Configuration

The configurations in this page can be set from several sources in the following order:

1. the operating system's environment variables; for instance, an environment variable can be set with export DB_URL="jdbc:mysql://db/elide?serverTimezone=UTC"
2. the Java system properties; for example, a Java system property can be set using System.setProperty("DB_URL", "jdbc:mysql://db/elide?serverTimezone=UTC")
3. a .properties file placed under CLASSPATH. This file can be put under src/main/resources source directory with contents, for example, DB_URL=jdbc:mysql://db/elide?serverTimezone=UTC
