Socket 编程小问题--PrintWriter的flush方法只能刷新一次

[ZHFIFA]

我正在做一个简单的C/S小程序。客户端发消息，服务端接受。源代码如下：
客户端

import java.net.*;
import java.io.*;

public class P2PClientManager {
    private final int PortNum=4700;
    private final String UserHint="Please input your server address or name:";
    private final String ConnectionSuccess="Server connected successfully!\nPlease enter your message:";
    private final String EndMessageTag="end";
    
    public void StartClient() throws IOException
    {
        BufferedReader serverAddressBuffer = new BufferedReader(new InputStreamReader(System.in)); 
        System.out.println(UserHint); 
        String serverAddress= serverAddressBuffer.readLine().toUpperCase().trim();
        try
        {
            Socket clientSocket = new Socket(serverAddress, PortNum);
            if(clientSocket.isConnected())
            {
                System.out.println(ConnectionSuccess);
                
                BufferedReader userClientInputBuffer=new BufferedReader(new InputStreamReader(System.in)); 
                
                PrintWriter outStream = new PrintWriter (clientSocket.getOutputStream());    
                String userInput=userClientInputBuffer.readLine();
                
                while(!userInput.toLowerCase().equals(EndMessageTag))
                {
                    outStream.println(userInput);
                    outStream.flush();

                    userInput=userClientInputBuffer.readLine();
                    
                }
                
                
                outStream.close();
                clientSocket.close();
            }
        }
        catch(Exception ex)
        {
            System.out.println("Error:"+ex);
        }
        
    }
}

服务端：

import java.net.*;
import java.io.*;

public class P2PServerManager {
    private final int PortNum=4700;
    
    public void StartServer() throws IOException
    {
        ServerSocket serverSocket = new ServerSocket(PortNum);
        
        while (true) 
        {
            Socket socketClient = serverSocket.accept();
            System.out.println(socketClient.getInetAddress());
            BufferedReader clientSendContent = new BufferedReader(new InputStreamReader(
                    socketClient.getInputStream()));        
            
            System.out.println(clientSendContent.readLine());
            
        }
    }
}

问题：现在程序运行后，在客户端输入消息，服务端可以接收，但是只能接收一次，当我继续在客户端输入文字的时候，服务端却不能显示我的输入数据。。。

请问各位大虾，我改如何改。十分感谢

Socket socketClient = serverSocket.accept();

执行到accept程序会在这里等待吧...所以你移到while外面去...

[waison0918]

System.out.println(clientSendContent.readLine());

因为你这里只从输入流中读出其中一行,应该像客户端一样设定一个循环来重复读入啊
