classpath中的logback.xml与logging.config环境参数spring boot一起执行

Question

I have a spring boot project(version 1.3.6) and i have added logback.xml to the project. On creating an executable jar, the logback.xml is getting included in the jar and also working as expected. As the development is done on a windows system, so logback.xml in classpath adds the logs to file at path F:/application/logs/abc.log.

But on deployment of the jar on unix server, i want to provide logback.xml configuration from external file with a different path for logging file say (/opt/logs/abc.log) . I used -Dlogging.config argument while executing my jar file to provide the external logback.xml configuration file as below.

java -Dlogging.config=/path/to/logback.xml -jar ABC.jar

On running the above command, the logs are getting created successfully at /opt/logs/abc.log as per the external file configuration but the issue is that F:/application/logs/abc.log directory structure also gets created with a 0 byte file though no logging is being done in this.

So if i am running my application from say /local directory on the server, then the below directories are getting created.

/local/F:/application/logs/abc.log

My question is how can we avoid the classpath log file directory structure( /local/F:/application/logs/abc.log ) from getting created if external logback.xml configuration is used.

My logback.xml is below.

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
<appender name="ROLLINGFILE"
    class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>F:/FRF/logs/iqcx-ticketing.log</file>
    <append>true</append>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>F:/FRF/logs/iqcx-ticketing-%d{yyyy-MM}.%i.zip
        </fileNamePattern>
        <maxHistory>10</maxHistory>
        <timeBasedFileNamingAndTriggeringPolicy
            class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>20MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
    <encoder>
        <pattern>%date{ISO8601} [%thread] - %-5level %logger %X - %msg%n
        </pattern>
    </encoder>
</appender>
<root>
    <appender-ref ref="ROLLINGFILE" />
</root>
<logger name="iqcxLogger" level="info">
    <appender-ref ref="ROLLINGFILE" />
</logger>
<logger name="org.springframework" level="info" additivity="false">
    <appender-ref ref="ROLLINGFILE" />
</logger>
<logger name="org.mybatis.spring" level="info" additivity="false">
    <appender-ref ref="ROLLINGFILE" />
</logger>
<logger name="org.hibernate.validator" level="info" additivity="false">
    <appender-ref ref="ROLLINGFILE" />
</logger>
<logger name="org.apache.commons.beanutils" level="info" additivity="false">
    <appender-ref ref="ROLLINGFILE" />
</logger>

</configuration>

由于logback.xml在类路径F中：除非您通过在命令行中添加-Dlogging.file=/opt/logs/abc.log参数来覆盖logging.file属性，否则将创建/application/logs/abc.log。
