[logback-user] Configuring logback with variable substitution

Hi people! I have an issue. I want to use variable substitution to configure logback.xml, which works fine. But I also want to set substitutionProperty file value with the java -D argument when I start up my server. Some thing lige this: java -Dlogback.config="/path/to/my/property/file" <configuration debug="true"> <substitutionProperty file=${logback.properties} />
