Use Jackson ObjectMapper improved default properties outside spring-web [SPR-12293]

[spring-projects-issues]

Sébastien Deleuze opened SPR-12293 and commented

It could be interesting to have an ObjectMapper builder outside spring-web and spring-webmvc modules (for example in messaging) in order to have the same Jackson default settings everywhere in Spring Framework. It is currently not directly possible since Jackson2ObjectMapperBuilder is in spring-web module.

Perhaps something to consider if we support in the future @JsonView in @MessageMapping annotated handler methods.

Another solution (even if less clean) could be to configure the same properties (DEFAULT_VIEW_INCLUSION and FAIL_ON_UNKNOWN_PROPERTIES to false) directly with the ObjectMapper instances in org.springframework.messaging.converter.MappingJackson2MessageConverter and org.springframework.jms.support.converter.MappingJackson2MessageConverter constructors.

From my perspective, simply setting the same properties on those internally created ObjectMapper instances isn't bad at all. I'd favor this little bit of repetition over a convoluted dependency structure.
