Reactive MongoDB repository can now be composed from Project Reactor and RxJava types for method arguments and return types. Query methods and methods from the base/implementation classes can be invoked with a conversion of input/output types.
- Remove dropDups assertion as the MongoDB 3 driver does no longer provide dropDups even if running agains a MongoDB v2.6.7.
- Remove mongo-next build profile as we're based on the Mongo 3 driver now.
- Map update object and merge set operations.
We use the Document API when interacting with the MongoDB Java Driver. This allows us to make use of new features and enables us to use the Codec API and prepares the project for future enhancements concerning the drivers the reactive API.
Upgraded to Spring Data Build parent 2.0 snapshots and Spring Data Commons 2.0 snapshots. Removed obsolete distribution key property. Removed obsolete template.mf.
We now use more type information to create a better empty collection in the first place. The previous algorithm always used an empty HashSet plus a subsequent conversion using the raw collection type. Especially the latter caused problems for EnumSets as the conversion into one requires the presence of component type information.
We now use Spring's collection factory and more available type information to create a proper collection in the first place and only rely on a subsequent conversion for arrays.
We now make sure not to eagerly attempt to convert given query parameters into a mongo specific format by calling toString() the query object, but rather delegate this to another step later in the chain.

We now make sure to comply to the API requirements of mongo-java-driver 3.4 (in current beta1) by using empty DBObjects instead of null, ignoring non appropriate replication settings and cleaning up tests after execution.

The methods in MongoTemplate inserting a batch of documents previously only returned database generated identifiers, more especially ObjectId ones. This caused non-ObjectId identifiers potentially generated by other parties — i.e. an event listener reacting to a BeforeSaveEvent — not being considered for source object identifier population.
This commit adds a workaround augmenting the list of database generated identifiers with the ones actually present in the documents to be inserted. A follow-up ticket DATAMONGO-1519 was created to track the removal of the workaround in favor of a proper fix unfortunately requiring a change in public API (so a 2.0 candidate only).

SpringDataMongodbQuery is exposed publicly in QuerydslRepositorySupport, that's we've got to make it public to make sure class to the exposed methods from outside the package actually compile.

Opened up Meta attributes to now allowing usage of more than one cursor option via dedicated enum.
new Query().noCursorTimeout();
and
interface PersonRepository extends CrudRepository<Person, String> {
@Meta(flags = {CursorOptions.NO_TIMEOUT})
Iterable<Person> findBy();
}
Original Pull Request: #390
We now allow setting noCursorTimeout for queries using `Query` and `@Meta`.
Query query = new Query().noCursorTimeout();
and
interface PersonRepository extends CrudRepository<Person, String> {
@Meta(noCursorTimeout = true)
Iterable<Person> findBy();
@Meta(noCursorTimeout = true)
Stream<Person> streamBy();
}

We now accept String data types for boolean flags in XML configurations. Boolean data types in the XSD don't allows use of property placeholders even if the resolved value could be converted to boolean. Affected fields by this change are:
* `<mongo:repositories create-query-indexes=… />`
* `<mongo:options ssl=…/>`
* `<mongo:client-options ssl=… />`

Previously we created a default bean definition for MongoMappingContext if none was present in the application context. That lookup for an existing one unfortunately comes too early, especially with Spring Boot in place. This then caused the MappingContext not being aware of the custom conversions and simply types registered by Boot.
We now removed the defaulting relying on a MappingMongoConverter being present in the Application context (which usually is the case for the usage with AbstractMongoConfiguration or the XML <mongo:mapping-converter /> alternative. We use that bean to lookup the MappingContext.
We now use DbObjectAccessor also for preliminary inspections of the source DBObject (e.g. whether a value is present at all). Previously we operated on the DBObject directly which caused issues with properties mapped to nested fields as the keys weren't exploded correctly and thus the check always failed.
By turning `AggregationExpression` public we allow adding custom expressions without workarounds. It is now possible to create eg. `ProjectionOperation` like:
ProjectionOperation agg = Aggregation.project()
.and(new AggregationExpression() {
@Override
public DBObject toDbObject(AggregationOperationContext context) {
DBObject filterExpression = new BasicDBObject();
filterExpression.put("input", "$x");
filterExpression.put("as", "y");
filterExpression.put("cond", new BasicDBObject("$eq", Arrays.<Object> asList("$$y.z", 2)));
return new BasicDBObject("$filter", filterExpression);
}
}).as("profile");

We now take potential registered converters for enums into account when serializing path expressions via SpringDataMongodbSerializer.
Original pull request: #388.
Favor usage of List over BasicDBList.
Rename ProjectionOperation.transform to applyCondition.
Add missing author and since tags, remove trailing white spaces and fix reference documentation headline clash.
Original Pull Request: #385
We now support $cond and $ifNull operators for projection and grouping operations. ConditionalOperator and IfNullOperators are AggregationExpressions that can be applied to transform or generate values during aggregation.
TypedAggregation<InventoryItem> agg = newAggregation(InventoryItem.class,
project().and("discount")
.transform(ConditionalOperator.newBuilder().when(Criteria.where("qty").gte(250))
.then(30)
.otherwise(20))
.and(ifNull("description", "Unspecified")).as("description")
);
corresponds to
{ "$project": { "discount": { "$cond": { "if": { "$gte": [ "$qty", 250 ] },
"then": 30, "else": 20 } },
"description": { "$ifNull": [ "$description", "Unspecified"] }
}
}

We now propagate the PersistentEntity when mapping nested keywords so that the criteria mapping chain for nested keywords and properties has now access to the PersistentEntity and can use configured field names.
Previously the plain property names have been used as field names and potential customizations via @Field have been ignored.

Replace boolean flag in convertAndJoinScriptArgs with literal. Joined args are rendered to JavaScript and require always string quotation.

Setting the value for the identifier property is an explicit step in MappingMongoConverter and always executed if the type to be created has an identifier property. If the source document doesn't contain an _id field (e.g. because it has been excluded explicitly) that previously caused null to be set on the identifier. This caused an exception if the identifier property is a primitive type.
We now explicitly check whether the field backing the identifier property is actually present in the source document and only explicitly set the value if so.
Introduced AbstractMongoConfiguration.getMappingBasePackages() to return multiple ones over the previously existing ….getMappingBasePackage(). The former is now used by the code triggering the scanning using what the latter returns by default.
We now allow direct usage path.eq(…) on id properties of db referenced objects. This allows to write the query as person.coworker.id.eq(coworker.getId()) instead of person.coworker.eq(coworker). This helps building the query using just the plain id not having to actually create new object wrapping it.
