Avoid reflecting to obtain validationGroups every time the call is made

Lines 241 to 245 in 1a52c56

	private Class<?>[] getValidationGroups() {
	return ((shouldValidateArguments() || shouldValidateReturnValue()) && this.methodValidator != null ?
	this.methodValidator.determineValidationGroups(getBean(), getBridgedMethod()) : EMPTY_GROUPS);
	}

can call getValidationGroups() in the InvocableHandlerMethod construction method, and take validationGroups returned by getValidationGroups() method as a member variable. Avoid reflecting to obtain validationGroups every time the call is made

can call getValidationGroups() in the InvocableHandlerMethod construction method

You can not do that because methodValidator is set after construction, I've fixed this by #32078

@quaff Sorry, my previous description was incorrect. I would like to correct it. Would it be better to initialize validationGroups in method setMethodValidator(@Nullable MethodValidator methodValidator),

example code:

public void setMethodValidator(@Nullable MethodValidator methodValidator) {
   this.methodValidator = methodValidator;
   this.validationGroups = getValidationGroups();
}
