In the past post, We had set-up a Kotlin SpringBoot project to develop with H2 database. But if you enable Spring Security in your project, the H2 database console will be blocked with 403 error. So in the tutorial, we will show you how to make configuration for resolving the Access Denied problem.
H2 database is a pure Java, open source and very fast engine. We can use H2 for development, testing and performance benchmarking. So in the tutorial, JavaSampleApproach will show how to integrate H2 database with Kotlin SpringBoot and Spring JPA in Embedded mode.
