我正在尝试使用socket从客户端向服务器发送多个文件 但是当我点击上传按钮时，它只添加一个文件 然后第二次点击添加第二次。这是我的代码：
客户端
void SendFile (String St, String Na) throws IOException{
Socket sock = new Socket("127.0.0.1", 1112);
//ObjectOutputStream out = new ObjectOutputStream(sock.getOutputStream());
//outStream.writeObject("test message #");
//outStream.flush();
//FileInputStream Fi = null;
try {
// TODO add your handling code here:
FileInputStream Fi = new FileInputStream(St);
byte [] Buffer = new byte[Fi.available()];
Fi.read(Buffer);
ObjectOutputStream out = new ObjectOutputStream(sock.getOutputStream());
out.writeObject(Buffer);
out.flush();
out.close();
//outStream.writeObject(Buffer);
write.println("Send:File: " + Na);
write.flush();
} catch (FileNotFoundException ex) {
Logger.getLogger(Add_Book.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(Add_Book.class.getName()).log(Level.SEVERE, null, ex);
}
catch (Exception ex)
{
System.out.println("error connecting to server");
}
sock.close();
}
`
通话方式：
SendFile(CoverPath,CoverName);
SendFile(BookPath,BookName);
服务器

ObjectOutputStream Oos = new ObjectOutputStream(clientSocket.getOutputStream());
is = clientSocket.getInputStream();
Thread listener = new Thread(new UploadHandler(clientSocket));
listener.start();
TextArea.append("Request upload. \n");
ss = clientSocket;
}
}
catch (Exception ex)

TextArea.append("Error making a connection. \n");
}
}
}
public class UploadHandler implements Runnable

public UploadHandler(Socket clientSocket)

inputS = new ObjectInputStream(sock.getInputStream());
//input = new ObjectInputStream(sock.getInputStream());
}
catch (Exception ex)

}
