APIs (as popularized by CompletableFuture and ReactiveX) that allow declarative composition of asynchronous logic. At the programming-model level, Java 8 enabled Spring WebFlux to offer functional web Reactive Streams is a small spec (also adopted in Java 9) that defines the interaction between asynchronous components with back pressure. For example a data repository (acting as Publisher) can produce application is to check its dependencies. If you have blocking persistence APIs (JPA, JDBC) or networking APIs to use, Spring MVC is the best choice for common architectures at least. It is technically

Method Argument Description @Payload The payload of the request. This can be a concrete value of asynchronous types like Mono or Flux. Note: Use of the annotation is optional. A method argument that is to be serialized as response payloads. That can be asynchronous types like Mono or Flux, a concrete value, or either void or a no-value asynchronous type such as Mono. 15 The RSocket interaction Cardinali ty Description 1 Either an explicit value, or a single-value asynchronous type such as Mono. Many A multi-value asynchronous type such as Flux. 0 For input this means the method does not have
