SpringBoot集成Activiti案例

前言

Activiti项目是一项新的基于Apache许可的开源BPM平台，从基础开始构建，旨在提供支持新的BPMN 2.0标准，包括支持对象管理组（OMG），面对新技术的机遇，诸如互操作性和云架构，提供技术实现。

创始人Tom Baeyens是JBoss jBPM的项目架构师，以及另一位架构师Joram Barrez，一起加入到创建 Alfresco这项首次实现Apache开源许可的BPMN 2.0引擎开发中来。

Activiti是一个独立运作和经营的开源项目品牌，并将独立于Alfresco开源ECM系统运行。 Activiti将是一种轻量级，可嵌入的BPM引擎，而且还设计适用于可扩展的云架构。 Activiti将提供宽松的Apache许可2.0，以便这个项目可以广泛被使用，同时促进Activiti BPM引擎和BPMN 2.0的匹配，该项目现正由OMG通过标准审定。 加入Alfresco Activiti项目的是VMware的SpringSource分支，Alfresco的计划把该项目提交给Apache基础架构，希望吸引更多方面的BPM专家和促进BPM的创新。

代码实现

• 流程部署、查询流程定义
• 启动流程、查询流程
• 待办任务、完成任务
• 已结束流程、已完成任务
