In this post, we'll go over how to implement a scheduled task in a Spring Boot application. Spring Boot provides a simple and convenient way to run scheduled tasks.
Spring Boot provides a @Scheduled annotation that can be used on methods to mark them as tasks that should be run periodically. For example, we can use the @Scheduled annotation to run a task every minute:
@Scheduled(cron = "0 * * * * ?")
public void runEveryMinute() {
// do something
}
In the example above, we are using a cron expression to schedule the task. Cron expressions are a convenient way to specify when a task should be run. For more information on cron expressions, see the CronTrigger javadocs.
To run the task in our Spring Boot application, we just need to annotate our main class with the @EnableScheduling annotation:
@SpringBootApplication
@EnableScheduling
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
