I encountered a case where class level JsonSerializable annotation does not
require registration with Simple Module but method level does
<https://stackoverflow.com/questions/53864236/class-level-jsonserializable-annotation-does-not-require-registration-with-modul>
.
Here is the example I tried
@JsonSerialize(using = ItemRowSerializer.class )
private ItemRow tes
tItem(){
return new ItemRow("abc", Arrays.asList("item1", "item2",
"item3"));
}
I test it out like this
String jsonResult = new ObjectMapper().writeValueAsString(testItem());
System.out.println(jsonResult);
I noticed that jsonString did not serialize using ItemRowSerializer.
However, when I did this, it gave the expected jsonString
SimpleModule module = new SimpleModule()
module.addSerializer(ItemRowSerializer.class)
mapper.register(module);
String jsonResult = new ObjectMapper().writeValueAsString(testItem());
System.out.println(jsonResult);
On the otherhand, if I had my ItemRow class annoated with
@JsonSerializable, there was no need with module at all.
i.e
@JsonSerializable(using = ItemRowSerailizer
public class ItemRow<T> {...}
Since I am passing this serialized object over the wire, I do not prefer to
write to mapper and send string representation across.
how would I go about getting method level annotation working without module
registration?
for details on the actual serializer implementation, please refer here
