Come risolvere le definizioni di getter in conflitto per la proprietà in jackson

Ho alcune classi di modelli.Come risolvere le definizioni di getter in conflitto per la proprietà in jackson

public interface Product extends Serializable { 
    public Sku getDefaultSku(); 

    public void setDefaultSku(Sku defaultSku); 
} 

public interface Sku extends Serializable { 
    public Boolean isTaxable(); 

    public Boolean getTaxable(); 

    public void setTaxable(Boolean taxable); 
} 

public interface PremiumProduct extends Product { 
    public Long getProductCode(); 

    public void setProductCode(Long productCode); 
}

Le implementazioni di prodotti e Sku non possono essere modificate. Mi estendo solo dal prodotto. Successivamente, trasferisco l'oggetto JSON dal controller MVC di primavera. Il mio metodo di controllo è

@RequestMapping(value="/productDetail", method=RequestMethod.GET) 
    public @ResponseBody Product getCustomerName(@RequestParam String productUrl) throws Exception { 

     Product product = catalogService.findProductByURI(productUrl);  

       return product; 
    }

ho ottenuto seguenti eccezioni.

<h2>HTTP ERROR 500</h2> 
<p>Problem accessing /productDetail. Reason:

Quindi, come posso ottenere il mio JSON dal mio controller.

Si può cercare di ignorare isTaxable() ad esempio per risolvere il conflitto:

@JsonIgnore 
public Boolean isTaxable();

Cosa succede se non si ha accesso alla fonte? Come un oggetto da una lib di terze parti. –

In questo caso potresti utilizzare GSON lib http://code.google.com/p/google-gson/ –

Jackson Mix-In Annotations per il salvataggio!

Yap, sto bene con la soluzione annotaitons di Mix-in. –

Puoi provare anche a Genson lib. Per attivarlo in primavera è necessario registrare il convertitore di messaggi e quindi tutto dovrebbe funzionare.

Il mio problema è ok seguendo la soluzione secondo la risposta del programmatore Bruce.

ho scritto classe intermedia,

abstract class IgnoreSetValueMixIn {  
    @JsonIgnore public abstract Boolean getTaxable(); 
    @JsonIgnore public abstract Boolean isTaxable(); 
    @JsonManagedReference public abstract Sku getDefaultSku(); 
    @JsonBackReference public abstract Product getDefaultProduct(); 
}

Nel controllore,

@RequestMapping(value="/productDetail", method=RequestMethod.GET) 
    public @ResponseBody String getCustomerName(@RequestParam String productUrl, HttpServletResponse response) throws Exception { 
    ObjectMapper mapper = new ObjectMapper(); 

      mapper.getSerializationConfig().addMixInAnnotations(Sku.class, IgnoreSetValueMixIn.class); 
      mapper.getSerializationConfig().addMixInAnnotations(SkuImpl.class, IgnoreSetValueMixIn.class); 

return mapper.writeValueAsString(product); 
}

Per il problema simile ho provato con @JsonIgnore esso ha dato un messaggio di errore come com.fasterxml.jackson.databind. JsonMappingException: nessun serializzatore trovato per la classe org.citi.facility.GetterMethodsObject e nessuna proprietà scoperta per creare BeanSerializer (per evitare eccezioni, disabilitare SerializationFeature.FAIL_ON_EMPTY_BEANS)).

mio codice Simpel è

class GetterMethodsObject 
{ 
    public int getId(){ 
     return 10; 
    } 
    @JsonIgnore 
    public boolean isId(){ 
     return true; 
    } 
}
