Accessing the application properties in logback.xml

Question

Is it possible to access application properties of spring boot in log back xml.

application.properties

dummy.property=hello
<         


        

Answer 1

According to the http://logback.qos.ch/manual/configuration.html#variableSubstitution

Variables can be defined one at a time in the configuration file itself or loaded wholesale from an external properties file or an external resource.
...
The property is not declared in the configuration file, thus logback will look for it in the System properties.

Logback can use system properties or properties defined explicitely. So you need to tell logback to use application.properties file
