To bootstrap JPA and H2, add the following dependencies:

dependencies {
    ...
    implementation('org.springframework.boot:spring-boot-starter-data-jpa')
    runtimeOnly('com.h2database:h2')
    ...
}

Spring Configuration

Add in application.properties or equivalent:

spring.datasource.username=sa
spring.datasource.password=
spring.datasource.platform=h2

spring.datasource.initialization-mode=always
