The Simple Web Application Module

The web application is defined in a simple-webapp project. This simple web application project is going to define two Spring MVC Controllers: WeatherController and HistoryController. Both of these controllers are going to reference components defined in simple-weather and simple-persist. The Spring container is configured in this application’s web.xml, which references the applicationContext-weather.xml file in simple-weather and the applicationContext-persist.xml file in simple-persist. The component architecture of this simple web application is shown in Figure 7-3.
