How to use a persistent H2 database in the Play Framework instead of in-memory
I found the solution.
To create a file database, modify the following:
From
db.default.url="jdbc:h2:mem:play"
To
db.default.url="jdbc:h2:file:data/db"
Where data/db
is broken down into:
data/
The folder location of the database files relative to your project root.
db
The name of your database files.
