How to set logback.xml properties in application.yaml

Question

I have logback.xml like this:

    <?xml version="1.0" encoding="UTF-8"?>
        <configuration scan="true" scanPeriod="2 seconds">

            <include resource="org/springframework/boot/logging/logback/base.xml"/>
            <jmxConfigurator/>

            <logger name="org.springframework" level="INFO"/>
            <logger name="org.springframework.web.filter.CommonsRequestLoggingFilter" level="DEBUG"/>
            <logger name="com.mypackage" level="WARN"/>

            <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
                <encoder>
                    <pattern>
                        %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
                    </pattern>
                </encoder>
            </appender>

            <turboFilter class="ch.qos.logback.classic.turbo.DynamicThresholdFilter">
                <Key>dynamicLogLevel</Key>
                <DefaultThreshold>DEBUG</DefaultThreshold>
                <MDCValueLevelPair>
                    <value>dynamicLogLevelDEBUG</value>
                    <level>DEBUG</level>
                </MDCValueLevelPair>
                <!-- dynamicLogLevelERROR for testing -->
                <MDCValueLevelPair>
                    <value>dynamicLogLevelERROR</value>
                    <level>ERROR</level>
                </MDCValueLevelPair>
            </turboFilter>

 .....
</configuration>

I want to set the logger level, appenders , rolling policy present in logback.xml in application.yaml .

I have gone through this Doc but did not find sufficient info.

I'm using spring-boot 1.4.4-RELEASE.

Answer 1

I found the solution: My application.yaml in some folder(say C:/configuration/application.yaml, c:/configuration/logback.xml).

In logback.xml , we can access application.yaml contents using :

<property file="${HOME}/configuration/application.yaml"/>

for ex: in application.yaml

LOG_FILE : C:/logs

in logback.xml access it:

<appender name="MY_APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_FILE}</file>

...

</appender>

But take care of value scanPeriod in

<configuration scan="true" scanPeriod="10 seconds">

Hope it will help.
