项目启动时Quartz定时任务报错（已解决）

项目启动后，报如下错误

根据错误提示，解决方案如下

1. 打开项目连接的数据库（我的是远程服务器上的数据库music）；
2. 打开数据表，找到错误提示中的QRTZ_CRON_TRIGGERS表；
   
   原表内容如下：
   
   再看一遍核心错误提示：
   No record found for selection of Trigger with key: ‘DEFAULT.syncTriggerBean’ and statement: SELECT * FROM QRTZ_CRON_TRIGGERS WHERE SCHED_NAME = ‘mapScheduler’ AND TRIGGER_NAME = ? AND TRIGGER_GROUP = ?
   结合表的内容可知，SCHED_NAME列少了名为mapScheduler、且TRIGGER_NAME为syncTriggerBean的项！
3. 添加错误提示中的syncTriggerBean项（每个人定义的名称不同），其中，CRON_EXPRESSION为自定义的定时周期，和项目中定义的一致即可。
   
4. 重启项目。
