Defining the API controllers

So far, we have written code to interact with the DB. Next up is to work on the code for the controller. We will have both types of controller—one that returns the view name (Thymeleaf template in our case) with the data for the view populated in the model object, and the other that exposes the RESTful APIs. We will need to add the following dependency to pom.xml:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${spring.version}</version>
</dependency>

Adding spring-webmvc to the dependency will automatically include spring-core, spring-beans, and spring-context dependencies. So we can remove them from the pom.xml.
