看到有些流程图采用仿钉钉的流程设计,比如下面界面:
这种方式虽然简单,但可能符合中国人的习惯,使用简单直观,所以也有一定的市场。
如何结合现有的bpmn-process-designer流程设计器进行兼容是需要考虑的问题。
现有流程设计器采用标准的bpmn规范,生成xml文件。
而一般仿钉钉的流程图是生成相应的json,所以需要进行流程图转换,以便兼容。
基本思路;
1、仿钉钉做的流程图,也可以跟bpmn-process-designer流程设计器类似,可以查看flowable的json格式或xml格式,这个就需要进行转换。
2、主要通过flowable的相关类与方法,把json格式转换成xml格式,同时这个xml文件可以导入到bpmn-process-designer流程设计器进行查看与验证,这样后面的流程逻辑都不需要修改。
3、可以主要通过BpmnModel,SequenceFlow,Process,StartEvent,EndEvent,FlowableListener,BpmnAutoLayout,BpmnXMLConverter等flowable类或方法来实现从json转换成xml文件。
4、前端参考网上一些开源项目,但form表单还是采用现有的formdesigner,同时也是考虑支持节点的表单支持
5、也要考虑自定义业务表单的支持
6、先支持简单的并行,条件等流程节点的支持,后续再支持复杂的流程设计。
下面附上一个标注的flowable的xml流程文件

后续根据上面的思路实现前后端代码。
