    Apply Filter or Interceptor on specific method using NameBinding

    andrea formica Newbie

      I tried to create filters and interceptors that would apply only to a specific method using an annotation derived from NameBinding.

       

      I'm using JBoss 7.1.1.Final, where I did upgrade the modules by unzipping resteasy-jaxrs-3.0-beta-1 zip .

       

      I have a couple of classes which define restful services, and I created (following examples as in http://docs.jboss.org/resteasy/docs/3.0-beta-1/javadocs/javax/ws/rs/NameBinding.html)

       

      1) an annotation

      @NameBinding

      @Target({ ElementType.TYPE, ElementType.METHOD })

      @Retention(value = RetentionPolicy.RUNTIME)

      public @interface FrontierResponse {

                String value() default "";

      }

       

       

      2)

           a Filter class , like

          

      @FrontierResponse

      public class FrontierResponseFilter implements ContainerResponseFilter {

       

        @Inject

                private Logger log;

       

        /* (non-Javadoc)

                 * @see javax.ws.rs.container.ContainerResponseFilter#filter(javax.ws.rs.container.ContainerRequestContext, javax.ws.rs.container.ContainerResponseContext)

                 */

        @Override

                public void filter(ContainerRequestContext ctx,

                                    ContainerResponseContext respctx) throws IOException {

        log.info("Frontier response filter :"+ctx.getMethod());

        .....

       

      3)

           a restful service class, with a method annotated with the previous annotation

       

        @FrontierResponse

        @GET

        @Produces("text/xml")

        @Path("/{schema}/{db}/nodes")

                public List<NodeType> listNodesInSchema(@PathParam("schema") String schema,

                                    @PathParam("db") String db) {

       

        log.info("Calling listNodesInSchema..."+schema+" "+db);

       

      I noticed that :

      1) if the filter class does not contain the @Provider annotation, then the filter is not applied at all...

      BUT

      2) if the filter class is annotated with @Provider...then ALL restful method do get filtered !

       

      I do not know where I can have done something wrong, I suspect a bad installation, bad if somebody could enlight me I would

      be grateful ;-)
