Re:Why I stopped using Spring

There's no sense at all in putting configuration of DI separately from the code. Normally, 99% of DI configs are not environment-specific (if this is not the case, "Houston, we have a problem"). In most cases you ship your software not like IKEA, but like Boeing - already assembled and ready for use. The customer (possibly, internal one) has to fill the fridge with meals for passengers and tanks with fuel, not to assemble the engines or avionics.

Wiring objects together and configuring applications are tangentially related. Both can be done in Spring config, both can be done without Spring config, both can be done at compile or runtime.
Dependency glue (wiring) in runtime config helps keep objects decoupled, makes test writing easier, and eliminates any dependency on a specific IOC framework. Whether or not the wiring config comes boxed with the code or not is a completely different concern.
