Cocos2dX通过Java服务器向Unity传输数据三

前端之家收集整理的这篇文章主要介绍了Cocos2dX通过Java服务器向Unity传输数据三前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

Java服务器代码如下:

package com.insect.server;

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

public class ServerThread extends Thread{
	
	boolean flag=false;
	ServerSocket ss;
	
	public void run(){
		try {
			ss=new ServerSocket(59422);
			System.out.println("Server Listening on 59422...");
			flag=true;
		} catch (Exception e) {
			// TODO: handle exception
			e.printStackTrace();
		}
		
		while(flag){
			try {
				Socket sc=ss.accept();
				System.out.println(sc.getInetAddress()+" connect...");
				ServerAgent.flag=true;
				new ServerAgent(this,sc).start();
			} catch (Exception e) {
				// TODO: handle exception
			}
		}
	}
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		new ServerThread().start(); 
		
	}
}

	}
