Of course there are many options we may wish to set for a MySQL database. These options may be specified as part of the JDBC connection string simply by prefixing each server option with server.. In the following example we set two driver parameters and two server parameters:

        String url = "jdbc:mysql://" + hostColonPort + "/"
                + "?"
                + "cacheServerConfiguration=true"
                + "&"
                + "useLocalSessionState=true"
                + "&"
                + "server.basedir=/opt/myapp/db"
                + "&"
                + "server.datadir=/mnt/bigdisk/myapp/data";
  

Starting with Connector/MXJ 5.0.6 you can use the initializer-user property to a connection string. If set to true, the default anonymous and root users will be removed and the user/password combination from the connection URL will be used to create a new user. For example:

        String url = "jdbc:mysql:mxj://localhost:" + port
        + "/alice_db"
        + "?server.datadir=" + dataDir.getPath()
        + "&server.initialize-user=true"
        + "&createDatabaseIfNotExist=true"
        ;
