问题现象

由于工作流引擎不支持达梦数据库以及国产中间件，所以我们引入的时候会报错，这个时候就需要去改造代码和配置文件。各种文档和资料查找一天，现在对这个问题进行解决了。

解决方案

1.查看网上的各类教程，手动将源码复制粘贴出来，进行修改。这方面可以自行去查找对应文档
2.直接用一个改好的jar进行引入替换，就可以正常使用。

##可能出现的问题
1.当使用第一个时候，可能会出现jar的冲突
报当前错误

Parameter 0 of method transactionManager in org.activiti.spring.boot.JpaProc

这个时候解决方案
1.是升级版本，
2.去除关联引用
3.使用jar包

jar包提取链接
