There are several points to mention. But don't worry we will get you where you want to be. 1. Guice modules do not get injected. Modules define what is binded in the injector. This means the modules are used to construct the injector. So they exist before the injector does. This makes it

You canot intercept methods on instances created by a provider. What guice does is to create a subclass of the thing you want to to intercept. But when you use a provider to create this object you are calling new yourself which makes it impossible for guice to sneak in the subclass. Therefore
