#EnableScheduling in Spring - spring

Question

I am new to Spring Boot. Wanted to enable #EnableScheduling and #Scheduled in my Spring Boot application. Have written as below but how do I call it.
#EnableScheduling
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}

Answer 1

We can use Spring #Scheduled annotation .Below is the code to use in
Spring Boot.
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
#SpringBootApplication
#Configuration
#ComponentScan
#EnableAutoConfiguration
#EnableScheduling
public class Application extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
private static Class<Application> applicationClass = Application.class;
}
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
#Component
public class ScheduledTasks {
#Scheduled(cron = "0 39 00 * * ?")
public void scheduleFixedDelayTask() {
System.out.println("Fixed delay task - " + System.currentTimeMillis()/1000);
}
}
Output in console :
Fixed delay task - 1482952140

There is a good tutorial about your problem: https://spring.io/guides/gs/scheduling-tasks/
You need to annotate application with #EnableScheduling:
#EnableScheduling
public class SpringGuideApplication {
public static void main(String[] args) {
SpringApplication.run(SpringGuideApplication.class, args);
}
}
and then in your class:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.text.SimpleDateFormat;
import java.util.Date;
#Component
public class Scheduler {
private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
private static final Logger log = LoggerFactory.getLogger(Scheduler.class);
#Scheduled(fixedRate = 10000)
public void reportCurrentTime() {
log.info("Scheduler: the time is now {}", dateFormat.format(new Date()));
}
}
