Description
For client interactions, Spring Framework 7 introduces the hints() method on the RestClient to allow programmatically specifying hints to pass to the JacksonJsonHttpMessageConverter, as detailed in the Spring blog
For the server side, the Spring MVC documentation here specifies that MappingJacksonValue can be used to programmatically provide hints for serialisation in controller methods, however this class is deprecated and only supported by the Jackson 2 implementation.
This has been noted in this Stack Overflow thread without any clear resolution. There appears to be no convenient way to pass hints to the JacksonJsonHttpMessageConverter with Spring MVC from a controller method when using Spring 7 and Jackson 3.
Please can the implementation be updated to support MappingJacksonValue with Jackson 3, or documentation updated to detail how to pass hints programmatically in the controller method?
