import javax.servlet.http.HttpServletRequest;

if (args[i] instanceof ActionMapping) mapping = (ActionMapping)args[i];
}
if ( request.getSession().getAttribute("adminname") != null)

return invocation.proceed();
}
else

Java代码

class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
"beanNames">
/vaiiduser
/admin
/phone
"interceptorNames">
