问HTTP 400坏请求: javax.ws.rs.BadRequestException

EN

我创建了一个RESTful web服务，并编写了一个客户机来使用它。但是当我运行它时，我会使用HTTP400Bad请求: javax.ws.rs.BadRequestException exeption。这是我的客户代码：

    String webserviceURI = "http://localhost:8084/fsc-access";

ClientConfig clientConfig = new ClientConfig();
Client client = ClientBuilder.newClient(clientConfig);
URI serviceURI = UriBuilder.fromUri(webserviceURI).build();
WebTarget webTarget = client.target(serviceURI);
MultivaluedMap formData = new MultivaluedMapImpl();
formData.add("plate", plate);
formData.add("startTime", start.toString());
formData.add("endTime", end.toString());
Weightings weightings = new Weightings();
 weightings.getWeightings().addAll((Collection<? extends Weighting>) webTarget.path("rest").path("report").path("loadWeightingByPlate").
        request().accept(MediaType.APPLICATION_XML).post(javax.ws.rs.client.Entity.form(formData), Weightings.class));

这是我的web服务：

@Path("/report")
public class WeightingRESTfulService {

@POST
@Path("/loadWeightingByPlate")
@Produces(MediaType.APPLICATION_XML)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Weightings LoadWeightingInSpecTimeInSpecPlate(
        @FormParam("plate") String plate,
        @FormParam("startTime") String _startTime,
        @FormParam("endTime") String _endTime,
        @Context HttpServletRequest req) {
    Long startTime = new Long(_startTime);
    Long endTime = new Long(_endTime);
    try {
        Weightings weightings = new Weightings();
        weightings.getWeightings().addAll(Weighting.LoadWeightingInSpecTimeInSpecPlate(startTime, endTime, plate));
        System.out.println("no error");
        return weightings;
    } catch (Exception ex) {
        System.out.println("Exception = " + ex);
        return null;
    }
}
}

有人能帮我使用这个web服务吗？

有一些警告：
