Java TCP Socket发送字节数组(Java TCP Socket send byte array)

 我正在尝试使用Java TCP套接字构建文件服务器。 当我尝试发送文件超过几KB时，我不断收到错误消息。 错误如下： 
 
Exception in thread "main" java.net.SocketException: Connection reset by peer: socket write error
at java.net.SocketOutputStream.socketWrite0(Native Method)
at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92)
at java.net.SocketOutputStream.write(SocketOutputStream.java:136)
at fileServer.TCPServer.main(TCPServer.java:193)
 
 我正在创建这样的输出流： 
 
OutputStream output = clientSocket.getOutputStream()
 
 错误来自这一行： output.write(sendData, 0, sendData.length) 
 
 其中，sendData是一个字节数组，我手工制作一个与协议一致的“协议”，该协议是28个字节的字节以及文件。 它错误出来的文件大约是780kB，其中一个2kB文件完美。 有任何想法吗？ 
 
 编辑：一些添加我如何制作套接字的上下文。 
 
            Socket clientSocket = listenSocket.accept();
        System.out.println("server is listening...");

        DataInputStream input = new DataInputStream(clientSocket.getInputStream());
        OutputStream output = clientSocket.getOutputStream();



        //receive the request packet
        //int nb = input.readInt();
        System.out.println("Read Length " + "28");
        byte[] sentence = new byte[28];
        for(int i=0; i<28; i++){
            sentence[i] = input.readByte();
        }
 
 这就是我发送数据的方式：sendData是我构建发送的字节数组tArray是我正应对sendData发送的文件的字节数组 
 
for(int i = 0; i<filSize; i++){
   //loads into the packet being built
   //needed to minus 36 since all the header info
   endData[i+36] = tArray[i];
}
System.out.println("send packet size: " + sendData.length);

System.out.print(sendData);
System.out.println("File size is: " + filSize);
int sendDataLength = sendData.length;
try{
    output.write(sendData, 0, sendDataLength);
}catch (IOException e){
    System.out.println("Error: " + e.getMessage());
}
clientSocket.close();
 
 编辑2：我用了一个try catch，现在得到这个错误：软件导致连接中止：套接字写入错误 

I'm trying to build a file server using Java TCP sockets. I keep getting an error when I try to send a file over a few KB. The error is as follows:
 
Exception in thread "main" java.net.SocketException: Connection reset by peer: socket write error
at java.net.SocketOutputStream.socketWrite0(Native Method)
at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92)
at java.net.SocketOutputStream.write(SocketOutputStream.java:136)
at fileServer.TCPServer.main(TCPServer.java:193)
 
I am creating the output stream like this:
 
OutputStream output = clientSocket.getOutputStream()
 
And the error originates from this line: output.write(sendData, 0, sendData.length)
 
Where sendData is a byte array I hand make to an agreed upon 'protocol' that is 28 header bytes along with the file. The file it is erroring out on is about 780kB where a 2kB file works perfect. Any ideas?
 
EDIT: some added context of how I'm making the socket.
 
            Socket clientSocket = listenSocket.accept();
        System.out.println("server is listening...");

        DataInputStream input = new DataInputStream(clientSocket.getInputStream());
        OutputStream output = clientSocket.getOutputStream();



        //receive the request packet
        //int nb = input.readInt();
        System.out.println("Read Length " + "28");
        byte[] sentence = new byte[28];
        for(int i=0; i<28; i++){
            sentence[i] = input.readByte();
        }
 
And this is how I'm sending the data: sendData is the bytearray I built to send tArray is the array of bytes of the file that I'm coping into sendData to send
 
for(int i = 0; i<filSize; i++){
   //loads into the packet being built
   //needed to minus 36 since all the header info
   endData[i+36] = tArray[i];
}
System.out.println("send packet size: " + sendData.length);

System.out.print(sendData);
System.out.println("File size is: " + filSize);
int sendDataLength = sendData.length;
try{
    output.write(sendData, 0, sendDataLength);
}catch (IOException e){
    System.out.println("Error: " + e.getMessage());
}
clientSocket.close();
 
EDIT 2: I used a try catch and got this error now: Software caused connection abort: socket write error
