# 前言 #

本博文主要讲解**Spring怎么与Struts2框架整合**…

**Struts2和Spring的整合关键点**：

*  **action对象交给Spring来创建**

# 搭建环境 #

## 进入jar包 ##

引入jar文件:

*  **1）引入struts .jar相关文件**
 *  **2）spring-core 相关jar文件**
 *  **3）spring-web 支持jar包**  
    
    
     *  **spring-web-3.2.5.RELEASE.jar 【Spring源码】**
     *  **struts2-spring-plugin-2.3.4.1.jar 【Struts源码】**

## 写配置文件 ##

*  **struts.xml 【struts路径与action映射配置】**
 *  **bean.xml 【spring ioc容器配置】**
 *  **web.xml**  
    
    
     *  **【核心过滤器： 引入struts功能】**
     *  **【初始化spring的ioc容器】查看Spring的API**

--------------------

# web.xml文件 #

**web.xml文件**

**除了要配置Struts2的分配器，还要加载Spring的配置文件**
