java quartz2.2.1怎么更新trigger，我根据官网的例子测试 执行无效，没报错！

Question

TriggerKey triggerKey = TriggerKey.triggerKey("test", TRIGGERGROUP);
CronTrigger trigger = (CronTrigger) this.scheduler.getTrigger(triggerKey);

trigger.getTriggerBuilder().withIdentity(triggerKey)
.withSchedule(CronScheduleBuilder.cronSchedule("*/2 * * * * ?")).build();

this.scheduler.rescheduleJob(triggerKey, trigger);

我开始设置5s一次，现在用新的trigger替换旧的，为什么没效果？求指导
