Question

我在Spring启动应用程序中使用Quartz。我需要设置一个触发器，它会在创建后立即触发，然后每隔30天触发一次。

所以，我创建了jobDetail

JobDetailFactoryBean jobDetailFactoryBean = new JobDetailFactoryBean();
        jobDetailFactoryBean.setJobClass(CheckContract.class);
        jobDetailFactoryBean.setName("JobDetail" + contract.getContractId());
        jobDetailFactoryBean.setGroup("timeoutJobDetail");
        jobDetailFactoryBean.setDescription("Job for timeout");
        jobDetailFactoryBean.setDurability(false);

        Map<String, Long> map = new HashMap<String, Long>();
        map.put("contractId", contract.getContractId());
        map.put("userId", user.getUserId());

        jobDetailFactoryBean.setJobDataAsMap(map);
        jobDetailFactoryBean.afterPropertiesSet();
        JobDetail jobDetail = jobDetailFactoryBean.getObject();

然后我创建触发器并将两者传递给调度程序

SimpleTriggerFactoryBean trigger = new SimpleTriggerFactoryBean();
                trigger.setName("checkContract" + contract.getContractId());
                trigger.setGroup("contractTriggers");
                trigger.setJobDetail(jobDetail);

                trigger.setStartTime(new Date());

                trigger.setRepeatInterval(30 * 24 * 60 * 60 *1000);
                trigger.afterPropertiesSet();
                scheduler.getScheduler().scheduleJob(jobDetail, trigger.getObject());

创建触发器后，我得到此异常

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: Repeat interval must be >= 0]

指向trigger.setRepeatInterval(30 * 24 * 60 * 60 *1000);

我真的不知道......

Answer 1

要构建区间构建器，请尝试使用CalendarIntervalScheduleBuilder

示例：

public Trigger get30DayTrigger(TriggerKey triggerKey, Date startTime) {
  CalendarIntervalScheduleBuilder intervalBuilder = CalendarIntervalScheduleBuilder
        .calendarIntervalSchedule()
        .withMisfireHandlingInstructionDoNothing();

  intervalBuilder.withIntervalInDays(30);

  TriggerBuilder<?> triggerBuilder = TriggerBuilder
        .newTrigger()
        .withIdentity(triggerKey)
        .withSchedule(intervalBuilder);

  if (startTime != null) {
    triggerBuilder.startAt(startTime);
  }

  return triggerBuilder.build()
}

然后你可以做类似

的事情

TriggerKey key = new TriggerKey("checkContract" + contract.getContractId(), "contractTriggers");
Trigger trigger = get30DayTrigger(key, new Date());

scheduler.getScheduler().scheduleJob(jobDetail, trigger);

Answer 2

30 * 24 * 60 * 60 * 1000 溢出整数限制。这就是你看到错误的原因。尝试执行类似下面的操作，将结果转换为long

trigger.setRepeatInterval(30L * 24 * 60 * 60 *1000);
