动态修改Spring定时器的频率/时间

//String cronExpression = "0/"+String.valueOf(time)+" * * * * ?";

//System.out.println("=========修改定时器频率=========:"+cronExpression);

try {

trigger = (CronTrigger) birthdayMessageScheduler

.getTrigger("cronTrigger", Scheduler.DEFAULT_GROUP);

try {

trigger.setCronExpression(cronExpression);

birthdayMessageScheduler

.rescheduleJob("cronTrigger", Scheduler.DEFAULT_GROUP,

trigger);

} catch (java.text.ParseException e) {

throw new LmsBaseException("id", "失败！");

}

} catch (SchedulerException e) {
