flowable根据process_instance_id查询当前TaskDefinitionKey

Flowable是一个开源的工作流引擎，用于创建、管理和执行业务流程。如果你想要根据`process_instance_id`查询当前的任务定义键(Task Definition Key)，你可以通过Flowable的历史服务(History Service)来获取这个信息。以下是一个简单的步骤：

1. 首先，你需要一个运行Flowable的应用程序，它应该连接到了包含历史数据的数据库（通常是PostgreSQL或MySQL）。

2. 使用API或者库，如Spring Boot集成的Flowable REST API，你可以发送HTTP请求到类似这样的URL：

   GET /history/historic-task-instances?processInstanceId=<your_process_instance_id>

3. 请求成功后，服务器会返回一个JSON响应，其中包含有关任务实例的信息，包括`taskDefinitionKey`。例如：

   {
     "taskId": "task_123",
     "executionId": "exec_456",
     "processInstanceId": "your_process_instance_id",
     "taskDefinitionKey": "your_task_definition_key"
   }

4. 从返回的数据中提取`taskDefinitionKey`字段即可。
