exception - Handling error 500 by Interceptor in Spring MVC -

i have created interceptor class , have overridden aftercompletion method. when ever system throws error ( 500, 404 ), system breaks , not reach aftercompletion method of interceptor. there way request can reach aftercompletion method exception occured.

interceptor class

public class classname extends handlerinterceptoradapter {   @override public void aftercompletion(httpservletrequest request,httpservletresponse response, object handler, exception ex) throws exception {     if (ex != null) {         //do somthing here     } } 

}

interceptor declaration

   <mvc:interceptors>         <bean class="x.y.z.classname" />     </mvc:interceptors>  

can guide me 1 this.

i using swf + mvc , realized different ways of registering interceptors ,

<bean class="org.springframework.webflow.mvc.servlet.flowhandlermapping">     <property name="flowregistry" ref="datacollectorflowregistry" />     <property name="interceptors">         <list>             <ref bean="localechangeinterceptor"/>         </list>     </property> </bean> 

this works me.
