Eclipse JAXRS POST Request payload not converted into request model object

I have a JSON payload sent as part of POST request body like:

{
    "id": "xyz3",
    "model": "Camry",
    "year": 2010
}

And I would expect this payload to be converted to the instance of my java class CarRequest defined like:

import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import org.apache.commons.lang3.builder.ToStringBuilder;
import org.apache.commons.lang3.builder.ToStringStyle;
...

@XmlRootElement(name = "carRequest")
@XmlAccessorType(XmlAccessType.FIELD)
public class CarRequest {

	private String id;
	private String model;
	private int year;

	public CarRequest() {
	}

	public String getId() {
		return id;
	}
	
	public String getModel() {
		return model;
	}
	
	public int getYear() {
		return year;
	}

	@Override
	public String toString() {
		return ToStringBuilder.reflectionToString(this, ToStringStyle.JSON_STYLE);
	}
}

However, in my POST endpoint resource method I dont see this happening. My resource is defined as:

@POST
@Path("cars")
@Produces({ "application/json", "application/xml" })
public Response carsInfos(@Valid CarRequest carRequest) {
	
	System.out.println(carRequest);   //prints { "id": "null", "model": "null", "year": 0 }
	
	return Response.ok().build();
}

Above, the line that prints carRequest prints it like

{ "id": "null", "model": "null", "year": 0 }

, instead of like

{ "id": "xyz3", "model": "Camry", "year": 2010 }

I've only ever used the Jackson annotations for specifying mappings, but I think the real problem here may be the lack of a "@Consumes" annotation. Because of that, I believe it doesn't know how to parse your request body.

I have tried @Consumes annotation (thanks @David M. Karr) but that did not solve anything. It turns out that my server was using JavaEE 8 with JAXRS 2.1 features.
After adding features for JavaEE7 and JAXRS 2.0, the request model started getting populated with the values.
