如何對quartz定時任務設置結束時間

這篇文章主要介紹了如何對quartz定時任務設置結束時間問題,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教

quartz定時任務設置結束時間

在使用quartz時，使用cornTrigger再設置一個結束時間 endAt（“結束的時間”），實現(xiàn)在任務執(zhí)后自動銷毀任務，在到了結束時間之后，job并不會留在內(nèi)存中，job是直接被delete掉，所以不擔心會有內(nèi)存滿的情況;

代碼：

//按新的cronExpression表達式構建一個新的trigger
trigger = TriggerBuilder.newTrigger()
        .withIdentity(triggerName, triggerGroupName)
        .withSchedule(scheduleBuilder)
        .endAt(endDate)
        .build();

附屬上查詢所有job代碼：

/**
 * 查詢所有的job
 */
public static void getAllJobs(){
    try {
        Scheduler scheduler = sf.getScheduler();
        for (String groupName : scheduler.getJobGroupNames()) {
            for (JobKey jobKey : scheduler.getJobKeys(GroupMatcher.jobGroupEquals(groupName))) {
                String jobName = jobKey.getName();
                String jobGroup = jobKey.getGroup();
                //get job's trigger
                List<Trigger> triggers = (List<Trigger>) scheduler.getTriggersOfJob(jobKey);
                Date nextFireTime = triggers.get(0).getNextFireTime();
                System.out.println("[jobName] : " + jobName + " [groupName] : "
                        + jobGroup + " - " + nextFireTime);
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
