浅谈SpringMVC+Spring3+Hibernate4开发环境搭建

时间:2020-07-21 12:26     来源/作者:shan9liang

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
