如何通过反射找到标注了特定注解的字段？

import java.lang.annotation.Annotation;
import java.lang.reflect.Field;

public class ReflectionExample {
    public static void main(String[] args) {
        Class<?> targetClass = TargetClass.class;

        Field[] fields = targetClass.getDeclaredFields();
        for (Field field : fields) {
            Annotation[] annotations = field.getAnnotations();
            for (Annotation annotation : annotations) {
                if (annotation instanceof MyAnnotation) {
                    System.out.println("Found field with MyAnnotation: " + field.getName());
                }
            }
        }
    }
}

class TargetClass {
    @MyAnnotation
    private String field1;

    @MyAnnotation
    private int field2;

    private String field3;
}

@interface MyAnnotation {
}
