flowable通过代码创建流程

  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 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());

        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());
