We now explicitly set a base backage in the Neo4jConfiguration to make sure, the domain classes get added to the MappingContext upfront. Filed DATAGRAPH-448 [0] for some reasonable defaulting going forward.

Introduced BackendIdConverter SPI to be able to register custom components that will be used during URI construction and URI parsing to determine the actual backend identifier.
To register a custom BackendIdConverter simply declare a bean definition for it in the ApplicationContext. The Spring Data REST URI creation infrastructure (RepositoryEntityLinks in particular) will pick it up transparently.
The JIRA issue asserts that PUT wasn't properly storing things. But now it does. A partial record causes all other fields to get nulled out. Added a test case to confirm this.
Original pull request: #134.
PropertyAccessingMethodInterceptor now ignores Object methods and forwards them to the proxy target. ProxyProjectionFactory now correctly sets up the SpEL root object for reference in expression on accessors.
Previously we only handled URIs to associations on the root object level as the mapping information for potentially nested embeddables were not accessible via the Repositories instance. This is now fixed by switching to the newly introduced PersistentEntities.

We now register a RepositoryRelProvider that hadn't been exported before so that clients using a RelProvider will automatically see potentially customized rels for repositories.
Changed RepositoryRelProvider to lazily depend on the ResourceMappings as will be requested eagerly for injection into the configuration class itself.
Prevent NullPointerException in case we don't find a requested projection. We simply return the source object if so. Added unit tests to make sure we don't introduce a regression.
Removed NoOpProjector from production code as it is only needed in test cases anyway.
This commit introduces support to access resources via projections, which means naming a dedicated set of properties of the entity to be exposed and being able to refer to that set through a request parameter.
## General usage
Projections are defined as interfaces that mimic the properties of the domain class to be exported:
@Projection(types = Customer.class, name = "summary")
interface Summary {
String getFirstname();
String getLastname();
AddressSummary getAddress();
}
interface AddressSummary() {
String getZipCode();
}
The projection interface can be annotated with @Projection to be auto-discovered. We scan all packages in which we find domain types to be exported for projection types and auto-register them. For manual registration, use RepositoryRestConfiguration.projectionDefinitionConfiguration().addProjection(…) and manually register them.
If a projection is registered for a given type, this will be indicated via a "projection" template variable in the URI pointing to resources with projections. The name of the variable can also be configured on ProjectionDefinitionConfiguration.
## Internals
The projection interfaces are consider bean property delegates by default. This means, that for the above interfaces we will lookup the firstname, lastname and address property of the projection target. In the case of address we re-project the result of the proxy target invocation with a sub-projection onto AddressSummary.
For more advanced use-cases you can annotate a method of the projection interface with @Value and use a SpEL expression to invoke further functionality and return that to be rendered:
interface MyProjection {
@Value("#{@myBean.someMethod(target)}")
SubProjection getValue();
}
This projection would call the someMethod(…) method on a Spring bean named myBean handing the proxy target to the method. The result will be projected in turn onto a type called SubProjection.
As the projection objects are exposed to Jackson as is, they can be annotated with Jackson annotations to further customize the representation.
AssociationOmittingSerializerModifier not correctly handles transient properties, which means it's handling null PersistentProperties correctly.
Also, AbstractRepositoryRestController.handleNotReadable(…) is not bound to HttpMessageNotWritableException anymore which caused the former errors to be masked by a Spring MVC exception claiming about the exception handler method not being invokable correctly.
Refactored PersistentEntityJackson2Module to move a lot of the customization logic into Bean(De)SerializerModifiers. Those allow to modify the Jackson metadata for a given type programmatically so that we can register the appropriate (de)serializers for associations.
On the serializing side of things this allows us to easily turn associations into links and simply delegate to object serialization as the delegation will simply ignore the association properties as they have been dropped using the modifier. This solves the advanced requirements of DATAREST-117 nicely as all non-association properties are serialized using standard Jackson means so that all customizations apply.
On the deserialization side, we now support URIs as values for association properties to be able to submit references for non-optional associations on creation.
Related issue: DATAREST-117.
Simplified annotation detection. Added ignore guards to the association handling as well, so that associations not pointing to a repository managed resource can be ignored from being rendered as well.

Wrote test cases to verify it handles class level and attribute level annotations to ignore properties when rendering PersistentEntityResources.

Code polishing in DomainObjectMerger and related test cases. Fixed the related test cases. Cleanups in ControllerUtils to remove unneeded constants and make sure we really render no content for empty responses.
Refactorings in controller classes to reduce code duplication. We now do not allow POST requests for partial updates to property reference resources anymore but require the usage of PATCH.
Tweaked test helper methods to correctly implement basic interaction patterns.

Refactored the way the general support for an HTTP method for the resource exported. The decision is implemented in RootResourceInformation (formerly RepositoryRestRequest). Removed request specific information from that class and introduced a HandlerMethodArgumentResolver to be able to inject HttpMethod instance into controller methods (filed https://jira.springsource.org/browse/SPR-11425 to get that support into Spring Framework itself).
Generally moved away from throwing NoSuchMethodExceptions and correctly expose HttpRequestMethodNotSupportedException instead to make sure Spring MVC renders the appropriate allowed methods if possible.
Removed RepositoryInvokerHandlerMethodArgumentResolver as a RepositoryInvoker can be obtained from the RootResourceInformation where necessary.

Links are a read-only and basically have to be ignored during any inputs. This required removing the deserializer from PersistentEntityJackson2Module. This will cause the object mapping to fail as it doesn't know about the links property in the request body. Instead of requiring that every entity apply the necessary annotation, the mapper is configured to not fail on non-existent attributes. This allowed all the tests to pass while properly handling PUT operations.

CrudRepositoryInvoker now detects re-declared CRUD methods and falls back to reflection invocation if the re-declaration is detected.
Inspired by PR #126 by Nick Weedon but avoiding the introduction of a dependency to Spring Security by using a more precise testing approach.

ValidatingRepositoryEntityListener previous referred to a Repositories instance which causes a circular reference on initialization after some changes in Spring Data Commons Repositories.
Major cleanups in the ValidatingRepositoryEntityListener implementation.
Properties with null values properly get rendered in JSON outputs. This was fixed some time ago. Added test case to prove it.
Original pull request: #132.
Upgraded to Spring Data RC modules, Spring HATEOAS 0.9.0.RELEASE and Spring Plugin 1.0.0.RELEASE. Removed placeholder for Jackson 2 version as it's in the parent build pom now. Switched to milestone repository.
Generally polished implementation and test cases for Greg's contribution.
Re-ordered parameters in ControllerUtils' helper methods for consistency.
Use Spring's CollectionFactory to create a suitable collection for the handled properties in the first place to avoid unnecessary conversion later on.
Removed duplication in test cases. Polished JavaDoc in UriListHttpMessageConverter and moved to a Scanner based implementation to read the request body.
Adapted to latest changes in Spring HATEOAS. Reactivated ResourceStringUtilsTests.

This PR is inspired by #86, but had to be written from scratch because it was over 10 months old when this was undertaken. It was unmergeable.
Essentially, by casting existing collections and then iterating over them and making adjustments should render more efficient back end database operations. Only for a PUT should a new collection be created.
This PR not only updates these operations, but provides test cases to back up these edits, i.e. a test case for POSTing to a collection, PUTing to a collection, and DELETE-ing from a collection.
Adds ability to return an empty response with only the Location header populated by looking at the property update's incoming URL.

@RepositoryRestResource exposes more detailed attributes tailored to the use case of exposing a repository. @RestResource is still recognized on repository interfaces but we now issue a warning and indicate the new annotation to be used.
Introduced a minimal ResourceDescription interface and let @Description be used within @RestResource and @RepositoryRestResource. We now generate default resource bundle keys and resolve them against a "rest-messages" resource bundle by default. JsonSchema converter now uses the rendered descriptions for schema descriptions.
If the resource exposed for a domain or repository type is considered a paging resource we now return a templated URI. Introduced ResourceMapping.isPagingResource() to allow clients to find out about whether the resource is actually capable of pagination. Adapted implementations to inspect the findAll(…) method as well as the search methods for a Pageable parameter.
Tweaked pom.xml to create correct classpaths if the IDE uses direct workspace project references.
MethodResourceMapping now exposes the parameters a query method expects. The RepositorySearchController the uses these to append the
Upgraded to Spring Data Commons 1.7.0.BUILD-SNAPSHOT.
