1.创建java类SchedulingConfig

2.配置@Configuration注解

3.打开任务调度@EnableScheduling

4.方法名上写调度周期配置@Scheduled(cron = “0/20 * * * * ?”) // 每20秒执行一次

具体代码如下

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
 * 1.配置@Configuration注解
 * 2.打开任务调度@EnableScheduling
 * 3.方法名上写调度周期配置@Scheduled(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()");
    }

}

5.启动查看
