Class UnitOfWorkFilter

java.lang.Object

at.ipsquare.commons.servlet.UnitOfWorkFilter

All Implemented Interfaces:

javax.servlet.Filter

public class UnitOfWorkFilter
extends Object
implements javax.servlet.Filter

This class implements a Filter that wraps entire web requests in UnitOfWork instances using the configured HibernateRepository instances.

This servlet filter is an implementation of the session-per-request pattern. By default, you also get one transaction per request, but nobody hinders you from doing more fine grained transaction management if you need it.
