The Quarkus core Technologies:
  • Quarkus uses RESTEasy for the JAX-RS endpoint. 
  • Quarkus uses Vert.x and Netty at its core, providing reactive and non-blocking HTTP layer. 
  • Quarkus uses JBoss Log Manager as the default logging framework. 
  • Quartus utilizes a modified version of Undertow  that runs on top of Vert.x 
  • Quarkus uses SmallRye Config, implementation of Eclipse MicroProfile Config, for configuration data.
For testing:
  • Quarkus uses JUnit 5 for testing. 
  • Quarkus uses rest-assured to test HTTP endpoints.

2. Quarkus JAX-RX endpoint

package com.knf.endpoint;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;


@Path("/api/hello")
public class EndPoint {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getUsers() {
return "Hello World";
}
}

3 . Testing

Build application  jar file: mvn clean package


Start application: java -jar quarkus-run.jar
Open the browser and hit the endpoint localhost:8080/api/hello
