hi



in the tutorial (page 170) there is:
hibernate.cache.use_query_cache true

then :
List blogs = sess.createQuery("from Blog blog ")
.setMaxResults(15)
.setCacheable(true)
.setCacheRegion("frontpages")
.list();



My question is:
How can i retrieve what is in the cache? How can I work with?

thanks

julien

From documentation:" Query result sets may also be cached. This is only useful for queries that are run frequently with the same parameters".
Hibernate reuse de query results. Is not necessary get the cache contents.
see : http://www.hibernate.org/hib_docs/reference/en/html_single/#performance-querycache

ok thanks but I don't uderstand what thats means and how can iwork with it.

please help me

Set hibernate.show_sql true and try to execute your method. You'll find that Hibernate generates a SQL statement (and executes it) to fulfill your request, in your example getting all Blog objects.
If you execute the same method another time, no SQL is executed and data is simply taken from cache.
You don't have to worry about cache management.
