based on http://os890.blogspot.co.at/2013/12/add-on-spring-bridge-with-deltaspike.html it's possible to write e.g. a cdi bridge for spring-mvc. with that it's possible to use cdi-beans as spring-mvc controllers. please notice that it is just a feasibility study.
https://github.com/os890/cdi-spring-mvc-showcase/tree/cdi-managed is the current state of the official demo with cdi-beans as controllers (instead of spring-beans).
