Added a test for loading of QuerydslPredicateArgumentResolver, but it fails presumably because EnableSpringDataWebSupport is not in effect.
Renamed SpringDataWebConfigurationUnitTests to SpringDataWebConfigurationIntegrationTests since it is actually an integration test.

ProxyingHandlerMethodArgumentResolver is now more lenient when it comes to which types to support for proxying. As indicated in the ticket, we've been to aggressive opting in for all interfaces which - depending on the order of converter registrations - caused us interfering with other interface based resolutions (e.g. in Spring Mobile, Security etc.).
We now only aggressively kick in if either the type or parameter is annotated with @ProjectedPayload or the type itself is not a Spring Framework or native Java one. This should leave user defined types still be accepted whereas the types we previously erroneously interfered with should now be ignored.
Entities without an identifier previously an exception because the IsNewStrategyFactory wasn't able to determine a strategy even if there was no auditing to be applied in the first place.
We now eagerly check for auditability and skip the lookup for an IsNewStrategy completely in case that check returns false.

Equipped @Persistent, @RepositoryDefinition and our Repository marker interface with @Indexed so that Spring 5's annotation processor will detect types annotated with or extending the aforementioned type for inclusion in the component index.

To make sure that event handlers can read the state of the aggregate persisted, we now invoke the call to the repository before publishing the events. That shouldn't make too much of a difference to most listeners as the event usually contains a reference to the aggregate. However, the new model generally aligns with the approach of reporting what *already has happened* better that our previous approach of first publishing the events and then invoking the repository method.

We now exclude getter methods that are default methods from the consideration which properties of a projection interface are considered input properties in the first place.
Some additional Java 8 polish in DefaultProjectionInformation.
We now manually filter already gathered property names in ReturnedInterface.getInputProperties() as we have to deal with duplications for properties with the same name at different levels of the inheritance hierarchy.
RepositoryFactoryBeanSupport now takes the repository interface as a constructor argument instead of as a setter. This makes sure that the container induced type prediction for factory beans actually wires the interface *before* it calls getObjectType() on the instance. This allows us to remove the extra infrastructure we had in place to predict the bean types and autowiring will just work out of the box.
Adapted infrastructure code accordingly, removed obsolete infrastructure code and adapted test cases accordingly.
The interceptor discovers whether a transaction was running before the call entered the repository proxy and exposes that fact via ….isSurroundingTransactionActive() for donwstream usage.

Javaslang's collection and map types can now be used on repository query methods and get adapted similarly to nullable wrapper types (like JDK's Optional). Also made TypeInformation infrastructure aware of the map type so that a value type lookup gets handle correctly.
We now support downcasts (e.g. user.as(QSpecialUser.class).…) expressions in Querydsl web binding. We do so by skipping the introduced intermediate step in the path when calculating the dot path.
Refactored the internals of the binding to now work based on a PathInformation implementation for which either a Querydsl Path or a Spring Data PropertyPath can be used. This allows us to reuse the paths of predefined bindings.
A bit of Lombok cleanup in internal implementations.
Previously a null value was added to the list of associations if it was handed to BasicaPersistentEntity.addAssociation(…). We now drop those null values and log a warning as it usually indicates a MappingContext implementation identifying a property as association but subsequently failing to look it up.
Both the configuration code looking up Spring Data specific Jackson modules as well as the code detecting whether we have multiple Spring Data modules on the classpath used component scanning. That can have quite significant impact on startup times.
This commit replaces the classpath scanning with the use of SpringFactoriesLoader that now requires modules that want to extend the behavior of Spring Data's web configuration or indicate a repository implementation being present by shipping a file called META-INF/spring.factories. Spring Data relies on the following keys:
- org.springframework.data.web.config.SpringDataJacksonModules - list the Spring configuration classes that will expose additional Jackson modules that are supposed to be registered for Spring Data's Jackson web support
- org.springframework.data.repository.core.support.RepositoryFactorySupport - list the Spring Data repository factory implementation class that implements repository support for your module. The general detection and configuration mechanism for user repositories is not affected by this. Currently Spring Data only uses the pure number of different entries for that key to switch into strict configuration mode in case we find more than one entry.
We now publish events for all methods named "save" on the repository. Fundamentally, that's in place to capture calls to CrudRepository.save(Iterable entities), too.
Some minor refactorings to the internal setup of EventPublishingMethodInterceptor. More JavaDoc.
Introduced @DomainEvents usable on a method of an aggregate root. The method will be invoked when the aggregate is passed to a repository to save and its returned value or values will be exposed via an ApplicationEventListener.
Also, the aggregate can expose a method annotated with @AfterDomainEventPublication which will be invoked once all events have been published.
We now try to look up a target class method based on concrete name and parameter type before falling back on the more expensive type matches. This also eliminates the possibility of invalid method matches as described in the ticket.
We now no longer attempt query creation for static methods declared on a repository interface. This allows static method usage inside of repository interfaces.
interface PersonRepository extends CrudRepository<Person, String> {
static String createId() {
// …
}
default Person findPerson() {
return findOne(createId());
}
}
The Descriptor class is nested in the ReactiveAdapter interface which in turn has a strong dependency to Project Reactor as it exposes some if its types as method return types. That means we can't refer to Spring's Descriptor without Project Reactor on the classpath.
Introduced a custom Descriptor that exposes the setup needs we have using a fluent API.
We now also only conditionally actually the ReactiveAdapterRegistry as eagerly instantiating it in RectiveWrapperConverter causes a strong dependency on Reactor.

Reactive type conversion now happens fully inside of ReactiveWrapperConverters and does not require an external ConversionService. This change allows changes to reactive type conversion without changing the API since all details are encapsulated by ReactiveWrapperConverters.
Introduced ReactiveRepositoryFactorySupport so that validation for the presence of all required converters (e.g. RxJava 1) does not have to be repeated in individual stores.
RepositoryConfigurationExtensionSupport now exposes a ….useRepositoryConfiguration(RepositoryMetadata) so that extensions can opt in or out of an interface taking part in configuration more easily. Turned loadRepositoryInterface(…) private again as extensions should be able to just inspect the RepositoryMetadata now.
Some parameter rename in ReactiveWrapperConverters to avoid confusion.
RepositoryMetadata now exposes an ….isReactiveRepository() that's implemented by inspecting the backing repository interface for any reactive wrapper type appearing in method signatures. That allows us to move down the use of a ConversionService down to ReactiveRepositoryInformation.WrapperConversionMatch.
Made a couple of methods static that could be. Simplified some logic using streams. A bit better wording in assertions. Some formatting when using streams.
Move reactive wrapper conversion to ReactiveWrapperConverters to minimize touching points with reactive APIs. ReactiveWrapperConverters is used only from reactive repository components and does not initialize with blocking API use. This removes the need of having Project Reactor on the class path for non-reactive use.
- Rename RxJava...Repository to RxJava1...Repository
- Use Completable and Observable instead of Single for results without values/optional values
- Remove reactive paging for now as it does not really fit reactive data streaming
- Expose ReactiveWrappers.isAvailable(ReactiveLibrary) method to query library availability
We now expose reactive interfaces to facilitate reactive repository support in store-specific modules. Spring Data modules are free to implement their reactive support using either RxJava 1 or Project Reactor (Reactive Streams). We expose a set of base interfaces:
* `ReactiveCrudRepository`
* `ReactiveSortingRepository`
* `RxJava1CrudRepository`
* `RxJava1SortingRepository`
Reactive repositories provide a similar feature coverage to blocking repositories. Reactive paging support is limited to a `Mono<Page>`/`Single<Page>`. Data is fetched in a deferred way to provide a paging experience similar to blocking paging.
A store module can choose either Project Reactor or RxJava 1 to implement reactive repository support. Project Reactor and RxJava types are converted in both directions allowing repositories to be composed of Project Reactor and RxJava 1 query methods. Reactive wrapper type conversion handles wrapper type conversion at repository level. Query/implementation method selection uses multi-pass candidate selection to invoke the most appropriate method (exact arguments, convertible wrappers, assignable arguments).
We also provide ReactiveWrappers to expose metadata about reactive types and their value multiplicity.
PageableHandlerMethodArgumentResolver.isFallbackPageable() now correctly guards against the fallback Pageable being null, a situation that's explicitly deemed valid in setFallbackPageable(…).
