求解：<mvc:interceptors>标签问题

Question

今天想写拦截器，但是出现问题。一直报org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.handler.MappedInterceptor#1': Cannot create inner bean 'interceptor.PermissionInterceptor#0' of type [interceptor.PermissionInterceptor] while setting constructor argument; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [interceptor.PermissionInterce ptor] for bean with name 'interceptor.PermissionInterceptor#0' defined in file [D:\Documents\eclipseProjects\SIMS\target\SIMS-0.0.1-SNAPSHOT\WEB-INF\classes\spring-web.xml]; nested exception is java.lang.ClassNotFoundException: interceptor.PermissionInterceptor
配置文件中写的是我自己想写的拦截器类PermissionInterceptor就不行，换成springwebjar包下的interceptor类就可以启动不报错，请问这是什么原因？怎么样才能用我自己写的interceptor。(注:同事说jdk换成1.8就好了，我的jdk是1.6,1.6也支持interceptor哇，求大神给讲讲)

Answer 1

你自己的写的拦截器 需要继承一个拦截器的类
