Java POJO与POJO到JSON的列表显示大小和索引

所以我有两个POJO：

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

    getters/setters.....

及

我是这样回来的

    @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。。。除了显示列表的大小和每个元素的索引之外

编辑 我正在使用Jersey/Jackson，并使用@ProducesMediaType.APPLICATION\u JSON直接将其返回到我的资源中

有人知道为什么以及如何移除它吗？

如何以及在哪里归还它？您使用什么来序列化对象？@mtyurt我使用Jersey/Jackson并直接在我的参考资料中返回@ProducesMediaType.APPLICATION\u JSON请发布您确切的JSON响应。第二个代码块不包含有效的JSON。这看起来更像YAML。
