Introduced dedicated callback interfaces to customize the HandlerMethodArgumentResolver instances registered by SpringDataWebConfiguration. This allows bean definition registration of those customizer interfaces instead of having to extend a configuration class.

Previously we explicitly intercepted repository methods named save(…) and saveAll(…) which unfortunately results in custom variants of that (e.g. JpaRepository's saveAndFlush(…)) not causing event publication.
We now publish events for methods whose names start with save….
Introduced ConverterBuilder which exposes API to register Spring GenericConverters for the use with a store module's CustomConversions. This allows simple registration of such converters using Java 8 lambdas.
ConverterAware converters = ConverterBuilder.reading(String.class, Long.class,
it -> Long.valueOf(it)).andWriting(it -> Object::toString);
The setup can also be done from the reading side which would just need the method invocations inverted. The resulting ConverterAware will expose the registered converters so that they can be easily handed to a CustomConversions instance. Partial creation of either reading or writing converters is possible, too with the returned instance then only exposing one of the two converters.
CustomConversions now considers ConverterAware and treats them appropriately for ConvertiblePair registration as well as during the registration in the ConversionService. Tweaked parameter types in CustomConversions to rather accept a Collection<?> for the converters (previously List<?>). Also, registerConverterIn(…) now takes a ConverterRegistry over a GenericConversionService. Polished Javadoc and non-null assertions.

In case a repository method execution returns a JDK 8 Optional in the first place, the Optional instance had been wrapped into a third-party null-wrapper as is. We're now unwrapping the value held inside that optional and forward it to the value conversion.
We now follow a more consistent naming scheme for the methods in repository that are driven by the following guidelines:
* Methods referring to an identifier now all end on …ById(…).
* Methods taking or returning a collection are named …All(…)
That results in the following renames:
* findOne(…) -> findById(…)
* save(Iterable) -> saveAll(Iterable)
* findAll(Iterable<ID>) -> findAllById(…)
* delete(ID) -> deleteById(ID)
* delete(Iterable<T>) -> deleteAll(Iterable<T>)
* exists() -> existsById(…)
As a side-effect of that, we can now drop the Serializable requirement for identifiers.
Updated CRUD method detection to use the new naming scheme and moved the code to Java 8 streams and Optional. Adapted RepositoryInvoker API to reflect method name changes as well.
We now support Order creation with Order.asc(String) and Order.desc(String) factory methods as shortcut to constructor creation via new Order(Direction, String).
Sort.by(Order.asc("age"), Order.desc("name"));
Deprecated Order(String) constructor in favor of the Order.by(String) factory method. Replace references to new Order(String) with Order.by(String).

Used @RequiredArgsConstructor in a couple of places in favour of manually declared constructors. Removed obsolete factory methods on Range. Adapted test cases accordingly.
Original pull request: #212.
We now encapsulate a boundary in Range within a Bound value object. Bound consists of a value and whether the value is inclusive or exclusive. Boundaries without a value are unbounded. We introduced factory methods for Range and Boundary creation using primitives and a builder to build a Range.
Range<Long> range = Range.unbounded();
Range<Integer> range = Range.from(Bound.inclusive(10)).to(Bound.inclusive(20));
Range<Integer> range = Range.of(Bound.inclusive(10), Bound.inclusive(20));

Extracted CustomConversions — whose code has largely been duplicated between the MongoDB, Couchbase and Cassandra modules — into Spring Data Commons. Store-specific extensions can now be contributed via a StoreConversions value type that carries both, store-specific default converters as well as a store-specific SimpleTypeHolder to augment the default list of simple types.
Removed SimpleTypeHolders public default constructor in favour of a protected one and a static DEFAULT instance for plain references.
Original pull request: #210.
We now hand the Pageable contained in the Page to the code that constructs the self link.
Added toEmptyResource(Page, Class) to force clients to resolve an optional base link before calling the method. Removed deprecated method to append pagination template parameters.
We now expose the Pageable that was used to create a Slice via its API. Slice itself constructs a default PageRequest so that current implementations of it still work as before.
Removed custom JUnit integration as we can just create HidingClassLoader instances in the test and the integration actually causes more code being needed (additional JUnit rule, method level annotations etc.).
Tweaked ShadowingClassLoader to make obvious what has been changed over the Spring Framework variant. Created upstream ticket [0] to ask for the tweaks that would allow us to remove the class again.
Changed SpringDataWebConfigurationImportSelector to be lenient against the ResourceLoader not being available.

ClassLoaderRule with @ClassLoaderConfiguration allows easy creation FilteringClassLoader. Changed usage pattern of ClassUtils.isPresent(…) in order to ease testing. Copied the ShadowingClassloader from SpringFramework to get a constructor that doesn't shadow anything by default.

The switch to Java 8 and thus to Collectors.toMap(…) to assemble the root object's methods as functions broke due to the fact that overloaded methods have the same name which causes a collision in keys when preparing the map of functions.
We now use the same approach as before, of letting later methods trump earlier ones as this fixes the original bug. Filed DATACMNS-1026 to keep track of that problem.

Improve JavaDoc. Remove findAll declarations in reactive sorting repositories as they are inherited with the same signature.

Provide RxJava 2 Repository interfaces using back-pressure enabled Flowable as default return type for multi-element queries and Maybe for queries that can complete without emitting a value.
Original Pull Request: #194
We now attempt to look up a target class method based on exact name and parameter types before falling back on the more expensive type matches. This also eliminates the possibility of invalid method matches as described in the ticket.

RevisionRepository now returns Optional for methods that could previously return null. Revision exposes additional methods to lookup required revision numbers and dates. Revisions now implements Streamable and exposes a ….none() factory method to create an empty instance.
AnnotationBasedRevisionMetadata now uses Lazy to lookup the fields with revision annotations. AnnotationDetectionFieldCallback now also uses Optional in places it previously returned null. StreamUtils now exposes factory methods for Collector instances producing unmodifiable List and Set instances.
Related ticket: DATACMNS-867.
The refactoring for DATACMNS-867 has dropped support to customize the repository factory bean class on both the @Enable-annotations and the XML namespace. Reintroduced this feature, added a test case and moved the fallback into the value that's defined by the configuration extension inside DefaultRepositoryConfiguration.
The new method allows to look up identifiers and immediately fail in the case of absence. Introduced the method as default method but also a new base type TargetAwareIdentifierAccessor to throw an exception with more context, i.e. the actual target bean we try to look up the identifier on.
