log4j的不写入文件，但其写入到控制台

Question

我在基于Linux的系统中，我使用SLF4J库记录

进口org.slf4j.Logger aritinga小的应用程序; import org.slf4j.LoggerFactory;

我可以看到日志在控制台中可见但不会附加到日志文件。

<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> 
    <param name="threshold" value="INFO" /> 
    <layout class="org.apache.log4j.PatternLayout"> 
     <param name="ConversionPattern" value="[%d{ABSOLUTE}][%-5p][%-10t]%m%n" /> 
    </layout> 
</appender>

Answer 1

它已被确定，我必须包括sl4j-log4j桥jar来解决上述问题，我包括log4j和sl4j个人罐子，由于这个我可以看到没有编译错误，但桥没有履行。

删除单个罐子并添加桥接罐问题已解决。

Answer 2

我已检查logback.xml文件配置。看起来根标签（“配置”）缺失。你可以添加并检查它？

参考https://logback.qos.ch/manual/configuration.html

Answer 3

看来你错过了根标签在XML文件中。请找到下面的代码将日志写入文件。

<appender name="file" class="org.apache.log4j.RollingFileAppender"> 
    <param name="append" value="false" /> 
    <param name="maxFileSize" value="128MB" /> 
    <param name="maxBackupIndex" value="20" /> 
    <param name="file" value="./logs/audit.log" /> 
    <layout class="org.apache.log4j.PatternLayout"> 
     <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" /> 
    </layout> 
</appender> 

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

Answer 4

问题中显示的配置为log4j 1.2格式。

log4j2.xml的格式不同。它是基于插件的，所以你不需要再指定appender的类名。

请参阅Log4j2 manual。它有很多示例配置。
