Have an object

class Foo {
Long id; (the id)
String name;
}

that i get from the DB. I get it from the db using findByExample where i set the name as the example criteria and then get back the object with the id field populated.

I need to cache this for a period of time for performance but i don't fully understand how caching will work with this. I would like to cache all the values using EHCache as i don't want to keep hitting the DB. Do i have to enable query caching for this to work as i retrieve the values from the query?
Thanks
