Inject @Scheduled fixedRate value from Spring Boot application.yml file

Question

I know I can inject the value from properties file with the following syntax:

@Scheduled(fixedRate=${myRate})
public void getSchedule(){
    System.out.print         


        

Answer 1

In my application.properties (YAML) I put this

console:
    fetchMetrics: 5000

Then in my simple Task class I push the definition :

@Scheduled(fixedRateString ="${console.fetchMetrics}", initialDelay=1000)
public void fetchMetrics() {
    logger.info("What's up ?");
}

Please notice that fixedRate expects a long and you want to inject a placeholder, you will need fixedRateString
