[Springframework-developer] IJdbcTemplate / IHibernateTemplate / ISqlMapTemplate

[<jue...@we...>]

Everybody,

Due to a recent request, I've just extracted IHibernateTemplate and =
ISqlMapTemplate interfaces, analogous to IJdbcTemplate that Rod =
introduced a while ago. They are intended to ease mocking for =
unit-testing DAOs, for those who want to mock at this level. For typical =
DAO implementations, the standard template classes are good enough, =
allowing for mocks of the underlying persistence tool and live tests =
against a database.

However, I wonder about the naming. We don't have the I* pattern =
anywhere else in the framework; on the other hand, we need to keep the =
old template names for compatibility (and some templates don't lend =
themselves for such an interface, like JdoTemplate). IHibernateTemplate =
etc doesn't worry me, but maybe a different name like =
HibernateOperations would be better? Essentially, those interfaces =
specify a set of data access operations for a particular persistence =
tool.

The naming isn't too important, though, as it will not be the main API =
that people will work with; the template classes will be. We'll just let =
the templates implement those operation interfaces to allow for mocking =
them if desired. BTW, iBATIS SQL Maps is all based on concrete classes =
rather than interfaces, not allowing to mock the persistence tool =
itself.
