inject factory created object?

[klc]

Hi all I have a servlet app that read a configuration file on settings of different services (>1000), like auto commit.

And when a request come in, it use this configuration to create a per request context object for services to use.

Now for the context object i can use assisted inject to create them by factory. but how do I re-inject them in services, instead of passing them explicitly?

You can bind the object in request scope.

Would this need the injector?

I think i have to be more specific for a solid advice :)

I guess the thing I don't understnad is how to transit from singleton servlet to request scoped objects

for eg I have a singleton servlet to process a request, to use request scoped object i have to use a provider class. (https://github.com/google/guice/wiki/Scopes#scopes-and-concurrency)

but the provider class need inject of request scope object as well (eg httpservletrequest), ie:

@Singleton

public class Servlethandler ... {

    @Inject

    Provider<RequestScopeObj> obj

}

public class RSprovider {

    @Inject

    public RSprovider(HttpServletRequest req) {...}

}

As servlet handler is singleton, i don't understand how to request scope object would work.
