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.
We now build against a newer Servlet API version to align with Spring Framework.
Also, introduce a version property servlet.version for centralized version management.
Closes#1951
The fix for DATAREST-1535 has changed the default allowed methods for CORS requests to a smaller set than we originally returned. This commit reinstantiates the default to be set to all HTTP methods, Spring Data repositories support by default.
Related tickets: DATAREST-1535.
Removed Java8PluginRegistry not in use anymore anyway. Same for RepositoryRestConfigurerAdapter. Deprecated legacy ResourceMappingUtils and its client code exposed in RepositoryRestConfiguration as it's also not considered anymore.
Slightly tweaked the configuration model to rather handle the CorsRegistry via RepositoryRestConfigurer.configureRepositoryRestConfiguration(…) rather than RepositoryRestConfiguration itself. That allows moving of Spring WebMVC as a dependency in the core module.
The original methods exposing access to the CorsRegistry are now still available in deprecated form to not break existing clients.
Follow-up ticket: DATAREST-1542.
We now use Spring's path prefix capabilities to apply Spring Data REST's base path to its mappings. This was previously implemented by tweaking the matching conditions.
We now also pick up Spring 5.3's PathPatternParser and apply that to the custom HandlerMapping implementations we register.
Moved DelegatingHandlerMapping into the configuration package to be able to keep it around in package scope.
Deprecated RepositoryRestConfiguration.getBaseUri() as we have only supported paths for quite a while now. Moved all client code to ….getBasePath() instead.
