Dependency injection and related techniques

I would like to demonstrate here the most interesting features and styles of use of common Dependency Injection containers. I will use common sample which should also demonstrate the differences among single containers.

Why this page? To be honest I created it to preserve interesting code snippets for later use among other things. I hope you will also find it useful.

The DI containers I will use:

1. Spring - older but still very popular, mostly because with Spring the developers gets a framework that addresses almost any area in software development. XML for configuration is dead - so we will use Java based configuration solely.
2. Guice - super elegant and concise DI, but don't expect much more
3. CDI - standard in JavaEE 6, differs from Spring mostly when it comes to handling scopes
4. (one for Scala world later)

The main focus in samples is on (might change):

1. Injection (type-safety, support for generics)
2. Factories
3. Parameters / Partial injections
4. Constants
5. Scopes
6. Interceptors
7. Events

Real World Use cases:

1. Transactional service
2. Type-safe configuration 
3. Caching
4. Remoting
