启动类上添加 @EnableScheduling

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

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

@Service
public class ScheduledTaskService {

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

    @Scheduled(fixedRate = 5000)
    public void fixedRateTask() {
        System.out.println("fixedRateTask 每5s执行一次: " + dateFormat.format(new Date()));
    }

    @Scheduled(cron = "0 30 14 ? * *")
    public void cronTask() {
        System.out.println("cronTask 每天14点30分执行一次: " + dateFormat.format(new Date()));
    }
}
