Activiti的流程定义文件可以直接部署bpmn20.xml、zip、bar文件,其中后面的zip和bar类型一样都是压缩文件格式,bpmn20.xml是符合bpmn2.0规范的xml定义。 今天要解决的问题就是帮助大家打包流程资源文件,其中肯能包括:bpmn20.xml、png、form等文件。
大多数开发人员都是用Activiti Designer来设计流程定义,可能业务人员使用了其他的流程设计器来描述业务,然后开发人员用Activiti Designer来“深加工”以便让计算机能读懂流程的走向及其逻辑。
如何打包是最近“Activiti中文”群里问的比较多的问题之一,因为太忙没用时间一一说明,这也是因为目前的5.9版本设计器导致的,主要是在5.9版本之前设计器会自动生成一个bpmn20.xml文件,而5.9版本中不再使用之前的.activiti文件,直接把设计与最终的流程定义文件合并为一个bpmn文件。具体的说明请参考《从Activiti Designer5.8升级到5.9遇到的问题》。
下面我们以kft-activiti-demo项目中的请假流程为例介绍如何打包,项目结构如下图。
看了刚刚提到的文章应该明白leave.bpmn和在5.8版本中生成的bpmn20.xml一样,所以可以直接把leave.bpmn复制一份改名为leave.bpmn20.xml,然后手动把leave.bpmn20.xml和leave.png用压缩工具打包成leave.zip即可。
用ant脚本无非就是代替手动操作让工具自动根据配置打包,我在kft-activiti-demo(master分支)项目中添加了此功能,把里面的代码拿出来分享给大家。

如果有外部form文件也可以加入到zip包中。
bar文件就是zip格式的,仅仅是扩展名不同而已,所以打包bar文件直接用上面的方式,只不过把扩展名zip更好成bar就可以了。
如何打包Bar我就不多说了,官网的手册已经说的很详细了,请移步:http://www.activiti.org/userguide/index.html#eclipseDesignerBPMNFeatures,找到Activiti Designer deployment features有详细的说明。
