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
