Logback configuration live reload (scan=true) with Spring-Boot

Question

Okay guys I am trying to configure a a logback-spring.xml.

My goal is to automatically reload the configuration file upon modification.

So this is what the doc says :

FROM:

<configuration>
  ...
</configuration>

TO:

<configuration scan="true" scanPeriod="30 seconds">
  ...
</configuration>

There is no doubt that if I do not use any elements as :

<springProperty>

OR

<springProfile>

The live reload works with no problems. Also if I am not using the scan="true" springProfile and springProperty are working perfectly as well.

So my conclusion is that spring elements and scan do not like each other. I am getting errors from the type :

So as I already said if I remove scan=true the configuration works. If I remove springProfiles and properties and leave scan=true the configuration works again but with BOTH somethings is not right?

I assume the fact that it is most likely impossible to do so but did someone find a way of doing it?

EDIT: Close to a week after I posted my question Spring updated their documentation. Still I am looking for answer and I asume that there can be a way maybe using some middle layer of property file between Spring properties and logback configuration file because as the logback documentation says you can import property files into the configuration. But still even if so the problem with springProfile remains.

Answer 1

The Spring springProfile and springProperty elements have issues with scan.
