日志记录多个记录器不符合级别

    </appender>

    <root level="ERROR">
        <appender-ref ref="ROOT_FILE_APPENDER" />
    </root>

    <logger name="it.pkg.testpkg.service" additivity="true" level="INFO">
        <appender-ref ref="basic-text"/>
    </logger>

</configuration>

private static final Logger LOGGER = LoggerFactory.getLogger(it.pkg.testpkg.service.EchoService.class);

现在，问题是，当我以以下方式进行日志记录时：

LOGGER.info("Test Log");

尽管根记录器级别被设置为“错误”，但日志条目仍然存在于两个日志文件中。然而，当我去掉“it.pkg.testpkg.service”记录器（通过注释或删除它）时，条目停止进入根记录器。我不太清楚这是怎么回事。

目前，我已经找到了一个临时解决方案，方法是在“root_file_appender”中添加以下条目：

<filter class="ch.qos.logback.classic.filter.LevelFilter">
     <level>ERROR</level>
     <onMatch>ACCEPT</onMatch>
     <onMismatch>DENY</onMismatch>
</filter>

谢了。

通过可加性达到的祖先记录器的行为跳过日志级别检查。

如果记录器

<logger name="it.pkg.testpkg.service" additivity="true" level="INFO">
    <appender-ref ref="basic-text"/>
</logger>

接受log语句

LOGGER.info("Test Log");

<logger name="it.pkg.testpkg.service" additivity="false" level="INFO">
    <appender-ref ref="basic-text"/>
    <appender-ref ref="ROOT_FILE_APPENDER" />
</logger>
