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.
- 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
