activiti学习资料(xml格式的字符串发布流程)

Activiti发布

 jbpm4的开发成员tom离开了jboss后，加入afresco公司，并且才有activiti5的项目，这开源项目继承了jbpm4的所有优点，同时将其发扬光大，相对jbpm4，activiti5改进了储多我们国内开发人员关心的问题，如：

• 流程代办
• 在线流程设计器
• 流程嵌入式部署
• 流程独立部署
• 动流程节点
• 自由流程
• 支持了bpmn2的标准
• 支持规则引擎

     activiti 5 底层上的api跟jbpm4的api相似程序也达60%以上，特别是service提供的接口，都是在jbpm4上提供扩展，大大方便了jbpm4的开发人员，这也是tom的先明之处，毕竟jbpm原来打的品牌效应不可否认的，把原来的jbpm4积累的人气再次带至activiti5上，这也将是该项目能够断续前进的重要保障。

     尽管activiti5目前发展趋势前途光明，但其也有不足的地方，其前端的的表现总是存在不足，如在线流程设计器，目前eclipse插件生成的bpmn20.xml文件则不行，而官方提供的activiti-modler设计器，扩展及实现均面临困难，并且对浏览器的要求让它在国内的项目实施总会面临技术难度。

 

       宏天estbpm3则又是一个基于activiti5的产品，并且公司也有打算断续原来的产品销售模式，对企业开放源代码，而原来的设计器通过改进后，则可以直接支持activiti5的流程设计的需要，如：

 

 

设计器按设计器生成一份文档格式，通过系统中提供的xslt转化文档，完成转化后，生成bpmn20的格式文档，该文档可被activiti5直接识别。

 

其设计器及转化效果如下所示：

 

 

发布后，通过activiti5的api生成的流程图如下所示：

 

 

 

 

设计器原生成的文档格式：

转成后，则直接通过以下api可发布至流程引擎：

 

Deployment deployment= repositoryService.createDeployment().name(bpmDefinition.getSubject()).addString(bpmDefinition.getSubject()+".bpmn20.xml",actFlowDefXml).deploy();
