@Service into @Service

[Levisk]

Hi guys;
I have a doubt about how spring works.

Lets suppose we have 2 classes with the @Service anotation.
Then i wanna use some functionality from 1 of them into another.
How can i do it?

If i m with a lot of misunderstood concepts, can u guys give me a help?

thanks for your help :}

Lets suppose we have 2 classes with the @Service anotation.

Classes that are marked as @Service will get autodetected through classpath scanning.

Then i wanna use some functionality from 1 of them into another.

You'll have to wire them-up. Manual or Auto

@Service("clazname")
@Scope("session")

i just removed the @Scope and it workd

The core problem you're having here is injecting a Session-scoped bean into a Singleton. This can work, but you need to do a little more configuration.

See, singletons get injected once, at startup. This obviously won't work for session/request scoped beans, since the session isn't available until the request itself is issued. The solution is not to inject the scoped bean, but a proxy to that bean (that will be resolved when the actual call is made).

With XML, you'd just add a <aop:scoped-proxy/> tag to your scoped bean definition. You can't really do that with annotation-driven configuration, though. Instead, if you set up your component scanning like this:

<context:component-scan base-package="your package" scoped-proxy="interfaces"/>

Spring will automatically create proxies for all scoped beans discovered through component scanning. This should enable your code to work even with a @Scope("session").

Hope this helps
