1，在web.xml中配置fiter，如下所示

         
         
             
      
       shiroFilter
              
      
       org.springframework.web.filter.DelegatingFilterProxy
              
              
                  
       
        targetFilterLifecycle
                   
       
        true
               
              
              
                  
       
        targetBeanName
                   
       
        shiroFilter
               
          
         
             
      
       shiroFilter
              
      
       /*
          
     

2，上面配置了shiroFilter，那么在spring-shiro.xml中要配置shirofilter bean

         
         
             
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
                  
                       
                        /styles/easyui/** = anon                /scripts/easyui/** = anon                /styles/** = anon                /images/** = anon                
                        /logout = logout                
                        
                        
                        
                        
                        
                        /login = anon                /** = authc            
               
          
     

3，在spring-shiro.xml中添加securityManager和自定义realm，ecacheManager的相关配置

3，在spring-shiro.xml中，开启shiro的注解支持

4，在spring-shiro.xml中配置shiro认证异常的页面

             
                  
                       
        
         /errorpage/refuse
