spring boot 集成 quartz

分四步

1：导入pom

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
    <version>2.1.6.RELEASE</version>
</dependency>

2：创建java

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class QuartzDemo{

    @Scheduled(fixedRate = 5000)
    public void test(){
        System.out.println("每隔5秒执行一次");
    }
    @Scheduled(cron = "0 0/5 * * * ?")
    public void test1(){
        System.out.println("每隔5分钟又执行一次");
    }
}

3：启动类配置

@EnableScheduling

4：启动服务
