Look for the latest official release here of the QBit Microservice lib.

Java code for hello world QBit

package com.mammatustech;

import io.advantageous.qbit.admin.ManagedServiceBuilder;
import io.advantageous.qbit.annotation.RequestMapping;

@RequestMapping("/hello")
public class HelloWorldService {

    @RequestMapping("/hello")
    public String hello() {
        return "hello " + System.currentTimeMillis();
    }

    public static void main(final String... args) {
        final ManagedServiceBuilder managedServiceBuilder =
                ManagedServiceBuilder.managedServiceBuilder()
                                     .setRootURI("/root");

        /* Start the service. */
        managedServiceBuilder.addEndpointService(new HelloWorldService())
                .getEndpointServerBuilder()
                .build().startServer();

    }
}
