Removed the rejecting check for collections and maps and solely rely on the evaluation of the actual type for the ….isEntity() decision in AbstractPersistentProperty. This will cause collection and map properties also being inspected for persistent types as soon as the owner type gets added to the mapping context.
Cleaned up configuration setup. AuditingBeanDefinitionRegistrarSupport now exposes a getAuditingHandlerBeanName() method to determine the bean name to be used for the AuditingHandler.
Previously we directly threw a MappingException in MappingContext.getPersistentEntity(TypeInformation) when the MappingContext was in strict mode and we were given a TypeInformation for which we didn't have a PersistentEntity already.
We now first check whether we should actually create a PersistentEntity for the given TypeInformation if no PersistentEntity is available, before throwing a MappingException - if we should not then we simply return null (e.g. for simple types like Integer or Double).

Added array checks to AbstractRepositoryMetadata.getReturnedDomainClass() to detect array component types. QueryMethod now considers methods returning arrays to be collection query methods.
Introduced a Slice interface which is effectively a Page without the total page information. This will allow store modules to implement slice-by-slice access without having to calculate a total number of elements.
Extracted content and Pageable related functionality into a common Chunk class which serves as base class for the two concrete implementations SliceImpl and PageImpl. Deprecated hasNextPage() etc. on Page in favor of the generic hasNext() methods.
QueryMethod now exposes an isSliceQuery() to indicate a query method will need sliced execution.
Added MappingContext.getManagedTypes() as well as ….hasPersistentEntity(Class) to access all types currently managed by the MappingContext and find out whether a type is managed by the context.
RepositoryConfigurationSupport now has a getAttribute(String) method to lookup String attributes on XML elements and annotations. The XML implementation converts the given attribute name in a lower-case, dashed representation for the lookup.
RepositoryConfigurationExtensionSupport now ha a generic postProcess(…) method to allow implementations that only need to work with String attributes unify their customizations into that single method.
Added AnnotatedTypeScanner to easily scan for annotated types within a set of base packages. Picks up interfaces by default which had to be customized when using ClassPathScanningCanidateComponentProvider.
Added DirectFieldAccessFallbackBeanWrapper that will use direct field access for beans in case no accessor method can be found. This allows to easily implement bean property values through accessors first but using the field directly if the accessors aren't available.
Introduced AnnotationDetectionMethodCallback to easily find methods equipped with a given annotation.
Added a Spring Data specific CollectionFactory that augments Spring's CollectionFactory with support for special collection types like EnumSet and EnumMap. For all other types we delegate to the wrapped class.
If a Converter handed into DefaultPersistentPropertyPath.toDotPath(…) returns null or an empty string for a mapped property name, that value is skipped during path construction.
We now skip bridge methods for query method processing in order to circumvent the changed behavior of Class#getMethods() in Java 8 (when the code was compiled with target byte code level 1.8). On Java 8 this results in bridge methods being found and inspected for query method annotations. Since we currently cannot analyze generic return types of bridge methods this results in NullPointerExceptions being thrown at a later stage in AbstractRepositoryMetadata#getReturnedDomainClass(…).

Related issue: DATAJPA-465.
Previously the map value type resolving algorithm checked the value type to be of type Map again to shortcut the resolution. We now weakened this to an assignment check and eagerly resolve the generic type if its bound on exactly that level already. If no concrete type argument can be found, we fall back to the general generics resolution mechanism.
The changes in 899cf25 causes Repositories not finding any repository instances in case the lookup of beans by type for RepositoryFactoryInformation if the initialization causes as cyclic reference. Even worse, we might run into cases in which the attempt to access the beans by type causes transitive object creation which results in a successful lookup on a second attempt.
This is effectively caused by the catch-block in DefaultListableBeanFactory.getBeansOfType(…) which registers the suppressed exception as the method is used for lookup the beans for injection points with Lists and Maps.
We now explicitly look for bean names first and access the bean by name afterwards, which guarantees the exception to be thrown if it occurs. This will reveal the underlying issue and let user potentially deal with it. It's generally recommended to refer to Repositories in a very lazy fashion (using Provider<T>, ObjectFactory<T> or @Lazy on the injection point as of Spring 4) to avoid creating circular dependencies through by-type-lookups.
We now eagerly populate the repository factory information in Repositories to provide a read only view on the discovered repository information. Previously lookup operations could also change some maps that held information about the until then discovered repository meta data which could lead to ConcurrentModifcationExceptions in multi-threaded environments. Since we don't allow any modification after construction this won't happen anymore.
We also cache the computed RepositoryMetadata in RepositoryFactoryBeanSupport.

Changed Hateoas(Pageable|Sort)HandlerMethodArgumentResolver to use newly introduced TypeVariables abstraction to avoid having to deal with string representations manually.
The registered TemplateVariables carry a "pagination.….description" key to be resolved against a MessageSource.
Moved getCrudMethods() to RepositoryMetadata to be able to add a isPagingRepository() to the interface as well. Changed DefaultCrudMethods to work with a RepositoryMetadata instead of RepositoryInformation.
DefaultRepositoryInformation now completely delegates to the ResourceMetadata given and not extend it to avoid initialization order issues.
In case of an unresolvable generic parameter in TypeDiscoverer's getTypeArgument(…) we check for a generic super type for the given bound and fall back to Object in case we find a parameterized type.
RepositoryConfigurationDelegate allows to easily trigger repository BeanDefinitions to be registered independently of the client API (XML or annotation configuration support). Refactored the existing configuration base classes to use the newly introduced class. Removed defaulting of infrastructure components needed for Spring 3.1 compatibility.
The Hateoas(Pageable|Sort)HandlerMethodArgumentResolver now receive a UriComponents instance to inspect for existing query parameters. They then refrain from adding template variables for already present parameters. Slightly modified the way the sort parameters is appended to the pagination properties (although semantically equivalent).
We now handle an IllegalArgumentException being thrown in case we deal with a templated request mapping. We simply skip the attempt to eagerly resolve the base URI for the request and rely on the assembler being capable of resolving it itself or the user effectively providing a Link instances to one of the toResource(…) overloads.
PagedResourcesAssembler now adds a LinkTemplate to every PagedResources instance created and pulls the template variable information from the registered resolvers for Pageable and Sort.
Extended PageableResourceAssemblerArgumentResolver to create a special MethodParameterAwarePagedResourcesAssembler so that the assembler will take qualifier information into account when being injected into controller methods.
Upgraded to Spring HATEOAS 0.9.0.BUILD-SNAPSHOT to be able to benefit from new methods added to MethodParameters as well as the LinkTemplate class. Updated Sonargraph architecture definition to allow the web layer to access logging.
Turned the static cache of RepositoryInformations in RepositoryFactorySupport into a non-static one to avoid the instance from potentially surviving redeployments in web app scenarios.
We now also set a resource pattern on the ClassPathScanningCandidateComponentProvider to limit the scanning for custom implementations even more and thus avoid reading a lot of unnecessary class files.
The CDI extension now eagerly instantiates repository beans that are annotated with the newly introduced @Eager annotation. This is necessary to prevent the initialization procedure from interfering with potentially already executed business logic.
To achieve this CdiRepositoryExtensionSupport provides a new method registerBean(…) that has to be called by store implementations. The extension will then keep track of beans that require eager initialization and trigger it when the container has finished validation.
Changed the design of RepositoryBeanDefinitionBuilder to receive stable dependencies in the constructor and the moving parts as method arguments. This enables us to reuse the builder instance for the creation of all repository bean definitions. Most importantly that means we can use a single CachingMetadataReaderFactory instance which will avoid reading files again when looking for custom implementation classes.
Adapted clients for XML configuration and JavaConfig accordingly.
The auditing subsystem now supports the usage of JDK 8 date time types when running on Spring 4.0.1 or better. To achieve that switched to use the DefaultFormattingConversionService which registers the relevant converters needed. We also modified the SPI CurrentDateTimeProvider to return a Calendar instance as it carries time-zone information to be able to convert the instance into time-zone based JDK 8 date/time types.
This also allows us to make the use of JodaTime optional and only rely on it in case of the usage of Auditable or any of the JodaTime types used in the annotation based scenario. Added support to set LocalDateTime as well.
Removed the unnecessary type arguments for AuditingHandler so that the setter taking an AuditorAware<T> can be successfully wired against implementations other than AuditorAware<Object> with Spring 4. The type argument was superfluous anyway as internally the type wasn't referred to and the handler is not used on a by-type basis.
We're now replacing the sort parameter for the URI to be created instead of simply appending them to the source URI to prevent previously applied sort parameters to be taken forward.
The PageableHandlerMethodArgumentResolver and SortHandlerMethodArgumentResolver now transparently ignore invalid values provided for page number, size and sort. We fall back to ignore the invalid values (for sort) and fall back to the defaults where appropriate (page number and size).
Used and adapted test cases from pull request #48.
Previously we did only support ordering by a string or property path through Sort. In order to be able to express more type safe ordering expressions we introduce QSort as a subclass of Sort that is able to wrap QueryDSL OrderSpecifiers. To be able to separate the concerns of sorting via QueryDSL expressions better we introduce the AbstractPageRequest base class and QPageRequest as a special implementation that accepts a QSort or OrderSpecifiers for ordering.
Original pull request: #59.
We now resolve the domain and id-types eagerly within the constructor of AbstractRepositoryMetadata implementations to prevent a RepositoryMetadata instance to be created in an invalid state. Pulled-up repositoryInterface property to AbstractRepositoryMetadata.
Original pull request: #58.
Suppress deprecation warnings for GenericTypeResolver for now. Added Simple(Property|Association)Handler to ease working with untyped PersistentProperty instances without having to fall back to raw types. Polished Sonargraph architecture description.
Pulled up the method declaration from AnnotationBasedProperty as it's useful to be able to inspect a property for annotations being configured on it independently from whether the persistent mapping of it has been defined via annotations or not.
Expose isAnnotationPresent(…) as well to ease quick checks for an annotation.
