Removed the ability to configure a custom SpElExpressionParser for now as it's not really part of the performance optimization. Polished assertions in SpelEvaluatingMethodInterceptor.
Original pull request: #118.
We now allow a SpelExpressionParser to be configured on the SpelAwareProxyProjectionFactory. This parser is then passed on to SpelEvaluatingMethodInterceptor. We also now eagerly pre-parse any SpEL expression in @Value annotations on methods of the projection interface. This avoids repeated evaluations during the actual method invocations.

Introduced @SpringDataWebConfigurationMixing that can be used on configuration classes that are supposed to contribute components to the Application context when @EnableSpringDataWebSupport is used.
SpringDataWebConfigurationImportSelector scans the org.springframework.data package for classes annotated with that annotation and adds them to the classes to be considered config classes.
TrasnactionalRepositoryFactoryBeanSupport now exposes a setEnableDefaultTransactions(…) which, if disabled, causes the TransactionalRepositoryProxyPostProcessor not to be registered and thus no default transactions to be applied.

Extracted DefaultMethodInvokingMethodInterceptor from RepositoryFactorySupport and register it within ProxyProjectionFactory if the code is running on Java 8.

Primarily intended to be used with Distance instances, we introduce a Range value type. Distance now has factory methods to create Range instances between two distances. To support this, Distance now implements comparable based on the normalized value of it.
Tiny refactoring in TypeDiscoverer to avoid code duplication between the lookup of parameter type information for constructors and methods.
Added stream to the list of supported query method prefixes. Allow Stream to be used as return type for paginating queries, too.
Renamed Java8StreamUtils to StreamUtils. Some additional JavaDoc.
Original pull request: #116.
A CloseableIterator abstracts the underlying result with support for releasing the associated resources via close() which can be transparently be used with try-with-resources in Java 7 since Closeable implements AutoCloseable from Java 7 on upwards. Added detector methods to QueryMethod to check whether the current method returns a Stream.
Introduced ReflectionUtils.isJava8StreamType to safely detect whether the given type is assignable to a Java 8 Stream. Introduced CloseableIteratorDisposingRunnable that can be registered as a cleanup action on a Stream.

Extend AuditableBeanWrapper to allow access to the last modification date of a target object. Made AuditableBeanWrapperFactory an interface and renamed what’s been previously known under this name as DefaultAuditableBeanWrapperFactory.
The components previously relying on a MappingContext to lookup a PersistentEntity now use PersistentEntities to be able to back a collection of MappingContexts behind that and also avoid unmanaged types to be added to the MappingContext.
We now also register the JSR-310 and ThreeTen back-port converters with the ConversionService to be able to get and set auditing dates as these types.
We now ship a ProxyingHandlerMethodArgumentResolver that gets registered when @EnableSpringDataWebSupport is activated. It creates Map-based proxy instances for interfaces used as Spring MVC controller method parameters.
Made ObjectInstantiator interface public as otherwise the generated class to implement it cannot access it and thus the usage of the ByteCodeGeneratingEntityInstantiator fails completely.
PreferredConstructor.isEnclosingClassParameter(…) now eagerly returns if the parameter itself is not an enclosing one and thus avoids a collection lookup and equals check. Moved equals check for the type to the very end of the equals check to increase the chances that other inequality guards kick in earlier.
AbstractMappingContext now leaves the non-null-check for getPersistentEntity(…) to the factory method of ClassTypeInformation.
We now pre-calculate the hash codes for TypeInformation implementations as far as possible as the instances are used as cache keys quite a lot. The same applies to AbstractPersistentProperty.
BasicPersistentEntity now uses an ArrayList we sort during the verify() phase to mimic the previous behavior wich was implemented using a TreeSet as ArrayLists are way more performant when iterating over all elements which doWithProperties(…) is doing which is used quite a lot.
BeanWrapper now avoids the getter lookup if field access is used.
SimpleTypeHolder now uses a CopyOnWriteArrySet to leniently add types detected to be simple to the set of simple types to avoid ongoing checks against the inheritance hierarchy.
Introduced a map(Converter converter) method on Slice and Page to be able to easily transform the elements and create a new Slice or Page of the transformation result.
On Java 8 this allows code like this:
Page<String> strings = …;
Page<Integer> ints = strings.map(String::length);
In case the repository lookup for a given domain type fails we traverse the given types super-types and try to detect a repository for those.
Original pull request: #110.
Simplified implementation of Path conversion. Inlined helper domain types to not to pollute the packages with types that are only used within that very one test class.
Original pull request: #111.
Ported the projection infrastructure previously residing in Spring Data REST and extended it by defaulting to a Map-backed source to store and retrieve data.
Separated out the SpEL based functionality mostly for SOC-reasons and easier testability.
Related tickets: DATAREST-437, DATACMNS-618, DATACMNS-89.
Extended the implementation of DomainClassConverter to also support converting domain types into their identifier types and transitively convertible types.
Ported Spring Data REST's converters for Distance and Point and turned them into Formatter instances. Extended Metric interface to return an abbreviation. Added getUnit() to Distance and tweaked Jackson setup to ignore the additional property.
We now automatically register the news introduced Formatters when using @EnableSpringDataWebSupport so that Point and Distance values can be parsed and printed from and to Strings out of the box.
We now make the field detected by the callback accessible so that the value lookup doesn't fail for private fields. Added a few more unit tests to verify behavior.
PageImpl now makes sure that the total given to the constructor is never less than then number of items given to make sure we do not mask broken count calculation by creating an actually invalid instance.
Related ticket: DATAMONGO-1120.
To be able to verify the conversion of List based query execution results into Sets I extracted a QueryExecutionResultHandler that applies the already implemented handling for Optional types and eventually general prost processing in case the return type declared at the repository query method doesn't match the returned value.
Added additional unit tests for Optional handling.
RepositoryConfigurationExtensionSupport.registerBeansForRoot(…) now hands the extracted source of the configuration to the bean registration for the RepositoryInterfacePostProcessor.
The bean definitions that were registered for a repository configuration setup we registered once for every usage of the repository configuration element (annotation or XML). This caused multiple registrations of the very same bean definition which - as in case of the RepositoryInterfaceAwareBeanPostProcessor - apparently leads to performance problems in the container startup. Feedback for the latter claim is already asked for but we improved the registration setup nonetheless.
Introduced a registerIfNotAlreadyRegistered(…) method on RepositoryConfigurationExtensionSupport to allow easy registration of to-b-registered-once-and-only-once beans. We now hint towards the newly introduced method in registerWithSourceAndGeneratedBeanName(…).
Added key/value specific PersistenceExceptionTranslator and use it within KeyValueTemplate. Fixed some todos in JavaDoc and added missing tests. Renamed test class for SimpleKeyValueRepository according to the changed name.
Original pull request: #95.
Extracted KeySpaceUtils from KeyValueTemplate and pulled in the copy of MetaAnnotationUtils to hide it from the outside. Separated related test cases into dedicated test class.
Renamed BasicMappingContext to KeyValueMappingContext and BasicPersistentProperty to KeyValuePersistentProperty. Fixed spelling in SpelQueryCreatorUnitTests.
Moved MappingContext into separate package to satisfy architectural guidelines. Created dedicated KeyValueRepositoryNamespaceHandler to avoid a circular reference between commons and the key-value subsystem.
Made the query creator type an annotation on @EnableKeyValueRepositories so that it's not exposed to the user to be configured. Added the necessary ImportBeanDefinitionRegistrars to the Hazelcast and EhCache implementation. Removed @since tags from those modules at they're not going to make it into Spring Data Commons. Renamed EnableEhCacheRepsotoriesUnitTests to EnableEhCacheRepositoriesIntegrationTests as well as the same for the Hazelcast specific test.
The KeyValueRepositoryConfigurationExtension now explicitly registers a KeyValueMappingContext unless one is already registered. AnnotationRepositoryConfigurationSource now explicitly exposes an AnnotationMetadata instance for the annotation that triggered the configuration.
Turned SpelCriteriaAccessor and SpelPropertyComparator into classes to be able to pass them a SpelExpressionParser to be able to get rid of SpelExpressionFactory eventually. Made both classes as well as SpelQueryEngine package protected for now.
Moved repository implementations into support package. Updated architcture description JavaDoc polish, spacing, blank lines. Added TODOs.
Original pull request: #95.
Added basic infrastructure for repositories on top of key-value data stores. For more details see the original pull request.
Original pull request: #95.
PersistentEntity now exposes an getIdentifierAccessor(…)-method that allows obtaining the identifier of an entity without using a PersistentProperty instance. This allows advanced scenarios (like multi-property identifiers). Also we can use store specific means to optimize id lookups to e.g. avoid proxy initialization for lazy loading proxies.
