did you inject object mapper in attributeConverter?

[Pihentagy]

No, I expected spring boot to do the magic, as I defined the custom ObjectMapper.

[Pihentagy]

Other settings seemed to work

[Pihentagy]

I have JsonDeserializer<PGpoint> and JsonSerializer<PGpoint>

[kqr]

hmm, how is that related to jpa?

[Pihentagy]

I have a json database field, and inside that json structure there is a PGpoint type field. (I know, its dumb)

I created this custom object mapper

@Component
class ObjectMapperInitializer {
    @Bean
    @Primary
    fun objectMapper(): ObjectMapper = JsonMapper.builder()
       // .. other options
       .build()
       // .. other options
       .registerModule(SimpleModule().apply {
            addDeserializer(PGpoint::class.java, PGpointConverter.PGpointDeserializer())
            addSerializer(PGpoint::class.java, PGpointConverter.PGpointSerializer())
    })
}

But seems like I misunderstood how to register custom serializers/deserializers

[kqr]

yes, but that's related to de/serialization process itself.
check this https://bootify.io/spring-data/hibernate-json-type.html or https://www.baeldung.com/hibernate-persist-json-object

[kqr]

depends on which version of hibernate you are using

[Pihentagy]

Ah, thanks, so basically

@Bean
fun jsonFormatMapper(objectMapper: ObjectMapper): HibernatePropertiesCustomizer =
    HibernatePropertiesCustomizer {
        it[AvailableSettings.JSON_FORMAT_MAPPER] = JacksonJsonFormatMapper(objectMapper)
    }

is the solution for Hibernate 6?

[kqr]

looks like

Maybe someday I won't need it anymore
