springboot schedule


1.在application.properties配置文件中添加

#延迟5秒
jobs.fixedDelay=5000
#每隔2秒
jobs.cron=*/2 * * * * ?

2.新建一个ScheduleTask类

import java.text.SimpleDateFormat;
import java.util.Date;

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

@Component
public class ScheduleTask {

private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

@Scheduled(fixedDelayString = "${jobs.fixedDelay}")
public void getTask1() {
System.out.println("延迟5秒,当前时间:" + dateFormat.format(new Date()));
}

@Scheduled(cron = "${jobs.cron}")
public void getTask2() {
System.out.println("每隔2秒执行一次,当前时间:" + dateFormat.format(new Date()));
}
}

3.在springboot启动类中添加启动schedule注解,如下

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class SpringbootApplication {

public static void main(String[] args) {
SpringApplication app=new SpringApplication(SpringbootApplication.class);
app.run(args);

}
}


4.启动之后效果如下
