Spring's @Scheduled annotation's fixedDelay property can be used to execute the annotated method with a fixed period between the end of the last invocation and the start of the next.
Example
Using @Scheduled annotation with fixedDelay
In this example we are creating two @Scheduled methods, one with fixedDelay and other with fixedDelayString
package com.logicbig.example;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.time.LocalTime;
@Component
public class MyBean {
@Scheduled(initialDelay = 1000, fixedDelay = 1000)
public void runTask() {
System.out.printf("Running scheduled task " +
" thread: %s, time: %s%n",
Thread.currentThread().getName(),
LocalTime.now());
}
@Scheduled(initialDelay = 1000,
fixedDelayString = "2000")
public void runTask2() {
System.out.printf("Running scheduled task 2" +
" thread: %s, time: %s%n",
Thread.currentThread().getName(),
LocalTime.now());
}
}
Main class
package com.logicbig.example;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
@ComponentScan
@EnableScheduling
@Configuration
public class ScheduledExample {
public static void main(String[] args) throws InterruptedException {
AnnotationConfigApplicationContext context =
new AnnotationConfigApplicationContext(
ScheduledExample.class);
}
}
