Spring + Quartz重新分配或更新触发器？

请尝试以下方法之一：

Trigger newTrigger = tb.withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(2)).build();

要么

Trigger newTrigger = tb.withSchedule(SimpleScheduleBuilder.repeatSecondlyForever(2)).build();

两者在语法上都是有效的。您的问题似乎

Trigger newTrigger =tb.withSchedule(simpleSchedule().withIntervalInSeconds(triggerInSec).build());
