Add annotations to indicate the order of the fields automatically

Background:

The order of Class.getDeclaredFields() is not specified in Java, so I want to add annotations to fields to indicate order of field like this:

public final class Model {
    @Order(1)
    String item1;

    @Order(2)
    String item2;

    @Order(3)
    String item3;

    @Order(4)
    String item4;
}

But it is too tough to add these annotations to all classes.

Question:

Is there any way to add annotations to indicate the order of the fields automatically?

I had a look around the document of Lombok, but there is no feature like that.
