genuinner opened a new issue, #16430: URL: https://github.com/apache/dolphinscheduler/issues/16430
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened When i try to parse json to complex class(like BaseHeartBeat.class), there will be a ClassCastException. That is because the JSONUtils.toMap(String json, Class<K> classK, Class<V> classV) uses TypeReference to parse json which cannot deal generic type correctly, we can use MapType instead. ``` public void toGenericMap() { String json = "{\"beatHeart\":{\"processId\":18,\"host\":\"192.168.1.1\"}}"; Map<String, BaseHeartBeat> models = JSONUtils.toMap(json, String.class, BaseHeartBeat.class); Assertions.assertEquals(18, models.get("beatHeart").getProcessId()); } ``` ### What you expected to happen no exceptin should be throw ### How to reproduce just parse the json to any custom class ### Anything else _No response_ ### Version dev ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
