前言
最近刚好是期末，碰上Java实训，借此将之前写的在线聊天室搬出来，加上GUI（Swing），当成实训作品，记录一下这次实训的结果。
本篇文章主要叙述的是 ① 在线聊天室的代码结构； ② 将java文件打包成jar，再打包成exe文件； ③ 利用内网穿透技术实现与他人在线聊天。 附：在线聊天室实用socket通信，利用的网络协议是TCP，架构为C/S模式（Client-Server=>客户机-服务器）
功能设计
- 总体设计
- 详细设计 （1）聊天室服务器端
1）设置聊天室服务器的端口号，管理员昵称，启动服务器或者关闭服务器。 2）系统消息日志记录，管理员可发布系统消息给各在线用户。 3）管理员在线与聊天室在线用户进行群聊。 4）管理员可对在线用户列表中指定用户进行私聊请求，对方同意即可开始私聊。 5）管理员可对在线用户列表中指定用户进行踢出聊天室操作，并通知其他人。
（2）聊天室客户端
1）用户设置聊天室IP，端口号，用户昵称，连接服务器进入聊天室或退出聊天室。 2）系统消息通知，接受服务器端发布的消息，以及用户一些操作。 3）用户可与其他在线用户进行群聊。 4）用户可与指定用户列表中其他在线用户进行私聊请求，同意即可开始私聊。 5）用户可以屏蔽指定用户列表中的用户的群聊发言，屏蔽后即接受不到对方发言， 同时也可以选择取消屏蔽。
GUI画面展示
服务器端
- 启动界面
- 聊天界面
客户端
- 聊天界面
私聊窗口
- 被私聊者
- 聊天窗口
主要代码
客户端与服务器交互通过特定的指令与信息，客户端发送特定格式的指令和信息，服务器端接受到指令和信息，根据指令处理不同的业务请求，再将结果信息和响应指令发送到客户端，客户端根据不同指令将信息呈现到用户端GUI，或者改变客户端。
服务器端和用户端的主类都用到了内部类，因为毕竟容易获取主类的变量值，具体的类和方法介绍我就不仔细讲了，代码里面都有注释了，不懂看看注释，肯定不是因为我懒。
服务器端
- 服务器端主线程用来运行管理员操作的GUI界面
- 子线程运行ServerSocket服务
代码语言：javascript复制（1）创建ServerSocket对象，绑定监听端口。 （2）通过accept()方法监听客户端请求 （3）连接建立后，通过输入流读取客户端的数据 （4）通过输出流，向客户端回应信息 - 每有一个新的用户连接生成，会创建对应的子线程来处理对应用户端的需求，用户断开连接时，该线程也随之停止。

- 然后在打开的窗口里面这样操作
- 点击选择jar包运行的主类
- 选择要执行的是服务器端还是客户端
- 最后点击OK
- 然后构建环境生成jar包
- 在弹窗中选择Bulid
- 最后jar包就生成了，点开就能运行
- 服务器端和客户端生成jar包的操作差不多，就是选择主类的时候记得区别！
打包成exe文件
- 下载exe4j，自行百度下载咯
- 打开后，最好去网上找个注册码，不然之后每次打开exe文件都会有exe4j的广告弹窗！
提供一个注册码：L-g782dn2d-1f1yqxx1rv1sqd
- 开始，点击next
- 选择“JAR in EXE mode”，点击“Next”
- 给生成的exe应用取个名称，之后选择exe生成路径，点击“Next”
- 可选生成自定义图标，选择ico文件，没有就不选"Icon File"，最好不勾选“Allow only a single...”，因为这样才能在电脑运行多个客户端，选择了的话，生成的exe文件只能打开一个，当然服务器端可以点。
- 然后点击这个
- 在新窗口，继续点”Next"
- 选择勾上，然后继续“Next"
- VM Parameters要填的是: -Dappdir=${EXE4J_EXEDIR}
然后点击下一步
- 选择jdk版本
- 选择JRE
- 之后，一路点”Next"
- 最后生成exe，可以点击查看，或者去选择的生成目录查看exe文件
如何让其它电脑访问聊天室？
在线聊天室运用的是Socket通信，网络协议是TCP/IP，所以要如何让别的主机电脑访问聊天室呢
- 把聊天室服务器端放在有公网IP的云服务器或者主机上，开放特定的TCP端口号即可。
- 内网穿透技术，可以利用NAT穿透技术让外网的电脑能够访问处于内网的聊天室服务器，当然这里提供白嫖的内网穿透，毕竟只是同学之间玩玩这个聊天室而已。 点击去官网注册Sunny-Ngrok
注册完后登录后，点击开通隧道。
白嫖党，选择免费服务器。可能会有点卡，但是拿来使用聊天室够了
点击确定后，按图中说明填。
查看隧道，下载该软件，复制对应的TCP隧道ID
下载好软件后，点开目录，启动内网穿透
输入隧道id，回车启动即可
接着，打开聊天室的服务器，记住刚刚填写的本地的端口号，就是127.0.0.1:8888，这里需要一致，我们填写8888，启动服务。
在这个官网申请到的白嫖服务器的公网IP是64.69.43.237，端口号就是自己申请的，或者你可以查看运行的内网穿透窗口。
接着，启动客户端，来测试一下是否成功连接上服务器。
最后，连接成功，赶快把客户端发给同学，大家一起来聊天室聊天吧，哈哈哈
