We now support using AggregateReference as type to bind request parameters taking URIs pointing to related aggregates. The default resolution will try to resolve the entire URI via UriToEntityConverter but one can also provide a function that can extract any part of the URI to be then resolved into either an identifier, aggregate instance or jMolecules Association against the ConversionService.
Fixes#2239.
The standard Spring MVC observability integration registers the plain request pattern for observations. For our repository controllers that would result in one pattern registered for all individual repository resources (e.g. /{repository}/{id} etc.). However, the insights users would like to gain rather follows the individual repositories exposed. That's why we have so far exposed repository specific path pattern (/myrepo/{id}) via a custom request attribute. To adhere to the new observability integration of Spring Framework 6, we need to expose that particular pattern on the ServerRequestObservationContext, too.
Fixes#2212.
LinkCollector is now an interface. The actual implementation has been moved to DefaultLinkCollector. RepositoryRestConfigurer now has a customizeLinkCollector(…) callback method to tweak or even completely replace the LinkCollector instance.
Fixes#2042.
Nested entities that contain a reference to an aggregate root get a link to that attached to their representation. Previously, the creation of those links assumed that the reference is a materialized instance of the remote aggregate. That's now altered to be able to deal with associations, use identifiers directly or materialize to an intermediate aggregate instance to potentially use a custom lookup.
The usage of text/uri-list as media type was entirely broken and not even advertised in the reference docs anymore. It's now again supported for both to-one and to-many associations via Collections. Maps are rejected as they cannot be rendered as list of URIs correctly. Updated reference documentation accordingly.
Added a custom MapModel implementation of RepresentationModel as apparently using Maps with EntityModel does not unwrap the content properly due to [0].

Correct a regression regarding association links. Introduce several test cases to prove this situation is fixed regarding PUTs for association links.
Source of the bug: 554d6cb27b (diff-1d7c16fe1992fef13a47fa8ab8599718L317) flips the criteria from "not single" to "single" without checking for related impacts.
We now rely on the MessageResolver capabilities of Spring HATEOAS to benefit of the optimizations in resource bundle resolution. Tweaked a couple of tests to make sure they properly use the resolver resorting to the default message the MessageResourceResolvable exposes.
The default exposure of repository methods is now controlled via RepositoryRestConfiguration.setExposeRepositoryMethodsByDefault(…). That allows us to remove the additional API from RepositoryDetectionStrategy as the mere detection is an orthogonal topic.
Also added RepositoryRestConfiguration.disableDefaultExposure() to set the RepositoryDetectionStategy to ANNOTATED and disables default method exposure in one go. That can be exposed via a Spring Boot configuration property downstream.
Additional cleanups in QuerydslAwareRootResourceInformationHandlerMethodArgumentResolver to make sure a QuerydslRepositoryInvokerAdapter is only applied if the QuerydslPredicateBuilder actually exposes a predicate. Extracted a couple of methods to make sure the mapping pipeline reads nicely.
Previously, when a request was sending an Accept header of some arbitrary *+json, the request was routed through the controllers and might have ended up producing a PersistentEntityResource that was then mapped using an uncustomized Jackson ObjectMapper. That has caused a huge JSON object to be unfolded which is highly undesirable.
We now only answer JSON requests to repository resources that contain an Accept header with any of the explicit JSON media types we got registered.
Tweaked the setup of the ExceptionHandlerExceptionResolver to not expose a bean in the first place but rather use the Spring MVC provided callbacks to register custom ones. We also now make sure MVC is bootstrapped property for integration tests through the inclusion of DelegatingWebMvcConfiguration.
The serializer for projection resources now also invokes ResourceProcessor instances registered for that particular projection.
Original pull request: #238.
Spring 4.3 returns Content-Type headers including the character encoding. We needed to relax our assertions on the content type headers to only check for compatibility.
Deprecated the ResourceProcessor invoking infrastructure in place here in favor of the types moved to Spring HATEOAS. Refactored our codebase to make use of these newly introduced types right away.

Upgraded to JSONPath 1.1.0 as 0.9 is not supported with Spring 4.2 anymore. Tweaked integration tests due to changed semantics and internals of JSONPath >= 1.0.
Extracted store specific tests into separate test modules to prevent classpath overlap between projects. Those tests are now executed in an "it" build profile to prevent the tests being packaged for distribution on release.
Use Map-based repositories and mapping contexts for test in the Core and WebMvc module.
Slightly changed the configuration API for lookup types on RepositoryRestConfiguration.
