template for interceptor stack?

[fox9]

Hi,

is there a way to defne some form of template for an interceptor stack?

I have a lot of services defined in a spring application context that should all be intercepted by a stack of the same interceptors. Instead of defining a ProxyFactoryBean with a list of the same interceptors *for every* service, I like to define this interceptor-list only once and wire it with the least possible amount of typing in the application context xml file.

Thanks for any hints that could help me!

Hi Felix,

I am also interested in that approach. If you read my recent posting (http://forum.springframework.org/showthread.php?t=12675) you'll see that I tried to create a parent "EnterpriseBeanTemplate" to apply a series of interceptors to several POJOs.

Unfortunately Spring throws an Exception during application context initialization.

Another approach I am trying is to use BeanNameAutoProxyCreator to apply interceptor stacks to several beans identified by name (with wildcards). Several interceptors/advisors use source code annotations to figure out the pointcut. So far this approach is working nicely.

Best regards,
Fernando

Thanks Fernando, the <bean ... abstract="true"> and <bean ... parent="..."> stuff was basically what I was looking for.

Just to complete this topic: there are also the 'autoproxying' facilities of Spring described in chapter 5.10 of the Spring reference manual. Autoproxying is probably a bit more comfortable (i.e. there's no need to have the target bean with a different name), but it also includes the disadvantage of beeing a bit more "automagic" by not explicitly expressing what is happening (IMHO one of the big dangers with AOP anyway).

Cheers,
Felix
