#1.false,默认值,acticiti启动时对比数据库表中保存的版本，如果没有表或者版本不匹配，将抛出异常
#2.true,acticiti会对数据中所有的表进行更新操作，如果表不存在，则自动创建
#3.create_drop,在acticiti启动时创建表，关闭时删除表（必须手动关闭引擎才能删除表）
#4.drop_create,在acticiti启动时删除原来的表，然后创建新表（不需要手动关闭引擎）
spring.activiti.database-schema-update=true
#检测历史表是否存在，acticit7默认没有开启历史记录信息
spring.activiti.db-history-used=true
#历史记录等级
#1.none:不保存任何历史记录，因此在流程执行过程中，这是最高效的
#2.acticiti:级别高于none,保存流程实例与流程行为，其他数据不保存
#3.audit：除activiti级别会保存的数据外，还会保存全部的流程任务及其属性，audit为默认值
#4.full:保存历史数据的最高级别，除了保存audit级别的数据外，还会保存其他流程相关的细节数据，包括一些流程参数等
spring.activiti.history-level=full
#默认true,效验流程文件，默认效验resources下的processes文件夹里的流程，为true自动部署流程，为false则不部署
