前言
最近將Spring,Struts,Hiberbate基礎(chǔ)已經(jīng)學(xué)習(xí)完成。想自己把這三個(gè)框架集成一下，然后再寫(xiě)一個(gè)后臺(tái)管理網(wǎng)站練練手。Spring的作用是依賴(lài)注入，而Struts是顯示層的東西，這兩個(gè)框架集成后是什么樣子。一邊學(xué)習(xí)，一邊記錄。上車(chē)。
Spring集成所需jar包
首先，Spring集成Struts，那么applicationContext.xml和struts.xml,web.xml肯定是不能少的。前面兩個(gè)是Spring和Struts的配置文件，后面一個(gè)是整個(gè)web的全局配置文件。在每個(gè)配置文件中應(yīng)該怎么配置，怎么相互關(guān)聯(lián)呢。其實(shí)就是將Struts中指定的Action 類(lèi)為Spring注入的類(lèi)。
三大框架集成開(kāi)發(fā)并不難，難的地方在于各個(gè)包的依賴(lài)要搞清楚，版本之間的差異也是一點(diǎn)。下面列出Spring集成Struts所依賴(lài)的包:
依賴(lài)包
此處所有依賴(lài)為Struts2.0和Spring3.0。版本有點(diǎn)老，我用最新版的始終集成不正確。等搞好了再升級(jí)版本。
