Get Class fields from annotated Object in annotation processor

i'm working on my first annotation processor. I'm trying to get fields of class through annotation on declared object(that is a field of a method). For example:

public class Person {
    private String name;
    private String surname;
}

...
public void myMethod(@MyAnnotation Person person) { 
    /*...*/
}
...

Through @MyAnnotation i want to get 'name' and 'surname' fields.

Is that possible? I did something of similar with method's field:

...
for (Element element : roundEnvironment.getElementsAnnotatedWith(AnnotationOnMethod.class)) {
    ExecutableElement method = (ExecutableElement) element;
    List<? extends VariableElement> parameters = method.getParameters();
    parameters.forEach(p -> {
        /*code here for parameter*/
    });
}
...

Thanks in advance, Luca.
