Answer 1

Hibernate already provides a caching mechanisms called 1st level cache by the persistent context . It is in the Session scoped , enabled by default and cannot be turned off.

The cache provider such as EHCache provides another caching mechanisms called 2nd level cache . It is in the SessionFactory scoped . No 2nd level cache is enable by default and you have to configure it .

See this for how to enable EHCache in hibernate.
