Spring register dynamics class

I use graalvm features,my project need to generate dynamics class,so i need to register it,originally ,I can implements RuntimeHintsRegistrar,but since my class is dynamics generated,i want to register inside my business code,any soultion can provider for me? thanks a lot

original method:

class xx implements RuntimeHintsRegistrar{

  @Override
  public void registerHints(RuntimeHints hints, ClassLoader classLoader) {
    hints.reflection().registerType(Trace1.class, hint ->
      hint.withMembers(MemberCategory.INVOKE_DECLARED_CONSTRUCTORS, MemberCategory.INVOKE_PUBLIC_CONSTRUCTORS));
     }
  }

What do you mean by dynamically generated? Can you share a code snippet showing how this class is generated? Can you also explain what's known at build time and what is only known at runtime?

i use mybatis generator api generator class,which is similar to mybatis generator plugin generating classs

I think this needs to be run at build time - we can't generate random types at runtime without knowing anything in advance about them. This should be done during the AOT phase, there are dedicated contracts for that.

can i use javassit or asm to change byte code to achieve it?

Comment From: bclozel

There is no bytecode at runtime in a native image.

use build time compiler tool like maven-aspectj-plugin can achieve it?
