SpringBoot集合工作流(WorkFlow)Flowable

在我不久前做的一个项目中，需要完成一个审批模块，选用了flowable。

以下就是flowable简单的使用流程介绍

流程

一，引入依赖

<!--flowable依赖-->
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter</artifactId>
            <version>6.7.2</version>
        </dependency>

二，创建流程图

此处使用到了IDEA的一个插件 Flowable BPMN visualizer

创建bpmn20.xml文件

 

利用插件绘制流程图

右键点击bpmn20.xml文件

绘制流程图

右键选择自己所需

绘制完成之后，bpmn20.xml文件内容就会自己生成了Wow Amazing! ! !

Controller
