o json gerado é esse:

[quote]{“cooperado_$$_javassist_9”: {
"@resolves-to": “cooperado”,
“cnpj”: 76890987689098,
“nome”: “jose da silva”,
“endereco”: “”,
“cidade”: “”,
“uf”: “”,
“email”: “”,
“telefone”: “(78) 9098-7790”,
“contato”: “”,
“situacao”: “A”,
“empresa”: {
“codigo”: 5,
“descricao”: “TESTE1”,
“situacao”: “A”
},
“motoristas”: [
false,
{
"@class": “cooperado”[/quote]

#2

Alguém tem idéia do que pode estar acontecendo?

#3

referencia circular…

evite-a excluindo o campo que dá essa referencia circular…

#4

vendo o objeto json gerado, como o que esta postado aqui no tópico eu não consegui identificar o que esta gerando a referência circular, alguma dica?

#5

vc tah serializando um proxy do hibernate…
vc tá usando a última versão do xstream? a 1.3.1?

#6

Na teoria não deveria ser um proxy, pois estou testando se existe antes de serealizar, como o código abaixo:

public void jaExiste(Cooperado cooperado){ Cooperado coop = this.service.obter(cooperado); if(coop != null && coop.getCnpj() > 0){ this.result.use(Results.json()).from(coop).exclude("motoristas").serialize(); } }

Sim, estou usando a ultima versão do xstream, a 1.3.1

#7

resolvi o problema da referencia circular, mais ainda o json não esta saindo correntamente.

Na documentação diz que o json ficaria parecido com isso:

[quote]{“cliente”: {
“nome”: “Joao”
}}[/quote]

Mais não é isso que esta acontecendo, o json gerado esta assim:

[quote]{“cliente_$$_javassist_2”: {
"@resolves-to": “cliente”,
“codigo”: 4,
“empresa”: {
“codigo”: 12,
“descricao”: “COOPERCARGA”,
“status”: “A”
},
“cnpj”: 30679645907,
“nome”: “”,
“status”: “A”,
“clientesCheckpoints”: [
false,
{
"@class": “cliente”[/quote]

Onde eu já mandei exluir todas as propriedades que eu não queria, e ainda assim esta gerando o objeto json com todas as propriedades.

#8

o problema que tá acontecendo é que o hibernate te manda um proxy do javassist qdo vc faz o select no banco (via session.get ou session.load)

o proxy tem campos a mais que acabam sendo serializados junto com a entidade… Vamos ver se conseguimos colocar algo no próprio VRaptor… já tem uma issue cadastrada:

desculpa a demora em responder isso

#9

Acho que temporariamente você pode criar um clone do seu objeto ou até mesmo fazendo um set via bean-utils. Algo como isso:

[code]Cliente cliente = [busca do banco];
Cliente clone = new Cliente();
clone.setId(cliente.getId());
clone.setNome(cliente.getNome());
…

result.use(Results.json()).from(clone).exclude(“motoristas”).serialize(); [/code]

#10

É garcia, a solução que estou usando temporiamente é essa que você postou acima. Apesar de não ser tão elegante, esta resolvendo o meu problema.

Como que faz para enviar um list JSON para o controller ? qual o formato do json ? como devo recebe-lo no controller ? obrigado.

#12

se estiver usando jquery dá pra tentar transformar o json em query string e mandar, ou usar a anotação @Consumes(“application/json”) no método do controller.

o formato é parecido com o formato da serialização, mas tem que ter obrigatoriamente o root com o nome do parâmetro que vc escolheu.

Amigo, anotei o método do controller da seguinte forma:

        @Consumes("application/json")
	@Path("/fones/salvar.json")
	public void salvarFone(List<Fone> fones){

da dando o seguinte ERRO:

&lt;html&gt;&lt;head&gt;&lt;title&gt;Apache Tomcat/6.0.26 - Error report&lt;/title&gt;&lt;style&gt;&lt;!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}--&gt;&lt;/style&gt; &lt;/head&gt;&lt;body&gt;&lt;h1&gt;HTTP Status 415 - Request with media type [application/x-www-form-urlencoded].

#14

como vc tá passando o json?

#15

esta indo neste formato:

{"fones": [{"fone.numero":"(034)3232-3232","fone.obs":"","fone.foneTipo.id":"1"},{"fone.numero":"(034)3434-3434","fone.obs":"","fone.foneTipo.id":"2"}]}
#16

estou enviando com o $.ajax do jQuery:

	 $.ajax({
	      type: 'post',
	      dataType: 'json',
	      data: fones,
	      url:URLSalvarFones,
	      success: function(objRetorno){
	    	...
              }
         )};
#17

se vc coloca o json no data, por padrão o JQuery vai tentar transformar o json em query string (dá uma olhada num firebug da vida pra ver o que acontece)

tem um option do ajax que muda o content type da requisição, tente colocá-lo como application/json

se o json for facilmente transformável em formencoded (queryString) tente fazer isso e tirar o @Consumes.

Lucas eu não entendi muito o que vc falou, não conheço esse “queryString” e nem “formencoded”…

Eu Estou usando esse mesmo ajax para inserir apenas um objeto como abaixo e esta funcionando certinho:

var funcaoMinisterio = {
				"funcaoMinisterio.nome":nome,
				"funcaoMinisterio.descricao":descricao,
				"funcaoMinisterio.ministerio.id":ministerioId,
				}

Porem não estou conseguindo enviar uma lista de objetos, segue abaixo o que apareçe no firebug, se vc tiver qualquer solução para passar uma lista de objetos via ajax é bem vinda.

Postar:

Parâmetrosapplication/x-www-form-urlencoded

{"fones": [{"fone.numero"...	
JSON
		
	
fones
	[Object { fone.numero="(234)3243-4234", fone.foneTipo.id="1", fone.obs=""}, Object { fone.numero="(234)3234-2342", fone.foneTipo.id="1", fone.obs=""}]

	Object { fone.numero="(234)3243-4234", fone.foneTipo.id="1", fone.obs=""}

Estamos quase lá !!!

Configurei o ajax dessa forma:

$.ajax({
	     contentType:"application/json; charset=utf-8", 
             type: 'post',
	     dataType: 'json',
	     data: data,
	     url:URL,
	     success: function(objRetorno){
	         ...
	      }
	  });

Agora o erro é outro:
