Inversion of Confusion: What's up with all these containers?
A guide to the concepts behind Inversion of Control and a discussion of the similarities and differences between the best known of the containers, including Spring, HiveMind, Plexus, T5 IoC and Guice.
There's been a small explosion of IoC (Inversion of Control) containers over the last few years. It's not as confusing as the volume of web frameworks, but there is a lot of choices to be made. This session will identify the core features of an IoC container, and explain why using a container is such a powerful, enabling idea. We'll then cover some common cases, such as creating services with dependencies. Lastly, we'll discuss the pros and cons of each container, including how well they play with each other.
