报错如题
配置如下
E:\EclipseWorkSpace\JavaEE\nutzbook\conf\shiro.ini
shiro.ini内容：

[main]

[urls]
/* = anon

web.xml:

<display-name>nutzbook</display-name>
	<listener>
		<listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class>
	</listener>
	<filter>
		<filter-name>ShiroFilter</filter-name>
		<filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>ShiroFilter</filter-name>
		<url-pattern>/*</url-pattern>
		<dispatcher>REQUEST</dispatcher>
		<dispatcher>FORWARD</dispatcher>
		<dispatcher>INCLUDE</dispatcher>
		<dispatcher>ERROR</dispatcher>
	</filter-mapping>

已至于所有filter之前，详细错误如下：

求解决方法
