Move to @PersistenceCreator as canonical annotation to explicitly express constructors and methods to be used to create domain object instances from persistence operations. Removed @FactoryMethod as it's not needed anymore. @PersistenceConstructor is now deprecated.
Renamed EntityCreatorMetadata(Support|Discoverer) to InstanceCreatorMetadata(Support|Discoverer) to avoid further manifestation of the notion of an entity in the metamodel as it's not used to only handle entities.
Issue #2476.
This is needed for downstream projects that attempt to merge persistent entity instances and previously didn't have a chance to detect that an object had to be set as-is instead of being merged recursively.
We now expose what type or PersistentEntity an association points to by trying to match the association's type to identifier types to entities. In case multiple matches are found, we require the user to explicitly declare the target type via @Reference.
Introduced PersistentEntities.of(…) for convenience.
Marked all packages with Spring Frameworks @NonNullApi. Added Spring's @Nullable to methods, parameters and fields that take or produce null values. Adapted using code to make sure the IDE can evaluate the null flow properly. Fixed Javadoc in places where an invalid null handling policy was advertised. Strengthened null requirements for types that expose null-instances.
Removed null handling from converters for JodaTime and ThreeTenBP. Introduced factory methods Page.empty() and Page.empty(Pageable). Introduced default methods getRequiredGetter(), …Setter() and …Field() on PersistentProperty to allow non-nullable lookups of members. The same for TypeInformation.getrequiredActualType(), …SuperTypeInformation().
Tweaked PersistentPropertyCreator.addPropertiesForRemainingDescriptors() to filter unsuitable PropertyDescriptors before actually trying to create a Property instance from them as the new stronger nullability requirements would cause exceptions downstream.
Lazy.get() now expects a non-null return value. Clients being able to cope with null need to call ….orElse(…).

Equipped @Persistent, @RepositoryDefinition and our Repository marker interface with @Indexed so that Spring 5's annotation processor will detect types annotated with or extending the aforementioned type for inclusion in the component index.

This commit introduces @ReadOnlyProperty to mark properties as not to be persisted. That trait is exposed via the newly added PersistentProperty.isWritable() which supersedes shallBePersisted(). Currently all non-transient property that are not annotated with @ReadOnlyProperty are considered writable.

Introduced @AccessType annotation to allow user to control the way property values are accessed. The default is field access. Improved the property detection mechanism to also inspect all PropertyDescriptors not backed by a field and add them if property access is defined for the property or type. We also keep property accessors for interfaces as they strongly indicate property access to be used (as they cannot be field backed by definition).
The BeanWrapper doesn't take a useFieldAccess attribute anymore as the access type is solely derived from the given PersistentProperty now. AnnotationBasedPersistentProperty now also rejects properties with the very same annotation both on the field and on an accessor.
Introduced new meta-annotation QueryAnnotation to mark and identify store specific Query annotations. This enables us to handle finder methods annotated with such store specific annotations in a generic way. Adjusted DefaultRepositoryInformation.getQueryMethods(…) to consider custom store specific query annotations.
