Using spring-data-rest makes it impossible to configure the HATEOAS objectmapper [DATAREST-1072]

Casey Link opened DATAREST-1072 and commented

When you use spring-data-rest it uses the @EnableHypermediaSupport annotation, which makes it impossible to add jackson modules or features to the _halObjectMapper used by spring-hateoas.

This might be a bug on spring-hateoas, but the issues on github haven't received much attention over the years, so I'm posting it here because I narrowed it down to spring-data-rest that is causing the autoconfiguration of hateoas to be ignored (as per the spring boot docs).

My goals are as follows:

1. Use spring-data-rest
2. Also use spring-hatoas directly for cases where SDR doesn't fit
3. Add Jackson modules and features to the spring-hatoas ObjectMapper

As per the bug report on the hateoas project, in the lastest versions it is impossible to get a handle on the object mapper used by hateoas. The workarounds in that issue are no longer working, and using the default hateoas auto configuration is disabled by SDR

Affects: 2.6.3 (Ingalls SR3)
