Java – Jersey 2.2: containerresponsefilter and containerrequestfilter will never be executed

After the getting started guide on the Jersey website:

I executed the following build commands:

$mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-grizzly2 \
-DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
-DgroupId=com.example -DartifactId=simple-service -Dpackage=com.example \
-DarchetypeVersion=2.2

Then I follow the tutorial

https://jersey.java.net/documentation/latest/filters-and-interceptors.html#d0e6783

To add a custom containerresponsefilter:

@NameBinding
@Retention(RetentionPolicy.RUNTIME)
static @interface CORSBinding {}

@Provider
@Priority(Priorities.HEADER_DECORATOR)
@CORSBinding
static class CrossDomainFilter implements ContainerResponseFilter {
    @Override
    public void filter(ContainerRequestContext creq,ContainerResponseContext cres) {
        Logger.getLogger("com.example").log( Level.INFO,"before: {0}",cres.getHeaders());
        cres.getHeaders().add("Access-Control-Allow-Origin","*");
        cres.getHeaders().add("Access-Control-Allow-Headers","origin,content-type,accept,authorization");
        cres.getHeaders().add("Access-Control-Allow-Credentials","true");
        cres.getHeaders().add("Access-Control-Allow-Methods","GET,POST,PUT,DELETE,OPTIONS,HEAD");
        cres.getHeaders().add("Access-Control-Max-Age","1209600");
        Logger.getLogger("com.example").log( Level.INFO,"after: {0}",cres.getHeaders());
    }
}

@Provider
static class MyResponseFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext,ContainerResponseContext responseContext) throws IOException {
        System.out.println("MyResponseFilter.postFilter() enter");
        responseContext.setEntity(
                responseContext.getEntity() + ":" + getClass().getSimpleName(),null,MediaType.TEXT_PLAIN_TYPE);
        System.out.println("MyResponseFilter.postFilter() exit");
    }
}

...
@GET
@Produces(MediaType.TEXT_PLAIN)
@CORSBinding
public String helloWorld() {
    return "hello world";
}

I tried to register this filter with named binding and dynamic binding, and it didn't work

To facilitate reproduction, I also tried an example of official resources:

https://github.com/jersey/jersey/tree/2.2/examples/exception-mapping

The same problem: custom filters will not be executed

Is this a grizzly bear problem?

Solution

It turns out that you have to register custom classes manually – for example:

rc.register(com.dummy.mypackage.CORSResponseFilter.class);

Complete example:

/**
 * Main class.
 *
 */
public class Main {
    // Base URI the Grizzly HTTP server will listen on
    public static final String BASE_URI = "http://192.168.1.34:8080/myapp/";

    /**
     * Starts Grizzly HTTP server exposing JAX-RS resources defined in this application.
     * @return Grizzly HTTP server.
     */
    public static HttpServer startServer() {
        // create a resource config that scans for JAX-RS resources and in com.example package
        final ResourceConfig rc = new ResourceConfig().packages("com.dummy.mypackage");

        //NEW: register custom ResponseFilter
        rc.register(com.dummy.mypackage.CORSResponseFilter.class);

        // Register Jackson JSON
        rc.packages("org.glassfish.jersey.examples.jackson").register(JacksonFeature.class);

        // create and start a new instance of grizzly http server
        // exposing the Jersey application at BASE_URI
        return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI),rc);
    }
    ...
}
