Java FTP上载中出错“；553无法创建文件"；

我使用上述代码在服务器位置192.168.0.210上传一个名为“data.doc”的文件。 我的服务器的目标位置是fileserver/filesbackup/Emac/

---

尽管服务器连接成功，但我最终收到错误“553无法创建文件”。我怀疑我以错误的方式给出了目标格式。请告诉我如何解决此问题？

问题是您试图将文件上载到目录。您应该指定目标文件名，而不是目标目录

当您在另一个FTP客户端中尝试相同的方法时，它是否有效

[更新]

下面是一些（未经测试，因为我没有FTP服务器）代码，它们以更短的形式更好地处理错误

import org.apache.commons.net.ftp.FTPClient;

import org.apache.commons.net.ftp.FTPReply;

import org.apache.commons.net.ftp.FTPFile;
import java.io.*;

public class FTPUpload{


public static boolean uploadfile(String server,String username,String Password,String source_file_path,String dest_dir){

FTPClient ftp=new FTPClient();

try {

 int reply;


 ftp.connect(server);

   ftp.login(username, Password);
 System.out.println("Connected to " + server + ".");

 System.out.print(ftp.getReplyString());


 reply = ftp.getReplyCode();


 if(!FTPReply.isPositiveCompletion(reply)) {

ftp.disconnect();

System.err.println("FTP server refused connection.");

return false;

 }

 System.out.println("FTP server connected.");

                    InputStream input= new FileInputStream(source_file_path);


 ftp.storeFile(dest_dir, input);

  System.out.println( ftp.getReplyString() );

                    input.close();

                    ftp.logout();

 } catch(Exception e) {

                    System.out.println("err");

   e.printStackTrace();

                    return false;

  } finally {

   if(ftp.isConnected()) {

    try {

    ftp.disconnect();

    } catch(Exception ioe) {

    }

   }

  }

   return true;

   }



  public static void main(String[] args) {

   FTPUpload upload = new FTPUpload();

   try {

    upload.uploadfile("192.168.0.210","muruganp","vm4snk","/home/media/Desktop/FTP Upload/data.doc","/fileserver/filesbackup/Emac/");

   } catch (Exception e) {

   e.printStackTrace();

  }

  }

   }

哇！谢谢将目标位置更改为/fileserver/filebackup/Emac/data.doc:）是否有可能在文件名中插入字符串。因为程序使用的文件名将是在我的程序中用作字符串的日期。

“Output/”+date+“\u RB”+”.zip“

，其中日期是字符串。。。我怎样才能在上述程序的源代码和目标代码中使用它呢。用于形成文件名的表达式看起来已经很好了。是的。我会尽力让你知道的
