Implementing Controllers

Controllers play a crucial role in a web application: they execute the actual request, prepare the model, and select a view to render. In conjunction with the dispatcher servlet, controllers also play a crucial role in the request processing workflow. The controller is the glue between the core application and the web interface to the application. In this chapter, we will take a look at the two different controller approaches and cover the out-of-the-box implementations provided with the Spring Framework.

This chapter will also take a look at the supporting components for request processing. For example, we will cover form submission and how to apply internationalization (I18N).
