Activate JaxbAnnotationModule on Wildfly

问题:

I am trying to setup a REST service on Wildfly 8 that returns JSON with customized enum Values. I know that Wildfy uses Jackson 2.3 for the serialisation. I also know that when registering the JaxbAnnotationModule with the Jackson ObjectMapper the serializer produces the correct result. The question is, how do i configure my Wildfly Instance or my web-project to use this module.

OK, to make this more clear, a simple example.

First, this works properly and generates the result I need.

@XmlEnum
public enum TestEnum
    @XmlEnumValue("2")
    TWO; 
}

public class Test {
    public static void main(String[] args) {

    ObjectMapper mapper = new ObjectMapper();
    JaxbAnnotationModule jaxbModule = new JaxbAnnotationModule();
    mapper.registerModule(jaxbModule);
    try {
        mapper.writeValue(System.out, TestEnum.TWO);
    } catch (Exception e) {
    }
}

This Produces the correct output: "2"

Now, to my problem service

@Path("test")
@RequestScoped
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public class TestRestService {

    @GET
    @Path("/json")
    @Produces({MediaType.APPLICATION_JSON})
    public TestEnum testJson() {
        return TestEnum.TWO;
    }
}

This returns "TWO" which is not what i intended.

I did not configure anything within the "jboss-deployment-structure.xml" nor the "web.xml".

I am not using maven so any pom.xml solutions won't work for me besides pointing me in the direction.

I read the documentation here but could not find the option to enable the JaxbAnnotationModule.

Any possibility to customize the enum value that works for JSON and XML would be apreciated.

----- UPDATE -----

In theory, the solution was already posted here

If I use that solution try to use the Jackson Mapper with the JaxbAnnotationModule it should create the correct output. 

@Provider
@Produces(MediaType.APPLICATION_JSON)
public class JacksonMapper implements MessageBodyWriter<Object> {

  ObjectMapper mapper;

  @PostConstruct
     void init() {
    mapper = new ObjectMapper();
    JaxbAnnotationModule jaxbModule = new JaxbAnnotationModule();
    // this is what is causing the current problem
    mapper.registerModule(jaxbModule);
  }

  @Override
  public boolean isWriteable(Class<?> aClass, Type type,
      Annotation[] annotations, MediaType mediaType) {
    return true;
  }

  @Override
  public long getSize(Object object, Class<?> aClass, Type type,
      Annotation[] annotations, MediaType mediaType) {
    return 0;
  }

  @Override
  public void writeTo(Object object, Class<?> aClass, Type type,
      Annotation[] annotations, MediaType mediaType,
      MultivaluedMap<String, Object> stringObjectMultivaluedMap,
      OutputStream outputStream) throws IOException,
      WebApplicationException {
    mapper.writeValue(outputStream, object);
  }

}

In my jboss-deployment-structure.xml i activate the necessary modules (or so i would think)

<dependencies>
  <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import" />
  <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
</dependencies>

when calling my test method i get a ClassNotFound exception on javax.xml.bind.annotation.XmlElement which should have been included by including "com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" since this is depending on "javax.ws.rs.api" which is then including "javax.xml.bind.api" which contains the missing class.

If i do not register the created jaxbModule to the mapper, all works fine except that the annotation @XmlEnumValue is ignored. I get the same output as without the changes.

Any Suggestions?

OP posted his solution:

It turns out that the the module description hast to be updated manually as described here even though the class should have been referenced.

SOLUTION: Update the file: wildfly-8.0.0.CR1\modules\system\layers\base\com\fasterxml\jackson\jaxrs\jackson-jaxrs-json-provider\main\module.xml 

<module xmlns="urn:jboss:module:1.1" name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider">
     <resources>
        <resource-root path="jackson-jaxrs-json-provider-2.2.3.jar"/>
        <resource-root path="jackson-jaxrs-base-2.2.3.jar"/>
        <resource-root path="jackson-module-jaxb-annotations-2.2.3.jar"/>
    </resources>

    <dependencies>
        <module name="javax.api"/>
        <module name="javax.ws.rs.api"/>
        <!-- Add this line -->
        <module name="javax.xml.bind.api" />

        <module name="com.fasterxml.jackson.core.jackson-annotations"/>
        <module name="com.fasterxml.jackson.core.jackson-core"/>
        <module name="com.fasterxml.jackson.core.jackson-databind"/>
    </dependencies>
</module>
