@scheduled 定时任务不执行，没有使用xml配置

原代码

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

@Component
public class TestScheduler {

	@Scheduled(cron = "0/5 * * * * ?")
	public void demo1() {
		System.out.println("==========");
	}
}

启动后发现定时任务未执行

添加@EnableScheduling注解

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

@Component
@EnableScheduling
public class TestScheduler {

	@Scheduled(cron = "0/5 * * * * ?")
	public void demo1() {
		System.out.println("==========");
	}
}

@EnableScheduling注解可以让Spring可以进行任务调度，功能类似于Spring的xml命名空间<task:*>
