SpringSession集成redis实现session共享（No bean named 'springSessionRepositoryFilter' available）

分布式部署架构下传统的session共享有一定的局限性（你来到这儿想必已经受到了其带来的困扰），所以，springsession + redis（NSQL内存数据库）成了当下一个很好很时髦的选择

----Spring
Session provides an API and implementations for managing a user’s session information.

spring
session是一个独立于
spring、springMVC 的 HttpSession 管理工具包，在使用的过程中一定要注意！！！在web.xml配置springSessionRepositoryFilter过滤器的时候要指定redis和集成redis配置的配置文件位置，如下面配置代码，我只是将redis和集成redis的配置信息写在了springmvc的配置文件中，不要因为以前配置springmvc没有用到context-param指定springmvc配置文件的加载位置，就不用指定以下配置文件信息，会导致以下错误，让你抓狂：

不注意以上配置信息带来的抓狂错误信息：

spring session集成redis的配置：

1. web.xml

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>

classpath:spring/spring-mvc.xml

</param-value>

</context-param>

……

<filter>

<filter-name>springSessionRepositoryFilter</filter-name>

<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSessionRepositoryFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

2. spring-mvc.xml
