Java - Not able to get value of Custom Annotation using Reflection

I'm trying to generate a report and the fields should be in the specified sequence. As this is microservices architecture, I've a db service where interface based projection is used. On top of it, I'm trying to use a custom annotation to maintain the order.

Custom Annotation:

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Sequence {
        int value();
}

Interface based Projection DTO :

public interface ReportDTO {

@Sequence(value = 1)
String getId();

@Sequence(value = 2)
String getName();

@Sequence(value = 3)
String getMobileNumber();

}

In another micoservice, I'm deploying this db service and utilising as below:

private static List<String> getFieldNamesForClass(Class<?> clazz) throws Exception {
    List<String> fieldNames = new ArrayList<String>();
    Method[] methods = clazz.getMethods();

    Arrays.sort(methods, (o1, o2) -> {
        boolean isPresent = o1.isAnnotationPresent(Sequence.class);
        
        Sequence or1 = o1.getAnnotation(Sequence.class);
        Sequence or2 = o2.getAnnotation(Sequence.class);
        // nulls last
        if (or1 != null && or2 != null) {
            return or1.value() - or2.value();
        } else
        if (or1 != null && or2 == null) {
            return -1;
        } else
        if (or1 == null && or2 != null) {
            return 1;
        }
        return o1.getName().compareTo(o2.getName());
    });
    for (Method method : methods) {
        if (method.getName().substring(0, 3).equals("get") && !method.getName().equals("getDecoratedClass")
                && !method.getName().equals("getTarget") && !method.getName().equals("getTargetClass"))
            fieldNames.add(lowerFirst(method.getName().substring(3)));
    }
   
    return fieldNames;
}

But this code is unable to figure out the annotation. Variable "isPresent" returns false and or1 and or2 are null. Please help me figure out the issue with this code.
