hibernate: handle lazy-initialization manually ?

[Edward Chen]

In hibernate, how to handle lazy-initialization manually ? Say,

---People
   ---- Books[]
        ---- Reviews[]

Each people has many books, each of them has many reviews.

Certainly we have to set it as lazy. then how to load each level of lazy object manually to avoid n+1 problem and improve performance ?

Thanks

You can eagerly fetch associated objects via a query. Just specify the associated object in your join clause. Have a read of the documentation about eager fetching.
