一、錯誤主題：
2020-02-07 22:37:43.596 ERROR 12612 --- [ scheduling-1] o.s.s.s.TaskUtils$LoggingErrorHandler : Unexpected error occurred in scheduled task
org.springframework.jdbc.BadSqlGrammarException:

### The error may involve cn.changemax.dao.FilmInfoDAO.batchUpdate-Inline

二、筆者發現什么代碼也沒改，突然sql執行錯誤了。還報語法錯誤，關鍵我還把這個sql拿去數據庫中執行了，反而執行成功了。
思慮再三發現：是在配置文件中關閉了一次執行多條sql的配置。
改為如下：
url: jdbc:mysql://127.0.0.1:3306/xxxxxxxxxxxx?useSSL=false&useUnicode=true&characterEncoding=utf-8&autoReconnect=true&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
核心在於參數：allowMultiQueries=true
