我正在考虑使用Quartz安排我的应用程序，但在所有情况下，作业触发器似乎是一次性活动，并且对触发器的更改需要重新启动应用程序-seployed生效。 有没有办法可以让工作触发检查工作时间表的更改，而无需重新部署代码？ 谢谢，
I'm looking into scheduling my application with Quartz, but in all cases, the job trigger seems to be a one-time activity, and changes to the trigger need the application to be re-deployed to take effect. Is there any way I can have the job trigger check for changes to the job schedule without having to redeploy the code? Thanks,
推荐答案
再次安排作业，使用新触发器。
Schedule the job again, using the new trigger. public static <T> T scheduleCronJob(Class<T> clazz, String cronString, String uid){ try{ if(cronString == null){ throw new CronStringConfigurationException(); } String jobGroupName = "cronJobsGroup"; String jobName = "cronJob" + uid; String triggerGroupName = "cronTriggers"; String triggerName = "triggerFor" + uid; JobDetail jobDetail = new JobDetail(jobName, jobGroupName, clazz); CronTrigger trigger = new CronTrigger( triggerName, triggerGroupName, jobName, jobGroupName, cronString); JobDataMap jobDataMap = new JobDataMap(); jobDetail.setJobDataMap(jobDataMap); getScheduler().scheduleJob(jobDetail, trigger); } catch(Exception e){ // print error message, throw stack trace } return null; } public static void reloadCronJob(Class clazz, String cronString, String uid) throws SystemException, ParseException, SchedulerException, CronStringConfigurationException, PortalException{ // locate the job String jobGroupName = "cronJobs"; String jobName = "jobFor" + uid; if(cronString == null){ throw new CronStringConfigurationException(); } JobDetail jobDetail = null; Class<?> jobClass = null; // remove the old job/trigger if it exists try{ jobDetail = scheduler.getJobDetail(jobName, jobGroupName); if(jobDetail != null){ jobClass = jobDetail.getJobClass(); } scheduler.deleteJob(jobName, jobGroupName); } catch(Exception e){ e.printStackTrace(); } if(jobClass == null){ jobClass = clazz; } // create a new trigger scheduleCronJob(jobClass, expandoColumnName, uid); System.out.println("(re)scheduled job " + jobName + " using new cron string " + cronString); }
