Hi friends,

plz help me concept of lazy loading and batch loading with an example.


Thanks.

Hi

let say Class A has a set of Class B objects (one-to-many) . in our mapping file A.hbm.xml we can map that assosiation witha Set element. When we retirve a Class A object by session.get() or sessiong.find() etc. we will have A objects with set of B objects.

Say we don't want set of B's at some given time so we want to fetch only data related to A. (not B data) . So we have to mention it to hibernate. here comes lazy loading. We can say in our mapping file Set of B's must lazyly load. It means it will actually fetch at the time we use it. Otherwise it send a Set (not null) of proxies objects.

This is the rough idea for lazy loading.
