Detailed error message:

Unable to load config Class.cn.itcast.shop.interceptor.PrivilegeInterceptor at interceptor

Probably due to a missing jar, which might is fine if you never plan to use the Privilegeinterceptor interceptor about Jars Package

(1) The error message shows a missing jar package, and the following are all the jar packs that are configured by the Structs2.3.2 version.

about Configuration

Registration information in Structs.xml:

<!--Configure Custom Interceptor-->
<interceptors>
        <interceptor name= "Privilegeinterceptor" class= Cn.itcast.shop.interceptor.PrivilegeInterceptor "/>
</interceptors>

<!--Configure the back-level category action- >
<action name= "admincategory_*" class= "admincategoryaction" method= "{1}" >
    <result name= " FindAll ">/admin/category/list.jsp</result>
  <!--reference Interceptor-->
    <interceptor-ref name=" Privilegeinterceptor "/>
    <interceptor-ref name= defaultstack"/>      
</action>   

The correct wording:

<!--in Spring Register Interceptor-->
<bean id= "Privilegeinterceptor" class= " Cn.itcast.shop.interceptor.PrivilegeInterceptor "scope=" prototype ">  
</bean>

<!--structs Configure custom interceptors-->
        <interceptors>
            <interceptor name= "Privilegeinterceptor" class= " Privilegeinterceptor "/>
        </interceptors>

Summary:

The lead jar package must be quoted. The implementation of the custom interceptor is not difficult to understand, we first wrote a Privilegeinterceptor class, and then because the SSH framework is used here, class creation is first given to spring management, So you can't register directly in Structs.xml, you should now register in spring.
Note that the IDs registered in spring correspond to the Name,class and name in structs and do not write the original path.
