Hi All,
I have written a custom de-serializer to ensure backward compatibility
between models and applied it on a field as below. I want the de-serializer
to kick-in if the JsonNode is array otherwise I want the default
deserializer to deserialize the field. I tried the below approach using the
ObjectMapper object but it is not working.
class Person {
private int id;
@JsonDeserialize(using = CustomDeserializer.class)
@JsonAlias("addresses")
private AddressDetails addressDetails;
// .Getter setters
}
but in *else* part jsonNode.asText() is returning empty string, but
debugger is showing child nodes. am I doing something wrong here?
@Override
public AddressDetails deserialize(...) {
AddressDetails addressDetails = new AddressDetails();
JsonNode jsonNode = jsonParser.getCodec().readTree(jsonParser);
AddressDetails addressDetails = null;
if(jsonNode.isArray()) {
// construct AddressDetails object
}
else {
ObjectMapper objectMapper = new ObjectMapper();
addressDetails = objectMapper.readValue(jsonNode.asText(),
AddressDetails.class);
}
return addressDetails;
}
Thanks
Govinda
