refer on bean.property in @Scheduled by SpEL

Question

I'm going to set fixedRate-value in @Scheduled dynamically.

For this aims I'm trying to use SpEL-abilities as following:

@AllArgsConstructor
public class ContentSender {

    @Scheduled(fixedRateString = "#{OuterProperties.rateForMessageReading}")
    public void contentModelMessageSource() throws IOException {       
    }
}

Class with target-property:

@Getter
@Setter
@ConfigurationProperties("app")
public class OuterProperties {
    private static final long WAITING_INTERVAL = 100;
    private long rateForMessageReading;
}

By as a result on the deploy-stage I receive:

SpelEvaluationException: EL1008E: Property or field 'outerProperties' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext' - maybe not public or not valid?

What am I doing wrong?

Answer 1

Problem is that I use only @ConfigurationProperties. When I add @Configuration problem is gone.

@Getter
@Setter
@Configuration
@ConfigurationProperties("app")
public class OuterProperties {
    private static final long WAITING_INTERVAL = 100;
    private long rateForMessageReading;
}
