服务端课键盘录入，客户端也收的到，但是客户端不可以键盘录入，为什么啊，我知道应该是阻塞方法的原因，但是我不知道在哪里，怎么改，求大侠帮忙啊

用线程控制就可以实现了：

客户端：
import java.io.IOException;
import java.net.Socket;


public class MainClient
{
public static void main(String [] args) throws Exception,IOException
{

Socket socket = new Socket("127.0.0.1",4000);

new ClientInputThread(socket).start();
new ClientOutputThread(socket).start();

}
}





客户端输入：
import java.io.IOException;
import java.io.InputStream;
import java.net.Socket;

public class ClientInputThread extends Thread

{
private Socket socket;
public ClientInputThread(Socket socket)
{
this.socket = socket;
}
public void run()
{
try {
InputStream is = socket.getInputStream();

while(true)
{
byte [] buffer = new byte[1024];
int length = is.read(buffer);
String str = new String(buffer,0,length);
System.out.println(str);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}




客户端输出线：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.Socket;

public class ClientOutputThread extends Thread
{
private Socket socket;
public ClientOutputThread(Socket socket)
{
this.socket = socket;
}
public void run()
{
try {
OutputStream os = socket.getOutputStream();
while(true)
{
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String line = reader.readLine();
os.write(line.getBytes());
}
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}






服务器：

import java.net.ServerSocket;
import java.net.Socket;

public class MainServer
{


public static void main(String [] args) throws Exception
{



ServerSocket serverSocket = new ServerSocket(4000);
while(true)
{
Socket socket = serverSocket.accept();
new ServerInputThread(socket).start();
new ServerOutputThread(socket).start();
}
}

}



服务器输入：
import java.io.IOException;
import java.io.InputStream;
import java.net.Socket;

public class ServerInputThread extends Thread
{
private Socket socket;
public ServerInputThread(Socket socket)
{
this.socket = socket;
}
public void run()
{

try {
InputStream is = socket.getInputStream();
while(true)
{
byte[] buffer = new byte[1024];
int length = is.read(buffer);
String str = new String(buffer,0,length);
System.out.println(str);
}
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}





服务器输出：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.Socket;


public class ServerOutputThread extends Thread
{
private Socket socket;

public ServerOutputThread(Socket socket)
{
this.socket = socket;
}
public void run()
{
try
{
OutputStream os = socket.getOutputStream();
while(true)
{
BufferedReader reader = new BufferedReader (new InputStreamReader(System.in));
String line = reader.readLine();
os.write(line.getBytes());
}
}
catch(IOException e)
{
e.printStackTrace();
}
}
}

2 楼怎么运行呢

[aaaabbbccd9876]

[Quote=引用 4 楼 的回复:]
服务端先读后写 客户端先写后读 你的逻辑出错了
[/Quote]这个说法不对，我该了位置是这样的

//服务端
import java.net.*;
import java.io.*;
class fanserver1
{
    public static void main(String[] args)throws Exception 
    {
        ServerSocket ss = new ServerSocket(4444);
        Socket s = ss.accept();
        BufferedReader br = 
            new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bwout = 
            new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
        BufferedReader brin = 
            new BufferedReader(new InputStreamReader(s.getInputStream()));
        String str = null;
		while((str=brin.readLine())!=null){
            System.out.println(str);
        }
		String line=null; 
        while((line=br.readLine())!=null){
        //    System.out.println(line);
            bwout.write(line);
            bwout.newLine();
            bwout.flush();
        }
        s.shutdownOutput();
       
      
        
        
    }
}
//客户端

class fanclient1 
{
    public static void main(String[] args)throws Exception
    {
        Socket s = new Socket("192.168.30.129",4444);
        BufferedReader br = 
            new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bwout = 
            new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
        BufferedReader brin = 
            new BufferedReader(new InputStreamReader(s.getInputStream()));
             
        String str = null;
        while((str=br.readLine())!=null){
            
            bwout.write(str);
            bwout.newLine();
            bwout.flush();
        //    String line = brin.readLine();

        }
    //    s.shutdownOutput();
       String line = null;
        while((line=brin.readLine())!=null){
            System.out.println(line);
        }
    //    String line = brin.readLine();
    //    System.out.println(line);
        
    }
}

客户端发信息，服务端接收的到，但是服务端就不能录入键盘

[rockets311]

建议用线程控制。。。

[z744489075]

服务端先的接受客服端的数据才能往会写 逻辑出错了
