We now support the following type conversion aggregation operators:
* $convert
* $toBool
* $toDate
* $toDecimal
* $toDouble
* $toInt
* $toLong
* $toObjectId
* $toString

Make sure to place the LazyLoadingProxy early in the mapping process to avoid eager fetching of documents that might then get replaced by the LazyLoadingProxy.

Simplify conditional flow. Replace AtomicReference construction in ChangeStreamEvent with AtomicReferenceFieldUpdater usage to reduce object allocations to streamline lazy body conversion usage. Tweak Javadoc and reference docs.
Original pull request: #576.
We still stick to count for non session operations as countDocuments does not allow geo operators like $near in the filter query. For now we will wait to see if this is resolved within the driver.
Added options to watch an entire database and resume the changestream from a given point in time (UTC).
Original pull request: #576.
Update Javadoc and add reference documentation.
Alter @Meta batchSize default to zero, as negative values bear a special meaning.
Along the lines remove deprecated driver method usage and add deprecations for options about the be removed in subsequent MongoDB server releases.

Allow open/close projection on return type for findAndReplace.
Use default methods for delegation and remove collation from FindAndRemoveOption in favor of the collation set on the query itself.
Update Javadoc and reference documentation.
Original Pull Request: #569
We now support findAndReplace operations through the imperative and reactive Template API to find an object by a query and entirely replace it (except for the _id).
template.findAndReplace(query(where("name").is("Han")), new Person("Luke"))
template.update(Person.class).inCollection(STAR_WARS).matching(query(where("name").is("Han"))).replaceWith(luke).findAndReplace()

Extract count aggregation pipeline setup to AggregationUtil. Fix count extraction if aggregation returns no results. Fix nullability of Query argument in ReactiveMongoTemplate.count(…). Improve synchronization of multi-threaded aggregation count test to prevent commit before all threads have issued a count query and to await thread completion.
Upgrade to MongoDB 4.0.0-rc4.

We now delegate count operations within an active transaction to an aggregation.
Once `MongoTemplate` detects an active transaction, all exposed `count()` methods are converted and delegated to the
aggregation framework using `$match` and `$count` operators, preserving `Query` settings, such as `collation`.
The following snippet of `count` inside the session bound closure
session.startTransaction();
template.withSession(session)
.execute(action -> {
action.count(query(where("state").is("active")), Step.class)
...
runs:
db.collection.aggregate(
[
{ $match: { state: "active" } },
{ $count: "totalEntityCount" }
]
)
instead of:
db.collection.find( { state: "active" } ).count()

Rename QueryUtils method to decorateSort(…) to reflect the nature of the method. Add missing generics. Convert ReactiveMongoRepositoryTests to AssertJ. Add missing verifyComplete() steps to StepVerifier. Slight tweaks to Javadoc and reference docs.
Original pull request: #566.
We now allow to set a default sort for repository query methods via the @Query annotation.
@Query(sort = "{ age : -1 }")
List<Person> findByFirstname(String firstname);
Using an explicit Sort parameter along with the annotated one allows to alter the defaults set via the annotation. Method argument sort parameters add to / override the annotated defaults.
@Query(sort = "{ age : -1 }")
List<Person> findByFirstname(String firstname, Sort sort);

ReactiveMongoOperations.withSession(…) no longer commits transactions if a transaction is active. ReactiveSessionScoped obtained through inTransaction() solely manages transactions and participates in ongoing transactions if a given ClientSession has already an active transaction. Remove ReactiveSessionScoped.executeSingle methods to align with ReactiveMongoOperations.
Add tests. Switch reactive tests to .as(StepVerifier:create) form. Extend documentation.
Original pull request: #560.
We now support Mongo Transactions through the reactive Template API. However, there's no reactive repository transaction support yet.
Mono<DeleteResult> result = template.inTransaction()
.execute(action -> action.remove(query(where("id").is("step-1")), Step.class));

Full editing pass of the Spring Data MongoDB reference guide. I also adjusted index.adoc to work with the changes I made to the build project, so that we get Epub and PDF as well as HTML.
Original pull request: #559.
Rename MongoDbFactoryBase to MongoDbFactorySupport. Add constructor to MongoTemplate accepting the new MongoClient type. Extend Javadoc. Switch tests to use the new MongoTemplate constructor.
Original pull request: #557.
We now accept MongoDB's new com.mongodb.client.MongoClient object to setup Spring Data MongoDB infrastructure through AbstractMongoClientConfiguration. The new MongoClient does not support DBObject anymore hence it cannot be used with Querydsl.
@Configuration
public class MongoClientConfiguration extends AbstractMongoClientConfiguration {
@Override
protected String getDatabaseName() {
return "database";
}
@Override
public MongoClient mongoClient() {
return MongoClients.create("mongodb://localhost:27017/?replicaSet=rs0&w=majority");
}
}

Slightly tweak method names. Document MongoDatabaseUtils usage in the context of MongoTransactionManager. Rename SessionSynchronization constants to align with AbstractPlatformTransactionManager. Slightly tweak Javadoc and reference docs for typos.
Original pull request: #554.
MongoTransactionManager is the gateway to the well known Spring transaction support. It allows applications to use managed transaction features of Spring.
The MongoTransactionManager binds a ClientSession to the thread. MongoTemplate automatically detects those and operates on them accordingly.
static class Config extends AbstractMongoConfiguration {
// ...
@Bean
MongoTransactionManager transactionManager(MongoDbFactory dbFactory) {
return new MongoTransactionManager(dbFactory);
}
}
@Component
public class StateService {
@Transactional
void someBusinessFunction(Step step) {
template.insert(step);
process(step);
template.update(Step.class).apply(update.set("state", // ...
};
});

Remove mapReduce default methods in favor of adding variants through a fluent API at a later stage. Assert mapReduce arguments and remove subsequent null guards. Adapt tests.
Original pull request: #548.
Remove DateFactory and split up tests.
Introduce dedicated Timezone abstraction and update existing factories to apply the timezone if appropriate. Update builders and align code style.
Original Pull Request: #539
Turn instance methods into static ones where applicable. Avoid parameter type array cloning where possible.
Add reference to rework stack-trace inspection in order to throw ClientSessionException. Migrate MongoPersistentEntityIndexCreatorUnitTests to AssertJ. Add tests to verify simple session proxy wrapping on subsequent MongoDbFactory.withSession(…) calls.
Guard ClientSession tests with replica set rule. Remove unused code. Add non-null guards. Add missing Nullable annotations. Slightly tweak Javadoc and reference documentation.
