Initially, before implementing the domain model's dependencies and configuration, the class needs to be specified. The following Maven starter dependency needs to be included:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    ...
    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <version>1.4.197</version>
    </dependency>
</dependencies>

The preceding entries will import all the dependencies of the JPA stack, and an embedded H2 database that can be used to store entities.
