RE: [Springframework-developer] new bean factory and application context features

[Kopylenko, D. <dko...@ac...>]

Colin,

that will be possible when the metadata support and "magic"
TransactionAutoProxy creator will be in place ;-)

Regards,
Dmitriy.

Hi Juergen,

How do you see this being used (if at all) with the current=20
TransactionInterceptor, since its TransactionAttributeSource property=20
gets satisfied via a MethodMapTransactionAttributeSource instance =
(which

needs definitions in the format 'FQN.methodName'). While this works =
fine

when doing individual interceptors for use with ProxyFactoryBean, short =

of adding new code I'm at a loss as to how I could use=20
TransactionInterceptor with BeanNameAutoProxy to do transactions on all =

methods in all the beans I feed to the auto proxy.

Just wondering if I missed something?

Regards,
Colin
