shiro+redis+springMvc整合配置及说明

技巧背景：shiro安全框架，redis作缓存，再整合spring。

1、配置web.xml

    <filter>
        <filter-name>ShiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>ShiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
