    2 /src/main/webapp/WEB-INF/lib/中添加cglib-3.1.jar

    二、配置web.xml

    [html] view plain copy

    26.     </filter-mapping>  
    27.   
    28.     <!-- 添加Spring-Security过滤器 -->  
    29.     <filter>  
    30.         <filter-name>springSecurityFilterChain</filter-name>

    50.     </servlet-mapping>  
    51.   
    52. </web-app>  

    三、配置applicationContext-config.xml

    [html] view plain copy
     
     在CODE上查看代码片派生到我的代码片
    1. <?xml version="1.0" encoding="UTF-8"?>

    15.     <import resource="classpath*:config/spring/applicationContext-resources.xml" />  
    16.   
    17. </beans>  

    四、配置applicationContext-resource.xml

    五、配置configuration.xml
