If I restart the Rest server, H2 database reset

Question

I used file db as below:

spring.datasource.url=jdbc:h2:file:./data/meet

And I can find file "meet.mv.db" in my working directory.

If I add tuples to the file and restart the server, the size of the file increases. However, I cannot get what is inside the file after restarting. That means there is no persistency at all.

Can anyone help me to find how to obtain persistency?

Answer 1

In application.properties:

spring.jpa.hibernate.ddl-auto=update

(from https://docs.spring.io/spring-data/jpa/docs/1.4.3.RELEASE/reference/html/jpa.repositories.html)

Answer 2

I ran into a similar problem and I discovered it was because I had this property set in the persistence.xml file:

<property name="hibernate.hbm2ddl.auto" value="create-drop" />

Removing this line fixed the issue and data was still there after server restart.
