Previously the SpEL expresssion created from JSON Patch path expressions were executed without double checking whether these paths actually exist on the target object in the first place. This is now in place.
Association links now explicitly indicate projections are available in case there are projection types registered for the association target type.
Original pull request: #273.
Switched from ProxyProjectionFactory.setResourceLoader(…) to ….setBeanClassLoader(…). Some generics polishing and removal of obsolete warnings supression.
We now also catch SpelEvaluationException in the attempt to set a null value for an expression as Spring 5 now reports a failed attempt (e.g. if the target type is not nullable) using that type whereas Spring 4.3 threw a NullPointerException.
Fixed the setup of our custom ExceptionHandlerExceptionResolver to conclude with a call to afterPropertiesSet() to make sure it's properly initialized.
We now expose the constructor that takes a RelProvider in RepositoryResourceMappings so that clients can tweak the default relation names. Changed the order of constructor parameters of (previously) non-public constructors for consistency.
The RelProvider to be used with the mappings can now be configured via RepositoryRestConfiguration and defaults to the EvoInflector based one.
When a PATCH call using JSON Patch tried to append an item to an empty collection, it previously failed to look up the type to unmarshal the incoming payload to. We now inspect the declared types on the wrapped object's property to determine that type for append operations.
Also, an uninitialized collection is now initialized using Spring's CollectionFactory.
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.
We now consider the base URI when resolving CORS configuration from repository interfaces. The base URI is now stripped from the request. Previously the base URI was not stripped from the request and was used to determine an exported resource.
