Question

I want to use a common xml in my logback-spring.xml? how to include the xml in logback-spring.xml without getting an error. I got that to include an xml in our logback-spring.xml we need to use but somehow this is not working for me. I have invested so much time but no results. https://dennis-xlc.gitbooks.io/the-logback-manual/content/en/chapter-3-configuration/configuration-file-syntax/file-inclusion.html

The file which has to be used inside the logback-spring.xml must not contain the <xml> tag. The file should be like below. The <included> tag must be used in file which has to be loaded inside another file.

    <included>
            <property name="LOGS" value="./logs" />
            <property resource ="application.yml"/>
            <springProperty name="NAME" source="spring.application.name" />
            <appender name="Console"
                class="ch.qos.logback.core.ConsoleAppender">
                <layout class="ch.qos.logback.classic.PatternLayout">
                    <Pattern>

                    </Pattern>
