我使用石英调度程序自动运行进程。但它没有奏效。我按照以下步骤构建了该过程。
这是我的第一步，
BackUpModeOperator backUpModeOperator = new BackUpModeOperator();
backUpModeOperator.createBackUpMode();
BackUpMode backUpMode = backUpModeOperator.getBackUpMode(1);
Calendar c = Calendar.getInstance();
c.setTimeInMillis(System.currentTimeMillis());
int day_of_week = c.get(Calendar.DAY_OF_WEEK);
System.out.println("Day Of Week - " + day_of_week);
int HOUR = Calendar.getInstance().get(Calendar.HOUR_OF_DAY);
int MINUTE = Calendar.getInstance().get(Calendar.MINUTE);
AutoBackUp autoBackUp = new AutoBackUp();
if (backUpMode != null)
{
if (backUpMode.isMode() == true)
{
String day = backUpMode.getDay();
String[] split = day.split(",");
for (String split1 : split)
{
Integer dt = Integer.parseInt(split1);
System.out.println("dt - " + split1);
if (dt == day_of_week)
{
if (backUpMode.getBackUpTime() != null)
{
Time backUpTime = backUpMode.getBackUpTime();
String toString = backUpTime.toString();
String[] split2 = toString.split(":");
Integer hour = 0;
Integer minute = 0;
for (int j = 0; j < split2.length; j++)
{
hour = Integer.parseInt(split2[0]);
minute = Integer.parseInt(split2[1]);
}
if (HOUR == hour && MINUTE == minute)
{
try
{
autoBackUp.createAutoBackUp(HOUR, MINUTE);
} catch (SchedulerException ex)
{
ex.printStackTrace();
}
} else
{
}
}
break;
}
}
}
}
然后我构建了一个调度程序类，
AutoBackUp.java
import java.util.Date;
import static org.quartz.DateBuilder.todayAt;
import static org.quartz.DateBuilder.tomorrowAt;
import static org.quartz.JobBuilder.newJob;
import org.quartz.JobDetail;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import static org.quartz.SimpleScheduleBuilder.simpleSchedule;
import org.quartz.Trigger;
import static org.quartz.TriggerBuilder.newTrigger;
import org.quartz.TriggerKey;
import org.quartz.impl.StdSchedulerFactory;
public class AutoBackUp
{
Scheduler scheduler;
int dayHour;
int dayMinute;
public void createAutoBackUp(int hour, int minute) throws SchedulerException
{
scheduler = new StdSchedulerFactory().getScheduler();
JobKey backUpJobKey = new JobKey("backUpJob", "backUpGroup");
TriggerKey backUpTriggerKey = new TriggerKey("backUpTrigger", "backUpTriggerGroup");
boolean checkExists = scheduler.checkExists(backUpJobKey);
dayHour = hour;
dayMinute = minute;
scheduleJob(AutoBackupCreator.class, checkExists, backUpJobKey, backUpTriggerKey, dayHour, dayMinute);
}
private void scheduleJob(Class c, boolean checkExists, JobKey jobKey, TriggerKey triggerKey, int day_hour, int day_minute)
{
System.out.println("Print First Line");
JobDetail jobDetail = null;
if (c.isInstance(new AutoBackupCreator()))
{
System.out.println("Print Second Line");
jobDetail = newJob(AutoBackupCreator.class).withIdentity(jobKey).build();
}
System.out.println("Print Third Line");
Date providedDate = todayAt(day_hour, day_minute, 0);
Date currentDate = new Date();
System.out.println("Print Fourth Line");
if (currentDate.before(providedDate))
{
System.out.println("todayAt() can be perfomed");
} else
{
System.out.println("tomorrowAt() can be perfomed");
}
Trigger trigger = newTrigger().withIdentity(triggerKey)
.withSchedule(simpleSchedule().withIntervalInHours(24).repeatForever())
.startAt(currentDate.before(providedDate) ? (todayAt(day_hour, day_minute, 0)) : (tomorrowAt(day_hour, day_minute, 0))).build();
try
{
if (checkExists)
{
scheduler.start();
scheduler.rescheduleJob(triggerKey, trigger);
System.out.println("Job Re-scheduled");
} else
{
scheduler.start();
scheduler.scheduleJob(jobDetail, trigger);
System.out.println("Job Scheduled");
}
} catch (SchedulerException ex)
{
ex.printStackTrace();
}
}
}
此自动任务基于预先保存的时间。

这总是触发tomorrowAt()，但我想触发今天（）。
对此有任何想法。
谢谢。
