SpringBoot+flowable-ui集成实战_flowable ui集成

前言

公司最近想要使用flowable作为我们工作流引擎，主要用于各类流程审批上。在网上搜索到了很多有参考意义的文章，但有些实现细节还需要自己去摸索。本文的实战包括：

1. 在项目中引入flowable的包可以使用flowable的api；
2. 将flowable-ui集成到自己项目里；
3. 如何使用flowable-ui创建的流程模型（我们用的是bpmn模型，所以后面的提到的流程都是指bpmn）；
4. 集成公司的用户认证体系；
5. 自动分配

flowable集成

flowable的集成有两部分：flowable-api与flowable-ui。flowable-api主要管创建好流程后怎么使用，flowable-ui就是通过页面去编排我们的流程。

jar包引入

这里的是较新的版本6.7.0。因为自身的框架用的是springboot，所以需要引入一个starter。引入的包里有flowable-ui-xxx是flowable-ui需要的包；其他是我们使用flowable-api需要的包。
