JHeroku-keep-alive

This minimalistic java library brings a powerful annotation to your Java Spring Boot application and prevents your app from sleeping on the free Heroku plan!

Where do I get this library

To use this library in your Web Application use it from our GitHub packages: https://github.com/orgs/PickwickSoft/packages

Usage

JHeroku-keep-alive provides the following annotation @HerokuKeepAlive

Use this annotation like that:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.pickwicksoft.jherokukeepalive.HerokuKeepAlive;

@HerokuKeepAlive
@SpringBootApplication
public class WebApp {

    public static void main(String[] args) {
        SpringApplication.run(WebApp.class, args);
    }
}

How does it work?

The annotation adds a spring service to your application that starts a GET request to https//:localhost:8080 every five minutes wich prevents the Heroku machine from shutting down.
