java - 如何使用套接字接收和存储文件

我正在尝试使用套接字发送文件，但是当我收到文件时，无法存储它。
调试器显示，代码停止在


  bytesRead =
                                          is.read（mybytearray，current，（mybytearray.length-current））;


并没有任何反应。


  bytesRead = is.read（mybytearray，0，mybytearray.length）;
  -等于17

public static void main(String[] args) throws IOException {
            FileOutputStream fileOutputStream = null;
            BufferedOutputStream bufferedOutputStream = null;
            Socket socket = null;
            ServerSocket serverSocket = null;
            try {
                serverSocket = new ServerSocket(SOCKET_PORT);
                while (true) {
                    System.out.println("Waiting...");
                    try {
                        socket = serverSocket.accept();
                        System.out.println("Accepted connection : " + socket);
                        int bytesRead;
                        int current = 0;
                        byte[] mybytearray = new byte[FILE_SIZE];
                        InputStream is = socket.getInputStream();
                        fileOutputStream = new FileOutputStream(FILE_TO_RECEIVED);
                        bufferedOutputStream = new BufferedOutputStream(bufferedOutputStream);
                        bytesRead = is.read(mybytearray, 0, mybytearray.length);
                        current = bytesRead;

                        do {
                            bytesRead =
                                    is.read(mybytearray, current, (mybytearray.length - current));
                            if (bytesRead >= 0) current += bytesRead;
                        } while (bytesRead > -1);

                        bufferedOutputStream.write(mybytearray, 0, current);
                        bufferedOutputStream.flush();
                        System.out.println("File " + FILE_TO_RECEIVED
                                + " recieved (" + current + " bytes read)");


                    } finally {
                        if (fileOutputStream != null) fileOutputStream.close();
                        if (bufferedOutputStream != null) bufferedOutputStream.close();
                        if (socket != null) socket.close();
                    }
                }
            } finally {
                if (serverSocket != null) serverSocket.close();
            }
        }

最佳答案

您可以尝试直接写入OutputStream，例如将您的while循环更改为

while ((bytesRead = in.read(mybytearray)) > 0) {
    fileOutputStream.write(mybytearray, 0, bytesRead);
}
