Spring rejecting bean name, no URL paths specified

I am trying to register an interceptor using a annotation-driven controller configuration. As far as I can tell, I've done everything correctly but when I try testing the interceptor nothing happens. After looking in the logs I found the following:

2010-04-04 20:06:18,231 DEBUG [main] support.AbstractAutowireCapableBeanFactory (AbstractAutowireCapableBeanFactory.java:452) - Finished creating instance of bean     'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0'
2010-04-04 20:06:18,515 DEBUG [main] handler.AbstractDetectingUrlHandlerMapping (AbstractDetectingUrlHandlerMapping.java:86) - Rejected bean name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0': no URL paths identified
2010-04-04 20:06:19,109 DEBUG [main] support.AbstractBeanFactory (AbstractBeanFactory.java:241) - Returning cached instance of singleton bean 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0'

Look at the second line of this log snippet. Is Spring rejecting the DefaultAnnotationHandlerMapping bean? And if so could this be the problem with my interceptor not working?

Here is my application context:

<?xml version="1.0" encoding="UTF-8"?>

<context:component-scan base-package="

<bean id="authorizedUserInterceptor" class="com.splash.web.handler.AuthorizedUserInterceptor"/>

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="interceptors">
        <list>
            <ref bean="authorizedUserInterceptor"/>
        </list>
    </property>
</bean>

Here is my interceptor:

package com.splash.web.handler;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

    public class AuthorizedUserInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request,
            HttpServletResponse response, Object handler) throws Exception {

        log.debug(">>> Operation intercepted...");        

        return true;
    }    
}

Does anyone see anything wrong with this? What does the error I mentioned above actually mean and could it have any bearing on the interceptor not being called? Thanks!

What you're seeing is a clash between <mvc:annotation-driven /> and the explicit bean definition of DefaultAnnotationHandlerMapping.

When you add <mvc:annotation-driven />, Spring declares its own DefaultAnnotationHandlerMapping, and because it appears before your own one, it gets priority. Your interceptor is registered with your DefaultAnnotationHandlerMapping, but that never actually get called.

Try removing <mvc:annotation-driven /> and trying again.

found from http://forum.springsource.org/showthread.php?t=81238. Use

<mvc:annotation-driven/>

followed by

<mvc:interceptors> <bean class="com.splash.web.handler.AuthorizedUserInterceptor"/></mvc:interceptors>
