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。
BPMN是由BPMI(The
Business Process Management Initiative)开发了一套标准叫业务流程建模符号(BPMN - Business Process Modeling Notation)BPMN定义了一个业务流程图(Business
Process Diagram),该业务流程图基于一个流程图(flowcharting),该流程图被设计用于创建业务流程操作的图形化模型。而一个业务流程模型(Business Process Model),指一个由的图形对象(graphical objects)组成的网状图,图形对象包括活动(acticities)和用于定义这些活动执行顺序的流程控制器(flow controls)。
以下是对Activiti框架几个常用功能的测试。
环境:mysql,eclipse,jdk1.7,activiti5.13
首先将Activiti相关的JAR包导入到项目中,由于JAR众多,这里就不列举了。主要记录代码部分。
Help ->
InstallNew Software,在如下Install界面板中,点击Add按钮
然后在Name和Location中分别填入如下内容:
Name: Activiti BPMN 2.0 designer
Location: http://activiti.org/designer/update/
然后一直下一步、下一步安装,根据提示重启eclipse
重启后,再打开菜单Windows->Preferences->Activiti->Save下流程流程图片的生成方式
