Project Creation

We will create a project for understanding database relationships by going to Spring Initializr. Create a Maven project with the latest stable version of Spring Boot. Use the following project metadata values:

• Group id: io.datajek

• Artifact id: database-relationships

For this project, the following dependencies are needed:

1. Spring Data JPA which is Spring’s JPA implementation using Hibernate ORM framework.

2. Spring Web which supports web applications as well as REST services.

3. H2 database which is an in-memory database.

4. Spring Boot Devtools which adds the auto restart functionality.

Click "Generate" to download the project. Unzip and import in the IDE. Now we will add the Jackson dependency for Hibernate 5. This dependency provides support for Hibernate datatypes and specifically handles aspects of lazy-loading. We are adding it manually as this dependency is not available in Spring Initializr.
