Java 8 LocalDateTime deserialized using Gson

Question

I have JSONs with a date-time attribute in the format \"2014-03-10T18:46:40.000Z\", which I want to deserialize into a java.time.LocalDateTime field using Gson.

When

Answer 1

Following worked for me.

Java:

Gson gson = new GsonBuilder().registerTypeAdapter(LocalDateTime.class, new JsonDeserializer() { 
@Override 
public LocalDateTime deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException { 

return LocalDateTime.parse(json.getAsString(), DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm")); } 

}).create();

Test test = gson.fromJson(stringJson, Test.class);

where stringJson is a Json which is stored as String type

Json:

"dateField":"2020-01-30 15:00"

where dateField is of LocalDateTime type which is present in the stringJson String variable.
