How do I configure Glassfish 5 to use Moxy as the default Provider?

问题

I’m migrating our web application from Glassfish 3 to Glassfish 5, and during the migration I ran across this error for a request.

It appears Glassfish 5 is using JSON-B serialization. Glassfish 5 ignores JAXB @XmlJavaTypeAdapter annotation?

In the past we used moxy and jaxb for json binding, and as a result I’ve been trying to register Moxy as the default provider in Glassfish 5. I’ve followed the instructions here with no luck.

https://howtodoinjava.com/jersey/jax-rs-jersey-moxy-json-example/

I also read the Glassfish 5 documentation, but did not find any similar examples for registering a default provider. If someone could shed some light on what I’m doing wrong in the configuration that would be greatly appreciated. I’ve provided samples of my configuration below.

How do I configure Glassfish 5 to use Moxy as the default Provider?

Notes:

When I start glassfish, I've debugged the JsonServicesContextResolver.java class and verified the constructor and getContext method are hit during initialization.
I've tried removing the GridApplication.java class and removing its references in the web.xml, thinking the jersey.config.server.provider.packages may already register any providers in those packages. I still had the same errors.

JsonServicesContextResolver.java

package com.lnka.eng.grid.jersey;

import org.eclipse.persistence.jaxb.JAXBContextProperties;
import org.glassfish.jersey.moxy.json.MoxyJsonConfig;

import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

@Provider
public class JsonServicesContextResolver
    implements ContextResolver<MoxyJsonConfig>
{
  private MoxyJsonConfig config;

  public JsonServicesContextResolver()
  {
    config = new MoxyJsonConfig()
        .setNamespaceSeparator(':')
        .setAttributePrefix("")
        .setValueWrapper("value")
        .property(JAXBContextProperties.JSON_WRAPPER_AS_ARRAY_NAME, true)
        .setFormattedOutput(true)
        .setIncludeRoot(true)
        .setMarshalEmptyCollections(true);
  }

  @Override
  public MoxyJsonConfig getContext(Class<?> objectType)
  {
    return config;
  }
}

ProgramsController.java

package com.lnka.eng.view.controller;

@Path("/mgmt/programs/")
@Stateless
@Transactional(Transactional.TxType.NOT_SUPPORTED)
public class ProgramsController extends Controller
{
 @GET
  @Path("/list/")
  @Produces(MediaType.APPLICATION_JSON)
  public Response getProgramsList()
  {
    List<Program> programs = getPrograms();

    return Response.ok(programs).build();    
  }
}

GridApplication.java

package com.lnka.eng.grid.jersey;

import com.lnka.eng.view.controller.ProgramsController;

import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;

public class GridApplication extends Application
{
  //Add Service APIs
  @Override
  public Set<Class<?>> getClasses()
  {
    Set<Class<?>> resources = new HashSet<Class<?>>();

    //register REST modules
    resources.add(ProgramsController.class);

    //Manually adding MOXyJSONFeature
    resources.add(org.glassfish.jersey.moxy.json.MoxyJsonFeature.class);

    //Configure Moxy behavior
    resources.add(JsonServicesContextResolver.class);

    return resources;
  }
}

web.xml

I've removed some of the config in this file that I thought irrelevant (security, ejb config, etc)

回答1:

The issue was we needed to update the web.xml to include the MoxyConfig in the session-config scope. I was also missing some configuration for one of our listeners, but the relevant code is below.

The following was placed inside each of the <servlet>...</servlet> tags.

<init-param>
      <param-name>jersey.config.server.jsonFeature</param-name>
      <param-value>MoxyJsonFeature</param-value>
</init-param>
