We have declared some Spring dependencies optional in the pom.xml file. I've changed the template.mf to declare the package dependencies of these artifacts as optional as well.
Added interfaces for common abstractions needed to implement historiography. A Revision is an entity associated with some RevisionMetadata. That in turn consists of a revision number and date at least and is backed by a implementation specific delegate. The Revisions wrapper class allows accessing the latest revision from a list of Revision instances no matter what order they are in. A RevisionRepository allows access the revision an entity was changed in the last time, access all Revisions of an entity as well as paged access to it.
Previously DomainClassConverter looked up the RepositoryInformation instances from the entire BeanFactory hierarchy but only looked the actual repository up from the current BeanFactory and not the entire hierarchy. Fixed and added test case.
In case a member class is not static the compiler will either create a constructor with a parameter of the enclosing type or alter the existing ones to add a first parameter of that type. Thus when instantiating the class we need to detect that case and hand in the parent object as parameter value.
Updated PreferredConstructor and Parameter abstractions to allow detecting this case as well as the ParameterValueProvider abstraction to capture the parent object.
DomainClassConverter now registers itself with the ConversionService handed into it. Added integration tests for lookup of RepositoryFactoryInformation.
PersistentEntity now has a isConstructorArgument(…) allowing to find out whether a PersistentProperty is referred to from a constructor argument. The PreferredConstructor abstraction now keeps track of the PersistentEntity it is built for and thus allows finding out whether a constructor Parameter maps a PersistentProperty.
Removed bean creation responsibility from BeanWrapper and introduced EntityInstantiator abstraction to allow the entity instantiation mechanism be short circuited via custom implementations. The reflection based implementation from BeanWrapper is now residing in ReflectionEntityInstantiator.
Fixed edge case scenario where the lookup for repository implementation classes picked up multiple classes if they ended with the same suffix (e.g. FooRepoImpl, AnotherFooRepoImpl). We're now expecting the classname to be an exact match but still allow nested packages. Changed the parser to reject multiple found implementation classes strictly now to at least avoid undiscoverable errors in case an ambiguity is popping up.
Added custom CDI extension to use repositories in a CDI environment. Base class picks up all Spring Data repository interfaces and allows working with qualifiers to bind beans to be created to qualifiers.
Introduced @ReadingConverter and @WritingConverter to allow to resolve disambiguates that might arise when implementing custom Converters.
Suppose we implemented a Converter<String, Class> and the store is able to handle both String and Class as native types. In this case there's no way to determine whether the converter shall actually be used to convert String properties into Class instances when writing or to create Class instances from Strings when reading. Thus the @ReadingConverter comes in handy in this case to tell the infrastructure to consider the converter for reading only.
Documented verify() to throw a MappingException in case verification fails. Let this exception flying cause the PersistentEntity already added to the cache be removed from it in turn.
Fixed execution of integration tests and tests in classes starting with Abstract* along the way. Upgraded to Mockito 1.8.5.
ClassTypeInformation now holds a cache for Class<?> to TypeInformation<?> mappings. It also exposes constants for Object, Collection, Set, List and Map TypeInformations.
We now use an exclusive upper bound of 4.0.0.RELEASE for Spring dependencies. With the snapshot repository removed we now get the latest release milestone to build on. Changed repository links to use http://repo.springframework.org to route dependencies through our Artifactory instance. Fixed some plugin dependency versions along the way.
