前言
最近剛好是期末，碰上Java實訓，藉此將之前寫的在線聊天室搬出來，加上GUI（Swing），當成實訓作品，記錄一下這次實訓的結果。
本篇文章主要敘述的是
① 在線聊天室的代碼結構；
② 將java文件打包成jar，再打包成exe文件；
③ 利用內網穿透技術實現與他人在線聊天。附：在線聊天室實用socket通信，利用的網絡協議是TCP，架構爲C/S模式（Client-Server=>客戶機-服務器）
功能設計
- 總體設計
![總體設計]()
- 詳細設計
（1）聊天室服務器端
1）設置聊天室服務器的端口號，管理員暱稱，啓動服務器或者關閉服務器。
2）系統消息日誌記錄，管理員可發佈系統消息給各在線用戶。
3）管理員在線與聊天室在線用戶進行羣聊。
4）管理員可對在線用戶列表中指定用戶進行私聊請求，對方同意即可開始私聊。
5）管理員可對在線用戶列表中指定用戶進行踢出聊天室操作，並通知其他人。
（2）聊天室客戶端
1）用戶設置聊天室IP，端口號，用戶暱稱，連接服務器進入聊天室或退出聊天室。
2）系統消息通知，接受服務器端發佈的消息，以及用戶一些操作。
3）用戶可與其他在線用戶進行羣聊。
4）用戶可與指定用戶列表中其他在線用戶進行私聊請求，同意即可開始私聊。
5）用戶可以屏蔽指定用戶列表中的用戶的羣聊發言，屏蔽後即接受不到對方發言， 同時也可以選擇取消屏蔽。

主要代碼
客戶端與服務器交互通過特定的指令與信息，客戶端發送特定格式的指令和信息，服務器端接受到指令和信息，根據指令處理不同的業務請求，再將結果信息和響應指令發送到客戶端，客戶端根據不同指令將信息呈現到用戶端GUI，或者改變客戶端。
服務器端和用戶端的主類都用到了內部類，因爲畢竟容易獲取主類的變量值，具體的類和方法介紹我就不仔細講了，代碼裏面都有註釋了，不懂看看註釋，肯定不是因爲我懶。
服務器端
- 服務器端主線程用來運行管理員操作的GUI界面
- 子線程運行ServerSocket服務
（1）創建ServerSocket對象，綁定監聽端口。
（2）通過accept()方法監聽客戶端請求
（3）連接建立後，通過輸入流讀取客戶端的數據
（4）通過輸出流，向客戶端迴應信息
- 每有一個新的用戶連接生成，會創建對應的子線程來處理對應用戶端的需求，用戶斷開連接時，該線程也隨之停止。

打包成jar
- 項目結構
以idea爲演示
-
然後在打開的窗口裏面這樣操作
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
-
點擊選擇jar包運行的主類
![在這裏插入圖片描述]()
-
選擇要執行的是服務器端還是客戶端
![在這裏插入圖片描述]()
-
最後點擊OK
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
-
然後構建環境生成jar包
![在這裏插入圖片描述]()
-
在彈窗中選擇Bulid
![在這裏插入圖片描述]()
-
最後jar包就生成了，點開就能運行
![在這裏插入圖片描述]()
服務器端和客戶端生成jar包的操作差不多，就是選擇主類的時候記得區別！
打包成exe文件
- 下載exe4j，自行百度下載咯
![在這裏插入圖片描述]()
- 打開後，最好去網上找個註冊碼，不然之後每次打開exe文件都會有exe4j的廣告彈窗！
提供一個註冊碼：L-g782dn2d-1f1yqxx1rv1sqd
-
開始，點擊next
![在這裏插入圖片描述]()
-
選擇“JAR in EXE mode”，點擊“Next”
![在這裏插入圖片描述]()
-
給生成的exe應用取個名稱，之後選擇exe生成路徑，點擊“Next”
![在這裏插入圖片描述]()
-
可選生成自定義圖標，選擇ico文件，沒有就不選"Icon File"，最好不勾選“Allow only a single…”，因爲這樣才能在電腦運行多個客戶端，選擇了的話，生成的exe文件只能打開一個，當然服務器端可以點。
![在這裏插入圖片描述]()
-
然後點擊這個
![在這裏插入圖片描述]()
-
在新窗口，繼續點”Next"
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
-
選擇勾上，然後繼續“Next"
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
-
VM Parameters要填的是: -Dappdir=${EXE4J_EXEDIR}
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
然後點擊下一步
![在這裏插入圖片描述]()
-
選擇jdk版本
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
-
選擇JRE
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
-
之後，一路點”Next"
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()

最後生成exe，可以點擊查看，或者去選擇的生成目錄查看exe文件
如何讓其它電腦訪問聊天室？
在線聊天室運用的是Socket通信，網絡協議是TCP/IP，所以要如何讓別的主機電腦訪問聊天室呢
- 把聊天室服務器端放在有公網IP的雲服務器或者主機上，開放特定的TCP端口號即可。
- 內網穿透技術，可以利用NAT穿透技術讓外網的電腦能夠訪問處於內網的聊天室服務器，當然這裏提供白嫖的內網穿透，畢竟只是同學之間玩玩這個聊天室而已。
點擊去官網註冊Sunny-Ngrok
![在這裏插入圖片描述]()
註冊完後登錄後，點擊開通隧道。
![在這裏插入圖片描述]()
白嫖黨，選擇免費服務器。可能會有點卡，但是拿來使用聊天室夠了
![在這裏插入圖片描述]()
點擊確定後，按圖中說明填。
![在這裏插入圖片描述]()
查看隧道，下載該軟件，複製對應的TCP隧道ID
![在這裏插入圖片描述]()
下載好軟件後，點開目錄，啓動內網穿透
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
輸入隧道id，回車啓動即可
![在這裏插入圖片描述]()
接着，打開聊天室的服務器，記住剛剛填寫的本地的端口號，就是127.0.0.1:8888，這裏需要一致，我們填寫8888，啓動服務。
![在這裏插入圖片描述]()
在這個官網申請到的白嫖服務器的公網IP是64.69.43.237，端口號就是自己申請的，或者你可以查看運行的內網穿透窗口。
![在這裏插入圖片描述]()
接着，啓動客戶端，來測試一下是否成功連接上服務器。
![在這裏插入圖片描述]()
最後，連接成功，趕快把客戶端發給同學，大家一起來聊天室聊天吧，哈哈哈
![在這裏插入圖片描述]()
![在這裏插入圖片描述]()
最後
提供在線聊天室服務器端和用戶端生成的jar包和exe文件的集合壓縮包
