Serializar array elemento null[Resolvido]

ola a todos
seguinte estou usando o DataTable.net, vraptor (341) e hibernate.
quando serializo a lista e tem elementos nulo da erro de java.lang.NullPointerException, sem elementos nulos funciona normal.
andei pesquisando ate achei uma discussão sobre isso no github mas sem solução.
tentei assim ArrayList<ArrayList<Object>> objectListados = new ArrayList<ArrayList<Object>>();
e assim ArrayList<Object[]> objectListados = new ArrayList<Object[]>();
ambos dão erro.

uma solução que encontrei e varrer a lista ou vetor e vendo aonde ta nulo e colocar string vazia “”, mas é bizarro, como é comun acontecer isso acho que deve ter uma solução real para isso.

obrigado gente

segue o codigo

ArrayList<ArrayList<Object>> objectListados = new ArrayList<ArrayList<Object>>();
		
		ArrayList<Object> o = new ArrayList<Object>();
		ArrayList<Object> x = new ArrayList<Object>();
		
		o.add("1.1");
		o.add("1.1");
		o.add("1.3");

		x.add("2.1");
		x.add(null); /* aqui com valor funciona mesmo que seja ""*/
		x.add("2.3");
		
		objectListados.add(o);
		
		objectListados.add(x);
		
		DataTableModel dtModel = new DataTableModel();  
	    
	    dtModel.setsEcho(new Long(new Date().getTime()).toString());  
	    
	    dtModel.setiTotalRecords(objectListados.size());  
	    
	    dtModel.setiTotalDisplayRecords(100);  

	    dtModel.setAaData(objectListados.toArray()); 
	    
	    
	    result.use(Results.json()).withoutRoot().from(dtModel).include("aaData").recursive().serialize();

Eu faço algo parecido... Mas a minha dtModel tem o atributo aaData como uma List de List<String> ou seja, não uso Object...

Talvez isso possa resolver...

Olha como eu implementei:

public class DataTablesResult {

	private String sEcho;
	private List&lt;List&lt;String&gt;&gt; aaData = new ArrayList&lt;List&lt;String&gt;&gt;();
	private long iTotalRecords = 0;
	private long iTotalDisplayRecords = 0;

	public DataTablesResult(ResourceBundle bundle, String sEcho,
			List&lt;? extends DataTables&gt; list, long iTotalRecords,
			long iTotalDisplayRecords) {
		this.sEcho = sEcho;
		this.setAaData(list, bundle);
		this.setiTotalRecords(iTotalRecords);
		this.setiTotalDisplayRecords(iTotalDisplayRecords);
	}

	private void setAaData(List&lt;? extends DataTables&gt; list,
			ResourceBundle bundle) {
		if (list == null)
			list = new ArrayList&lt;DataTables&gt;();

		for (DataTables item : list)
			aaData.add(item.toListString(bundle));
	}

	private void setiTotalRecords(long iTotalRecords) {
		if (iTotalRecords &gt; 0)
			this.iTotalRecords = iTotalRecords;
	}

	private void setiTotalDisplayRecords(long iTotalDisplayRecords) {
		if (iTotalDisplayRecords &gt; 0)
			this.iTotalDisplayRecords = iTotalDisplayRecords;
	}
}

public class Customer implements DataTables {

	@Id
	@Column(name = &quot;SFC&quot;, columnDefinition = &quot;char&quot;)
	private String code;

	@Column(name = &quot;NAME&quot;, length = 255)
	private String name;

	@Column(name = &quot;CNPJ&quot;, length = 15, columnDefinition = &quot;char&quot;)
	private String cnpj;

	@Override
	public List&lt;String&gt; toListString(ResourceBundle bundle) {
		List&lt;String&gt; list = new ArrayList&lt;String&gt;();

		list.add(code);
		list.add(name);
		list.add(cnpj);

		return list;
	}

public interface DataTables {
	public List&lt;String&gt; toListString(ResourceBundle bundle);
}

Assim, eu só implemento a interface no modelo e cada entidade fica responsável por retornar os dados necessários...

opa bzla.
então meu problema é que uso hibernate, e ele devolve uma lista deste tipo assim ArrayList<Object[]>, quando realiza consulta especificando os campos.
e ai dentro de Object[] pode vir nulos

Rafael_Guerreiro 28 de fev. de 2013

Eu também uso Hibernate…

E eu tenho somente 1 Controller e 1 DAO para tratar dessas tabelas… Mas a estrutura é bem mais complexa, se você quiser, eu posso te mostrar aqui…

Salsicha 28 de fev. de 2013

nossa fico feliz.

por outro lado tava pensando em se era possível sobrescrever algum metódo o xstream para tratar isso.

Lucas_Cavalcanti 1 de mar. de 2013

onde acontece o NullPointerException? qual é a stack?

Salsicha 1 de mar. de 2013

ola
ele fala da @intercept porem nao condiz já coloquei accepts false em todas.

hql do hibernate
select tb0A.codigo, tb1A.nomePessoa, tb0A.email, tb0A.ramal, tb0A.ativo, tb0A.id from Senha as tb0A join tb0A.pessoa as tb1A where tb0A.ativo=:tb0Aativo

sql que o hibernate criou
Hibernate: select senha0_.codigo as col_0_0_, pessoa1_.nome as col_1_0_, senha0_.email as col_2_0_, senha0_.ramal as col_3_0_, senha0_.ativo as col_4_0_, senha0_.id as col_5_0_ from tbsenha senha0_ inner join tbpessoa pessoa1_ on senha0_.tbpessoa_id=pessoa1_.id where senha0_.ativo=?

segue o metodo
o parametro vem direto do hibernate query.list

public void getJsonDataTable(List<Object[]> objectListado, Result result) {

//		fiz essa gambi e funfa, mas so pra nao parar desenvolvimento
/*                   for (int i=0; i< objectListado.size(); i++){
			Object[] o = objectListado.get(i);
			for (int j = 0; j<o.length; j++){
				if (o[j] == null){
					o[j] = "";
				}
			}
		}
		*/
            DataTableModel dtModel = new DataTableModel();  
	    dtModel.setsEcho(new Long(new Date().getTime()).toString());  	    
	    dtModel.setiTotalRecords(objectListado.size());  	    
	    dtModel.setiTotalDisplayRecords(100);  
	    dtModel.setAaData(objectListado.toArray());   	    
	    result.use(Results.json()).withoutRoot().from(dtModel).include("aaData").serialize();  // erro é aqui
	}

segue o erro nativo

valeuuuu

Lucas_Cavalcanti 2 de mar. de 2013

bom, a gente pode considerar isso como um bug do VRaptor…

cria uma issue lá por favor?

quick fix (não tão quick assim =():

crie uma classe igual a essa no seu sistema:

github.com

caelum/vraptor/blob/master/vraptor-core/src/main/java/br/com/caelum/vraptor/serialization/xstream/VRaptorClassMapper.java

package br.com.caelum.vraptor.serialization.xstream;

import java.util.Calendar;

This file has been truncated. show original

mude o método serializedClass para retornar null se o type vier null (ou “” se reclamar do null)

crie uma classe igual a essa:
https://github.com/caelum/vraptor/blob/master/vraptor-core/src/main/java/br/com/caelum/vraptor/serialization/xstream/VRaptorXStream.java, apontando para o seu classMapper

crie essa classe:

@PrototypeScoped
@Component
public class CustomXStreamBuilderImpl extends XStreamBuilderImpl {
   //...

   @Override
   public XStream jsonInstance() {
		return configure(new SuaVRaptorXStream(extractor, getHierarchicalStreamDriver()));
	}
}

isso deve funcionar… se não funcionar dá um toque… se preferir podemos corrigir no VRaptor e gerar um jar snapshot pra vc ir usando enquanto não sai a próxima versão, que acha?

Salsicha 4 de mar. de 2013

ola bom dia

Lucas tive um problema com a Custom, diz que o extractor não existe, ai coloquei ele como atributo da classe e setei ele no construtor ai funcionou em tempo de projeto.
em execução quis testar com todos os elemento não nulos pra garantir o que estava funcionando continua funcionando.
porem quando serializo volta só uns 3 campos do objeto.

o atributo Object[] aaData do dtModel não foi serializado apos a alteração.
result.use(Results.json()).withoutRoot().from(dtModel).include(“aaData”).serialize();

segue o JSON

{“sEcho”: “1362393582883”,“iTotalRecords”: 25,“iTotalDisplayRecords”: 100}

segue a custom com o atributo:

import com.thoughtworks.xstream.XStream;

import br.com.caelum.vraptor.interceptor.TypeNameExtractor;
import br.com.caelum.vraptor.ioc.Component;
import br.com.caelum.vraptor.ioc.PrototypeScoped;
import br.com.caelum.vraptor.serialization.xstream.XStreamBuilderImpl;
import br.com.caelum.vraptor.serialization.xstream.XStreamConverters;

@PrototypeScoped  
@Component  
public class CustomXStreamBuilderImpl extends XStreamBuilderImpl {  
   //...  
	
	private TypeNameExtractor extractor;
  
   public CustomXStreamBuilderImpl(XStreamConverters converters,
			TypeNameExtractor extractor) {
		super(converters, extractor);
		this.extractor = extractor;
	}

@Override  
   public XStream jsonInstance() {  
        return configure(new VRaptorXStream(extractor, getHierarchicalStreamDriver()));  
    }  
}

Lucas_Cavalcanti 4 de mar. de 2013

vc usou a sua implementação de VRaptorXStream?

como ela está?

Salsicha 4 de mar. de 2013

oi boa tarde, esta igual ao github. não alterei o fonte.
sei que o vetor com elementos diferentes de nulo funciona, ai fiz esse teste em cima dos fontes do gihub.
ai o json foi gerado sem o aaData…

qq coisa tamo ai

Lucas_Cavalcanti 4 de mar. de 2013

To achando que é mais fácil gerar um snapshot pra você, com essa correção, o que acha?

Salsicha 4 de mar. de 2013

pode ser !!!
eu só agradeço.

Lucas_Cavalcanti 5 de mar. de 2013

Testa com esse jar:
