springCloud maven 多模块项目，在idea中集成activiti工作流项目。
springCloud项目以RuoYI 项目为基础搭建：https://gitee.com/y_project/RuoYi-Cloud
activiti工作流项目参照：https://gitee.com/calvinhwang123/RuoYi-Process
首先在springcloud 项目中创建子模块：activiti，可以不选任何的依赖包。
将RuoYi-Process中的后端代码复制到activiti子模块中，解决好各种依赖和冲突。
由于activiti模块需要作为单独的项目启动，因此添加网关依赖，数据库连接依赖，公共依赖，activiti的依赖等：

<!-- SpringBoot集成thymeleaf模板 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency>
由于前端用到了thymeleaf，需要添加thymeleaf依赖。
解决好各种冲突依赖后，项目可以尝试启动了。
