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:

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

<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!
