json - GET 返回 500 Internal Server Error 的响应状态

Question

尝试调用 JSON Web 服务时出现异常。我是新手，我想知道我在哪里搞砸了。

例外

GET com.sun.jersey.api.client.UniformInterfaceException: GET http://www.mcruiseon.com:8081/mCruiseOnCarPool4All/carpool4all/AcceptedSubscriptionList/Request/143683759/-1087322127在 com 返回响应状态 500 Internal Server Error。 sun.jersey.api.client.WebResource.handle(WebResource.java:686) at com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74) at com.sun.jersey.api.client .WebResource$Builder.get(WebResource.java:507) 在 test.carpool4all.SingleProviderTest.testPost(SingleProviderTest.java:70)

Junit 客户端 (SingleProviderTest)

// AcceptedSubscriptionList
    service = client.resource(UriBuilder.fromUri(
                "http://localhost:8081/mCruiseOnCarPool4All/carpool4all/AcceptedSubscriptionList/Request/" + identityHash
                + "/" + journeyList[i].getProviderHash()).build());
            //Line # 70 Below
            SubscribeJourneyConcrete[] acceptdList = service.type(MediaType.APPLICATION_JSON).get(
            SubscribeJourneyConcrete[].class);
    assertNotNull(acceptdList);
    assertTrue(acceptdList.length > 0);

@Path("/AcceptedSubscriptionList")
public class AcceptedSubscriptionListService {
    private ClientSession clientSession ;
    private static final SessionManager sessionManager = SessionManager.getInstance() ;
    @Context
    UriInfo uriInfo;
    @Context
    Request request;

    @GET
    @Path ("Request/{identityHash}/{providerHash}")
    @Consumes({ MediaType.APPLICATION_JSON })
    @Produces({ MediaType.APPLICATION_JSON })
    public Response getJourneyList(@PathParam("identityHash") String identityHash,
        @PathParam("providerHash") String providerHash) {
    AcceptedSubscriptionListRequest request = new AcceptedSubscriptionListRequest(providerHash) ;
    AcceptedSubscriptionListResponse response ;
    clientSession = sessionManager.getClientSession(identityHash) ;
    clientSession.getSendQueue().sendRequest(request) ;
    try {
        response = (AcceptedSubscriptionListResponse)clientSession.waitAndGetResponse(request) ;
    } catch (WaitedLongEnoughException e) {
        return Response.serverError().build() ;
    } catch (UnableToResolveResponseException e) {
        return Response.serverError().build() ;
    }
    return Response.ok(response.getAcceptedSubscriberList()).build();
}

网络服务加载正常
