Christoph Strobl 4cd2935087 DATAMONGO-1920 - Add support for MongoDB 4.0 transactions (synchronous driver). ...

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", // ...
	};
});
