Java框架基础教程 : 使用Maven搭建SSH项目(Idea)
本教程是在Idea中使用Maven搭建Struts2+Spring3+hibernate4的开发环境
做Java开发有一年多了,几个项目中使用最多的还是这套SSH框架,在这里记录一下
Maven的安装与配置以及创建一个web项目可以看下面这篇博文
Java框架基础教程 : Maven安装与配置以及在IDEA中使用Maven创建一个web项目
这里使用的是IDEA,虽然最早做Java开发时用的是Eclipse,也用了很久,但后来用了IDEA后,再用Eclipse总觉得很不方便.
一.创建一个Maven项目,将Create from archetype(原型)勾选上
然后next
然后next
接下来点击Finish,等待maven下载所需的依赖包,项目就已经搭建好了
二.配置SSH环境.
1.配置pom.xml (下载所需的Jar包)
更改pom.xml后,Maven会自动从中心仓库下载所需的Jar包,我用的是阿里的仓库.

2.更改项目结构 (增加所需的文件夹)
src/main/java:存放java源文件
src/main/resources:存放项目配置文件，如struts.xml,spring.xml,hibernate.cfg.xml等
3.编写配置文件
