Are @wendal added to the corresponding field or entity, or is it?

Wendal 3/F • 353 days ago

Isn't @qq_640d75e3 talking about the return of the Ingress method?

king666 (QQ_640D75E3) 4 floor • 353 days ago

@wendal the entity class

king666 (QQ_640D75E3) 5 floor • 353 days ago

@wendal like Jackson's @jsoninclude.

Entity does not have this configuration

Json.tojson method.

Json.toJson(obj, JsonFormat.full());

I added the @ok ("Json:full") after the null field is still not displayed
