CFML: working MySQL datasource in Application.cfc (this is just a note-to-self/Google)


No content in this one, I just want something I can find when I search for how to config a MySQL datasource in Application.cfc in ColdFusion. I always forget/lose the code, and I can never find anything on Google. It'd be marvellous of Adobe would document this stuff, but it's a bit much to expect of them, I guess.

component {


    private void function setSettings() { = "app1"

    private void function loadDataSources() {
        this.datasources["dsn1"] = {
            driver = "mysql",
            class = "com.mysql.jdbc.Driver",
            url = "jdbc:mysql://database.backend:3306/"
                & "#server.system.environment.MARIADB_DATABASE#"
                & "?useUnicode=true&characterEncoding=UTF-8",
            username = server.system.environment.MARIADB_USER,
            password = server.system.environment.MARIADB_PASSWORD
        this.datasource = "dsn1"

The bit I always forget is the class bit, so I end up with an error along these lines:

No driver or URL found.

java.sql.SQLException: No driver or URL found.
