本文介绍如何使用Flowable流程引擎（版本6.4.0）通过代码生成并部署流程定义，包括动态添加任务监听器以进行节点操作人的设置。演示了从开始事件到结束事件的完整流程设计，涉及用户任务、网关、服务任务等元素。

下面的代码主要功能是通过flowable代码生成流程定义并部署。节点添加task监听器，用于动态添加节点操作人等一些操作。 flowable为6.4.0 ，flowable用法很多可以参考activiti示例。

@Test
   public void generate() {
       //开始事件
       StartEvent startEvent = new StartEvent();
       startEvent.setId("start");
       startEvent.setName("开始");
       //审批节点
       UserTask userTask = new UserTask();
       userTask.setId("CATEGORYID_FILE_AUDIT");
       userTask.setCategory(FlowNodeCategory.SEAL_AUDIT.name());
       userTask.setCandidateUsers(Arrays.asList("2422042842433986573"));
       userTask.setName("审批节点1");
       //添加任务节点Listener

//permissinTaskListener 为实现TaskListener的一个类的bean名称

//非spring下可以这样用

//   listener.setImplementationType("class");
       // listener.setImplementation("实现类的全限定名");
       List<FlowableListener> taskListeners = new ArrayList<>();
       FlowableListener listener = new FlowableListener();
       listener.setEvent("all");
  listener.setImplementationType("delegateExpression");
       listener.setImplementation("${permissinTaskListener}");
       //listener.setId("CATEGORYID_FILE_AUDIT_listener");
       taskListeners.add(listener);
       userTask.setTaskListeners(taskListeners);
       //
       ExclusiveGateway fileGateway = new ExclusiveGateway();
       fileGateway.setId("FILE_GATEWAY");

       UserTask userTask2 = new UserTask();
       userTask2.setId("CATEGORYID_SEAL_AUDIT");
       userTask2.setCategory(FlowNodeCategory.SEAL_AUDIT.name());
       userTask2.setCandidateUsers(Arrays.asList("2198741168097853440"));
       userTask2.setName("审批节点2");

       ExclusiveGateway sealGateway = new ExclusiveGateway();
       sealGateway.setId("SEAL_GATEWAY");
//Service Task ，sealAuthDelegate 为实现JavaDelegate的spring bean 名称
       ServiceTask serviceTask = new ServiceTask();
       serviceTask.setId("SEAL_AUTH");
       serviceTask.setName("自动授权节点");
       serviceTask.setImplementationType("delegateExpression");
       serviceTask.setImplementation("${sealAuthDelegate}");

       //节点
       UserTask usesealTask = new UserTask();
       usesealTask.setCandidateUsers(Arrays.asList("${sealUsers}"));
       usesealTask.setId("CATEGORYID_SEAL_USE");
       usesealTask.setCategory(FlowNodeCategory.SEAL_USE.name());
       usesealTask.setName("使用节点");
       //拒绝
       EndEvent rejectEvent = new EndEvent();
       rejectEvent.setId("reject");
       rejectEvent.setName("拒绝");
       //结束事件
       EndEvent completeEvent = new EndEvent();
       completeEvent.setId("complete");
       completeEvent.setName("结束");

       SequenceFlow sequenceFlow = new SequenceFlow(startEvent.getId(), userTask.getId());
       SequenceFlow sequenceFlow2 = new SequenceFlow(userTask.getId(), fileGateway.getId());
       SequenceFlow sequenceFlow3 = new SequenceFlow(fileGateway.getId(),userTask2.getId());
       sequenceFlow3.setConditionExpression("${approve}");
       SequenceFlow sequenceFlow4 = new SequenceFlow(fileGateway.getId(), rejectEvent.getId());
       sequenceFlow4.setConditionExpression("${!approve}");
       SequenceFlow sequenceFlow5 = new SequenceFlow(userTask2.getId(), sealGateway.getId());
       SequenceFlow sequenceFlow6 = new SequenceFlow(sealGateway.getId(), serviceTask.getId());
       sequenceFlow6.setConditionExpression("${approve}");
       SequenceFlow sequenceFlow7 = new SequenceFlow(sealGateway.getId(), rejectEvent.getId());
       sequenceFlow7.setConditionExpression("${approve}");
       SequenceFlow sequenceFlow8 = new SequenceFlow(serviceTask.getId(),usesealTask.getId());
       SequenceFlow sequenceFlow9 = new SequenceFlow(usesealTask.getId(),completeEvent.getId());

       Process process = new Process();

       process.setName("业务防伪用印分类流程");
       process.addFlowElement(startEvent);
