flowable 流程动态设置监听器(非xml中定义)及发起时从驳回节点开始审批实现
一、flowable 使用代码动态修改监听器
1、配置类
@Configuration public class FlowableGlobListenerConfig { @Lazy @Autowired private TaskStartListener taskStartListener; @Lazy @Autowired private TaskCompleteListener taskCompletedListener; @Lazy @Autowired private ActivityCompletedListener activityCompletedListener; @Bean @Primary public EngineConfigurationConfigurer<SpringProcessEngineConfiguration> globalListenerConfigurer() { return engineConfiguration -> engineConfiguration.setTypedEventListeners(this.customFlowableListeners()); } /** * 监听类配置 flowable监听器级别 * * @return java.util.Map<java.lang.String, java.util.List < org.flowable.common.engine.api.delegate.event.FlowableEventListener>> */ private Map<String, List<FlowableEventListener>> customFlowableListeners() { Map<String, List<FlowableEventListener>> listenerMap = Maps.newHashMap(); listenerMap.put(FlowableEngineEventType.TASK_CREATED.name(), new ArrayList<>(Collections.singletonList(taskStartListener))); listenerMap.put(FlowableEngineEventType.TASK_COMPLETED.name(), new ArrayList<>(Collections.singletonList(taskCompletedListener))); listenerMap.put(FlowableEngineEventType.ACTIVITY_COMPLETED.name(), new ArrayList<>(Collections.singletonList(activityCompletedListener))); return listenerMap; } }
说明:通过注册关注的事件,实现对应的监听逻辑实现相应业务逻辑

3、流程节点结束时逻辑
import cn.as.maple.process.TaskComplateInvoker; import cn.as.maple.process.api.util.SpringContextUtil; import java.util.Map; import org.flowable.common.engine.api.delegate.event.FlowableEvent; import org.flowable.common.engine.api.delegate.event.FlowableEventListener; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Component; @Component("taskCompleteListener") public class TaskCompleteListener implements FlowableEventListener { private static final Logger log = LoggerFactory.getLogger(TaskCompleteListener.class); public TaskCompleteListener() { } public void onEvent(FlowableEvent event) { Map<String, TaskComplateInvoker> type = SpringContextUtil.getBeansOfType(TaskComplateInvoker.class); type.values().parallelStream().forEach( (invoker) -> { invoker.consume(event); } ); } public boolean isFailOnException() { return false; } public boolean isFireOnTransactionLifecycleEvent() { return false; } public String getOnTransaction() { return null; } }
4、流程任意节点结束时
@Slf4j @Component("activityCompletedListener") public class ActivityCompletedListener implements FlowableEventListener { @Autowired private RepositoryService repositoryService; @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Autowired private HistoryService historyService; @Autowired private ApplicationEventPublisher applicationEventPublisher; @Override public void onEvent(FlowableEvent event) { if(event instanceof FlowableActivityEventImpl) { FlowableActivityEventImpl activityEvent = (FlowableActivityEventImpl) event; String activityType = activityEvent.getActivityType(); if(!"userTask".equals(activityType)) { return; } String processDefinitionId = activityEvent.getProcessDefinitionId(); String processInstanceId = activityEvent.getProcessInstanceId(); ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId(processInstanceId).singleResult(); ProcessDefinition processDefinition = repositoryService.getProcessDefinition(processDefinitionId); List<HistoricActivityInstance> allProcessNodes = historyService.createHistoricActivityInstanceQuery() .activityId(processInstance.getActivityId()) .processInstanceId(processInstanceId) .list(); List<HistoricActivityInstance> userTaskList = allProcessNodes.stream().filter(e -> e.getActivityType().equals("userTask")).collect(Collectors.toList()); //判断节点列表中是否大于两个节点、第一个必为填报节点、第二个必为审批节点 String businessKey = processInstance.getBusinessKey(); if(userTaskList.size() >= 2) { ListenerEvent listenerEvent = new ListenerEvent(); listenerEvent.setApprovalResults("PROGRESS_IN"); listenerEvent.setBusinessKey(businessKey); listenerEvent.setDefinitionId(processDefinitionId); listenerEvent.setProcessInstanceId(processInstanceId); listenerEvent.setDefinitionKey(processDefinition.getKey()); listenerEvent.setDefinitionName(processDefinition.getName()); this.applicationEventPublisher.publishEvent(new ListenerEventSource(listenerEvent)); } } } @Override public boolean isFailOnException() { return false; } @Override public boolean isFireOnTransactionLifecycleEvent() { return false; } @Override public String getOnTransaction() { return null; } }
二、流程跳过逻辑
/** * 对已驳回的流程发起时选择从驳回节点开始审批 * @param oldInstId * @param newInstId */ public void skipPreAgreeNodes(String oldInstId, String newInstId){ HistoricProcessInstance processInstance = historyService.createHistoricProcessInstanceQuery().processInstanceId(oldInstId).singleResult(); String deployId = Optional.ofNullable(processInstance) .map(HistoricProcessInstance::getProcessDefinitionId) .map(item -> item.substring(item.lastIndexOf(":") + 1)) .orElse(null); Map<String, Object> record = this.flowTaskService.flowRecord(oldInstId, deployId); List<FlowTask> flowList = (List<FlowTask>) record.getOrDefault("flowList", Lists.newArrayList()); if(flowList.size()<2) { return; } FlowTask flowTask = flowList.get(0); String rejectTaskKey = flowTask.getTaskDefKey(); List<FlowTask> agrees = flowList.stream().skip(1).limit(flowList.size() - 2).collect(Collectors.toList()); List<String> allNodes = agrees.stream() .map(FlowTask::getTaskDefKey) .distinct().collect(Collectors.toList()); for(String taskDefKey : allNodes) { List<Task> list = taskService.createTaskQuery().processInstanceId(newInstId).list(); if(list.stream().anyMatch(e->rejectTaskKey.equals(e.getTaskDefinitionKey()))) { if(agrees.stream().noneMatch(e->rejectTaskKey.equals(e.getTaskDefKey()))) { break; } } for(Task task : list) { //筛选办理记录中节点定义id与当前id一致的记录 List<FlowTask> allTasks = agrees.stream() .filter(e -> e.getTaskDefKey().equals(task.getTaskDefinitionKey())) .collect(Collectors.toList()); String assignee = task.getAssignee(); boolean preJb = false; for(int i = allTasks.size()-1; i >-1 ; i--) { FlowTask curTask = allTasks.get(i); String curAssignee = curTask.getAssigneeId(); FlowComment comment = curTask.getComment(); String rjAssignee = flowTask.getAssigneeId(); boolean willJb = comment.getType().equals("11"); FlowTaskVo add = new FlowTaskVo(); if(willJb && allTasks.size() == 1) { add.setTaskId(task.getId()); add.setInstanceId(newInstId); add.setUserId(curAssignee); add.setAcceptUserId(rjAssignee); add.setComment(comment.getComment()); flowTaskService.beforeAddSign(add); break; } String nextAssignee = i-1<0? rjAssignee: allTasks.get(i - 1).getAssigneeId(); //下一个也是加办、说明当前加办的基础上有有新的加办且当前加办未审核 boolean nextJb = i - 1 >= 0 && allTasks.get(i - 1).getComment().getType().equals("11"); if(!willJb) { //多实例节点时assignee不可能为空,需根据审批记录中的审批人id 判断需不需要跳过该用户 if(assignee !=null && !assignee.equals(curAssignee)) { continue; } } else { add.setTaskId(task.getId()); add.setInstanceId(newInstId); add.setUserId(curAssignee); add.setAcceptUserId(nextAssignee); add.setComment(comment.getComment()); flowTaskService.beforeAddSign(add); if(nextJb) { continue; } } if(preJb) { preJb = false; continue; } FlowTaskVo flowTaskVo = new FlowTaskVo(); BeanUtils.copyProperties(task, flowTaskVo); flowTaskVo.setInstanceId(newInstId); flowTaskVo.setComment(comment.getComment()); flowTaskVo.setAssignee(willJb? nextAssignee : curAssignee); flowTaskVo.setUserId(willJb? nextAssignee : curAssignee); flowTaskVo.setTaskId(task.getId()); List<Attachment> attachmentList = curTask.getAttachmentList(); if(CollUtil.isNotEmpty(attachmentList)) { List<MultipartFile> files = attachmentList.stream().map(f -> { InputStream attachmentContent = taskService.getAttachmentContent(f.getId()); try { return new MockMultipartFile(f.getName(), f.getName(), f.getType(), attachmentContent); } catch(Exception e) { e.printStackTrace(); return null; } }).filter(Objects::nonNull).collect(Collectors.toList()); flowTaskVo.setFiles(files); } this.flowTaskService.complete(flowTaskVo); preJb = willJb; } } } }
三、流程结束时遇到的问题(结束了但业务表状态未修改成功)
import cn.hutool.core.util.StrUtil; import lombok.AllArgsConstructor; import lombok.extern.slf4j.Slf4j; import cn.as.foundation.web.api.BusinessCode; import cn.as.foundation.web.exception.BusinessException; import cn.as.geekbidder.crm.contract.entity.ContractEntity; import cn.as.geekbidder.crm.contract.enums.ApprovalState; import cn.as.geekbidder.crm.contract.mapper.ContractNewMapper; import cn.as.maple.process.api.enums.FlowCommentEnum; import cn.as.maple.process.api.model.ListenerEvent; import cn.as.maple.process.api.model.ListenerEventSource; import java.util.Arrays; import java.util.Map; import java.util.Objects; import org.flowable.engine.HistoryService; import org.flowable.engine.RepositoryService; import org.flowable.engine.RuntimeService; import org.flowable.engine.history.HistoricProcessInstance; import org.flowable.engine.repository.ProcessDefinition; import org.flowable.engine.runtime.ProcessInstance; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.ApplicationListener; import org.springframework.core.annotation.Order; import org.springframework.scheduling.annotation.Async; import org.springframework.stereotype.Component; import org.springframework.util.Assert; import org.springframework.util.StringUtils; @Component @AllArgsConstructor @Slf4j public class ContractFlowEventListener implements ApplicationListener<ListenerEventSource> { @Autowired private RuntimeService runtimeService; @Autowired private RepositoryService repositoryService; @Autowired private ContractNewMapper contractNewMapper; @Autowired private HistoryService historyService; /** * 流程结束监听 * * @param event */ @Override public void onApplicationEvent(ListenerEventSource event) { callBackWithStateCal(event); } public synchronized void callBackWithStateCal(ListenerEventSource event){ log.info("------------------流程结束回调--------------------"); HistoricProcessInstance processInstance = historyService.createHistoricProcessInstanceQuery() .processInstanceId(event.getListenerEvent().getProcessInstanceId()) .singleResult(); if(Objects.isNull(processInstance)) { return; } String deploymentId = processInstance.getDeploymentId(); ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().deploymentId(deploymentId).singleResult(); if(Objects.isNull(processDefinition)) { return; } String defKey = processDefinition.getKey(); //只对发布的事件中关注的事件进行处理 boolean needDeal = Arrays.stream(ContractApproveGlobal.values()) .map(ContractApproveGlobal::getDefKey) .anyMatch(e -> e.equals(defKey)); log.info("------------------needDeal{}--------------------"+needDeal); if(needDeal) { String id = processInstance.getBusinessKey(); ListenerEvent listenerEvent = event.getListenerEvent(); String approvalResults = listenerEvent.getApprovalResults(); log.info("------------------approvalResults{}--------------------"+approvalResults); ContractEntity contractEntity = contractNewMapper.selectById(id); Assert.notNull(contractEntity, () -> { throw new BusinessException(BusinessCode.CLIENT_ERROR.getCode(), String.format( "合同id为"+ id + "的合同不存在,可能已被删除,请检查!!!")); }); if(FlowCommentEnum.NORMAL.getType().equals(approvalResults)) { ContractApproveGlobal dbNode = ContractApproveGlobal.getByCode(contractEntity.getApprovalNode()); ContractApproveGlobal nextNode = dbNode.getNearNode()[1]; contractEntity.setCurrentApprovalUser("无"); //上一个流程节点结束时将全局流程节点改为下一个节点 if(nextNode!=null && Integer.parseInt(nextNode.getCode()) <=3) { // 审批通过 contractEntity.setApprovalState("0"); contractEntity.setApprovalNode(nextNode.getCode()); } else { contractEntity.setApprovalState(ApprovalState.CHANGE.getCode()); } } else if(FlowCommentEnum.REJECT.getType().equals(approvalResults)) { // 审批驳回 Integer rejectCnt = contractEntity.getRejectCnt(); contractEntity.setCurrentApprovalUser("无"); rejectCnt = rejectCnt == null ? 0 : rejectCnt; contractEntity.setRejectCnt(rejectCnt+1); contractEntity.setApprovalState(ApprovalState.TERMINATION.getCode()); } else if("PROGRESS_IN".equals(approvalResults)) { contractEntity.setApprovalState(ApprovalState.EXECUTE.getCode()); } else if(FlowCommentEnum.REBACK.getType().equals(approvalResults)) { // 审批退回 contractEntity.setApprovalState(ApprovalState.UN_SUBMIT.getCode()); } contractNewMapper.updateById(contractEntity); } } }
原因总结:由于流程结束时使用了 runtimeService 取流程实例已经取不到了,导致后续的操作都失败了,使用 historyService 则可以避免此问题
四、流程前加签
@Override public void beforeAddSign(FlowTaskVo flowTaskVo) { TaskEntity currTask = (TaskEntity) taskService.createTaskQuery().taskId(flowTaskVo.getTaskId()).singleResult(); if(Objects.nonNull(currTask)) { String userId = this.userService.getUserIdByToken(); TaskEntity task = this.createSubTask(currTask, flowTaskVo.getAcceptUserId()); // 保存附件 FlowTaskVo subTaskVO = new FlowTaskVo(); subTaskVO.setFileIds(flowTaskVo.getFileIds()); subTaskVO.setFiles(flowTaskVo.getFiles()); subTaskVO.setTaskId(task.getId()); subTaskVO.setInstanceId(task.getProcessInstanceId()); this.saveAttachment(subTaskVO); this.deleteJob(flowTaskVo.getInstanceId()); this.taskService.addComment(task.getId(), flowTaskVo.getInstanceId(), FlowCommentEnum.ADD_SIGN.getType(), flowTaskVo.getComment()); this.taskService.saveTask(task); this.taskService.setAssignee(task.getId(), userId); this.taskService.complete(task.getId()); this.taskService.delegateTask(flowTaskVo.getTaskId(), flowTaskVo.getAcceptUserId()); this.taskService.deleteCandidateUser(flowTaskVo.getTaskId(), userId); TaskEntity oldTask = (TaskEntity) taskService.createTaskQuery().taskId(flowTaskVo.getTaskId()).singleResult(); oldTask.setName(oldTask.getName() + "-加办"); this.taskService.saveTask(oldTask); } else { throw new BusinessException(BusinessCode.CLIENT_ERROR.getCode(), "没有运行时的任务实例,请确认!"); } }
思路:前加签阶段生成一个子任务在子任务创建时设置办理人为指定的加签用户(创建阶段会触发TASK_CREATE事件、该事件中需要修改业务数据当前办理人),办理完结时设置办理人为当前用户(加签实际是当前用户办理的,这样在记录中查看时就能看到加签处理人),并办理完该子任务、 将原任务的办理人设置为指定的加签用户、并为原任务设置加签标识
五、配合完成时的操作修改当前任务审批人
@Transactional(rollbackFor = {Exception.class}) public void complete(FlowTaskVo flowTaskVo) { Map<String, Object> values = Collections.singletonMap("PROCESS_END_STATUS", FlowCommentEnum.NORMAL.getType()); TaskEntity task = (TaskEntity) ((TaskQuery) this.taskService.createTaskQuery().taskId(flowTaskVo.getTaskId())).singleResult(); this.deleteJob(flowTaskVo.getInstanceId()); String userId = flowTaskVo.getUserId(); if(StringUtils.isBlank(userId)) { userId = this.userService.getUserIdByToken(); } if(Objects.isNull(task)) { throw new BusinessException(BusinessCode.CLIENT_ERROR.getCode(), "任务不存在"); } else { if(DelegationState.PENDING.equals(task.getDelegationState())) { userId = this.userService.getUserIdByToken(); TaskEntity subTask = this.createSubTask(task, userId); this.taskService.addComment(subTask.getId(), flowTaskVo.getInstanceId(), FlowCommentEnum.DELEGATE.getType(), StringUtils.isBlank(flowTaskVo.getComment()) ? "同意" : flowTaskVo.getComment()); this.taskService.saveTask(subTask); // 保存附件 FlowTaskVo subTaskVO = new FlowTaskVo(); subTaskVO.setFileIds(flowTaskVo.getFileIds()); subTaskVO.setFiles(flowTaskVo.getFiles()); subTaskVO.setTaskId(subTask.getId()); subTaskVO.setInstanceId(subTask.getProcessInstanceId()); this.saveAttachment(subTaskVO); this.taskService.setAssignee(subTask.getId(), userId); this.taskService.setOwner(subTask.getId(), userId); this.taskService.complete(subTask.getId()); this.taskService.resolveTask(flowTaskVo.getTaskId(), values); TaskEntity oldTask = (TaskEntity) taskService.createTaskQuery().taskId(flowTaskVo.getTaskId()).singleResult(); oldTask.setName(oldTask.getName().replace("-加办", "")); this.taskService.saveTask(oldTask); } else { this.saveAttachment(flowTaskVo); this.taskService.addComment(flowTaskVo.getTaskId(), flowTaskVo.getInstanceId(), FlowCommentEnum.NORMAL.getType(), StringUtils.isBlank(flowTaskVo.getComment()) ? "同意" : flowTaskVo.getComment()); this.taskService.setAssignee(flowTaskVo.getTaskId(), userId); this.taskService.complete(flowTaskVo.getTaskId(), values); } } //加办阶段该值设置成了true CompletableFuture.runAsync(()->{ try { boolean addOper = task.getName().contains("-加办"); if(addOper) { TaskEntity cur = (TaskEntity)this.taskService.createTaskQuery().processInstanceId(flowTaskVo.getInstanceId()).singleResult(); List<IdentityLink> ids = this.taskService.getIdentityLinksForTask(cur.getId()); boolean specify = ids.stream().anyMatch(e -> "assignee".equals(e.getType())); String userNames = ids.stream().filter(e -> !specify || "assignee".equals(e.getType())).map(e -> { if(specify) { return userService.getUsersByIds(Collections.singletonList(e.getUserId())); } else { return userService.getUserByRole(e.getGroupId()); } }).flatMap(Collection::stream).map(User::getName).distinct().collect(Collectors.joining(",")); String instanceId = task.getProcessInstanceId(); ProcessInstance instance = this.runtimeService.createProcessInstanceQuery() .processInstanceId(instanceId) .active() .singleResult(); Thread.sleep(2000); ContractEntity contractEntity = contractNewMapper.selectById(instance.getBusinessKey()); if(contractEntity != null) { contractEntity.setCurrentApprovalUser(userNames); contractNewMapper.updateById(contractEntity); } } } catch(Exception e) { log.error(e.getMessage(), e); } }); }
六、查询阶段
public Page<FlowTask> todoList(ProcessTaskQuery query) { Page<FlowTask> page = new Page(); String userId = this.userService.getUserIdByToken(); List<String> roleIds = (List) this.roleService.getRolesByUserId(this.userService.getUserIdByToken()) .stream() .map(Role::getId) .collect(Collectors.toList()); if(!CollectionUtils.isEmpty(roleIds) && roleIds.size() != 0) { List list; if(StringUtils.isNotBlank(query.getProcessDefCategory())) { list = this.repositoryService.createProcessDefinitionQuery() .processDefinitionCategory(query.getProcessDefCategory()) .list(); } else { list = this.repositoryService.createProcessDefinitionQuery().list(); } Map<String, ProcessDefinition> processDefinitionMap = (Map) list.stream().collect(Collectors.toMap(ProcessDefinition::getId, Function.identity())); List<String> processKeys = (List) processDefinitionMap.values().stream().map(ProcessDefinition::getKey).collect(Collectors.toList()); TaskQuery taskQuery = (TaskQuery) ((TaskQuery) ((TaskQuery) ((TaskQuery) ((TaskQuery) ((TaskQuery) ((TaskQuery) ((TaskQuery) ((TaskQuery) this.taskService.createTaskQuery() .active() .includeProcessVariables()).or()).taskCandidateUser(userId)).taskAssignee(userId)).taskCandidateGroupIn( roleIds)).endOr()).processDefinitionKeyIn(processKeys)).orderByTaskCreateTime()).desc(); long count = taskQuery.count(); List<Task> taskList = taskQuery.listPage((query.getPage() - 1) * query.getSize(), query.getSize()); List<FlowTask> flowList = new ArrayList(); Iterator var11 = taskList.iterator(); while(var11.hasNext()) { Task task = (Task) var11.next(); ProcessDefinition pd = (ProcessDefinition) processDefinitionMap.get(task.getProcessDefinitionId()); FlowTask flowTask = new FlowTask(); flowTask.setVariable( Objects.nonNull(task.getProcessVariables()) ? this.filterVariables(task.getProcessVariables()) : null); flowTask.setTaskId(task.getId()); flowTask.setTaskDefKey(task.getTaskDefinitionKey()); flowTask.setCreateTime(task.getCreateTime()); flowTask.setProcDefId(task.getProcessDefinitionId()); flowTask.setTaskName(task.getName()); flowTask.setProcDefId(task.getProcessDefinitionId()); flowTask.setDueTime(task.getDueDate()); if(Objects.nonNull(pd)) { flowTask.setDeployId(pd.getDeploymentId()); flowTask.setProcDefName(pd.getName()); flowTask.setProcDefVersion(pd.getVersion()); } flowTask.setProcInsId(task.getProcessInstanceId()); HistoricProcessInstance historicProcessInstance = (HistoricProcessInstance) this.historyService.createHistoricProcessInstanceQuery() .processInstanceId(task.getProcessInstanceId()) .singleResult(); User startUser = this.userService.getUser(historicProcessInstance.getStartUserId()); flowTask.setStartUserId(Optional.ofNullable(startUser).map(User::getId).orElse("无")); flowTask.setStartUserName(Optional.ofNullable(startUser).map(User::getName).orElse("无")); flowTask.setStartDeptName(Optional.ofNullable(startUser).map(User::getOrganizationName).orElse("无")); flowList.add(flowTask); } page.setTotal(count); page.setRecords(flowList); page.setSize((long) query.getSize()); page.setPages((long) query.getPage()); return page; } else { throw new BusinessException(BusinessCode.LOGIN_EXPIRED.getCode(), "登录已过期,请重新登录"); } }
七、查询当前流程所在节点是不是最后一个节点
@Override public boolean isLastingNode(String contractId) { try { ContractEntity contractEntity = contractNewMapper.selectById(contractId); String approvalNode = contractEntity.getApprovalNode(); if(!ContractApproveGlobal.CONTRACT_PUBLISH_APPROVE.getCode().equals(approvalNode)) { return false; } String instanceIds = contractEntity.getInstanceIds(); String inst = instanceIds.substring(instanceIds.lastIndexOf(",") + 1); Task task = taskService.createTaskQuery().processInstanceId(inst).active().singleResult(); ExecutionEntity ee = (ExecutionEntity) runtimeService.createExecutionQuery() .executionId(task.getExecutionId()).singleResult(); // 当前审批节点 String currentActivityId = ee.getActivityId(); BpmnModel bpmnModel = repositoryService.getBpmnModel(task.getProcessDefinitionId()); FlowNode flowNode = (FlowNode) bpmnModel.getFlowElement(currentActivityId); // 输出连线 List<SequenceFlow> outFlows = flowNode.getOutgoingFlows(); boolean isLastNode = true; for (SequenceFlow sequenceFlow : outFlows) { // 下一个审批节点 FlowElement targetFlow = sequenceFlow.getTargetFlowElement(); if (targetFlow instanceof UserTask) { isLastNode = false; break; } // 如果下个审批节点为结束节点 if (!(targetFlow instanceof EndEvent)) { isLastNode = false; break; } } return isLastNode; } catch(Exception e) { return false; } }
