org.codehaus.jackson.JsonParseException: Carattere imprevisto ('' (codice 65279/0xfeff)): è previsto un valore valido

Question

Sono di fronte a un problema strano, sono molto nuovo per Android e Json. Sto consumando una WCF RESTful che mostra una risposta JSON come questo:

{"StatusCode":200,"Message":"","Result":{"Agencies":[],"Areas":[{"id":11,"area_name":"area 10","description":"updated 10","active":true},{"id":12,"area_name":"Area 11","description":"temp

Sto cercando di deserializzare ad un oggetto complesso con Jackson 1.9.11.

per cui uso

Dove RawResult è una classe con un modello e RawCatalogs sua una classe con oggetti nidificati, ha usato per deserializzare correttamente la risposta, ma ora sta mostrando l'errore nel titolo.

La definizione delle classi è questo (non so se sono necessarie informazioni delle classi nidificate per un pieno supporto? Credo che le ho tracciato molto bene, solo andando a postare le importants per chiarezza)

import org.codehaus.jackson.annotate.JsonCreator; 
import org.codehaus.jackson.annotate.JsonIgnore;

    {

     _Result = BuildGeneric(oClass); 
     _Status = false; 

    }

     _Status = StatusCode == 200; 
    }

Quindi la mia domanda è per questo che sta dimostrando che l'errore? Ho cercato domande simili sullo stackoverflow, tutto sembrava relativo a un errore di codifica, ma non è lo stesso errore di codice e inoltre non ho il controllo sulla WCF.

In realtà Se si copia incolla il Json Respone in this page sembra ben formato.

Ho anche provato ad utilizzare il mapper.configure ma nessuna delle caratteristiche di Jsonparser lavorato

Che cosa sto facendo di sbagliato?

Answer 1

Ho ricevuto lo stesso errore durante la lettura di un file JSON.

O si garantisce di ricevere una risposta dal WCF RESTful senza questo 0xfeff iniziale o lo si spoglia prima di inviarlo al parser JSON. Forse trim() potrebbe fare il trucco ...
