Flowable是什么下面是官方文档介绍 Flowable是一个使用Java编写的轻量级业务流程引擎。Flowable流程引擎可用于部署BPMN 2.0流程定义用于定义流程的行业XML标准 创建这些流程定义的流程实例进行查询访问运行中或历史的流程实例与相关数据等等。这个章节将用一个可以在你自己的开发环境中使用的例子逐步介绍各种概念与API。 说人话无论是学生还是职场员工都用过OA系统其中的请假流程大家应该都用过一般是发起请假-辅导员审批-院长审批类似这样的流程。如果自己去实现这种功能的话我个人的想法是使用状态机模式每个过程如何流转都需要自己去实现比较麻烦。 而Flowable框架帮我解决了这个麻烦只需要我们遵循BPMN 2.0可以理解为一种流程规范就可以帮我们自动完成。而且它提供了图形化页面只需要使用拖拽的方式就可以完成流程的定义我们只用关注业务逻辑即可。
快速开始
我们先用JavaSE简单体验一下下面会带大家集成SpringBoot和使用图形化界面。 本节例子为发起请求-经理审批审批通过则结束不通过则发送失败邮件。

使用Flowable-ui图形化界面
下载Flowable和Tomcat
Flowable网址http://www.flowable.org/downloads.html Tomcat网址http://tomcat.apache.org/
部署
将Flowable的war包放到Tomcat的webapps目录下然后启动Tomcat 访问http://localhost:8080/flowable-ui默认用户名和密码为 admin / test
绘制 我们此节和下一节用的例子比之前多一个环节由组长和经理两个人审核。
使用建模器绘制绘制后点击导出生成xml文件。
