The exception messages used in the PersistentProperty.getRequired(Getter|Setter|Wither|Field)(…) now mention the name of the property that's offending.
ProxyProjectionFactory and ResultProcessor require a DefaultConversionService to convert values for projection proxies and to post-process query method results. Creating instances of these types requires an instance of the conversion service which previously created a DefaultConversionService instance (along all converter registrations) upon ProxyProjection/ResultProcessor instantiation.
We now use the shared instance that is initialized once and shared across all ProxyProjection/ResultProcessor instances to reduce garbage and improve the CPU profile.
This is needed for downstream projects that attempt to merge persistent entity instances and previously didn't have a chance to detect that an object had to be set as-is instead of being merged recursively.
PersistentPropertyAccessor is now generic to be able to retain the type information about the object it was created for and the return type of ….getBean(). Adapted client APIs.
As setting a PersistentProperty can actually change the object that the property is changed on, we now recursively traverse property paths up as longs as the setting of the property results in the bean not being replaced.
We've changed the APIs in the auditing subsystem so that we support immutable entities, mostly through MappingAuditableBeanWrapperFactory that uses a PersistentPropertyAccessor.
Add missing since tags. Extract methods to maintain single abstraction level per method. Move visitDefaultValue from ClassGeneratingPropertyAccessorFactory to BytecodeUtil. Extend Javadoc.
We now support updating of immutable Kotlin data objects by creating new copies through Kotlin's copy method that is generated along with data classes and immutable properties.
data class DataClassKt(val id: String) {
}
data class ExtendedDataClassKt(val id: String, val name: String) {
}
We now detect withher methods (withId(…)) that create a new object instance that contains the new property value. We support those wither methods to create new object instances from property updates. Classes following a wither pattern declare a withXXX(…) method that accepts the property value and return a new, instance of its own type associated with the property value. Along with this change we removed the ability to update final fields that worked by accident using reflection.
class ValueClass {
@Wither String id;
}
class ValueClass {
final String id;
ValueClass withId(String id) {
return new ValueClass(id);
}
}
We now calculate the number of expected default masks to filter synthetic constructors that do not match the expected parameter count. A Kotlin constructor with argument defaulting generates a synthetic integer argument for every 32 constructor arguments. This is independent of the number of actual optional arguments.
Previously, we used an non-exact check to consider constructors as default ones if they had at least two additional arguments. This caused the wrong constructor being used if the non-synthetic types matched the types of the default constructor.
Removed the explicit registration for JodaTime and ThreeTenBP to JSR-310 converters (originally introduced to support the unifying lookup of the last modified date in the auditing subsystem) as reading converters. This avoids the warning reporting that the source types (JodaTime and ThreeTenBP LocalDateTime) not being store-native types (which usually indicates a superfluous converter registration).
Updated the test cases to make sure these warnings aren't trigger due to test setups causing the same issue.
Moved test cases into PropertyPathUnit test so that they're closer to the implementation. Switched to Introspector.decapitalize(…) to follow the Java Beans Specification regarding the handling of all-uppercase properties.

PersistentEntity now exposes an ….isNew(…) method that exposes the same detection algorithm previously exposed through MappingContextIsNewStrategyFactory (Persistable in favor of the version property in favor of an identifier lookup). MappingContextIsNewStrategyFactory has been refactored to return an ad-hoc strategy to delegate to the newly introduced method.
The core message to implementing modules is that they should now prefer PersistentEntityInformation within their RepositoryFactorySupport implementation and move all customizations made in the store-specific EntityInformation implementation in PersistentEntity.
We now support the use of Vavr's Try as repository method return type so that exceptions caused by the repository method execution are wrapped into a Failure. Introduced a return type specific indirection of the execution. We now also recursively handle wrapper types so that Try<Option<…>> is valid, too.
Added support for Javaslang's Try, too.
We now expose what type or PersistentEntity an association points to by trying to match the association's type to identifier types to entities. In case multiple matches are found, we require the user to explicitly declare the target type via @Reference.
Introduced PersistentEntities.of(…) for convenience.
Introduced ProxyUtils.getUserClass(…) that by default is basically a facade for Spring's ClassUtils.getUserClass(…) but allows the registration of ProxyDetector implementations via Spring's SpringFactoriesLoader mechanism.
Moved all existing usages of ClassUtils.getUserClass(…) to ProxyUtils.
Moved newly introduced types into the ….data.repository.query package as the parser one contains types that parses queries from method names. Simplified the API surface by hiding SpelExtractor completely and making the API on SpelQueryContext more convenient to directly create a SpelEvaluator.
The goal is to extract the parts of query parsing that are generic into commons in order to avoid slightly different behavior in modules.
Extracted the QuotationMap from Spring Data JPA as well as the part of the parser that deals with extracting SpEL expressions.
Added the SpelEvaluator for evaluating the SpEL expressions.
Added enough configurability to satisfy the needs of Neo4j and JPA.
Mainly to support the different formats for bind parameter :name vs {name}.
We now have a refined replica of the EvaluationContextProvider API and SPIs in the org.springframework.data.spel package. It has seen a bit of a Java 8 overhaul by removing the SPI support class in favor of turning most methods in EvaluationContextExtension into default ones.
The already existing API has been renamed to QueryMethodEvaluationContextProvider to indicate it's working with additional semantics specific to query methods (i.e. the Parameters metadata). The internals have been refactored to use the new API but still detect implementations of the old EvaluationContextExtension interface. The implementations get wrapped into an adapting proxy to satisfy the new API so that the actual inspection and usage of the extension is now already done using the new APIs.
The repository configuration has slightly change so that the creation of the EvaluationContextProvider is now taking place within RepositoryFactoryBeanSupport's implementation of BeanFactoryAware.
AbstractMappingContext is now ApplicationContextAware and holds an ExtensionAwareEvaluationContextProvider using the configured ApplicationContext. That EvaluationContextProvider is forwarded to all MutablePersistentEntity instances. BasicPersistentEntity now exposes getEvaluationContext(…) to subclasses to easily create an EvaluationContext using the extension aware infrastructure.
Removed DefaultEvaluationContextProvider in favor of a simple constant in QueryMethodEvaluationContextProvider.

I added a cover page for the epub output, now that the Spring data reference guides will have epub output (through a commit against spring-data-build).

We now explicitly disable entity expansion in the DocumentBuilderFactory used by XMLBeam.
Introduced constructor in XmlBeamHttpMessageConverter to allow dedicated configuration of an XBProjector instance in case the defaults need tweaking and augmented the web configuration setup to automatically pick up a custom XmlBeamHttpMessageConverter bean instead of our own default if present.
After considering JSR-310 types to be simple we map these types primarily to java.util.Date as the majority of stores does not natively support JSR-310 types. Converters referencing JSR-310 types are now properly annotated with Reading/WritingConverter annotations to distinguish between reading and writing intents.
Othwerise, converters between JSR-310/java.util types and Joda/ThreeTenBackport to JSR-310 types interfere with conversion as regular java.util.Date types would convert to e.g. LocalDateTime.
We now consider all types in the java.time package as simple types to prevent deep reflective access. We are already excluding java.lang types for the same reason.

Previously a custom Iterable implementation would've caused QueryMethod.isCollectionQuery() to return true. We now solely rely on TypeInformation.isCollectionLike() (which checks for exact Iterable, Collection assignability and arrays) after handling potential wrapper types.
Instead of a simple check for assignability from Iterable, we now properly use TypeInformation.isCollectionLike(), which checks for Iterable equality or assignability of collections or arrays as well as an explicit check for Slice as that is needed to properly unwrap Page instances and Slices themselves. That prevents custom domain types implementing Iterable from being unwrapped into their element types.
