早期的項(xiàng)目比較簡(jiǎn)單，多是用JSP 、Servlet + JDBC 直接搞定，后來(lái)使用 Struts1(Struts2)+Spring+Hibernate, 嚴(yán)格按照分層概念驅(qū)動(dòng)項(xiàng)目開(kāi)發(fā)，這次又使用 Spring MVC取代Struts來(lái)進(jìn)行開(kāi)發(fā)。
MVC已經(jīng)是現(xiàn)代Web開(kāi)發(fā)中的一個(gè)很重要的部分，下面介紹一下SpringMVC+Spring3+Hibernate4的開(kāi)發(fā)環(huán)境搭建
先大致看一下項(xiàng)目結(jié)構(gòu)：
具體的代碼不再演示，主要是走了一個(gè)很平常的路線，mvc-servcie-dao-hibernate的結(jié)構(gòu)，源碼可以下載，主要看一下配置文件。解釋見(jiàn)注釋
