Implementing input adapters with RESTEasy Reactive

RESTEasy Reactive is a JAX-RS implementation that supports both imperative and reactive HTTP endpoints. Such an implementation integrates with Vert.x, which is a toolkit that we can use to build distributed Reactive systems. RESTEasy Reactive and Vert.x work together in Quarkus to provide Reactive capabilities.

To understand what a Reactive endpoint looks like, we will integrate RESTEasy Reactive with the input adapters of the topology and inventory system.

Let’s start by configuring the required Maven dependencies:

<dependencies>
  <dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-resteasy-reactive</artifactId>
  </dependency>
  <dependency>
