Configuring Scheduled Tasks with Annotation Metadata

To make your application’s tasks configurable, you can use annotation metadata and property placeholder configuration. For example:

Allow tasks to be configured

    @Scheduled(fixedRate = "${my.task.rate:5m}",
            initialDelay = "${my.task.delay:1m}")
    void configuredTask() {
        System.out.println("Executing configuredTask()");
    }

Allow tasks to be configured

    @Scheduled(fixedRate = '${my.task.rate:5m}',
            initialDelay = '${my.task.delay:1m}')
    void configuredTask() {
        println "Executing configuredTask()"
    }

Allow tasks to be configured

    @Scheduled(fixedRate = "\${my.task.rate:5m}",
            initialDelay = "\${my.task.delay:1m}")
    internal fun configuredTask() {
        println("Executing configuredTask()")
    }

The above example allows the task execution frequency to be configured with the property my.task.rate, and the initial delay to be configured with the property my.task.delay.
