來自線程here的此代碼可以幫助您獲取taskID。

JournalArticle journalArticle = JournalArticleLocalServiceUtil.getArticle(id); 
      getPermissionChecker().init(u.getUser(), true); 
     WorkflowInstanceLink wil= WorkflowInstanceLinkLocalServiceUtil.getWorkflowInstanceLink(companyId, journalArticle.getGroupId(), JournalArticle.class.getName(), journalArticle.getId()); 
     WorkflowInstance workflowInstance = WorkflowInstanceManagerUtil.getWorkflowInstance(companyId, wil.getWorkflowInstanceId()); 
     Map<String, Serializable> workflowContext = workflowInstance.getWorkflowContext(); 

     List<Integer> logTypes_assign = new ArrayList<Integer>(); 
     logTypes_assign.add(WorkflowLog.TASK_ASSIGN); 
     List<WorkflowLog> workflowLogs_assign = WorkflowLogManagerUtil.getWorkflowLogsByWorkflowInstance(companyId, wil.getWorkflowInstanceId(), logTypes_assign, QueryUtil.ALL_POS, QueryUtil.ALL_POS, WorkflowComparatorFactoryUtil.getLogCreateDateComparator(true)); 
     //WorkflowPermissionUtil.hasPermission(permissionChecker, groupId, className, classPK, actionId); 

     if(workflowLogs_assign.size() > 0){    
      long taskId = workflowLogs_assign.get(workflowLogs_assign.size()-1).getWorkflowTaskId(); 
      WorkflowTask task = WorkflowTaskManagerUtil.getWorkflowTask(companyId, taskId); 
      _log.info("task : "+task.getName()); 
      WorkflowTask nextTask = WorkflowTaskManagerUtil.assignWorkflowTaskToUser(companyId, userId, task.getWorkflowTaskId(), userId, "auto assign", task.getDueDate(), workflowContext);    
      WorkflowTaskManagerUtil.completeWorkflowTask(companyId, userId, nextTask.getWorkflowTaskId(), "next task transition name", "next task name", workflowContext); 
     } 

謝謝。
