SpringBoot WebFlux Annotation-based RestAPIs

Reactive programming is about non-blocking applications. And Spring Framework 5 includes a new spring-webflux module, supports Reactive Streams for communicating backpressure across async components and libraries. So in the tutorial, JavaSampleApproach will guide you through the steps for creating a SpringBoot WebFlux Annotation-based restful APIs.

Reactor – Simple Ways to create Flux/Mono

Reactive Streams is an API and pattern that provides a standard for asynchronous stream processing with non-blocking back pressure. It is also being introduced in Java 9 Flow API with four simple interfaces: Publisher, Subscriber, Subscription and Processor.

But Reactive Streams API is just low level to make practical use in reactive applications. So Reactor Core provides two main implementations of Publisher: Flux and Mono. In this tutorial, we’re gonna know what they are and simple ways to create them.

Java 9 FLow SubmissionPublisher – A Concrete Publisher

JDK 9 provides a concrete Publisher named SubmissionPublisher that acts as a compliant Reactive Streams Publisher relying on drop handling and/or blocking for flow control. In this tutorial, we’re gonna take a look at SubmissionPublisher and an example that generates items for Subscribers.

Java 9 Flow API example – Processor

In previous post, we have general knowledge about Reactive Streams and Java 9 Flow API Components and Behaviour. In this tutorial, we’re gonna look at an example that implements Publisher, Subscriber with Processor as a bridge for reactive programming.
