// Rendering dynamic forms 

    @GetMapping(path = "/formDataShow")

    public AjaxResponse formDataShow(String taskId) {

        try {

            if(GlobalConfig.Test){

                securityUtil.logInAs("bajie");

            }

            Task task = taskRuntime.task(taskId);

            UserTask userTask = (UserTask)repositoryService.getBpmnModel(task.getProcessDefinitionId())

                    .getFlowElement(task.getFormKey());

            List<FormProperty> formPropertiesList = userTask.getFormProperties();

            for(FormProperty formProperty:formPropertiesList){

            }

            return AjaxResponse.ajaxData(GlobalConfig.ResponseCode.SUCCESS.getCode(),

                    GlobalConfig.ResponseCode.SUCCESS.getDesc(),null);

        }catch (Exception e){

            return AjaxResponse.ajaxData(GlobalConfig.ResponseCode.ERROR.getCode()," Failed to render dynamic form ！",null);

        }

    }

Task task = taskRuntime.task(taskId);

            UserTask userTask = (UserTask)repositoryService.getBpmnModel(task.getProcessDefinitionId())

                    .getFlowElement(task.getFormKey());

            List<FormProperty> formPropertiesList = userTask.getFormProperties();

            for(FormProperty formProperty:formPropertiesList){

            }

Among them, we get the task through acquisition , And then through the form key（task.getFormKey()） To get to the userTask, In theory, we should transfer the task key That is to say ：

Only with this value can we get the properties of the form , But we can't get this key, So only when drawing the flow chart , We put the form key Task related key Set to consistent , In this way, we pass in the key That is, with the task key Consistent to get userTask 了 .

Let's draw the flow chart ：

The executors of the two tasks are designated as bajie, Then we put the form key All assigned to task key Agreement .

Then we just add a few forms as shown in the figure , Write values casually , Then the process is downloaded and released .

Then call the interface we wrote above , View the attribute values of the form ：

It seems that we haven't got any data , Just get a form type and key.

But we can use another way to get the data ：
