Q: 

Hibernate and 2nd level cache

I would like to

  • Cache instances of class Cat each time I call saveOrUpdate(Cat cat)
  • Retrieve Cat instances from the cache when I run a query findByName(String catName) - cat name is not a primary key

It looks like that the second level cache cannot help, because my understanding is that it works with primary keys only. Moreover, I am not even sure that the Cat instances will be put in the cache when I call saveOrUpdate(Cat cat).

Any suggestion? Thanks!
