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][Java_ _ Maven_IDEA_Maven_web]

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.

![70][]

一.创建一个Maven项目,将**Create from archetype(原型)勾选上**

![70 1][]

然后next

![70 2][]

然后next

![70 3][]

![70 4][]

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

![70 5][]

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

![70 6][]

3.编写配置文件

web.xml

      <context-param>

        <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
      </context-param>
