Vraptor + Rest + LocalDateTime[RESOLVIDO]

Lucas_Cavalcanti · Agosto 30, 2012, 10:31pm

não existem caused by’s na stacktrace?

ou pelo menos não aparece alguma classe sua nela?

vasilvei · Agosto 31, 2012, 7:23am

Lucas!

Na minha aplicação web eu uso tudo via json, qual o melhor para fazer a comunicação do desktop via xml ou json, porque eu tenho um serialization json e quando eu faço um post
de LocalDateTime funciona perfeitamente, o que eu teria que fazer para usar json

nessa parte aqui:?


 restfulie = Restfulie.custom();
        restfulie.getMediaTypes().register(new XmlMediaType().withTypes(Grupo.class, Produto.class, Item.class, Versaotabelas.class));

eu preciso dessa anotação nas classes se for usar json:

@XStreamAlias("versaopdvs")

A minha CustomXStreamJSONSerialization que funciona na parte web

troca o new XmlMediaType por new JsonMediaType…

ou use xml do lado do vraptor também

vasilvei · Agosto 31, 2012, 11:56am

Lucas eu sei que estou sendo chato cara, mas se por gentileza puder me dar uma ajuda, vou te explicar como esta o meu projeto.

Obs: estou fazendo novamente tudo em xml.

se eu mando um objeto que tem Atributo LocalDateTime da apl. web para desktop vai de boa.

quando eu mando um objeto do desktop para web via post, que não tem objeto LocalDateTime vai de boa. se for com LocalDateTime preenchido dá esse pau:

eu subscrevi o XStreamBuilder, na apl. web, ele passa por aqui quando estou debugando, eu coloquei o “ISO-8859-1”, porque estava dando : Invalid byte 2 of 4-byte UTF-8 sequence.

package br.com.coliseu.util;

		xStream.processAnnotations(new Class[] {Versaotabelas.class});
		xStream.registerConverter(new LocalDateConverter());

	}

}

Lucas_Cavalcanti · Agosto 31, 2012, 12:00pm

na api desktop vc tá registrando o converter das datas também?

vasilvei · Agosto 31, 2012, 12:30pm

Para registrar no desktop é dessa forma, igual ao de web

package br.com.coliseu.util;

@Component  
public class XStreamBuilder extends XStreamXMLDeserializer {  
  
    public XStreamBuilder(ParameterNameProvider provider, br.com.caelum.vraptor.serialization.xstream.XStreamBuilder builder) {  
        super(provider, builder);  
    }  
  
  
/*    Extension point to configure your xstream instance. 
      @return the configured xstream instance 
*/  
       
    @Override  
    protected XStream getXStream() {  
        XStream xStream = new XStream(new DomDriver("ISO-8859-1"));  
        xStream.processAnnotations(new Class[] {Versaotabelas.class});  
        xStream.registerConverter(new LocalDateConverter());  
        xStream.registerConverter(new LocalDateTimeConverter());  
        return xStream;  
    }  
  
}

Eu registrei também aqui

        restfulie.getMediaTypes().register(new XmlMediaType().withTypes(Grupo.class, Produto.class, Item.class, Versaotabelas.class, LocalDateTimeConverter.class));

Mas continua dando:

lement type "org.joda.time.chrono.ISOChronology" must be followed by either attribute specifications, ">" or "/>".

Lucas_Cavalcanti · Agosto 31, 2012, 3:04pm

não é assim que registra o converter no restfulie…

vc precisa customizar o xstream de dentro…

restfulie.getMediaTypes().register(new XmlMediaType() {
   {withTypes(Grupo.class, Produto.class, Item.class, Versaotabelas.class)}

   @Override
   protected void configure(XStream xstream) {
      //registre o cara aqui.
   }
});

vasilvei · Agosto 31, 2012, 3:37pm

Então fiz isso no Desktop:

        restfulie = Restfulie.custom();
        
        
        restfulie.getMediaTypes().register(new XmlMediaType() {  
            {withTypes(Grupo.class, Produto.class, Item.class, Versaotabelas.class);}  

            @Override  
            protected void configure(XStream xstream) {  
               //registre o cara aqui.  
                xstream.registerConverter(new LocalDateConverter());
		xstream.registerConverter(new LocalDateTimeConverter());
            }  
         });

ele chama o LocalDAteTimeConverter agora do desktop:

/*

package br.com.arena.resources;

import org.joda.time.LocalDateTime;

public class LocalDateTimeConverter extends AbstractSingleValueConverter {


	@Override
	public boolean canConvert(Class type) {
		return LocalDateTime.class.equals(type);
    }

    @Override
    public String toString(Object obj) {
        try {

        return DateTimeFormat.forPattern("dd/MM/yyyy HH:mm:ss").print((LocalDateTime) obj);
        } catch (Exception e) {
            return "ERRO";
        }

    }
    @Override
    public Object fromString(String string) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

}

e chama a parte web.

		xStream.processAnnotations(new Class[] {Versaotabelas.class});
		xStream.registerConverter(new LocalDateConverter());
		xStream.registerConverter(new LocalDateTimeConverter());
		return xStream;

}

daí dá esse erro:

deve ser por causa disso

@Override  
    public Object fromString(String string) {  
        throw new UnsupportedOperationException("Not supported yet.");  
    }

Perfeito, foi falta de atenção minha, Valeu ai Lucas, tudo certo agora.

    @Override
    public Object fromString(String string) {
    	DateTimeFormatter fmt = DateTimeFormat.forPattern("dd/MM/yyyy HH:mm:ss");
    	return LocalDateTime.parse(string, fmt);

    }
