在web.xml文件中增加以下代码,确保Web项目中需要权限管理的URL都可以被Shiro拦截过滤。
<!-- Shiro Filter --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>通常将这段代码中的filter-mapping放在所有filter-mapping之前,以达到shiro是第一个对web请求进行拦截过滤之目的。这里的fileter-name应该要和第二步中配置的 Java
bean的id一致。
在root-context.xml文件中配置Shiro

上述代码中已经对每个 java bean的用途做了详细的注释说明,这里仅对FilterChain过滤链的定义详细阐述一下:
完成这两步之后,我们可以Run一下程序,如果可以看到以下页面,就表明我们的配置文件没有错误,Shiro和 spring MVC的整合已经完成了。后继的步骤可以视为是对整合后的框进行的一个 测试 。

后台登录代码

登录成功后,会转至首页,并显示出当前用户名。
