HTTP 400错误请求:javax.ws.rs.BadRequestException [英] HTTP 400 Bad Request : javax.ws.rs.BadRequestException
问题描述
我创建了一个RESTful Web服务，并编写了一个客户端来使用它.但是当我运行它时，我接受HTTP 400错误请求:javax.ws.rs.BadRequestException exeption.这是我的客户代码:
I create a RESTful web service and write a client to use it . but when I run it i take HTTP 400 Bad Request : javax.ws.rs.BadRequestException exeption . this is my client code :
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));
这是我的网络服务:
@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;
}
}
}
任何人都可以帮助我使用此Web服务吗?
can any one help me to use this web Service ?

推荐答案
您的资源正在返回Weightings的实例，因此您只需要强制转换它，而无需执行addAll()
Your resource is returning an instance of Weightings, so you just need to cast it, you don't need to do the addAll()
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));
应该是:
Weightings weightings = (Weightings) webTarget.path("rest").path("report").path("loadWeightingByPlate").
request().accept(MediaType.APPLICATION_XML).post(javax.ws.rs.client.Entity.form(formData), Weightings.class));
它不会解决您的400个异常，但是如果没有它，您将得到ClassCastException.
It won't fix your 400 exception, but you'll get a ClassCastException without it.
