Question

您好我有一个客户端服务器程序，服务器端工作，而客户端有一些问题。客户端连接后打印出一条消息，但在一些用户输入（尚未使用）后，我收到此错误。服务器打印出一个带有行号和序列号的文本文件（seq nums还不是很正确），并且应该将行号，序列号和文本行发送给客户端。

服务器：

public class STSServer {

/**
 * @param args the command line arguments
 */
public static void main(String argv[]) throws Exception 
{
    String startLineFromClient;
    String endLineFromClient;
    String stringLineNumber;
    String stringSeqNumber;
    String test = "hello";
    int convertStart;
    int convertEnd;
    int subtractStartEnd;
    int temp;
    int byteTransfer;
    int lineNumber = 0;
    int sequenceNumber;



    ServerSocket welcomeSocket =  new ServerSocket(6789);
    Socket connectionSocket =  welcomeSocket.accept();
    BufferedReader inFromClient =
            new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));
    DataOutputStream outToClient = 
            new DataOutputStream(connectionSocket.getOutputStream());

      try{
            File myFile = new File("alice.txt");
            FileReader fileReader = new FileReader(myFile);
            BufferedReader bufferedReader = new BufferedReader(fileReader);
            StringBuffer stringBuffer = new StringBuffer();
            String line;

            startLineFromClient = inFromClient.readLine();
            endLineFromClient = inFromClient.readLine();

             convertStart = Integer.parseInt(startLineFromClient);
             convertEnd = Integer.parseInt(endLineFromClient);

            while((line = bufferedReader.readLine()) != null)
            {   


                sequenceNumber = line.length();

                System.out.print(lineNumber);
                stringLineNumber = Integer.toString(lineNumber);
                outToClient.writeBytes(stringLineNumber);

                System.out.print(" ");

                System.out.print(sequenceNumber);
                stringSeqNumber = Integer.toString(sequenceNumber);
                outToClient.writeBytes(stringSeqNumber);


                System.out.print(" ");

                System.out.print(line);
                outToClient.writeBytes(line);
                System.out.println("");

                lineNumber++;

               //stringLineNumber = Integer.toString(lineNumber);
               //stringSeqNumber = Integer.toString(sequenceNumber);*/
               // outToClient.writeBytes(test);

            }
            fileReader.close(); 
        }
      catch(IOException e)
        {
            e.printStackTrace();
        }

}

}

客户端：公共类STSClient {

public static void main(String argv[])throws Exception
{
    String startLine;
    String endLine;
    String lineNumber;
    String seqNumber;
    String line;

    BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in));
    Socket clientSocket = new Socket("localhost", 6789);
    DataOutputStream outToServer =
            new DataOutputStream(clientSocket.getOutputStream());
    BufferedReader inFromServer = 
            new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));

     while (true)
     {
        System.out.println("+++++++++++++++++++++++++++++++++++++++++++++");
        System.out.println("+++++++++++++++ Simple TCP Service (STS)+++++");
        System.out.println("+++++++++++++++++++++++++++++++++++++++++++++");
        System.out.println("Command allowed by the server for this client:");
        System.out.println("download [starting line #] [ending line #]");
        System.out.print("Command: ");
        startLine = inFromUser.readLine();
        endLine = inFromUser.readLine(); 

        outToServer.writeBytes(startLine + '\n');
        outToServer.writeBytes(endLine + '\n');


        lineNumber = inFromServer.readLine();
        seqNumber = inFromServer.readLine();
        line = inFromServer.readLine();

         System.out.print(lineNumber);
         System.out.print(seqNumber);
         System.out.print(line);
         System.out.println("");
     }  
}

}

Answer 1

您的客户正在读行。
您的服务器没有发送线路。
您的服务器在不关闭套接字的情况下退出，而套接字会在Windows上重置。
您的客户仍然停留在等待线路终结器的第一个readLine()。
改为重置连接。

解决方案：发送线路，不要在不关闭套接字的情况下退出。

Java客户端/服务器错误：连接重置
