如何在activiti7中获取用户任务中的窗体属性？

import org.activiti.engine.FormService;
import org.activiti.engine.TaskService;
import org.activiti.engine.form.FormProperty;
import org.activiti.engine.form.TaskFormData;
import org.activiti.engine.task.Task;

// 获取用户任务中的窗体属性
public class GetTaskFormPropertiesExample {
    public static void main(String[] args) {
        // 获取任务ID
        String taskId = "your-task-id";

        // 获取TaskService和FormService
        TaskService taskService = processEngine.getTaskService();
        FormService formService = processEngine.getFormService();

        // 查询任务
        Task task = taskService.createTaskQuery().taskId(taskId).singleResult();

        // 获取任务的表单数据
        TaskFormData taskFormData = formService.getTaskFormData(taskId);

        // 获取窗体属性
        List<FormProperty> formProperties = taskFormData.getFormProperties();

        // 遍历窗体属性
        for (FormProperty formProperty : formProperties) {
            // 获取属性的名称、类型、默认值等信息
            String propertyName = formProperty.getName();
            String propertyType = formProperty.getType().getName();
            String propertyValue = formProperty.getValue();

            // 打印属性信息
            System.out.println("属性名称：" + propertyName);
            System.out.println("属性类型：" + propertyType);
            System.out.println("属性默认值：" + propertyValue);
        }
    }
}
