flowable流程结束触发监听器 | flowable流程结束获取结束节点 | flowable流程结束事件响应监听器

下面代码是该监听器是对每个到达结束事件后执行的。

原本的流程定义是如果其中任意某个节点进行了驳回，则直接结束流程。

所以在每个节点的驳回对应的排他网关都设置了EndEvent

百度关于该问题答案出来的几乎清一色全是同一个答案，给了三种方法，但是每个方法的代码都有他自定义的部分，是不完整的东西。
下面是网上找的东西，里面的flowableService是这个比玩意自定义的。

下面这段代码是被转载多次的代码，它监听的是指向结束事件的上一个节点。
也就是他的当前节点可能是最后一岗。
然后最后一岗—>EndEvent

@Component
public class ProcessEndListener implements FlowableEventListener {@AutowiredFlowableService flowableService;@Overridepublic void onEvent(FlowableEvent event) {// 当前节点任务实体,TaskEntity taskEntity = (TaskEntity) ((FlowableEntityEventImpl) event).getEntity();String taskId = taskEntity.getId();String curActId = flowableService.getNodeId(taskId);String procDefId = ProcUtils.getProcessDefinitionByTaskId(taskEntity.getId()).getId();Process process = ProcessDefinitionUtil.getProcess(procDefId);//遍历整个process,找到endEventId是什么，与当前taskId作对比List<FlowElement> flowElements = (List<FlowElement>) process.getFlowElements();for (FlowElement flowElement : flowElements) {if (flowElement instanceof SequenceFlow) {SequenceFlow flow = (SequenceFlow) flowElement;FlowElement sourceFlowElement = flow.getSourceFlowElement();FlowElement targetFlowElement = flow.getTargetFlowElement();//如果当前边的下一个节点是endEvent，那么获取当前边if(targetFlowElement instanceof EndEvent && sourceFlowElement.getId().equals(curActId)){System.out.println("下一个是结束节点！！");}}}}@Overridepublic boolean isFailOnException() {return false;}@Overridepublic boolean isFireOnTransactionLifecycleEvent() {return false;}@Overridepublic String getOnTransaction() {return null;}
}

用我上面的代码实现示例这个b的代码

    @Overridepublic void onEvent(FlowableEvent event) {log.info("ProcessEndListener:{}", JSON.toJSONString(event.getType()));TaskService taskService = SpringUtil.getBean(TaskService.class);RuntimeService runtimeService = SpringUtil.getBean(RuntimeService.class);FlowableEntityEventImpl flowableEntityEvent = ((FlowableEntityEventImpl) event);ProcessInstance pi = (ProcessInstance) flowableEntityEvent.getEntity();List<Task> tasks = taskService.createTaskQuery().active().processInstanceId(pi.getId()).list();Task t = tasks.get(0);String bizKey = pi.getBusinessKey();log.info("ProcessEndListener#bizKey:{}", bizKey);String procDefId = pi.getProcessDefinitionId();List<Execution> exes = runtimeService.createExecutionQuery().processInstanceId(pi.getProcessInstanceId()).processDefinitionId(procDefId).executionId(t.getExecutionId()).list();String curActId = exes.get(0).getActivityId();BpmnModel bm = ProcessDefinitionUtil.getBpmnModel(t.getProcessDefinitionId());FlowNode flowNode = (FlowNode) bm.getFlowElement(curActId);//如果当前节点是最后一岗List<SequenceFlow> outFlows = flowNode.getOutgoingFlows(); //此处需要获取他的下一个节点是否为EndEventfor (SequenceFlow sequenceFlow : outFlows) { //遍历outFlowssequenceFlow.getTargetFlowElement();//用该flow节点与EndEvent进行对比判断，也就是当前节点的下一个节点和EndEvent判断是否一致，是则说明当前节点就是最后一岗，且它的下一个节点就是结束事件}}
