Starting with Spring MVC 2.5, Annotation-Based Controllers became the preferred model for development (the Interface-based Controller hierarchy will be deprecated in Spring 3). This session will teach developers familiar with the old model how to use the new Annotation-based Controllers. This will also provide the basis for writing JSR 286 portlets using Spring 3.
