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";
}
}

Build application  jar file: mvn clean package



Start application: java -jar quarkus-run.jar

 By default, the Quarkus application starts on HTTP port 8080.


Change the HTTP Port

Method 1:

In Quarkus, we can use the property quarkus.http.port to override the HTTP port (the default value is 8080). If this property is set in application.properties then that value will be used.
ie, 
quarkus.http.port=9080
 
Now, the Quarkus application starts on HTTP port 9080
 
Method 2:

When running a Quarkus application in JVM mode you can set the port using the quarkus.http.port System property. 
For example:  
java -Dquarkus.http.port=8081 -quarkus-run.jar

Now, the Quarkus application starts on HTTP port 8081
