#1.false,默認值,acticiti啟動時對比數據庫表中保存的版本，如果沒有表或者版本不匹配，將拋出異常
#2.true,acticiti會對數據中所有的表進行更新操作，如果表不存在，則自動創建
#3.create_drop,在acticiti啟動時創建表，關閉時刪除表（必須手動關閉引擎才能刪除表）
#4.drop_create,在acticiti啟動時刪除原來的表，然後創建新表（不需要手動關閉引擎）
spring.activiti.database-schema-update=true
#檢測歷史表是否存在，acticit7默認沒有開啟歷史記錄信息
spring.activiti.db-history-used=true
#歷史記錄等級
#1.none:不保存任何歷史記錄，因此在流程執行過程中，這是最高效的
#2.acticiti:級別高於none,保存流程實例與流程行為，其他數據不保存
#3.audit：除activiti級別會保存的數據外，還會保存全部的流程任務及其屬性，audit為默認值
#4.full:保存歷史數據的最高級別，除瞭保存audit級別的數據外，還會保存其他流程相關的細節數據，包括一些流程參數等
spring.activiti.history-level=full
#默認true,效驗流程文件，默認效驗resources下的processes文件夾裡的流程，為true自動部署流程，為false則不部署
#spring.activiti.check-process-definitions=false
