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