错误代码情况：

严重: Exception starting filter shiroFilter

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：

    
    
    
     
        contextConfigLocation  
   		classpath:spring/spring-web.xml  
     
    
    
        org.springframework.web.context.ContextLoaderListener
    
    
    
        springMVC
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            
                classpath:spring/spring-web.xml
            
        
        1
        true
    

    
        springMVC
        /
    

    
        initServlet
        com.liwei.shiro.web.InitServlet
        1
    


    
        contextConfigLocation
        
            classpath:spring/spring-service.xml,
            classpath:spring/spring-dao.xml,
            
        
    




    

    
    
        shiroFilter
        org.springframework.web.filter.DelegatingFilterProxy
        
            targetFilterLifecycle
            true
        
    

    
    
    
    
        shiroFilter
        /*
    

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

    
        contextConfigLocation
        
            classpath:spring/spring-service.xml,
            classpath:spring/spring-dao.xml,
            classpath:spring/spring-shiro.xml
        
    

添加： classpath:spring/spring-shiro.xml
