@Scheduled annotation fixedDelayString attribute does not resolve SpEL expressions [SPR-14114]

[spring-projects-issues]

Sean Stephenson opened SPR-14114 and commented

I have a @Scheduled method that should execute every N seconds, where N is an interval specified in a config file. Here is how my declaration looks.

@Scheduled(fixedDelayString = "#{${myapp.intervalInSeconds} * 1000}")
public void run() {
// ...
}

Unfortunately, while specifying a property replace expression like "${myapp.intervalInSeconds}" works correctly, using a SpEL expression to convert this to milliseconds does not work. I get the following error message on attempting to start Spring.

Caused by: java.lang.IllegalStateException: Encountered invalid @Scheduled method 'run': Invalid fixedDelayString value "#{10 * 1000}" - cannot parse into integer

Fortunately, this has been addressed for 4.3 already and will therefore be included in tomorrow's 4.3 RC1!
