我正在构建一个简单的Java服务器，该服务器使用两个ServerSocket实例同时在两个端口上同时侦听客户端请求。这是服务器的代码：

import java.io.PrintWriter;

import java.io.OutputStream;

import java.net.ServerSocket;

import java.net.Socket;

class Socket1 implements Runnable

{

public void run()

{

try

{

ServerSocket serverSock=new ServerSocket(5000);

while(true)

{

Socket sock=serverSock.accept();

PrintWriter writer=new PrintWriter(sock.getOutputStream());

String text="Welcome to Port 5000";

writer.println(text);

}

}

catch(Exception e)

{

System.out.println("Error");

}

}

}

class Socket2 implements Runnable

{

public void run()

{

try

{

ServerSocket serverSock=new ServerSocket(3000);

while(true)

{

Socket sock=serverSock.accept();

PrintWriter writer=new PrintWriter(sock.getOutputStream());

String text="Welcome to Port 3000";

writer.println(text);

}

}

catch(Exception e)

{

System.out.println("Error");

}

}

}

public class Server

{

public static void main(String[] args)

{

Socket1 s1=new Socket1();

Socket2 s2=new Socket2();

Thread t1=new Thread(s1);

Thread t2=new Thread(s2);

t1.start();

t2.start();

}

}

现在为Client1编码：

import java.io.InputStreamReader;

import java.io.BufferedReader;

import java.net.Socket;

public class Client1

{

public static void main(String[] args)

{

try

{

Socket s=new Socket("127.0.0.1", 5000);

InputStreamReader streamReader=new InputStreamReader(s.getInputStream());

BufferedReader reader=new BufferedReader(streamReader);

String text=reader.readLine();

System.out.println(text);

reader.close();

}

catch(Exception e)

{

System.out.println("Error");

}

}

}

Client2包含与Client1相同的代码，唯一的区别是它尝试连接到端口3000。现在，我首先使用命令提示符执行Server.java。服务器阻塞时，我打开两个单独的命令提示符，并在一个命令提示符下执行Client1.java，在另一个命令提示符下执行Client2.java。但是，两个客户端都进入阻塞状态，但我没有任何输出。知道如何解决这个问题吗？
