Question

我在<代码>logback-sring.xml上有变数,我希望利用指挥线提供的价值,超越其违约价值。

<property name="log_root" value="${log.root:-logapp/logs}"/>
 <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log_root}/app.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${log_root}/archived/app.%d{yyyy-MM-dd}.log</fileNamePattern>
            <!-- keep 30 days worth of history, but at most 1GB -->
            <totalSizeCap>1GB</totalSizeCap>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%level %d [%thread] %logger{15} - %msg %ex{2}%nopex%n</pattern>
        </encoder>
    </appender>

我试图在杰尔呼吁中推翻价值:

java -jar app.jar -Dlog.root=logappv2/logs

But the app always use the default log.root value. What is possibly the cause?

Answer 1

这是你通过指挥线————————————————————传递的变量,但我看不到使用。

Answer 2

java - Dlog.root=logappv2/logs -jar app.jar
