产生场景：

配置好quartz定时任务，调用报错。

产生原因：前台页面配置的jobGroup和jobName和数据库存储的不一致，导致报错，原因代码如下：

public void storeTrigger(OperableTrigger newTrigger, boolean replaceExisting) throws JobPersistenceException {
        TriggerWrapper tw = new TriggerWrapper((OperableTrigger)newTrigger.clone());
        synchronized(this.lock) {
            if (this.triggersByKey.get(tw.key) != null) {
                if (!replaceExisting) {
                    throw new ObjectAlreadyExistsException(newTrigger);
                }

                this.removeTrigger(newTrigger.getKey(), false);
            }

            if (this.retrieveJob(newTrigger.getJobKey()) == null) {
                throw new JobPersistenceException("The job (" + newTrigger.getJobKey() + ") referenced by the trigger does not exist.");
            } else {
                List jobList = (List)this.triggersByJob.get(tw.jobKey);
                if (jobList == null) {
                    jobList = new ArrayList(1);
                    this.triggersByJob.put(tw.jobKey, jobList);
                }

产生错误代码为：

throw new JobPersistenceException("The job (" + newTrigger.getJobKey() + ") referenced by the trigger does not exist.");

解决办法： 

由报错可知，错误出现在类RAMJobStore，找到对应代码，调试即可知道解决办法，jobGroup和jobName和数据库配置保持一致。

补充：

后来通过排查发现了问题的真正原因，理论上来说，这个定时任务会有一个前端页面显示数据库数据，基本不会出现数据不一致的情况。

通过实践，发现真正需要定时任务起作用，因为是在数据库直接添加的定时任务，真正生效还需要重启工程。
