带有POJO到JSON列表的POJO显示大小和索引

Question

所以我有2个Pojos：

public class RequestDisplayInfo {
    private int nombrePersonne;
    private String courrielOrganisateur;
    private RequestStatus statutDemande;
    private String salleAssigne;

    getters/setters.....

和

public class RequestsDisplayInfo {
    private List<RequestDisplayInfo> acceptees = new ArrayList<RequestDisplayInfo>();
    private List<RequestDisplayInfo> autres = new ArrayList<RequestDisplayInfo>();

    getters/setters.....

当我返回第二堂课时，我得到这样的东西：

{
    - acceptees: [1]
            0:  {
                organizerEmail: "org"
                participants: 45
                requestStatus: "ACCEPTED"
                roomName: "plt-2828"
            }
    - autres: [2]
            -0:  {
                organizerEmail: "org"
                participants: 2
                requestStatus: "WAITING"
            }
            -1:  {
                organizerEmail: "org"
                participants: 3
                requestStatus: "WAITING"
            }
}

以下是我返回的方式

    @GET
    @Path("/{email}")
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes({ "text/plain, text/html" })
    public RequestByEmailDisplay displayByEmail(@PathParam("email") String email) {
        List<Request> requests = requestService.displayByEmail(email);
        RequestByEmailDisplay requestByEmailDisplay = new RequestByEmailDisplay();
        requests.forEach(request -> {
            if (request.isAccepted()) {
                requestByEmailDisplay.getAcceptees().add(request.buildById());
            }
        });
        requests.forEach(request -> {
            if (!request.isAccepted()) {
                requestByEmailDisplay.getAutres().add(request.buildById());
            }
        });
        return requestByEmailDisplay;
    }

这就是我想要的......除了它显示列表的大小以及每个元素的索引这一事实。

EDIT 我正在使用Jersey / Jackson并使用@Produces(MediaType.APPLICATION_JSON)

直接将其返回到我的资源中

有谁知道为什么以及如何删除它？
