logback.xml不产生日志文件

Question

我有一个Spring项目，该 logback.xml：部署在WebLogic Server版本：12.2.1.0.0中，并且在weblogic控制台中看不到任何错误，我还看到了消息，但未生成日志文件

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

<appender name="rollingFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>C:/Work/logs/guerrilla.log</file>
    <!-- file>servers/${weblogic.Name}/logs/guerrilla.log</file-->
    <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
        <fileNamePattern>servers/${weblogic.Name}/logs/%d{yyyy,aux}/%d{MM,aux}/guerrilla.%d{yyyy-MM-dd}.%i.log.zip</fileNamePattern>
        <maxFileSize>100MB</maxFileSize>
    </rollingPolicy>
    <encoder>
        <pattern>%d{yyyy-MM-dd HH:mm:ss,SSS} %-5level [%thread] %logger{36}:%line - %msg%throwable%n</pattern>
    </encoder>
</appender>

<logger name="eu.europa" additivity="false">
    <level value="DEBUG"/>
    <appender-ref ref="rollingFileAppender"/>
    <appender-ref ref="consoleAppender"/>
</logger>

<root>
    <level value="INFO"/>
    <appender-ref ref="consoleAppender"/>
</root>

并且我在WL控制台中看到此消息：

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

我在pom.xml中有这个
