如何解决CronTrigger没有在定义的时间执行
我有向用户发送每日电子邮件的时间表，我正在使用Crontrigger每天向用户发送电子邮件，但时间表在下午3:15时未执行。
public class Schedulars {
static Scheduler scheduler;
private static Logger LOG = Logger.getLogger(Schedulars.class);
public static Date date;
public static boolean flag = true;
public static boolean smscdownflag = true;
public static void schedular() {
try {
JobDetail dailyEmailJob = new JobDetail();
dailyEmailJob.setName("dailyEmailSchedular");
dailyEmailJob.setJobClass(SendDailyEmail.class);
scheduler = new StdSchedulerFactory().getScheduler();
scheduler.start();
CronTrigger dailyEmailJobTrigger = new CronTrigger();
dailyEmailJobTrigger.setName("dailyEmailJobTrigger");
try {
dailyEmailJobTrigger.setCronExpression("0 15 15 * * ?");
scheduler.scheduleJob(dailyEmailJob,dailyEmailJobTrigger);
} catch (ParseException e) {
LOG.error(e.getMessage(),e);
e.printStackTrace();
}
LOG.debug("------------------------------schedulars started----------------------");
} catch (SchedulerException e) {
e.printStackTrace();
LOG.error(e);
} finally {
}
}
public static Scheduler getScheduler() {
return scheduler;
}
public static void setScheduler(Scheduler scheduler) {
Schedulars.scheduler = scheduler;
}
}
发送必须在下午3点15分执行的每日电子邮件课程
public class SendDailyEmail implements Job {
private static Logger LOG = Logger.getLogger(SendDailyEmail.class);

Calendar calendar = Calendar.getInstance();
calendar.setTime(Schedulars.date);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
