NameBinding annotations on resources are ignored in subresources ---------------------------------------------------------------- Key: WFLY-10319 URL: https://issues.jboss.org/browse/WFLY-10319 Project: WildFly Issue Type: Bug Components: REST Affects Versions: 12.0.0.Final Reporter: Javier Estevez Sanchez Assignee: Alessio Soldano Priority: Major The following JAX-RS resource exposes two resources via a GET operation: /demo and /demo/subresource. The first one via a sub-resource method, the latter via a sub-resource locator. Additionally, a response filter is binded to the JAX-RS resource class to modify the response. From the JAX-RS 2.0 spec, §6.5.2 Name Binding: {quote} Binding annotations that decorate resource classes apply to all resource methods defined in them. {quote} However, the binding annotation is not applying to the sub-resource locator method. This happens when the name binding annotation is on the resource class or on the sub-resource locator method. Annotating the sub-resource class or the method within works as expected, though. Below is the code needed to reproduce this issue: {code:java|title=The resource and subresource} @DemoNameBinding @Produces(MediaType.APPLICATION_JSON) @Path("/demo") public class DemoResource { @GET public String getDemoValue() { return "A value"; } @Path("/subresource") public DemoSubResource getSubResource() { return new DemoSubResource(); } public class DemoSubResource { @GET public String getDemoValue() { return "A value"; } } } {code} {code:java|title=The filter} @Provider @DemoNameBinding public class SomeFilter implements ContainerResponseFilter { @Override public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) { responseContext.setEntity("A filtered value"); } } {code} {code:java|title=The binding} @NameBinding @Target({ElementType.TYPE, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface DemoNameBinding { } {code}
