I wouldn't boil down the concept of spring to this. However, one  
essential part
of Spring is the IoC Container which takes control of the whole  
lifecycle of
an object. Object relations are configurable which supports the  
concept of
componentry.

Please also note that Singletons are evil, especially in combination  
with unit testing.

yes, Dependency Injection is a very important feature for Unit Testing.

I don't think that it is either possible or makes sense trying to  
implement
a Component Manager or IoC Container for TYPO3 4.x. Please don't. Better
invest your energy into 5.0 which already has these features.

More importantly, Spring provides a framework for Aspect Oriented  
Programming
which is essential for Domain Driven Design and clean implementation  
of features
like persistence management etc.

Spring is very supportive when it comes to applying the Domain Model  
pattern, which
is one of the core concepts of TYPO3 5.0 as well.

Cheers,
