[Resolvido] Problema com Convereter

tiago_ · Setembro 13, 2013, 9:36am

Pessoal, tenho esse converter aqui:


@FacesConverter(value ="motoristaViaturaConverter")

public class MotoristaViaturaConverter implements Converter {

	 @Override    
     public Object getAsObject(FacesContext ctx, UIComponent component,    
             String value) {    
         if (value != null) {    
             return component.getAttributes().get(value);    
         }    
         return null;    
     }    
     
     @Override    
     public String getAsString(FacesContext ctx, UIComponent component,    
             Object obj) {    
         if (obj != null && !"".equals(obj)) {    
             String id;    
             try {    
                 id = this.getId(getClazz(ctx, component), obj);    
                 if (id == null) {    
                     id = "";    
                 }    
                 id = id.trim();    
                 component.getAttributes().put(id,    
                         getClazz(ctx, component).cast(obj));    
                 return id;    
             } catch (SecurityException e) {    
                 e.printStackTrace();    
             } catch (IllegalArgumentException e) {    
                 e.printStackTrace();    
             } catch (NoSuchFieldException e) {    
                 e.printStackTrace();    
             } catch (IllegalAccessException e) {    
                 e.printStackTrace();    
             } catch (ClassCastException e) {    
                 e.printStackTrace();    
             }    
         }    
         return null;    
     }    
     
     private Class<?> getClazz(FacesContext facesContext, UIComponent component) {    
         return component.getValueExpression("value").getType(    
                 facesContext.getELContext());    
     }    
     
     public String getId(Class<?> clazz, Object obj) throws SecurityException,    
             NoSuchFieldException, IllegalArgumentException,    
             IllegalAccessException {    
         for (Field field : clazz.getDeclaredFields()) {    
             if ((field.getAnnotation(Id.class)) != null) {    
                 Field privateField = clazz.getDeclaredField(field.getName());    
                 privateField.setAccessible(true);    
                 if (privateField.get(clazz.cast(obj)) != null) {    
                     return (String) field.getType()    
                             .cast(privateField.get(clazz.cast(obj))).toString();    
                 } else {    
                     return null;    
                 }    
             }    
         }    
         return null;    
     }    
 }

Ele eh chamado aqui:

...

	 <h:selectOneMenu id="itemSelecionado" value="#{controleBean.produtoMotorista.objetoMotorista}"
						converter="motoristaViaturaConverter" items="#{motoristaBean.listaNomeMotoristas}">
						
						
					<f:selectItem itemLabel="Selecione" itemValue="" />
						<f:selectItems 
							value="#{motoristaBean.listaNomeMotoristas}" 
							var="listaNomeMotoristas"
							itemValue="#{listaNomeMotoristas}" 
							itemLabel="#{listaNomeMotoristas.nome}" />
					</h:selectOneMenu>
		

...

Quando eu abro essa pagina ja da esse erro no console:

Tem isso aqui:

                   return (String) field.getType()    
                             .cast(privateField.get(clazz.cast(obj))).toString();

O pior q eu ja fiz isso com outra entidade e n tive problema:

Amigão eu posso estar errado… mas seu log esta dizendo "java.lang.ClassCastException
at java.lang.Class.cast(Class.java:2990) "

Então ele não conseguiu dar cast em algo, a linha que machado perguntou é de onde vem o erro.

Entao essa linha,

    return (String) field.getType()      
              .cast(privateField.get(clazz.cast(obj))).toString();

tem algo errado. Uma pergunta, porque você ta dando um toString e cast String ao mesmo tempo?? não me faz sentido

Entao amigo, peguei esse converter genérico (deveira rodar sem problmemas p qualquer entidade). Eu utilizo ele(o mesmo converter, so mudei o nome) com outra entidade e n tenho problemas.
Modifiquei a linha q tava o erro, ficou assim:

  return (String) field.getType().toString();

Agora ele so pega o mesmo objeto sempre, nao importa o item q eu escolha no selectOneMenu, ele sempre captura o mesmo obeto. Pelo menos estamos no caminho certo:)

Esse eh o objeto q ele sempre captura: viatura.motorista.Motorista@5b61116c
deve ser o o primeiro ou ultimo da lista.

mr.michels · Setembro 16, 2013, 3:27pm

eu só perguntei mesmo, o problema é isso aqui :

field.getType().cast(privateField.get(clazz.cast(obj)))

[quote=mr.michels]eu só perguntei mesmo, o problema é isso aqui :

Relaxa

Eh, o problema eh nessa linha, mesmo assim nao estou conseguindo resolver

tiago_ · Setembro 17, 2013, 10:19am

Eh pessoal, to tendo muita dificuldade p resolver isso. Alguma luz ?

mr.michels · Setembro 17, 2013, 10:30am

Amigão debuga aeeeee!
verifica se o problema ta no cast do field.getType().cast(), ou se ta no privateField.get(clazz.cast()). A partir dai fica mais fácil resolver…

Resolvido:

O campo codigo da Classe Motorista tava como int, o certo eh Integer:

private Integer codigo;

Cara, q raiva q eu to, perdi tanto tempo nisso…
Tb nem me culpo 100%, aqui na sala eh uma zuada da porra…

Muito obrigado pela ajuda !

Boas praticas sempre é bom. Os conceitos de variáveis primitivas e de referência são muito importante. Principalmente quando você quer instanciar como Object.
É nois sempre que precisar tamo ae!
