如上图在保存步骤中添加获取节点信息方法nodes();
方法如下:
//获取所有节点
JsonNode modelNode = new ObjectMapper().readTree(repositoryService.getModelEditorSource(model.getId()));
BpmnModel model1 = new BpmnJsonConverter().convertToBpmnModel(modelNode);
if(model1 != null) {
Process process = model1.getProcesses().get(0);//process对象封装了全部的节点、连线、以及关口等信息
Collection<FlowElement> flowElements = process.getFlowElements();//获得所有节点
for(FlowElement flowElement : flowElements) {
if(flowElement instanceof SequenceFlow){return;}//此处判断如果是“连线节点”,则跳过处理。
System.out.println("flowelement id:" + flowElement.getId() + " name:" + flowElement.getName() + " class:" + flowElement.getClass().toString());
if(flowElement instanceof EndEvent){//此处判断是否为结束节点,对应还有StartEvent开始节点
String idd = "";
List<SequenceFlow> alowList = ((org.activiti.bpmn.model.FlowNode) flowElement).getIncomingFlows();//获取入线信息-->获取所有上级节点
List<SequenceFlow> sequenceFlowList = ((org.activiti.bpmn.model.FlowNode) flowElement).getOutgoingFlows();//获取出线信息-->获取所有下级节点
for (SequenceFlow sequenceFlow : alowList) {//循环并可以获得所有上级节点id(父节点id),用于存储本地数据库
sequenceFlow.getSourceRef();//对应父节点和子节点的id
//其余属性可根据自己的需求来进行查看获取
}
