shiro错误No SecurityManager accessible to the calling code

Shire在Web.xml中shiroFilter的Mapping配置错误

org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton. This is an invalid application configuration.

出错的原因在于没有配置shiroFilter,应该在web.xml加入代码：

shiroFilterorg.springframework.web.filter.DelegatingFilterProxyshiroFilter/*，这种精神使人能在旅行中和大自然更加接近，
