In case @RestResource was used to customize the path a method resource was mapped to, we didn't correctly fall back to the method name as rel in case no rel was configured explicitly.
We now check for a rel being configured and fall back to the method name if we don't discover manual configuration.
RepositorRestConfiguration now has a ….useHalAsDefaultJsonMediaType() which defaults to true. Configuring this to false allows to still use HAL as default media type in case no Accept header is set or it is set to */*. The flag decides what to return when an Accept header is set to application/json.
Major overhaul of mapping detection in RepositoryRestHandlerMapping. We now correctly map URIs if a base URI is configured via RepositoryRestConfiguration.
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.
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.
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.
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.

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.
Related pull request: #125.
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.
Original pull request: #126.
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.
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.

@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.
This commit introduces support for HAL rendering and making it the default rendering option. The configuration now registers an additional MappingJackson2HttpMessageConverter with the according HAL modules registered and makes this the default JSON renderer if the default media type is configured to HAL (which it is by default). To change this, set RepositoryRestConfiguration.setDefaultMediaType(…) back to application/json.
Refactored the PersistentEntityJackson2Module to turn the PersistentEntityResource into it's correct shape (turning associations into links) and the delegate to the default rendering, so that the HAL customizations provided by Spring HATEOAS can kick in. Adapted test cases to the change in default representation format.
Upgraded to Jackson 2.3.0, Spring 3.2.6 and Spring HATEOAS 0.9.0.BUILD-SNAPSHOT. Upgraded to Gradle 1.10.
Removed the attempt to add a link to the response for non-associations. Switched to the usage of Simple(Property|Association)Handlers for simplified generics.
Made RepositoryInvokerFactory an interface and renamed the previously existing implementation class to DefaultRepositoryInvokerFactory. Removed instantiation of the class from ResourceMetadataHandlerMethodArgumentResolver to keep the logic which implementation to use solely in the configuration.
Set order of RepositoryRestHandlerMapping to LOWEST_PRECEDENCE - 100 to give core Spring Framework components the chance to hook into the right place in the chain.
Refactored RepositoryRestHandlerMapping to really check for the exposed path and added test cases for handler method resolution.
PersistentEntityJackson2Module now entirely relies on the property mapping to do the right thing for link creation. The PropertyResourceMapping now returns the property name for both rel and path.
Merged core and repository modules into core. Renamed some packages for consistency in naming and in preparation to break up some package cycles. Removed @BaseUri and the according resolver. Refactored controllers a bit to have more reusable chunks of code.
Simplified new RepositoryMappings infrastructure. Integrated EvoInflectionRelProvider to build collection resource rels. Bumped version number to 2.0 as we're going to break backwards compatibility with the next release to straighten out the rel construction and mapping.
Additional changes include:
* Re-wrote the monolithic Controller into separate controller classes that have a more narrow focus.
* Implemented common functionality as a `HandlerMethodArgumentResolver` rather than as a helper method in a controller class.
* Re-implemented JSONP functionality as an HttpMessageConverter rather than inline within a controller class.
* Updated to Jackson 2 for all JSON handling.
* By relying on spring-data-commons, spring-data-rest now handles all supported Repository types: JPA, MongoDB, and GemFire.
Added support for MongoDB and GemFire repositories by relying on spring-data-commons to provide the metadata rather than maintaining internal metadata information that is store-specific.
Replaced Spock spec tests with JMock unit and integration tests. Started integrating Jetty 8 into the testing so MVC testing can be done against a live server.
