Setting logback.xml path programmatically

I know I can set the logback.xml path like this:

Specifying the location of the default configuration file as a system property

You may specify the location of the default configuration file with a system property named "logback.configurationFile". The value of this property can be a URL, a resource on the class path or a path to a file external to the application.

java -Dlogback.configurationFile=/path/to/config.xml chapters.configuration.MyApp1

but how can I do it in code?

Answer Source

You could use:

System.setProperty("logback.configurationFile", "/path/to/config.xml");

But it would have to happen before logback is loaded, i.e. something like:

class Main {
  static { System.setProperty("logback.configurationFile", "/path/to/config.xml");}
  private final Logger LOG = LoggerFactory.getLogger(Main.class);

  public void main (String[] args) { ... }

Note: I have not tested it but it should work.
