VRaptor + Hibernate + OneToMany

Quando estou trabalhando com um relacionamento OneToMany (no caso uma lista) com Hibernate o tipo na verdade por trás logo após uma consulta é o PersistentBag.
Na hora de transformar o objeto em json ocorre um erro de referencia circular porque o XStream não sabe trabalhar com o PersistentBag…

Para resolver o caso criei uma classe que extends XStreamJSONSerialization e sobrescrevi o método getXStream, dai surge minhas dúvidas:

O método getXStream está deprecated… Existe uma outra maneira de registrar o converter?
Existe uma maneira melhor para resolver tal situação?

tem sim, cria o converter e anota com @Component

não precisa mais sobrescrever o componente do VRaptor…

peterson.olbi 14 de out. de 2011

Lucas, eu implemento o Converter do VRaptor ou do XStream?

No caso de implementar o Converter do VRaptor como faria para enviar o list para o próximo na cadeia que sabe manusear o mesmo?

@Component
public class PersistentBagConverter implements Converter {
	
	@Override
	@SuppressWarnings("rawtypes")
	public boolean canConvert(Class type) {
		return PersistentBag.class == type;
	}

	@Override
	@SuppressWarnings("unchecked")
	public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) {
        context.convertAnother(new ArrayList<Object>((PersistentBag) source));
	}

	@Override
	public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) {
		return null;
	}

}

faça que nem nesse post:

http://www.wbotelhos.com.br/2010/08/26/vraptor-3-evitando-circularreferenceexception-do-xstream/

(a parte do collection converter)

só que a idéia é criá-lo como uma classe separada, anotada com @Component. Vc pode fazer assim:

@Component
public class PersistentBagConverter extends CollectionConverter {
            public PersistentBagConverter(XStreamBuilder builder) {
                  super(builder.jsonInstance().getMapper());
            }
            @Override
            @SuppressWarnings("rawtypes")
            public boolean canConvert(Class type) {
                return Collection.class.isAssignableFrom(type);
            }
}

Mas nesse caso como eu registraria o Converter com o XStream? O VRaptor não vez o registro automaticamente só pela a anotação @Component.

Lucas_Cavalcanti 14 de out. de 2011

vc tá com o VRaptor 3.4.0, certo?

vc usou o @Component do VRaptor?

vc apagou o customJSONSerialization que tinha criado?

peterson.olbi 14 de out. de 2011

package br.com.egm.filter;

import java.util.Collection;

import br.com.caelum.vraptor.ioc.Component;
import br.com.caelum.vraptor.serialization.xstream.XStreamBuilder;

import com.thoughtworks.xstream.converters.collections.CollectionConverter;

@Component
public class PersistentBagConverter extends CollectionConverter {

	public PersistentBagConverter(XStreamBuilder builder) {
		super(builder.jsonInstance().getMapper());		
	}

	@Override
	@SuppressWarnings("rawtypes")
	public boolean canConvert(Class type) {
		return Collection.class.isAssignableFrom(type);
	}
	
}

Estou com o VRaptor 3.4.0.
Eu apaguei o CustomJSONSerialization estou com apenas esse Converter no meu classpath.

Lucas_Cavalcanti 14 de out. de 2011

bom, se essa classe está junto com as classes da sua aplicação deveria funcionar sim… =(

tenta dar clean no projeto e no servidor, pode ser que as classes antigas ainda estejam no classpath.

peterson.olbi 14 de out. de 2011

Eu já realizei o clean, mas o VRaptor nem cria a instancia da mesma.

Se eu mudar o scope da classe para @ApplicationScoped o VRaptor reclama do construtor…

Os convertes que são registrados automaticamente implementam o Converter do VRaptor e possuem uma anotação em sua classe @Converter.

Lucas_Cavalcanti 14 de out. de 2011

na última versão ele registra os converters do XStream automaticamente também, ou pelo menos deveria…

qual servidor vc está usando? qual IDE? está iniciando a aplicação pela IDE?

peterson.olbi 14 de out. de 2011

Eclipse Indigo e Tomcat 6.0.23.

Lucas_Cavalcanti 14 de out. de 2011

tenta imprimir algo tanto no construtor quanto no canConvert da classe…

vc está serializando com result.use(json()).from(objeto).serialize()?

peterson.olbi 14 de out. de 2011

Estou usando ‘result.use(ExtJSJson.class).from(objeto).total(int).serialize();’.

Não imprimi nada… A instancia da classe nem é criada.

Lucas_Cavalcanti 14 de out. de 2011

ah, então é por isso… tenta com o json()… não lembro se o ExtJSJson está usando a infra nova de geração do json

peterson.olbi 14 de out. de 2011

Lucas lançou a exception quando troquei para o json():
