现在可以动态添加了,但是问题是,比如设定任务5小时执行一次,但是动态添加上去之后不会立刻执行而是5小时之后在执行,目前我想让他 在添加的时候就执行一次,之后在5小时执行一次,求大佬帮助,我之前用配置文件的时候记得是可以设定的,但是用QuartzManager 管理类就不会设置了,求大佬
我的QuartzManager 类是这样的:
public class QuartzManager {
private static SchedulerFactory schedulerFactory = new StdSchedulerFactory();
/**
* @Description: 添加一个定时任务
*
* @param jobName 任务名
* @param jobGroupName 任务组名
* @param triggerName 触发器名
* @param triggerGroupName 触发器组名
* @param jobClass 任务
* @param cron 时间设置,参考quartz说明文档
*/
@SuppressWarnings({ "unchecked", "rawtypes" })
public static boolean addJob(String jobName, String jobGroupName, String triggerName, String triggerGroupName, Class jobClass, String cron,String group,String userId) {
try {
Scheduler sched = schedulerFactory.getScheduler();
// 任务名,任务组,任务执行类
JobDetail jobDetail= JobBuilder.newJob(jobClass).withIdentity(jobName, jobGroupName).build();
//用户的所属
jobDetail.getJobDataMap().put("groupId", group);
//用户的id
jobDetail.getJobDataMap().put("userId", userId);
// 触发器
TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger();
// 触发器名,触发器组
triggerBuilder.withIdentity(triggerName, triggerGroupName);
triggerBuilder.startNow();
// 触发器时间设定
triggerBuilder.withSchedule(CronScheduleBuilder.cronSchedule(cron));
// 创建Trigger对象
CronTrigger trigger = (CronTrigger) triggerBuilder.build();
// 调度容器设置JobDetail和Trigger
sched.scheduleJob(jobDetail, trigger);
// 启动
if (!sched.isShutdown()) {
sched.start();
}
return !sched.isShutdown();
} catch (Exception e) {
throw new RuntimeException(e);
}
}

CronTrigger trigger = (CronTrigger) sched.getTrigger(triggerKey);
if (trigger == null) {
System.out.println("未找到对应job");
return;
}
String oldTime = trigger.getCronExpression();

throw new RuntimeException(e);

添加任务的时候是通过控制器动态添加的,现在请问怎么设置添加的时候先执行一遍,而不是等时间到了在执行
