Creating a project

To create a project, go to  https://start.spring.io and create a Kotlin-based project. Here are the dependencies of the project:

• Web
• JDBC
• MySQL
• DevTools
• JPA
• H2

You can find these in the pom.xml file. There you can update, add, or remove the dependencies.

To enable JPA auditing, you need to annotate @EnableJpaAuditing annotation on the SocialNetworkApplication.kt class. It will enable the use of JPA functionalities.

Here is the code for this class:

@SpringBootApplication
@EnableJpaAuditing
class SocialNetworkApplication

fun main(args: Array<String>) {
   runApplication<SocialNetworkApplication>(*args)
}
