Introduced MappingContext.getPersistentPropertyPath(String, Class<?>) to allow looking up a PersistentPropertyPath from a plain dot-notated path expression (e.g. foo.bar.foobar). This removes the need to use a PropertyPath in case you really only want to look up plain path expressions and the additional functionality in PropertyPath (camel case traversal and interpreting _ as hard delimiter) is not needed or wanted.
Changed getPersistentEntity(PersistentProperty<?>) to return the actual type of the persistent property in order to deal with collection and map types transparently.
Original pull request: #31.
Reverted from ConcurrentHashMap to plain HashMap where concurrency wasn't an issue and profiling showed performance hotspots. Introduced caches for ParameterizedTypeInformation.getComponentType() and the resolved raw type in TypeDiscoverer.
BasicPersistentEntity now only caches the most concrete property for a by-name lookup to mimic the behavior that was implemented in getPersistentProperty(String name). This is to prevent shadowed properties of superclasses leaking into the by-name lookups.
Improved AbstractPersistentProperty.toString() to rather render the concrete field it is backed by.
This causes the configured persistent entities being added to the context on its initialization instead of a delayed initialization on ApplicationContext refreshed event.
So far we threw exceptions in case we find the same exception on getters *and* setters. We now allow this scenario in case the annotations are semantically equivalent.
AnnotationBasedPersistentProperty now caches direct annotations on construction but still tries to lookup an annotation as meta-annotation if not found in cache on later requests. Extended try/catch block in AbstractMappingContext.addPersistentEntity(…) to invalidate cache on exceptions during property creation as well.
