We are currently migration a 7.1 jaxrs application to 7.3 DXP.
Previously, we add JacksonJsonProvider to our getSingletons() result
to enable a pre-configured Jackson-JSON mapping. But using this in
Liferay 7.3 our preconfigurations of the mapper are not applied. Even,
if we dont not add the JacksonJsonProvier the object serialization
still works, so i guess there is a default object mapper somewhere
applied (in 7.1 we got the no-MessageBodyWriter exceptions in that case).
How can we adjust the default Jackson provider in out
application? The aim is to replace the LocalDate Serializer to
serialize dates to [yyyy, mm, dd] array
Many thanks and greetings
Andre
