Fala...
Estou tentando modificar a serialização json do vraptor a partir do XSTREAM, porem uma coisa estranha é que ele está me retornando a serialização do HashMap com um @ na frente.
Alguem poderia me ajudar. Segue os codigos abaixo.
public class DefaultMapConverter implements Converter {
@Override
public boolean canConvert(Class clazz) {
return Map.class.isAssignableFrom(clazz);
}
@Override
public void marshal(Object obj, HierarchicalStreamWriter writer, MarshallingContext context) {
writer.startNode("map");
Map<?,?> map = (Map<?,?>) obj;
for (Entry<?,?> entry : map.entrySet()) {
writer.addAttribute(entry.getKey().toString(), entry.getValue().toString());
}
writer.endNode();
}
@Override
public Object unmarshal(HierarchicalStreamReader arg0, UnmarshallingContext arg1) {
return null;
}
}
@Component
public class CustomJSONSerialization extends XStreamJSONSerialization {
private final HttpServletResponse response;
public CustomJSONSerialization(HttpServletResponse response,TypeNameExtractor extractor, ProxyInitializer initializer) {
super(response, extractor, initializer);
this.response = response;
}
/*public CustomJSONSerialization(HttpServletResponse response, TypeNameExtractor extractor) {
this.response = response;
this.extractor = extractor;
} */
@Override
public XStream getXStream() {
XStream xstream = super.getXStream();
xstream.registerConverter(new DefaultMapConverter());
return xstream;
}
}
public class MessageResult {
private final boolean success;
private final Map<String,String> attrs;
public MessageResult(boolean success) {
this.success = success;
this.attrs = new HashMap<String, String>();
}
public MessageResult with(String key, String value) {
this.attrs.put(key, value);
return this;
}
}
/*Controller*/
result.use(Results.json()).from(new MessageResult(true)
.with("message","ok")
.with("total", "x")).include("attrs")
.serialize();
/*Resultado*/
{"messageResult": {
"success": true,
"attrs": [
{
"@total": "x",
"@message": "ok"
}
]
}}
