ResourceProcessor supports Streams now and adds a map(…) step to apply projections.
Also, the ProjectingConverter falls back to use a default ConversionService instance to make use of the object mapping functionality implemented in ObjectToObjectConverter, i.e. the ability to just map an object returned from the store to a DTO in case that latter exposes a constructor or factory methods taking the source instance as parameter.

Add additional check for detecting customized method where method contains generics. Overriding methods without generics already works, this patch simply makes the behavior consistent.

The translation of the list of actual type parameters into an array now uses the loop index correctly. Previously, it always used the first type parameter.
Added proper equals(…) and hashCode() methods to SyntheticParameterizedType to make sure instances created for the same type information and type parameters are considered equal.
Simplified test case. Formatting in ClassGeneratingPropertyAccessorFactory.

Removed DefaultPersistentPropertyAccessorFactory as it only delegates to the class generating one. Tweaked AbstractMappingContext to actually use the latter in the first place. Introduced BeanWrapperPropertyAccessorFactory to implement the default behavior of using a BeanWrapper and initialize BasicPersistentEntity to avoid a null clause in getPersistentPropertyAccessor(…).
Removed getPersistentPropertyAccessorFactory and rather rely on ReflectionTestUtils in tests to avoid additional API being exposed.

PersistentPropertyAccessorFactory can be set on a BasicPersistentEntity. This is done by AbstractMappingContext once the entity is verified. This change reduces the count of PersistentPropertyAccessorFactory instances and performs the isSupported check only once, when initializing the entity.

Made as many methods in ClassGeneratingPropertyAccessorFactory static as possible. Some code formatting. Some warning suppressions where needed.

We now support generated PersistentPropertyAccessors when using Java 7 and if property/association name hashCodes are unique within a PersistentEntity.
Generated PersistentPropertyAccessors provide optimized access to properties. They use either MethodHandles or direct property/field access, depending on the visibility/final modifiers of the entity type and its members. A generated PersistentPropertyAccessor is injected into the originating class loader of the entity class to enable optimizations for package-default/protected member access.

We now completely ignore all core Java types (i.e. types with a package name starting with "java.") from being DTOs. This allows query methods to project on date time types, too.
The indicator of whether custom construction is needed for a class based return type now includes whether input properties are available in the first place.
In case a DTO type exposes multiple no-argument constructors we now leniently abort the parameter name detection and let downstream users decide what to do in this particular case.
The problematic case can't be outright rejected here already as there's valid scenarios for that, e.g. in JPA the type could be used for multiple query methods, using explict constructor expressions listing arguments explicitly and thereby select one of the multiple constructors.
Renamed ExampleSpecification to ExampleMatcher and introduced a matching() factory method, dropping the dedicated override mechanism for types for now. Updated documentation accordingly.
Used Lombok for constructor creation, field defaults, toString() as well as equals(…) and hashCode() implementations.
Tweaked imports in unit tests. Renamed methods to express expected behavior.

Split Example and ExampleSpec to create reusable components. Refactor builder pattern to a fluent API that creates immutable instances. Split user and framework API, Example and ExampleSpec are user API, created ExampleSpecAccessor for modules to access example spec configuration. Create static methods in GenericPropertyMatchers to ease creation of matchers in a readable style. Convert PropertySpecifier to inner class and move PropertySpecifiers to ExampleSpec.

Added required types for Query by Example which should be used by the individual store implementations.
Generally the Example type captures a sample object and allow various settings concerning the mapping into an actual query. So there’s configuration options for handling null values, string matching, property paths to ignore,

ResultProcessor.processResult(…) now explicitly handles null values to prevent IllegalArgumentExceptions being provoked in the ProjectionFactory which occurred if null values were handed down to it.
We now resolve composed annotation values using @AliasFor within AnnotationBasedPersistentProperty and BasicPersistentEntity. Nevertheless it is up to the individual store implementation to make use of this.

Previously, we registered an InstantiationAwareBeanPostProcessor to predict the type to be created by RepositoryFactoryBeanSupport by inspecting a particular property value of the registered BeanDefinition.
This has now been elevated to a more generic mechanism that can get a FactoryBean type configured with a set of properties to inspect for a configured type. That new infrastructure now replaces the explicit configuration for RepositoryFactoryBeanSupport with one that's set up via configuration.
Fixed indentation to use tabs instead of spaces. Tweaked structure of if-clauses in PropertyAccessingMethodInterceptor to reduce nesting. Made helper method static.
Restructured test cases slightly and used ExpectedException rule to verify exceptions. Moved newly introduced test methods more to the end of the file (new tests last).
Added author and copyright year extensions where necessary.

Introduced a template method to override the creation of a PagedResource to allow subclasses to create a more concrete instance than PagedResource itself.
The ChainingConverter now returns values as soon as one converter in the chain produces an instance that's compatible to the target type. This allows ResourceProcessor clients to provide a Converter to take care of the complete conversion themselves.
QueryMethods now expose a ResourceProcessor which is exposes information about the final to be created object types which can either be DTOs containing a persistence constructor (see @PersistenceConstructor) or projection interfaces. The former are analyzed for constructor properties so that store implementations can use that information to create projected queries that return exactly the fields required for that DTO.
Projection interfaces are inspected, their properties are considered input properties and the same projection queries can be issued against the data store. If a projection contains dynamically calculated properties (i.e. it uses SpEL expressions via @Value) the original entities have to be queried and can be projected during post processing.
ProjectionFactory now exposes a more advanced ProjectionInformation that has additional meta information about the projection type. ProxyProjectionFactory now refers to the BeanClassLoader instead of the ResourceLoader.
RepositoryFactory(Bean)Support now also implement BeanFactoryAware to forward the BeanFactory to the SpelAwareProxyProjectionFactory which in turn now gets handed into the QueryLookupStrategy as well as the QueryMethod.
Parameter now knows about a dynamic projection type, which is a query method parameter of type Class bound to a generic method parameter and will be used to determine the projection to be used on a per call basis.

If a single path is now handed to QuerydslBindings.bind(…), a specialized AliasingPathBinder is returned which allows defining an alias the binding will be exposed under.
By default that alias will cause the original binding being black-listed and thus become unavailable for binding. This can be overridden by explicitly white-listing the properties to be bindable.
Switched to new Querydsl 4 artifacts and adapted to changed package names and API changes.
Cleaned up some JavaDoc and APIs in QuerydslBindingsFactory and QuerydslBinderCustomizer.
If the type lookup from the store source returns a raw generic type (e.g. resolving the value of a generic property against a value of that generic type - i.e. not a more concrete type binding the generic information) in the context of a generic property, we previously did not apply the generics information of the contextual instance to that very raw type.
We now expose a TypeInformation.specialize(ClassTypeInformation) which applies the current generics context to the given raw type and basically creates a synthetic parameterized TypeInformation instance.
DefaultTypeMapper applies this specialization by default now with ClassTypeInformation simply returning the given type as is so that we don't create any resolution overhead in case no generics are involved in the first place.
The ProjectingMethodInterceptor now uses a default ConversionService instance to try to convert a potentially not matching result of the target invocation into the type the projection requires before the attempt to create nested projection.
Query method parameter values of JDK 8 or Guava Optional type are now transparently unwrapped on parameter value access. ParametersParameterAccessor now unwraps them on instance creation.
The assignability check of method return types now explicitly detects wrapper types supported in QueryExceutionConverters and automatically unwraps those before the actual check.
We now correctly inspect the sort parameter values and also fall back to the default if a single, empty parameter value is given.

Added hint to which constructor of the superclass to override. Added test cas e to make sure the expected types are advertised in the case of an error.
