# 达梦 flowable 适配
|
||||
|
||||
参考文档: [《Flowable6.8(6.x 版本通用)整合集成达梦 8 数据库(DM8)详解，解决自动生成表时 dmn 相关表语法报错问题》](https://blog.csdn.net/TangBoBoa/article/details/130392495)
|
||||
|
||||
## 1. 覆盖 flowable，liquibase 相关代码
|
||||
|
||||
把`flowable-patch/src`下的文件按文件结果添加到`yudao-server`项目对应目录中
|
||||
|
||||
## 2. 修改相关 DAO
|
||||
|
||||
例如`cn.iocoder.yudao.module.bpm.dal.dataobject.oa.BpmOALeaveDO`
|
||||
|
||||
```diff
|
||||
- @TableField("`type`")
|
||||
private String type;
|
||||
```
|
||||
|
||||
## 3. 关于`flowable.database-schema-update`配置
|
||||
|
||||
首次运行，修改`flowable.database-schema-update=true`，系统会自动建表，第二次运行需要修改为`false`。
|
||||
|
||||
## 4. TODO
|
||||
|
||||
配置`flowable.database-schema-update=true`第二次运行失败，报错
|
||||
|
||||

|
||||
