未为子资源调用 JAX-RS DynamicFilter

根据文档，应该可以使用DynamicFeature https://docs.oracle.com/javaee/7/api/javax/ws/rs/container/DynamicFeature.html对于资源和子资源。作为效果，我希望每当调用子资源端点时都会注册和调用过滤器 - 即GET /some/sub/x。但是以下对我不起作用（也不适合其他类似的方法）：

• 注解

  @NameBinding
  @Target({METHOD, TYPE})
  @Retention(RetentionPolicy.RUNTIME)
  public @interface SomeFilterAnn {}
  

• resource

  @SomeFilterAnn
  @Path("/some")
  public class SomeResource {
    @GET
    public String getSome() {
      return "some";
    }
  
    @Path("/sub")
    public SubResource getSub() {
      return new SubResource();
    }
  
    @SomeFilterAnn
    @Path("/x")
    public static class SubResource {
      @GET
      public String getSome() {
        return "sub";
      }
    }
  }
  

• 过滤器（它实际上更复杂并且配置为DynamicFilter)

  @SomeFilterAnn
  public class SomeFilter implements ContainerRequestFilter {
    private static final Logger LOG = LoggerFactory.getLogger(SomeFilter.class);
  
    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {
      LOG.info("filter called");
    }
  }
  

• here is DynamicFeature我想注册资源和子资源的过滤器。其实我希望configure()也会被要求SubResource so resourceInfo.getResourceClass() == SubResource.class但无法实现这一点。

  @Provider
  public class SomeDynamicFeature implements DynamicFeature {
    private static final Logger LOG = LoggerFactory.getLogger(SomeDynamicFeature.class);
  
    @Override
    public void configure(ResourceInfo resourceInfo, FeatureContext context) {
      Class<?> resourceClass = resourceInfo.getResourceClass();
  
      // this works
      if (resourceClass == SomeResource.class) {
        LOG.info("register resource filter");
        context.register(new SomeFilter(/*some config*/));
      }
  
      // this does not work (not called for Subresource)
      if (resourceClass == SomeResource.SubResource.class) {
        LOG.info("register resource filter");
        context.register(new SomeFilter(/*some config*/));
      }
  
      // this also does not work (filter not called for Subresource)
      if (resourceInfo.getResourceMethod().getReturnType() == SomeResource.SubResource.class) {
        LOG.info("register subresource filter");
        context.register(new SomeFilter(/*some config*/));
      }
    }
  }
  

我在 WildFly 8.2 上使用 CXF 运行此程序，但没有 Jersey 或 RESTEasy

EDIT

我发现注释SomeFilter with @Provider允许过滤器工作而无需DynamicFeature但是我不知道如何配置我的过滤器 - 这是单独的问题 https://stackoverflow.com/questions/33329853/how-can-i-provide-configuration-to-jax-rs-provider-annotated-containerrequestfi关于它。
