We will set up a new Maven project for Vaadin application that will use the Spring framework. We will use a Java annotation-driven approach for Spring configuration instead of XML configuration files. This means that we will eliminate the usage of XML to the necessary minimum (for XML fans, don't worry there will be still enough XML to edit).
In this recipe, we will set up a Spring project where we define a bean that will be obtainable from the Spring application context in the Vaadin code. As the final result, we will greet a lady named Adela, so we display Hi Adela! text on the screen. The brilliant thing about this is that we get the greeting text from the bean that we define via Spring.
