Question

这是我的配置文件：

    <?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%msg%n"/>
        </Console>
        <File name="MyFile" fileName="file.log" immediateFlush="false" append="false">
            <PatternLayout pattern="%msg%n"/>
        </File>
    </Appenders>
    <Loggers>
        <Logger level="debug" includeLocation="true">
            <AppenderRef ref="MyFile"/>
        </Logger>
        <Root level="info">
            <AppenderRef ref="Console"></AppenderRef>
        </Root>
    </Loggers>
</Configuration>

如何更改：

在控制台
输出到file.debug所有具有调试级别的消息

爪哇：

   private static final Logger logger = LogManager.getLogger(Main.class);

public static void main(String[] args) {
  logger.info("info");
  logger.debug("debug");
}

问题是文件已创建，但它是空的......

谢谢
