        private String id;
        private String text;
        private String author;

        // constructors, getters and setters are ommited
    }

    @Document
    class Article {
        @Id
        private String id;
        @DBRef(lazy = true)
        @CascadeSave
        private List<Comment> comments;
        private String title;
        private String text;

        // constructors, getters and setters are ommited
    }
