Question

I’m trying to set a custom password for the sa user. My application.conf contains

db=mem
db.url=jdbc:h2:mem:play;MODE=MYSQL
db.driver=org.h2.Driver
db.user=sa
db.pass=newpass

…and the play framework appears to be overriding it inside play.db.DBPlugin

if(p.getProperty("db.url") != null && p.getProperty("db.url").startsWith("jdbc:h2:mem:")) {
    p.put("db.driver", "org.h2.Driver");
    p.put("db.user", "sa");
    p.put("db.pass", "");
}

How can I get around this?

Answer 1

As far as I’m aware this is because H2 in memory mode uses a default user/password, as it’s a RAM based db and it will be removed when the application stops and any changes to the user will be lost.

To avoid this you have to either use a “file” (not “mem”) instance of H2 or some other database.

I can’t think of an scenario where you want a memory database and changing the password is relevant. Could you explain the scenario and why you want to change the password? Maybe we can help by pointing an alternative.
