No bean named 'shiroFilter' is defined 這句話寫的很清楚，就沒有shiroFilter 就是沒有許可權框架攔截器的定義。

web.xml檔案配置如下：

<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

         version="3.0">

    <!-- 修改 Servlet 版本-->

    <!-- 新增 Shiro 相關配置(應該去官網查詢相應的配置資訊) -->

    <!-- Make sure any request you want accessible to Shiro is filtered. /* catches all -->

可以發現，問題出在shiroFilter沒有被spring容器載入。。。

解決辦法：

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>

新增：classpath:spring/spring-shiro.xml
