做个简单记录，以后写文章详解
// 获取当前节点的activityId,即xml中每个标签的ID
String currentActivityId = execution.getCurrentActivityId();
List<Task> list1 = taskService.createTaskQuery().processInstanceId(processInstance.getProcessInstanceId()).list();
// taskService.addComment(currentTask.getId(), execution.getProcessInstanceId(), body.get("msg").toString());
BpmnModel bpmnModel = repositoryService.getBpmnModel(execution.getProcessDefinitionId());
FlowNode flowNode = (FlowNode)bpmnModel.getFlowElement(currentActivityId);
SequenceFlow sequenceFlow = flowNode.getIncomingFlows().get(0);
// 获取上一个节点的activityId
String sourceRef = sequenceFlow.getSourceRef();
// 流程回退到上一个节点，审批人继续审批
runtimeService.createChangeActivityStateBuilder().processInstanceId(processInstance.getProcessInstanceId())
.moveActivityIdTo(currentActivityId,sourceRef).changeState();免责声明：本站发布的内容（图片、视频和文字）以原创、转载和分享为主，文章观点不代表本网站立场，如果涉及侵权请联系站长邮箱：is@yisu.com进行举报，并提供相关证据，一经查实，将立刻删除涉嫌侵权内容。
