The Jackson(2)ModuleRegisteringBeanPostProcessor now uses postProcess*Before*Initialization to make sure, afterPropertiesSet() has not been called on the target components which might have propagated the original HttpMessageConverters into other internal components.
With this fix, adding the HttpMessageConverter for HAL is added before the call and thus will be propagated to downstream components.
UriTemplate.expand(Map) not takes a Map<String, ? extends Object> to make sure Link.expand(Map) binds to the correct method. Previously it was bound to the method overload taking an Object vararg which caused an invalid expansion.
To correctly resolve the rel for a proxied class we need to build up relation types for, HalEmbeddedBuilder now uses Spring's AopUtils.getTargetClass(), which will use the object's getTargetClass() method in case it implements TargetClassAware.
To get consistent representations rendered for single-item collections and multi-item collections, we now use an enforceEmbeddedCollections flag in the Jackson 2 HAL module. Adapted HalEmbeddedBuilder to respect that setting and exposed it via the HandlerInstantiator for user level customization.
Changed RelProvider.getSingleResourceRel(…) to getItemResourceRel(…).
Request parameters variables {?…} and continued ones {&…} are now combined by TemplateVariables. Improved detection of the base URI and adapted the rendering logic accordingly. UriTemplates can now be augmented with additional TemplateVariables.
Added equals(…) and hashCode() methods for TempalteVariables.
Changed `getCurieInformation(…)` to receive a `Links` instance with the previously added links and is forced to return a collection of curies so that multiple ones can be resolved transparently.
Made Curie value class protected to be able to reuse it from extensions of DefaultCurieProvider. Switched to the custom HATEOAS UriTemplate instance instead of the standard Spring MVC one.
Polished JavaDoc of DefaultCurieProvider. Removed some of the deprecation warnings that were introduced by the upgrade to Jackson 2.3. Polished (read: reactivated) some test cases and slightly changed the internals of UriTemplate works. Added TemplateVariables.asList().
Updated change log so far. Upgraded to latest dependency versions. Polished porject information in pom.xml. Added Spring dependencies that we directly depend on. Adapted test cases to changes in Jackson 2 output format. Updated ChangelogCreator to latest milestone and repository URI.
TempalteVariable is now a standalone class. Introduced TempalteVariables wrapper to allow easy collecting of TempalteVariable instances and rendering them in the shortest possible way.
MethodParameters now has a getParametersOfType(…) method to access parameters by type. Also, it now checks for the presence of Spring 4 and automatically uses the improved ParameterNameDiscoverer which will be able to discover interface method parameter names on Java 8.
Added LinkTemplate domain type that can deal with URI templates as defined in http://tools.ietf.org/html/rfc6570. We currently support /, ?, & and # variables up to level 3 of the spec (multiple parameter definitions). The templates can be expanded to a Link instance.
Added the necessary HAL mixins to render the instances as specified.
If the method arguments handed into a dummy controller method invocation are required but null we now throw an exception as we cannot build a URI that hits the very same method in the very same way. Based on that, we now inspect @RequestParam annotated parameters for null values, allow them but don't bind a parameter for them anymore.
Both _links and _embedded are now only rendered if there's actual content to be rendered. The curies link is now always rendered as array as specified.
The LinkDiscoverer interface is now a Plugin<MediaType> to allow selecting a discoverer per media type. We also provide a LinkDiscoverers wrapper around a PluginRegistry for easier injection.
Dropped DefaultLinkDiscoverer as the above mentioned changed prohibits the usage of a discoverer without a media type. Clients that previously used DefaultLinkDiscoverer should switch to JsonPathLinkDiscoverer with a custom JsonPath expression and media type.
@EnableHypermediaSupport now supports multiple HypermediaType values set to be able to set up support for multiple hypermedia formats. Admittedly, the only currently supported type is HAL but we prepare for the addition of other (e.g. Collection/JSON or the like). We changed the infrastructure setup taken care of by @EnableHypermediaSupport to not enrich all ObjectMapper instances with our HAL modules but explicitly register an ObjectMapper with the application context and then registering a custom MappingJackson(2)HttpMessageConverter with the HandlerAdapter instances present in the ApplicationContext. We skip the registration if an already registered MJ2HMC has an ObjectMapper already supporting the Spring HATEOAS mixins.
Removed some compiler warnings.
Introduced CurieProvider interface as well as a DefaultCurieProvider that can be registered as Spring Bean to enable Links being rendered in a curie namespace and an additional curie link exposing the metadata of how to lookup the rel definition.
Deprecated Jackson 1 integration. Added helper class to find out whether a relation type is defined by the IANA.
PageMetadata doesn't reject empty pages anymore if they're used with 1-indexed Pageables. Also tweaked the assertions to only reject negative values for now.
MethodParameters can now get an AnnotationAttribute configured that will be inspected for parameter name lookup. If it's not set or no annotated parameter is found we fall back to the standard behavior of MethodParameter and use a LocalVariableTableParameterNameDiscoverer.
We need to have a different XML element name for PagedResources as it can be used as root element and JAXB cannot tell the difference between Resource and PagedResource otherwise.
