GsonDataFormat "useList" option?
Hi All,
Is it possible to unmarshal a List of some type with the GsonDataFormat?
JacksonDataFormat has this options, and lots others, but not seeing any
such option for gson.
Thanks!

Solved the date parsing issue. Apparently gson can't handle OffsetDateTime
out of the box. Here's my solution:
Gson gson = new GsonBuilder().registerTypeAdapter(OffsetDateTime.class, new
JsonDeserializer() {
@Override
public Object deserialize(JsonElement jsonElement, Type type,
JsonDeserializationContext jsonDeserializationContext) throws
JsonParseException {
try {
if (type == OffsetDateTime.class) {
return OffsetDateTime.parse(jsonElement.getAsString(),
DateTimeFormatter.ISO_OFFSET_DATE_TIME);
}
}
catch (DateTimeParseException e) {
throw new JsonParseException(e);
}
throw new IllegalArgumentException("unknown type: " + type);
}
}).create();
gsonDataFormat = new GsonDataFormat(gson, new
TypeToken<List<MatchResult>>(){}.getType());

Hey Alex,
Thank you. It looks like this may work. I'm getting a separate gson
exception, but I believe it's because gson is expecting Birthdate to be an
object, not a string: Expected BEGIN_OBJECT but was STRING at line 1 column
271 path $[0].Person.Birthdate. Separate issue I'll look into.

Hi Jeremy,
It reminds me something, could you please try something like below:
https://github.com/apache/camel-quarkus/blob/master/integration-tests/dataformats-json/src/main/java/org/apache/camel/quarkus/component/dataformats/json/JsonDataformatsRoute.java#L58..L61
