动检测，但在某些情况下，这不起作用。您可以更改（和测试）另一个文件列表布局，如下所示：

  FTPClientConfig配置=新FTPClientConfig（FTPClientConfig.TEST_YOURSELF）; 
 
 FTPClient yourClient = FTPClient（...）; 
 client.configure（conf）; 
  

I am trying to list all the files under a specific directory in a ftp server.

FTPFile[] subFiles = ftpClient.listFiles("directory");

Although the directory is a valid one , but the code gets stuck while calling listFiles , what may be the reason. ? Further i would like to mention that a seperate netbeans project accessing the same FTP server is working fine with the same code , but a maven project is having the problem.please help.

解决方案

Try to use passive mode. I assume that you are using the newest commons net library (you didn't write which lib you are using).

---

Next approach, try to change the file list layout. The commons lib uses auto-detection but in some cases this doesn't work. You can change (and test) another file list layout as followed:

FTPClientConfig configuration = new FTPClientConfig(FTPClientConfig.TEST_YOURSELF);

FTPClient yourClient = FTPClient(...);
client.configure(conf);
