1. 현상

org.xml.sax.SAXParseException; lineNumber: 29; columnNumber: 53; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'task:scheduler'.

2. 설정

servlet-context.xml 파일에...

xmlns:task="http://www.springframework.org/schema/task" 추가된 상태...

3. 원인

xsi:schemaLocation 에도 추가되어야 한다...

http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task.xsd

4. 참고 소스

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class SchedulerTest {
	@Scheduled(cron = "0 15 * * * *")
	public void scheduleTest1() {
		System.out.println("schedule1 - xx:15:00");
	}

	@Scheduled(cron = "0 25 * * * *")
	public void scheduleTest2() {
		System.out.println("schecule2 - xx:25:00 ");
	}
	
	@Scheduled(cron = "0 35 * * * *")
	public void scheduleTest3() {
		System.out.println("schecule2 - xx:35:00 ");
	}
	
	@Scheduled(cron = "0 45 * * * *")
	public void scheduleTest4() {
		System.out.println("schecule2 - xx:45:00 ");
	}
}
