Choice of placeholder "mode" is determined by the syntax used inside the query, early during repository instantiation.
An IllegalArgumentException is thrown if both named and positional parameters are used.
The generated view's default map function now emits meta.id so that CRUD findAll(ids) works.
The default value for the view name is now "all".
The ViewIndexed isn't documented as applicable to METHODs (deferred feature).
This change allows simple projections to types long, boolean, String when an inline N1QL query uses an aggregation function like AVG, COUNT.
The projection's result must be a single row with a single key/value pair in the N1QL response. Only the value gets returned.
Added an integration test for custom method customization.
Moved the integration test for base class customization.
Put the samples in the documentation in a new "Changing Repository Behaviour" section.
This fixes the fact that EnableCouchbaseRepository(repositoryBaseClass = Something.class) was ignored.
Now using reflection to choose the target implementation. Note that custom base classes MUST extend SimpleCouchbaseRepository (or its subclass N1qlCouchbaseRepository).
An example in the form of an integration test has been added in src/integration/java/org/springframework/data/couchbase/repository/base/RepositoryBaseTest.java.
So far with geo queries a bounding box approximation was performed on Circle and Polygon queries (since Couchbase internally only supports Bounding Box queries).
It was confusing since in previous iteration it was up to the user to remove these false positives "after the fact" in code calling the repository.
This change allows for the framework to retain enough information to perform false positives elimination automatically and transparently for the user.
The configuration step made it look like a new mapping was necessary in overrides, whereas it is actually possible and clearer to mutate the base mapping.
Added a convenience method to get the MappingContext from the repository mapping.
Main indexes (ie indexes that can be used by repositories to retrieve ALL the documents of a particular entity type) are covered.
Repository interfaces can be annotated with an annotation for each type of main index that can be automatically created.
The IndexManager is responsible for creating said indexes (potentially skipping creation if an index is already in place, or if the IndexManager has been configured to skip it, see constructor).
Since IndexManager is created as a bean (either in JavaConfig or xml), there can be a different instance eg. in Prod vs Dev.
Added doc and integration test.
Renamed package core.view to core.query since it now contains various non-view related annotations and classes.
Detection whether or not reduce should be activated is now centralized. Triggers are:
- using the count prefix instead of find in method name
- setting reduce = true in the View annotation explicitly.
The reduce can thus be returning any kind of value (added an integration example with _stats), which is now properly documented.
Added the step of parsing SpEL expressions delimited by ${ } in StringN1qlBasedQuery, then the actual evaluation of each expression.
Refactored StringN1qlBasedQuery to use SpEL across the board, including for N1QL specific placeholders (SELECT-FROM, WHERE filter, etc...).
Refactored StringN1qlBasedQuery to use local methods rather than static methods, and amended the unit tests accordingly (using mocks).
Refactored getStatement and getCountStatement so they can see the parameters passed in at runtime.
Added unit tests + integration test.
Added SpEL support example in documentation.
Add support for geo queries through the use of Spatial Views. This needs the query method to be annotated with @Dimensional (or a meta-annotation of it that is runtime retained).
See SpatialViewQueryCreator javadoc for supported part types and corresponding expected arguments (to be documented).
In a nutshell WITHIN Box (other shapes supported but approximated to bounding box), NEAR Point+Distance (approximated to bounding box), plus a few simple operators for dimensions beyond 2.
When approximating, a DEBUG log is made along the logging of the query.
Conversion methods from Shapes to bounding boxes are done in a GeoUtils class.
Unit and Integration test of the feature.
Added documentation for @Dimensional query derivation.
Added a configuration bean that allows to express what CouchbaseOperations each repository should use, individually or by domain type.
Added documentation for the feature in repository section.
Add support for Page / Slice in N1QL query derived methods.
Add PagingAndSortingRepository support through a N1qlCouchbaseRepository implementation. It will only be used as a base if N1QL is actually available on the cluster.
Refactor out some steps of entity related query creation in a N1qlUtils class, so that they can be also done eg. in repository base classes.
Add tests for both N1qlUtils and the N1qlCouchbaseRepository.
Document that PagingAndSortingRepository is supported provided N1QL is available on the Couchbase cluster.
The generated N1QL queries currently don't filter on the type at all.
Add a criteria to the WHERE clause that checks the field holding type information is matching the entity fully qualified class name.
Add a placeholder for inline N1QL queries that can be replaced by the same type information criteria.
Additionally to resolving a POJO attribute to JSON field name, the path conversion step will also escape each part of the doted path, in order to avoid problems with N1QL keywords.
The consistency to apply on generated view queries (Stale) and N1QL queries (ScanConsistency) can now be chosen via the configuration, through a more abstract Consistency enumeration.
It is accessed from the CouchbaseOperations interface but is used in the repository only. In xml, the consistency attribute is on the couchbase:template element (string value of the enum to be passed in).
Documentation has been amended to describe this feature.
The @Field annotation has been removed in favor of the one from the Couchbase SDK.
Similarly, CouchbasePersistentEntity now recognize the SDK's @Id annotation. Note that if both Spring Data and Couchbase @Id are present (on two distinct fields), the one from Spring Data will be taken into account.
Detect N1QL is not available at configuration time for the repositories and at runtime for the template. This throws a UnsupportedCouchbaseFeatureException.
The ClusterInfo is captured at bootstrap and used to determine if the feature is available. The xml configuration will need the ClusterInfo-related credentials to be provided explicitly.
When deriving a query, use the CouchbaseConverter to transform the parameters for fields that would be converted upon storage.
Reworked the DateConverters so that reading conversion is done from any Number (since N1QL may return longs in Double scientific notation for example).
@View can now trigger a basic query derivation. If viewName's explicitly
set, query derivation is attempted. Otherwise, no derivation is made but
instead the viewName is guessed by using the method name and removing a
"find" or "count" prefix.
Methods prefixed with "count" (and in general detected as count
projections) will trigger a reduce on the view.
The @N1QL annotation was changed to @Query, for discoverability and also
convey that this is now the preferred method.
Order is now view if @View present, N1ql inline if @Query present with
a Statement, N1ql query derivation if @Query without attribute or no
annotation.
@View can be without attribute in order to compute the view
and design document from method name.
Abstracted the N1QL-based variants in AbstractN1qlBasedQuery. This implementation doesn't recognize QueryParams or QueryPlan anymore in the method parameters so that the method signatures are not store-dependent.
Added query derivation from PartTree to N1QL query, using N1qlQueryCreator.
Unit tested the mapping between a Part.Type and the corresponding N1QL Expression.
The annotation allows to execute N1QL queries that are provided inline. For ease of use, one can use the placeholder $SELECT_ENTITY$ instead of writing the SELECT and FROM clauses.
QueryParams passed in as a method parameter will be used to enrich the Query. Other parameters on the annotated method will be used as values for positional placeholders in the statement.
The template's findByN1QL now expect enough data to reconstruct the full CouchbaseDocument (including ID and CAS), the ad hoc version of it has been renamed findByN1QLProjection.
Adaptation were made to use SDK 2.0:
- Reworked the configuration approach (more parts to be configured, like Environment, Cluster and Bucket)
- Added a new xml schema for configuration of 2.0 version
- Adapted the template
- Added N1QL support in the template (findByN1QL)
- Removed the cache package
- Adapted the repository
- Better separated Unit Tests from Integration Tests
All integration and unit tests pass, except one (SimpleCouchbaseRepositoryTests.shouldFindCustom).
Customisation of a ViewQuery will be addressed in another ticket.
