package cn.wuyang.springboot.config; 
 
import org.springframework.context.annotation.Configuration; 
import org.springframework.scheduling.annotation.EnableScheduling; 
import org.springframework.scheduling.annotation.Scheduled; 
 
/** 
 * 定时任务 
 * [email protected] 
 * [email protected] 
 * [email protected](cron = "0/20 * * * * ?") // 每20秒执行一次 
 * @author wuyang 
 * 
 */ 
@Configuration 
@EnableScheduling 
public class SchedulingConfig { 
    @Scheduled(cron = "0/20 * * * * ?") // 每20秒执行一次 
    public void SchedulingTest() { 
        System.out.println(">>>>>>>>> SchedulingConfig.scheduler()"); 
    } 
 
}
