如果通过java socket中的多个客户端发送数据，如何监听端口

Question

我有多个客户端将数据发送到相同的预定义IP地址和端口号。我正在尝试 java socket 。我有一个消费者代码（服务器）接受来自多个客户端的数据。但我的消费者代码只收听第一个客户数据。它忽略了第二个。

服务器： -

public class consumer {

    public static void main(String[] args) throws IOException {
        ServerSocket serverScoket=new ServerSocket(3333,10);        
        Socket socket=serverScoket.accept();  
        DataInputStream din=new DataInputStream(socket.getInputStream());     
        while(true){  
            String str="";
            str=din.readUTF();  
        if(str.length()>0)
        System.out.println("client says: "+str);  
        }  
    }
}

第一位客户： -

public class uploader1 {

    public static void main(String[] args) throws UnknownHostException, IOException, InterruptedException {
        // TODO Auto-generated method stub
        Socket s=new Socket("localhost",3333);  
        DataOutputStream dout=new DataOutputStream(s.getOutputStream());  
        int i = 0;
        while(i++<15){          
            Thread.sleep(1000); 
            dout.writeUTF("u1 "+i);  
            dout.flush();  
        }  

        dout.close();  
        s.close(); 
    }
}

第二位客户： -

public class uploader2 {

    public static void main(String[] args) throws UnknownHostException, IOException, InterruptedException {
        // TODO Auto-generated method stub
        Socket s=new Socket("localhost",3333);  
        DataOutputStream dout=new DataOutputStream(s.getOutputStream());   
        int i = 0;
        while(i++<15){          
            Thread.sleep(1000);
            dout.writeUTF("u2 "+i);  
            dout.flush();   
        }         
        dout.close();  
        s.close(); 
    }
}

如果执行序列是consumer，uploader1，uploader2，那么它就像这样打印

client says: u1 1
client says: u1 2
client says: u1 3
client says: u1 4
client says: u1 5
client says: u1 6
client says: u1 7
client says: u1 8
client says: u1 9
client says: u1 10
client says: u1 11
client says: u1 12
client says: u1 13
client says: u1 14
client says: u1 15

我是否可以通过Java套接字编程实现它，或者我需要找到其他方法。请建议。
