SpringMVC+Spring3+Hibernate4开发环境搭建

早期的项目比较简单，多是用JSP 、Servlet + JDBC 直接搞定，后来使用 Struts1(Struts2)+Spring+Hibernate, 严格按照分层概念驱动项目开发，这次又使用 Spring MVC取代Struts来进行开发。

MVC已经是现代Web开发中的一个很重要的部分，下面介绍一下SpringMVC+Spring3+Hibernate4的开发环境搭建

先大致看一下项目结构：

 

具体的代码不再演示，主要是走了一个很平常的路线，mvc-servcie-dao-hibernate的结构，源码可以下载，主要看一下配置文件。解释见注释

下面再来看看Controller
