In this chapter, we will see how to create a JDBC connection with H2 database and the CRUD operations with the H2 database. By default, Spring Boot configures the application to connect to an in-memory store with the username sa and an empty password.. spring.main.banner-mode=off spring.datasource.platform=h2 spring.datasource.driverClassName=org.h2.Driver spring.datasource.url=jdbc:h2:mem:testdb;MODE=PostgreSQL #logging.level.org.springframework=ERROR The application.properties is the main Spring Boot configuration file.
