@admintertar thanks for the report but please refrain from posting source code like that. I've edited to remove the code of the class.

If you want support, the best is to provide a small sample that we can run ourselves. You can attach a zip to this issue or push the code to a GitHub repository. This will let us figure out if the MyBatis integration is responsible for trying to serialize MapperHelper (we obviously can't figure out how to do that automatically).

@snicoll Thank you for your reply, this is my demo, just run mvn -Pnative native:compile
java-version: GraalVM 21.0.4

win-native.zip

Thank you for the sample. @Mapper is a MyBatis component. It should handle things in such a way that's compatible with Spring AOT (and then native). Please review https://github.com/mybatis/spring-native and adapt your project accordingly. If that still does not work, please report that issue there.
