You can run such kind of method, and provide ProductSearchCriteria as argument

private Set<String> getIntrospectedProperties(Class<?> productSearchCriteria) {
final BeanIntrospection<?> introspection =
BeanIntrospection.getIntrospection(productSearchCriteria);
return Arrays.stream(introspection.getPropertyNames()).collect(Collectors.toSet());
}
