I use the in-memory database that comes with Play Framework, when I have db=mem
in the configuration file, for development.
How can I connect to this database using JDBC? and not the JPA that is the default way.
I have tried with this method in my controller:
public static void addToDB() {
try {
Connection conn = DriverManager.getConnection("jdbc:h2:mem:play");
Statement stmt = conn.createStatement();
stmt.execute(sql);
stmt.close();
conn.clos开发者_如何转开发e();
} catch (SQLException e) {
e.printStackTrace();
}
}
But I get an error message that I need to provide an username and password:
org.h2.jdbc.JdbcSQLException: Wrong user name or password [8004-149]
If I visit the web-console on /@db
the username sa
is used and no password.
Now I logged in via the /@db
interface and created a table users
.
Then I connected to the database in a controller method and used this jdbc-string: jdbc:h2:mem:play:sa
and then tried to insert to the table users
but I get this error message:
org.h2.jdbc.JdbcSQLException: Table "USERS" not found; SQL statement:
How should I connect to the in-memory H2 database in Play Framework using JDBC?
DB.getConnection()
, should do the job.
Try:
Connection conn = DriverManager.getConnection("jdbc:h2:mem:play", "sa", "");
because as you wrote, "the username sa is used and no password."
