根據錯誤提示，解決方案如下

1. 打開項目連接的數據庫（我的是遠程服務器上的數據庫music）；
2. 打開數據表，找到錯誤提示中的QRTZ_CRON_TRIGGERS表；
   
   原表內容如下：
   
   再看一遍核心錯誤提示：
   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 = ?
   結合表的內容可知，SCHED_NAME列少了名爲mapScheduler、且TRIGGER_NAME爲syncTriggerBean的項！
3. 添加錯誤提示中的syncTriggerBean項（每個人定義的名稱不同），其中，CRON_EXPRESSION爲自定義的定時週期，和項目中定義的一致即可。
   
4. 重啓項目。
