Hibernate does not provide an interface for controlling specifics of the cache such as you request.

Instead, you have to choose a cache implementation that provides that functionality, and configure it appropriately.

E.g. you can use EhCache and configure it like so:

<cache
    name="com.somecompany.someproject.domain.Country"
    maxElementsInMemory="10000"
    eternal="false"
    **timeToIdleSeconds="300"**
    **timeToLiveSeconds="600"**
    overflowToDisk="true"
/>

The two highlighted attributes above illustrate how you may configure the duration of cached time for the cached elements.

You would have to choose a L2 cache provider supporting expiration (EHCache, OSCache, JCS) and to configure the cache region for this particular request.
