springboot整合quartz实现定时任务示例

@Configuration
public class SchedledConfiguration {

  // 配置中设定了
  // ① targetMethod: 指定需要定时执行scheduleInfoAction中的simpleJobTest()方法
  // ② concurrent：对于相同的JobDetail，当指定多个Trigger时, 很可能第一个job完成之前，
  // 第二个job就开始了。指定concurrent设为false，多个job不会并发运行，第二个job将不会在第一个job完成之前开始。
  // ③ cronExpression：0/10 * * * * ?表示每10秒执行一次，具体可参考附表。
  // ④ triggers：通过再添加其他的ref元素可在list中放置多个触发器。 scheduleInfoAction中的simpleJobTest()方法
