No bean named 'shiroFilter' is defined 这句话写的很清楚，就没有shiroFilter 就是没有权限框架拦截器的定义。

web.xml文件配置如下：

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

<!-- 修改 Servlet 版本-->
<!-- 配置 DispatcherServlet-->

<context-param>

<!-- 添加 Shiro 相关配置(应该去官网查询相应的配置信息) -->

<!-- The filter-name matches name of a 'shiroFilter' bean inside applicationContext.xml -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>

<!-- Make sure any request you want accessible to Shiro is filtered. /* catches all -->
<!-- requests. Usually this filter mapping is defined first (before all others) to -->
<!-- ensure that Shiro works in subsequent filters in the filter chain: -->
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

可以发现，问题出在shiroFilter没有被spring容器加载。。。
解决办法：

只需要在

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring/spring-service.xml,
classpath:spring/spring-dao.xml,
classpath:spring/spring-shiro.xml
</param-value>
</context-param>

添加：classpath:spring/spring-shiro.xml
