我正在用Java制作游戏。我被困了，因为我不知道如何处理阻塞套接字，因为我想拥有服务器gui。我在客户端也有问题，因为它阻碍了游戏的核心。服务器socket.accept()是问题1，而客户端我不知道。我到处搜索，但我没有找到答案。我只发现了像＃34; Make thread来处理socket＆＃34;。我试过这个。
客户端
package com.sec.network;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Random;
import java.util.concurrent.ThreadLocalRandom;
public class Clinetmulti {
public static boolean running = false;
public static boolean delayed = false;
public static void main(String args[]) throws Exception {
String[] namesList = new String[4];
namesList[0] = "Unknown";
namesList[1] = "Tom";
namesList[2] = "Ronald";
namesList[3] = "Lamkas";
String inmess = "NoMess";
String outmess = "NoMess";
boolean connected = false;
int random1 = ThreadLocalRandom.current().nextInt(1, 3 + 1);
String playername = namesList[random1];
Socket sk=new Socket("hidden" , 5000);
BufferedReader sin=new BufferedReader(new InputStreamReader(sk.getInputStream()));
PrintStream sout=new PrintStream(sk.getOutputStream());
String s;
String oldinmess = "NoMess";
running = true;
System.out.println("Client started...");
while (true) {
if(delayed == true) {
//Read
if(sin.ready()) {
if(!sin.readLine().equals(oldinmess)) {
inmess = sin.readLine();
System.out.print("Server : " + inmess + "\n");
oldinmess = inmess;
}
}
//Check Messages
if(connected == false) {
if(inmess.equals(playername + "> " + "Connected")) {
connected = true;
}
}
//Check States
if(connected == false) {
outmess = "Request connect";
}
if(inmess.equals("Server stop")) {
outmess = "Stopping...";
break;
}
//Post
if(!outmess.equals("NoMess")) {
sout.println(playername + "> " + outmess);
sout.flush();
System.out.println("Client: " + playername + "> " + outmess);
}
//ClearMessageProccess
inmess = "NoMess";
outmess = "NoMess";
}
}
sk.close();
sin.close();
sout.close();

答案 0 :(得分：0)
您需要实现多线程，1个线程接受来自客户端的连接，1个线程为连接到服务器的每个客户端启动。
以下是如何操作的示例：
public class Server {
private ServerSocket server;
public Server(int port) {
server = new ServerSocket(port);
}
public void listenForConnections() {
while (true) {
// Accept clients
Client client = new Client(server.accept());
// Create and start new thread when client connects
new Thread(client).start();
}
}
}
public class Client implements Runnable {
private Socket socket;
public Client(Socket socket) {
this.socket = socket;
}
public void run() {
while (true) {
// Do something
}
}
}
