I am using second level cache with Hibernate. EHCache is being used as second level cache. I am able to load my objects in cache using session.find() method. But when I try to use session.iterate() method to get objects from cache , I get Cache miss for every single object and iterate() method goes to DB for every object and load it.

Can somebody please inform me why iterate() method is getting a cache miss when all the objects are in second level cache? According to EHCache documentation, iterate() method always goes to cache to retrieve the objects.

I am using EHCache 1.1 and Hibernate 2.8.


Thanks

Have you implemented equals() and hashcode() on your entities? I never can remember all the details on these, but I remember they can affect caching if not implemented correctly.

I am using both equals() and hashCode() methods but they are never being called.

I am getting following things:

sc.magistrate.data.Address cache - Miss

2005-07-21 17:01:21,017 DEBUG: Element for sc.framework.loadcache.Key@625b625b is null

2005-07-21 17:01:21,017 DEBUG: Cache miss

2005-07-21 17:01:21,027 DEBUG: object not resolved in any cache [sc.magistrate.data.Address#sc.framework.loadcache.Key@625b625b]



After this it goes to DB and try to load from there.

If anybody can provide any pointers etc.?


Thanks
