java - 上传多个文件到服务器

Question

将多个文件上传到服务器。这是客户端机器的代码:

void SendFile() throws Exception
{        

    String path;
    System.out.print("Enter File Path :");
    path=br.readLine();

    File f=new File(path);
    File files[]=f.listFiles();
    String fileName;

      for(File file:files)
      {
         if(file.isFile())

         {

             fileName=file.getName();
             dout.writeUTF(fileName);


    System.out.println("Sending File ..."+fileName);
    FileInputStream fin=new FileInputStream(f);
    int ch;
    do
    {
        ch=fin.read();
        dout.writeUTF(String.valueOf(ch));
    }
    while(ch!=-1);
    fin.close();
    System.out.println(din.readUTF());

    }  

 }
}

但是发送单个文件后程序会产生错误:

Exception in thread "main" java.io.FileNotFoundException: /home/bdi-user/Desktop/files (Is a directory)

Answer 1

不要从目录 f 中读取，而是从您称为 file 的文件中读取。

FileInputStream fin=new FileInputStream(file);
