The #this and #root variables Functions Bean references Ternary Operator (If-Then-Else) The Elvis Operator Safe Navigation operator Collection Selection Collection Projection Expression templating Classes the bean by calling its constructor reflectively, somewhat equivalent to Java code using the new operator. To specify the actual class containing the static factory method that will be invoked to create the Spring container’s role in regard to a prototype-scoped bean is a replacement for the Java new operator. All lifecycle management past that point must be handled by the client. (For details on the lifecycle

Extensions allow to add custom operators to Flow • Collect operations are suspending functions • map operator supports asynchronous operation (no need for flatMap) since it takes a suspending function parameter reactive.executeAndAwait class PersonRepository(private val operator: TransactionalOperator) { suspend fun initDatabase() = operator.executeAndAwait { insertPerson1() insertPerson2() transactional class PersonRepository(private val operator: TransactionalOperator) { fun updatePeople() = findPeople().map(::updatePerson).transactional(operator) private fun findPeople(): Flow
