Demo项目代码:
https://gitee.com/AnAnXiEr/activiti6-demo
数据模型设置
ACT_GE_* :通用数据表(GE表示General)
ACT_RE_* :流程定义存储表(RE表示Repository)
ACT_ID_* :身份信息表(ID表示Identity)
ACT_RU_* :运行是数据库表(RU表示Runtime)
ACT_HI_* :历史数据库表(HI表示History)
Mysql建表语句
在库org.activiti:activiti-engin:6.0.0下db目录
- 核心引擎 activiti.mysql.create.engin.sql(必须新建的)
- 历史数据 activiti.mysql.create.history.sql (可配置新增,也可不要历史数据)
- 身份信息 activiti.mysql.create.identity.sql (可配置新增,也可不要自带的用户信息)
通过配置文件配置
<!--是否使用historyUsed数据表、默认是true-->
<property name="dbHistoryUsed" value="false"></property>
<!--是否使用Identity数据表、默认是true-->
<property name="dbIdentityUsed" value="false"></property>

通用数据库
ACT_GE_PROPERTY :属性表(保存流程引擎的kv键值属性)
ACT_GE_BYTEARRAY :资源表(存储流程定义相关的资源)
act_ge_property表:
act_ge_property表
act_ge_byteArray表:
act_ge_byteArray表
