Introduction

jersey-ext-reactor is a simple extension for Jersey which makes it possible to return Reactor types (currently Mono and Flux) directly from your Jersey resource endpoints while preserving asynchronous processing. This allows you to use Reactor without being stuck using Spring Webflux controllers or being resigned to add boilerplate to every resource method to subscribe to the Mono/Flux and interact with @Suspended AsyncResponse explicitly.

How to:

Add the coordinates to your build.gradle file

implementation "io.github.chrisribble:jersey-reactor-server:0.0.4"

Register the feature in your Jersey config:

register(ReactorServerFeature.class);

See example directory for complete demonstration in a Spring Boot 3 application.
