Задача не может быть выполнена. После того, как я использую текучий API для динамического изменения процесса, но когда я перезапускаю сервис, я могу снова выполнить задачу. Определение процесса развернуто, экземпляр процесса инициирован, а проверка не завершена. В это время определение процесса изменяется, исходная задача не может быть рассмотрена, но после перезапуска службы можно просмотреть исходную задачу. Вот код для динамического изменения процесса:
public void modifyProcessReplaceALUserTask(ModifyProcessParam param) {
ProcessDefinition processDefinition = reposi`enter code here`toryService.createProcessDefinitionQuery()
.processDefinitionKey(param.getKey())
.latestVersion()
.singleResult();
if (Objects.isNull(processDefinition)) {
throw new RuntimeException("cannot find processDefinition");
}
BpmnModel bpmnModel = repositoryService.getBpmnModel(processDefinition.getId());
Process mainProcess = bpmnModel.getMainProcess();
StartEvent startEvent = mainProcess.findFlowElementsOfType(StartEvent.class).get(0);
EndEvent endEvent = mainProcess.findFlowElementsOfType(EndEvent.class).get(0);
List<FlowNode> nodes = param.getNodes();
if (CollectionUtils.isEmpty(nodes)) {
throw new RuntimeException("nodes is empty");
}
//delete
List<UserTask> flowElementsOfType = mainProcess.findFlowElementsOfType(UserTask.class, false);
for (UserTask userTask : flowElementsOfType) {
List<SequenceFlow> outgoingFlows = userTask.getOutgoingFlows();
for (SequenceFlow outgoingFlow : outgoingFlows) {
mainProcess.removeFlowElement(outgoingFlow.getId());
}
mainProcess.removeFlowElement(userTask.getId());
}
//add
String sourceId = startEvent.getId();
String targetId = endEvent.getId();
for (int i = 0; i < nodes.size(); i++) {
FlowNode node = nodes.get(i);
UserTask newUserTask = CreateBpmnUtil.createUserTask(node.getId(), node.getName(), node.getCandidateUsers());
mainProcess.addFlowElement(newUserTask);
if (i == 0) {
List<SequenceFlow> outgoingFlows = startEvent.getOutgoingFlows();
for (SequenceFlow outgoingFlow : outgoingFlows) {
outgoingFlow.setTargetRef(newUserTask.getId());
}
sourceId = newUserTask.getId();
continue;
}
SequenceFlow pass = CreateBpmnUtil.createSequenceFlow(sourceId, newUserTask.getId(), "pass", "${operation==1}");
SequenceFlow notPass = CreateBpmnUtil.createSequenceFlow(sourceId, targetId, "reject", "${operation==-1}");
mainProcess.addFlowElement(pass);
mainProcess.addFlowElement(notPass);
sourceId = newUserTask.getId();
}
mainProcess.addFlowElement(CreateBpmnUtil.createSequenceFlow(sourceId, targetId, "pass", "${operation==1}"));
mainProcess.addFlowElement(CreateBpmnUtil.createSequenceFlow(sourceId, targetId, "reject", "${operation==-1}"));
new BpmnAutoLayout(bpmnModel).execute();
Deployment deployment = repositoryService.createDeployment()
.addBpmnModel(param.getKey() + ".bpmn", bpmnModel)
.name(param.getKey() + "_deployment").deploy();
log.info("finish:{}", deployment.getId());
}
информация об ошибке:

Check the execution id that is being passed (it should not be a process instance execution, but a child execution currently referencing a flow element).
