How can I use @Query result in SDN3?

I'm using Spring Data Neo4j 3.0.0 in my web site.

I have some problem doing develope. I use @Query Annontation in @NodeEntity model class.

@Query(value = "START a=node({self}) MATCH (a)<-[:`COMMENT_TO`]-(b) RETURN b ORDER BY    b.createdAt DESC")
private Set<BaseComment> sortedComments;

and I try to use this result...then sortedComments type was SpringEndResult. How can i use this result to Set ?

and can I use this in .jsp? when I using sortedComments in jsp with JSTL(c:foreach). I met SpringEndResult doesn't have property exception.

I'm not english native. Thanks for your response. :)

@Test
public void getList() {
    List<SimpleArticle> articles = articleService.getAll(0, 10).getContent();
    for (SimpleArticle simpleArticle : articles) {
        Set<BaseComment> comments = simpleArticle.getSortedComments();
        for (BaseComment baseComment : comments) {
            log.info(baseComment);
        }
    }
}

And I met

java.lang.ClassCastException: org.springframework.data.neo4j.rest.SpringEndResult cannot be cast to kr.carcare.model.bbs.BaseComment

This is my domain class

public class SimpleArticle extends BaseArticle {

@RelatedTo(type = "COMMENT_TO", direction = Direction.INCOMING)
@Fetch
private Set<BaseComment> comments;

@Query("START a=node({self}) MATCH (a)<-[:`COMMENT_TO`]-(b) RETURN b ORDER BY b.createdAt DESC")
private Set<BaseComment> sortedComments;

Try using SpringEndResult's "as" method and feed it something like Set.class (or something similar that implements Iterable).

I can't recall if that's the exact syntax, but, the "as" method takes a class parameter that extends Iterable, where R is the template type; in your case, R is BaseComment.
