java实现J联机五子棋

在完成java单机五子棋后,我开始尝试写联机五子棋(局域网内,因为没有公网IP)。上次的五子棋写的很乱,全部写在一个类中,这次我采用面向对象的思想,把特定的功能和属性都写成一个类。代码分为两部分,客户端和服务端。客户端是用AWT写的,主要由一个五子棋面板和一个功能键面板构成。网络通信使用的是TCP,通过序列化和反序列化完成消息的读和写。运行的时候先运行服务端程序,接着运行两个客户端。代码放在了文章的最后
下面是客户端运行的效果:

这里是代码包的结构:

接着我来依次说下这些类所完成的功能
Media包
Media包:主要是放了五子棋的背景图片和播放音乐的类以及音乐内容
播放音乐这个类是我从室友那拿的,所以我也不是很懂,瞄了一眼是用Applet完成的,只能处理.wav后缀的音乐
Net包
Net包:包含两个类,细心的小伙伴应该注意到客户端是没有主方法的。客户端中其实是包含与服务端进行通信的socket的,其中包含一些读和写的方法。服务端我采用的是线程池的方法来处理客户端的请求(线程池这部分我也不是特别了解,用起来和多线程感觉差不多)。
View包
View包:包含四个类,分别是ChessBoard,ChessPanel,Pieces和WhoWin 类
ChessBoard是一个包含Main方法的JFrame,命令面板和棋盘面板都是添加到这个JFrame中的。
ChessPanel是一个棋盘面板,里面完成了如:画19*19的棋盘线条,加载背景图片,不停的接收来自服务端的消息并处理(把棋子加到面板),处理每次点击后添加棋子到面板并发送棋子到服务器,判断胜负并且给出提示消息。
Pieces是一个棋子,其中有包含如颜色,棋子半径,棋子位置和命令(和前面的命令面板配合使用,默认是发送)等属性。
WhoWin就是五子棋中判断谁输谁赢的部分。每下一步就需要判断。
播放音乐的类:
