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？
