JSON.register在springboot3下无效

JSON.register(A.class, new ASerializer());
这个在springboot3下无效，请教下怎么配置能全局生效呢

Start by reproducing the reported JSON.register(A.class, new ASerializer()) call in a Spring Boot 3 application and compare its behavior with the same registration outside Spring Boot. Trace the relevant configuration entry points and determine what is needed for the serializer registration to apply globally; done means the custom serializer is used throughout the application.
