RE: [Springframework-developer] RE: About CGLIB2

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

I've just fixed it by re-introducing an inner class CglibProxyFactory: =
Grab the current AdvisedSupport from CVS, and a JDK proxy will work with =
Hibernate 2.1 - without the need for cglib1.jar in the class path. I've =
tested it with Petclinic, and it works nicely.

We should stick to that inner-class strategy when migrating to CGLIB2, =
to let people use Hibernate 2.0.x or iBATIS Database Layer (with CGLIB1 =
underneath).

I guess in my refactoring I lost the indirection by which a CGLIB proxy =
was
created only by an inner class, to prevent dependence on CGLIB at =
runtime.
I'll try to sort that out tomorrow or Monday.

Btw, the TransactionProxyFactoryBean now extends the new ProxyConfig, =
which
has a proxyTargetClass property that defaults to false. Set it to true =
to
force CGLIB. Otherwise it won't use CGLIB by default.

Rod

This
poses the question whether we should still release our 1.0 M4 with =
CGLIB1
support. Of course, our current codebase works nicely with Hibernate 2.1 =
as
long as you don't use CGLIB-based AOP proxies (i.e. proxy full target
objects instead of just interfaces), so we don't *have* to update
immediately.
