We now use a non-static cache for TypeInformation instances in SimpleTypeInformationMapper to make sure Spring Boot's development tools can correctly reload classes. Removed the static singleton instance of SimpleTypeInformationMapper in favor instantiating it directly.
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.
Linked back to the release train names from the section on dependency management with Boot for clarity. Added additional line break to avoid the first line in the repositories.adoc being interpreted as text.
Added sections to the reference documentation to elaborate on the newly introduced web integration for Querydsl.
Added documentation for Future<T> return types.
Corrected the closing tag for dependency for Spring Data Commons section on dependencies. Fix broken links to Spring Framework reference documentation. Update build requirements in readme.
Original Pull Request: #137
If standard Querydsl StringPaths are used without any reference to a query class tree, we previously dropped the first segment of the path expression.
Moved to a completely different algorithm to determine the path by just using the Path's toString() representation and the root removed if necessary.
If a keyword was contained in a complex property path (like In in SomeInfo), the property path was invalidly cut of in the middle. We now simply use the length of the keyword to extract the actual property from the candidate. This should be faster anyway as it doesn't require another lookup of the pattern in the source candidate.

The JavaDoc of PersistentPropertyAccessor now explicitly hints to PersistentEntity.getPropertyAccessor(…) to make obvious how instances of it can be obtained.
Moved all Querydsl related bean definitions and customizations to a dedicated configuration class that only gets included if Querydsl is on the classpath.
Extracted a QuerydslActivator for use in Spring Data REST, which uses HateoasAwareSpringDataWebConfiguration via inheritance, not via @EnableSpringDataWebSupport.
Previously, we exposed a QuerydslBindingsFactory as bean method return type which breaks Spring bootstrap even if it's lazy due to its references to Querydsl types.

QuerydslBindingsFactory creates a completely build up and customized QuerydslBindings instance for a given QuerydslBinderCustomizer type and domain type.
This basically involves creating or obtaining an instance of the customizer with the following algorithm:
1. If an explicit customizer type is given and no BeanFactory is configured, we'll simply instantiate the configured type. This allows simple customizer implementations with a no-arg constructor.
2. If a BeanFactory is configured and a customizer type configured, we're trying to locate a bean of that type in the BeanFactory, falling back to creating an instance of the customizer through the BeanFactory if no existing bean definition can be found. This allows unique customizer bean definitions or complex prototype scoped customizer beans created on the fly.
3. If no customizer type is configured, we check whether the the repository of the domain type implements QuerydslBinderCustomizer and use it if so.
The extraction of that functionality allows that algorithm being used by Spring Data REST, although only step 3 is currently used there as no explicit customizer can currently be configured with Spring Data REST.
