This presentation was shown at Spring Framework Meeting 2009 in Cagliari (Sardinia - Italy).

Alfresco is the leading open source enterprise content management system and two of the most appreciated aspects of Alfresco are: the wide customization model and the high quality of source code.

Alfresco is strongly based on Spring Framework and thanks to this adoption we can find many ways to extend and inject our components. In this presentation will be shown many ways to extend Alfresco features and interfaces using Spring application context configuration.
