內容管理項目小結 成功案例-公司官網，遊戲官網

1，架構

2，技術架構

3，應用的啓動過程

4，用戶的訪問過程（前端爲靜態的html頁面，這裏主要是後端）

5，高級的地方，經過泛型，抽象了整個的MVC訪問過程，對增刪改查只寫了一份代碼，每個新增的業務只需增長几個類，繼承複用泛型類便可。

6，tiles和基本展現控件包的使用

指定好定義tiles的配置文件,對象工廠，以及監聽器便可

7，小結

這是一個簡單卻經典的內容管理系統，在後臺管理數據，對數據進行增刪改查，數據管理好以後，使用freemarker生成靜態的html頁面，同時靜態資源分域，加快了站點的顯示速度；

後臺使用泛型和抽象類，大大的減小了重複代碼的數量，引入Guice容器，減小了對象的實例的互相依賴，同時使得程序的結構更加的清晰，hibernate簡化了持久層代碼的編寫，tiles和數據展現控件的使用使得後端的數據展現比較美觀，簡單卻使用的站點發布系統，經過這個項目，我熟悉了struts2,guice,hibernate，tiles技術，惟一一個以爲比較不妥的地方就是雖然大大的減小了重複代碼，可是新增模塊的話須要增長不少的類，若是能夠定義一個公共的動態定位的類來頂替這些大量的只是簡單繼承的類我以爲後端的代碼會更加整潔。
