Prezados tenho um projeto que utiliza o Xstream e Vraptor
tenho um payload que é um obj contendo uma lista de outros obj de tipos diferentes. a lista é de amounts… Ex:
{
"obligationToPay": {
"@resolves-to": "obligationToPay",
"id": 1,
"lastObservation": "last",
"amounts": [{
"id": 18,
"amount": "100.00"
}],
"account": {
"id": 19,
"number": "132"
},
"paymentType": "DEPOSIT_ACCOUNT"
}
}
Quando envio o json para o controller:
@Consumes
@Put("/obligationsToPay/{id}")
public void update(ObligationToPay obligationToPay) {....
recebo:
com.thoughtworks.xstream.converters.ConversionException: id : id : id : id

é um problema de conversao do xstream … alguem ja passou por isso? para deserealizar funciona normalmente…
abrass
o problema é que o cara que deserializa o json é diferente do que serializa, dentro do xstream, então não necessariamente dá pra deserializar um objeto que vc serializou com ele.
tenta mandar o json sem o amounts, pra ver se funciona… se sim, tenta ver se o formato não é um pouco diferente
oi lucas, sem o amounts sai do mesmo jeito, apenas sem a coleção
{
"obligationToPay": {
"@resolves-to": "obligationToPay",
"id": 1,
"lastObservation": "last",
"account": {
"id": 19,
"number": "132"
},
"paymentType": "DEPOSIT_ACCOUNT"
}
}
assim ele deserealiza normalmente, porém da erro na minha validação pois preciso da coleção.
abrassss
qual é o tipo da lista amounts?
é um tipo que eu mesmo criei
@Audited
@Entity
public class Amount {
@Id
@GeneratedValue
private Long id;
// Amount informed in payment
@Column(precision = 15, scale = 2)
@NotNull(message = "Informe o valor.")
private BigDecimal amount;
// Amount updated for payment
@Column(precision = 15, scale = 2)
private BigDecimal updatedAmount;
@OneToOne
@NotNull(message = "Informe o tipo do valor.")
private AmountType type;
public Amount(BigDecimal amount, AmountType type) {
this.amount = amount;
this.type = type;
}
public Amount() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public BigDecimal getAmount() {
return amount;
}
public void setAmount(BigDecimal amount) {
this.amount = amount;
}
public BigDecimal getUpdatedAmount() {
return updatedAmount;
}
public void setUpdatedAmount(BigDecimal updatedAmount) {
this.updatedAmount = updatedAmount;
}
public AmountType getType() {
return type;
}
public void setType(AmountType type) {
this.type = type;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((id == null) ? 0 : id.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Amount other = (Amount) obj;
if (id == null) {
if (other.id != null)
return false;
} else if (!id.equals(other.id))
return false;
return true;
}
public Boolean isUpdated() {
return updatedAmount != null;
}
}
abrasss
tudo bem, mas na classe obligationsToPay o campo amounts está declarado como List?
acho que ele espera que o campo no json esteja assim:
"amounts": [{ "amount": {
"id": 18,
"amount": "100.00"
}}],
tenta mudar pra isso e ver se funciona… se mesmo assim não funcionar tenta usar trocar esse primeiro amount pelo nome completo da classe
não sei se estou exagerando, mas que absurdo um negocio serializar de um jeito e deserealizar de outro… pqp rs
fiz das duas maneiras com o nome normal:
{
"obligationToPay": {
"@resolves-to": "obligationToPay",
"id": 1,
"lastObservation": "last",
"account": {
"id": 19,
"number": "132"
},
"amounts": [
{
"amount": {
"id": 18,
"amount": "100.00"
}
}
],
"paymentType": "DEPOSIT_ACCOUNT"
}
}

ops, errei ali em cima fiz com o json assim tb:
[code]
{
“obligationToPay”: {
"@resolves-to": “obligationToPay”,
“id”: 1,
"lastObservation": "last",
"account": {
"id": 19,
"number": "132"
},
"amounts": [
{
"br.com.fourdata.model.cco.amount": {
"id": 18,
"amount": "100.00"
}
}
],
"paymentType": "DEPOSIT_ACCOUNT"
}
}[/code]
---- Debugging information ----
message : br.com.fourdata.model.cco.amount : br.com.fourdata.model.cco.amount
cause-exception : com.thoughtworks.xstream.mapper.CannotResolveClassException
cause-message : br.com.fourdata.model.cco.amount : br.com.fourdata.model.cco.amount
class : br.com.fourdata.model.cco.ObligationToPay
required-type : java.util.ArrayList
line number : -1
-------------------------------
sim, tb acho um absurdo 
não era isso:
"br.com.fourdata.model.cco.amounts": [
{
"amount": {
"id": 18,
"amount": "100.00"
}
}
],
era isso:
"amounts": [
{
"br.com.fourdata.model.cco.Amount": {
"id": 18,
"amount": "100.00"
}
}
],
ou algo parecido
exato, corrigi da o erro acima.
Semanticamente falando, em rest, eu nao deveria mandar essa collection correto? abrass
dá o erro acima mesmo com o Amount maiúsculo? ou seja, o nome da classe mesmo.
bom, semanticamente depende vc está atualizando os amounts também? se sim, vc deveria passar sim.
tenta fazer um teste…
na classe ObligationsToPay, marque o atributo amounts com @XStreamImplicit e veja se funciona com o json inicial…
lucas, deu certo colocando
{
"obligationToPay": {
"@resolves-to": "obligationToPay",
"id": 1,
"deadline": "02/04/2012",
"status": "PENDING",
"included": "02/03/2012 15:06:42",
"lawsuit": {
"id": 16,
"processId": "Processo"
},
"creator": {
"id": 1,
"login": "renan",
"password": "renan",
"active": true
},
"lastObservation": "last",
"receiptCompliance": {
"id": 21,
"path": "path",
"originalName": "receipt.doc",
"extension": ".doc",
"size": "100.00",
"resterictedFile": true
},
"generationLawsuitTaskEnd": "PREPARATION_BOOK",
"amounts": [
{
"br.com.fourdata.model.cco.Amount": {
"id": 18,
"amount": "100.00"
}
}
],
"account": {
"id": 19,
"number": "132"
},
"paymentType": "DEPOSIT_ACCOUNT"
}
}
deu um erro antes pq devo ter errado em algo…
muito obrigado mesmo pela atenção.
Muito estranho esse comportamento não?!
vou tentar configurar isso com as anotações…
com relação a semantica, nao seria legal mandar a collection junto, concorda?
abrasss
se vc não pretende atualizá-la, não…
se vc está atualizando, o ideal seria só mandar aquilo que vai ser atualizado (embora vc devesse usar o método PATCH e não PUT ou POST) mas isso mais por causa de segurança mesmo, e no controller só atualizar os campos que vc esperava que fossem atualizados.
eheheh li o post assim que cheguei no trabalho.
PUT nao seria pra atualizar o meu objeto? pq PATCH?
uma ultima duvida, coloquei @XStreamImplicit no atributo amounts, dps tb tentei @XstreamAlias(“nomeQualificado”), e também tentei no meu customSerealization colocar:
xstream.alias("nomeQualificado", Amount.class);
mas nada fez os nós da lista vir com o nome.
alguma sugestao?
valeu lucas
abrasss
não é no customSerialization, e sim no deserialization…
ou vc tá tentando gerar o json já com o nome completo da classe?
vc tá com qual versão do VRaptor?
3.4.1-SNAPSHOT
estava fazendo na
public class CustomJSONSerialization extends XStreamJSONSerialization
o correto seria na serealização, pq eu pego o JSON, altero ele, dps envio de novo.
abrasss
tudo bem, mas vc poderia tentar resolver tb na deserialização, que é a parte que está dando problema, não?
estou tentando na deserealização.
O problema GRANDE é que em vários pontos do sistema, se eu pego um objeto serializado com um GET por exemplo, qdo dou um PUT, POST, ele não aceita o objeto.
O problema acorre também quando tento passar dois objs para um mesmo método. Por mais que eu crie um terceiro contendo os dois, faço um GET no terceiro, quando mando o mesmo json com PUT ou POST ele nao aceita.
Existe uma maneira de deixar esse comportamento padrão? Mesmo q trocando pra xml?
