在springboot項目中使用quartz如何實現一個定時任務

@Component
@Configurable
@EnableScheduling
public class ScheduledTasks{

  @Scheduled(fixedRate = 1000 * 30)
  public void reportCurrentTime(){
    System.out.println ("Scheduling Tasks Examples: The time is now " + dateFormat ().format (new Date ()));
  }

  //每1分鐘執(zhí)行一次
  @Scheduled(cron = "0 */1 * * * * ")
  public void reportCurrentByCron(){
    System.out.println ("Scheduling Tasks Examples By Cron: The time is now " + dateFormat ().format (new Date ()));
  }

  private SimpleDateFormat dateFormat(){
    return new SimpleDateFormat ("HH:mm:ss");
  }
  
}

  <artifactId>quartz</artifactId>
  <version>1.8.4</version>
</dependency>

@Configuration
public class SchedledConfiguration {

  // 配置中設定了
  // ① targetMethod: 指定需要定時執(zhí)行scheduleInfoAction中的simpleJobTest()方法
  // ② concurrent：對于相同的JobDetail，當指定多個Trigger時, 很可能第一個job完成之前，
  // 第二個job就開始了。指定concurrent設為false，多個job不會并發(fā)運行，第二個job將不會在第一個job完成之前開始。
  // ③ cronExpression：0/10 * * * * ?表示每10秒執(zhí)行一次，具體可參考附表。
  // ④ triggers：通過再添加其他的ref元素可在list中放置多個觸發(fā)器。 scheduleInfoAction中的simpleJobTest()方法
