# 建表規則
# false 默認值。在啟動時會對比數據庫中保存的版本，如果沒有表或版本不匹配則拋出異常。生產環境常用
# true 對activiti所有表進行更新操作，不存在則自動創建。開發常用
# create_drop 在啟動時創建，在關閉時刪除（必須手動關閉引擎，才能刪除）。單元測試常用
# drop_create 在啟動時刪除原來的舊表，然后在創建新表（不需要手動關閉引擎）
database-schema-update: true
# 啟動的時候是否自動部署流程
check-process-definitions: false
# 歷史數據
# none 不保存任何的歷史數據，因此，在流程執行過程中，這是最高效的
# activity 級別高于none，保存流程實例與流程行為，其他數據不保存
# audit 除activity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history的默認值
# full 保存歷史數據的最高級別，除了會保存audit級別的數據外，還會保存其他全部流程相關的細節數據，包括一些流程參數等
history-level: audit
# 不生成歷史表 activiti6默認啟用,activiti7默認關閉
