I read a lot about how to replace jackson for moxy on payara 5 but never achieve a good solution, so I create a small project and hope that someone can help me.

pom.xml

<dependencies>

    <dependency>

        <groupId>javax</groupId>

        <artifactId>javaee-web-api</artifactId>

        <version>${version.javaee}</version>

        <scope>provided</scope>

    </dependency>



    <!-- https://mvnrepository.com/artifact/org.glassfish.jersey.media/jersey-media-json-jackson -->

    <dependency>

        <artifactId>jersey-media-json-jackson</artifactId>

        <version>2.27</version>

    </dependency>



    <dependency>

        <groupId>org.eclipse.microprofile</groupId>

        <artifactId>microprofile</artifactId>

        <type>pom</type>

        <version>1.4</version>

    </dependency>

<dependencies>

App.java

import javax.ws.rs.ApplicationPath;

import javax.ws.rs.core.Application;



import org.glassfish.jersey.jackson.JacksonFeature;



@ApplicationPath("/api")

public class App extends Application {



@Override

public Set<Class<?>> getClasses() {

    Set<Class<?>> resources = new java.util.HashSet<>();

    resources.add(JacksonFeature.class);



    resources.add(SimpleService.class);

    return resources;

}



}

SimpleService.java

@Path("sample")

public class SimpleService {



@Path("greet2")

@GET

@Produces(MediaType.APPLICATION_JSON)

public PojoEntity doGreet2() {

    PojoEntity pojoEntity = new PojoEntity();

    pojoEntity.setTeste1("TesteValue1");

    pojoEntity.setTeste2("TesteValue2");

    return pojoEntity;

}

}

PojoEntity.java

public class PojoEntity {





private String teste1;



@JsonProperty("differentName")

private String teste2;



//getters and setters

}

After deploy this micro application into payara 5 and request the endpoint http://localhost:8080/micro-sample/api/sample/greet2 the result is (as expected):

{"teste1":"TesteValue1","differentName":"TesteValue2"}

Payara is using Jackson instead of moxy. :) Nice!!!

==============================================

My problem is when I use microprofile to reach my own endpoint:

SimpleServiceMicroprofileApi.java

import javax.enterprise.context.Dependent;

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.Produces;

import javax.ws.rs.core.MediaType;



import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;



@Dependent

@RegisterRestClient

@Produces(MediaType.APPLICATION_JSON)

public interface SimpleServiceMicroprofileApi {



    @Path("api/sample/greet2")

    @GET

    @Produces(MediaType.APPLICATION_JSON)

    public PojoEntity recallGreet2();

}

MicroService.java

    package fish.payara.micro.sample;



import java.net.MalformedURLException;

import java.net.URL;



import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.Produces;

import javax.ws.rs.core.MediaType;



import org.eclipse.microprofile.rest.client.RestClientBuilder;



@Path("micro")

public class MicroService {



    @Path("recallGreet2")

    @GET

    @Produces(MediaType.APPLICATION_JSON)

    public PojoEntity recallGreet2() throws MalformedURLException {

        PojoEntity pojoEntity = new PojoEntity();

        pojoEntity.setTeste1("LOL");

        pojoEntity.setTeste2("LOL2");



        URL apiUrl = new URL("http://localhost:8080/micro-sample");

        SimpleServiceMicroprofileApi playlistSvc = RestClientBuilder.newBuilder().baseUrl(apiUrl)

                .build(SimpleServiceMicroprofileApi.class);



        return playlistSvc.recallGreet2();

    }

}

And add this line on App.java on getClasses method:

resources.add(MicroService.class);

After the redeploy with this modifications we can access http://localhost:8080/micro-sample/api/micro/recallGreet2 and the result is:

{"teste1":"LOL","differentName":null}

Apparently microprofile keeps using moxy and ignore PojoEntity property "differentName".

Anyone know a way to completely replace moxy for jackson in this example?

This project is available here to make it possible to test this situation. :)

Payara version: 5.183

Thanks in advance.

You just need to register JacksonFeature on your SimpleServiceMicroprofileApi:

@RegisterProvider(JacksonFeature.class)

That should make it work;)
