在liferay中以编程方式执行工作流转换？

Question

我在我的工作流的最后一步有两个名为“批准”和“拒绝”的转换，但我想从我的portlet控制工作流操作。

有人知道如何以编程方式在liferay中执行工作流转换？

Answer 1

workflowInstance1 = WorkflowInstanceManagerUtil.signalWorkflowInstance(service.getCompanyId(), user.getUserId(), 
      workflowInstanceId, transitionNAME, workflowInstance.getWorkflowContext()); 

Answer 2

我当前的代码

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); 
      }
