Reading from application.properties: Attribute value must be constant

Question

In the below-given code I get the compilation error Attribute value must be constant. How to deal with it?

@Component
public class ScheduledTasks {

    @Value("${example}")
    String message;

    @Value("${update.rate}")
    final static long rate;

    @Scheduled(fixedRate = this.rate)
    public void update()
    {
        System.out.println(this.message);
    }
}

Answer 1

Change to:

@Scheduled(fixedRateString = "${update.rate}")
public void update()
{
    System.out.println(this.message);
}
