1. Setup Application

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

/**
 * Created by tmichels on 9/20/15.
 */

@SpringBootApplication
@EnableScheduling
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class);
    }
}

2. Setup Scheduler

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.util.List;
import java.util.Set;

/**
 * Created by tmichels on 9/18/15.
 */

@Component
public class Scheduler {

    private static final Logger logger = LoggerFactory.getLogger(Scheduler.class);

    @Scheduled(cron = "0 0 13 * * *")
    public void buyHighPercentageReturnNotes(){
       System.out.println("Scheduler is running");
    }
}

3. Add Spring Boot dependency

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.2.6.RELEASE</version>
    </parent>
  <dependencies>
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter</artifactId>
      </dependency>
  </dependencies>

4. Add Procfile

worker: java $JAVA_OPTS -jar target/*.jar

5. Scale Heroku worker

heroku ps:scale worker=1
