java - spring interceptor is never called -

i have following interceptor:

@component public class externallinkinterceptor extends handlerinterceptoradapter {      private static final logger logger = logger.getlogger(externallinkinterceptor.class);      @override     public boolean prehandle(httpservletrequest request, httpservletresponse response, object handler)             throws exception {         logger.info("prehandle ~ invoked"); } } 

it supposed intercept before request handle following controller method:

@controller @preauthorize("isauthenticated()") @requestmapping("/assay/process") public class variantprioritizationscontroller extends assaybasecontroller{      private static final logger logger = logger.getlogger(variantprioritizationscontroller.class); @requestmapping("/openanalyticalprojectforassay")     public modelandview openanalyticalprojectforassay(httpsession session,@requestparam(value = "analyticalprojid", required=true)string projectid) throws pandaapplicationexception{     //code       } } 

this interceptor declaration in spring-servlet.xml:

<mvc:interceptors>         <mvc:interceptor>             <mvc:mapping path="/assay/process/openanalyticalprojectforassay*"/>             <beans:bean class="com.syngenta.panda.web.mvc.interceptor.externallinkinterceptor"/>         </mvc:interceptor>     </mvc:interceptors> 

now interceptor never invoked , don't know why?! help

please try updating mvc:mapping path to:

<mvc:mapping path="/assay/process/**" />
