Spring MVC集成Spring Data Reids和Spring Session实现Session共享出现：No bean named 'springSessionRepositoryFilter' available

出现这个问题：No bean named 'springSessionRepositoryFilter' available的的原因：

1、Spring MVC加载了多个配置文件导致的，并不是版本问题。

2、如果使用org.springframework.web.context.ContextLoaderListener进行加载其它XML文件时，那么配置Redis和Session必须写在这些文件的其中一个上。

3、如果只是写在了org.springframework.web.servlet.DispatcherServlet时，没有其它的配置文件加载，那么Redis和Session都写在这个文件上。

4、org.springframework.web.filter.DelegatingFilterProxy必须写在第一位。

比如下面是我的配置文件：

<web-app id="WebApp_ID" version="3.0"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   </bean>

</beans>

可以看出两个配置文件都指定了annotation-config和component-scan。
