[Spring] cron으로 스케쥴링 구현하기

스케줄러 service를 하나 만들어주자

package business.com.api;

import org.springframework.stereotype.Service;

@Service
public class SchedulerService {
	
	public void scheduleRun(){
		System.out.println("조금 떨린다...");
	}
}

 

 

 

 

 

나는 context-scheduler.xml를 하나 만들어서 이 안에  cron설정을 했다

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
                        http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd
                        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd">
    <bean id="apiScheduleService" class="business.com.api.SchedulerService" />
    <task:scheduler id="gsScheduler" pool-size="10" />
    <task:executor id="gsTaskExecutor" pool-size="10" />
    <task:annotation-driven executor="gsTaskExecutor"
    scheduler="gsScheduler" />
</beans>

 

 

 

 

 

 

package business.com.api;

//추가//
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;

@Service
public class SchedulerService {
	
    //추가//
	@Scheduled(cron="*/30 * * * * *") 
    public void scheduleRun(){
		System.out.println("조금 떨린다...");
	}
}

scheduled 어노테이션을 추가해주고 크론을 설정해준다

30초마다 한번씩 조금 떨리는 메시지를 날려보자..

 

 

 

잘 뜨네예...

기본 설정완료

여기서 이제 원하는 로직을 추가해주면된다
