### 1、构建maven结构（略） ###

[http://blog.csdn.net/bestcxx/article/details/54589039][http_blog.csdn.net_bestcxx_article_details_54589039]

本篇配置文件没有分离：[Spring Web Flow 简单实现-自定义配置文件位置][Spring Web Flow _-]

### 2、Spring Web Flow Maven依赖 ###

<dependency>
    		    <groupId>org.springframework.webflow</groupId>
    		    <artifactId>spring-webflow</artifactId>
    		    <version>2.4.5.RELEASE</version>
    		</dependency>

### ３、pom.xml 全部内容 ###
