[QUESTION]json.parse在读取带下划线的变量转驼峰要如何全局设置？

例如
String jsonStr = {"user_id": 1111};
变量名userId;
有什么办法可以全局设置码

Start by reading fastjson2's JSON parsing and deserialization configuration APIs, focusing on whether a global naming strategy can map the shown user_id field to userId. Done means confirming the supported configuration or identifying the missing capability with a minimal example based on the issue's JSON and Java variable names.
