Spring Boot is an open source Java based framework used to spring boot microservices. It is developed by Pivotal Team and is used to build stand-alone and pr. Calling R2dbcRepository.save () with an object that has an Id assigned issues an update. Without further hints, we don't have a way to know whether the object is new or whether it already exists. Let your Session object implement Persistable. Reactive transactions work only on methods returning Publisher types ( Mono, Flux, Publisher, Flowable ).

R2DBC returns those values in a Result containing a single row with all generated values, which we use to create the Account instance. Once again, we need to adapt the incoming Mono<Publisher<Account>> into a Mono<Account>, so we add a flatMap () to solve this . Next, we commit the transaction in a delayUntil () step.
