    Understanding JBossCache - Caching an object graph with many associations

    Oliver Weiler Newbie

      I'm trying to use JBossCache as a JPA/Hibernate 2nd level cache provider to cache repeatedly called queries. The queries return entities of a specific type, lets call it FooType.


      FooType looks like the following:


      @Entity(name = FooType)

      @Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)

      public class FooType {

        protected BarType barType;


        @ManyToOne(targetEntity = BarType.class, cascade = { CascadeType.ALL })

        BarType getBarType() {

          return barType;




      So, Footype has a many-to-one association. Now, when I call the query, only a very small part seems to be put in the cache. I think the reason is because I didn't mark the association with the @Cache tag. Am I correct?

      But the real question is:

      BarType also has a handful of associations, and these return objects which also provide associations and so on, building a big graph of associations. Now, do I need to

      a) annotate all of those classes and b) also annotate the associations

      in order for the whole query to be cached?
