JPA CDI JAXB - Setter被忽略了

我的JAX-RS资源成功从db获取JPA / JAXB实体和JPA / JAXB实体列表。

一个实体充当父实体。实体列表是父实体中的字段。我无法将父实体列表设置为返回的实体列表。父实体在JAXB父实体中返回，但这不会影响该情况。

以下是代码：

@Inject
InventoryService inventoryService;
@Inject
HcUser user;
@Inject
InventoryResponse inventoryResponse;

@GET
@Produces(MediaType.APPLICATION_JSON)
public InventoryResponse getInventory(@Context HttpServletRequest request, 
                                      @HeaderParam(IDENTITY_URL) String identityURL, 
                                      @HeaderParam(ACCESS_TOKEN) String accessToken) {

    String username = (String) request.getAttribute("username");
    user = inventoryService.getUserById(username);
    user.setHcCounts(inventoryService.getCountsForUserId(username));
    inventoryResponse.setUser(user);

    return inventoryResponse;
}

返回的JSON仅返回用户对象。我尝试手动实例化用户对象并将其设置为getUserById方法的返回值，然后使用返回的列表调用setHcCounts。但是，设置器仍然被忽略。

我做错了什么？

我正在使用WAS v8.0.0.8。堆栈是：

JAX-RS - Apache Wink v1.1.1（由WAS 8提供）

OpenJPA - Apache v2.1.2-SNAPSHOT（由WAS 8提供）

JAXB - MOXy v2.7

CDI - Apache OpenWebBeans 1.0（由WAS 8提供）

EJB - Apache OpenEJB（由WAS 8提供）

更新1 这是InventoryResponse课程的要求，但我不认为这是必要的。在检查用户对象时，在inventoryResonse.setUser(user)之前的行上，在调试期间，hcCounts为空。

@Named
@RequestScoped
@XmlRootElement
public class InventoryResponse implements Serializable {

    private static final long serialVersionUID = 1L;

    @Inject
    private HcUser user;

    private List<HcLocation> locations;

    public HcUser getUser() {
        return user;
    }

    public void setUser(HcUser user) {
        this.user = user;
    }

    public List<HcLocation> getLocations() {
        return locations;
    }

    public void setLocations(List<HcLocation> locations) {
        this.locations = locations;
    }
}

更新2 根据要求，HcUser：

更新4 我找到了一个解决方法...... 

public InventoryResponse getInventory(@Context HttpServletRequest request, @HeaderParam(IDENTITY_URL) String identityURL, @HeaderParam(ACCESS_TOKEN) String accessToken) {
    String username = (String) request.getAttribute("username");
    user = inventoryService.getUserById(username);
    List<HcCount> counts = inventoryService.getCountsForUserId(username);
    HcUser newUser = new HcUser();
    newUser.setHcCounts(counts);
    inventoryResponse.setUser(newUser);

    return inventoryResponse;
}
