When using H2 on a web application, don't forget to enable the console! Edit application.properties
as follow:
spring.h2.console.enabled=true
# replace "spring5webapp" by your own application
spring.datasource.url=jdbc:h2:mem:spring5webapp;DB_CLOSE_ON_EXIT=FALSE

General notes
Hibernate recommends to implement hashCode()
and equals()
on all JPA entities. They also recommend to use a particular Business ID when possible, if not then use the ID. Only the key fields should be in these methods.
How to run project
Spring boot provides some out-of-the-box tools.
To run the application:
# Using the maven installation (outside the project)
mvn spring-boot:run
# Using the embedded tool
./mvnw spring-boot:run
IntelliJ configuration
Useful plugings:
- File > Settings > Plugins > Browse repositories
- .ignore
- Ideolog
