Configuring the Spring application context

We will use the Java configuration for configuring the application context of our application. The name of our application context configuration class is ApplicationContext, and its implementation is explained in the following points:

1. The @Configuration annotation is used to identify the class as an application context configuration class.

2. The @ComponentScan annotation is used to configure the base package of our controllers.

3. The @EnableWebMvc annotation is used to enable the Spring MVC.

4. The values of the configuration parameters are fetched from a property file that is imported by using the @PropertySource annotation. The Environment interface is used to access the property values stored in this file.
