org.codehaus.jackson.JsonParseException: nieoczekiwany znak ('' (kod 65279/0xfeff)): oczekiwano prawidłowej wartości

Question

Mam do czynienia z dziwnym problemem, jestem bardzo nowy w systemie Android i Json. Ja spożywania relaksującego WCF, który pokazuje odpowiedzi json jak ten:

próbuję deserializować go do obiektu złożonego z Jackson 1.9.11.

więc używam

Gdzie RawResult jest klasa z szablonem i RawCatalogs swoją klasę z obiektów zagnieżdżonych, kiedyś poprawnie deserializowania odpowiedzi, ale teraz to pokazuje błąd w tytule.

Definicja klasy jest to (nie wiem, czy informacje o zagnieżdżonych klas jest potrzebne do pełnego wsparcia? Myślę, że bardzo dobrze odwzorowane je, po prostu będzie zamieszczać importants dla jasności)

Więc moje pytanie jest, dlaczego jest pokazywanie tego błędu? Szukałem podobnych pytań na stackoverflow, wszystko wydawało się o błędzie kodowania, ale nie jest to ten sam błąd kodu, a także nie mam kontroli nad WCF.

Właściwie Jeśli skopiuję wklej Json Respone w this page, wygląda na dobrze uformowany.

Próbowałem również użyć mapper.configure ale żadna z cech Jsonparser pracował

Co robię źle?

Answer 1

Wystąpił ten sam błąd podczas odczytu pliku JSON.

Zapewniamy, że otrzymasz odpowiedź z RESTful WCF bez tego początkowego 0xfeff lub usuniesz ją przed wysłaniem do parsera JSON. Może trim() może zdziałać ...
