Configure ObjectMapper in JaxRS Whiteboard application https://liferay.dev/sv/c/message_boards/find_thread?p_l_id=119785294&threadId=120700158 2026-05-10T16:24:02Z 2026-05-10T16:24:02Z Andre Albert https://liferay.dev/sv/c/message_boards/find_message?p_l_id=119785294&messageId=120700579 2021-03-30T12:27:17Z 2021-03-30T12:27:17Z

<p>Ok, i realized that there was a osgi config file org.apache.aries.jax.rs.jackson.config existent, that automatically enables jackson objectmapper. This was the reason of my getSingletons ignored JsonProviders.</p> <p>Still, i am wondering who to configure the default json-provider (if used). But this is not critical for me anymore. </p>

<p>We are currently migration a 7.1 jaxrs application to 7.3 DXP. </p> <p>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).</p> <p>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</p> <p>Many thanks and greetings</p> <p>Andre</p>
