內(nèi)容管理項(xiàng)目小結(jié) 成功案例-公司官網(wǎng)，游戲官網(wǎng)
1，架構(gòu)
2，技術(shù)架構(gòu)
3，應(yīng)用的啟動(dòng)過程
4，用戶的訪問過程（前端為靜態(tài)的html頁(yè)面，這里主要是后端）
5，高級(jí)的地方，通過泛型，抽象了整個(gè)的MVC訪問過程，對(duì)增刪改查只寫了一份代碼，每一個(gè)新增的業(yè)務(wù)只需增加幾個(gè)類，繼承復(fù)用泛型類即可。

6，tiles和基本展示控件包的使用
指定好定義tiles的配置文件,對(duì)象工廠，以及監(jiān)聽器即可

7，小結(jié)
這是一個(gè)簡(jiǎn)單卻經(jīng)典的內(nèi)容管理系統(tǒng)，在后臺(tái)管理數(shù)據(jù)，對(duì)數(shù)據(jù)進(jìn)行增刪改查，數(shù)據(jù)管理好之后，使用freemarker生成靜態(tài)的html頁(yè)面，同時(shí)靜態(tài)資源分域，加快了站點(diǎn)的顯示速度；
后臺(tái)使用泛型和抽象類，大大的減少了重復(fù)代碼的數(shù)量，引入Guice容器，減少了對(duì)象的實(shí)例的互相依賴，同時(shí)使得程序的結(jié)構(gòu)更加的清晰，hibernate簡(jiǎn)化了持久層代碼的編寫，tiles和數(shù)據(jù)展示控件的使用使得后端的數(shù)據(jù)展示比較美觀，簡(jiǎn)單卻使用的站點(diǎn)發(fā)布系統(tǒng)，通過這個(gè)項(xiàng)目，我熟悉了struts2,guice,hibernate，tiles技術(shù)，唯一一個(gè)覺得比較不妥的地方就是雖然大大的減少了重復(fù)代碼，但是新增模塊的話需要增加很多的類，如果可以定義一個(gè)公共的動(dòng)態(tài)定位的類來頂替這些大量的只是簡(jiǎn)單繼承的類我覺得后端的代碼會(huì)更加整潔。
