Logback日志级别更改不起作用

Question

我正在使用名为Apache Drill的应用程序，它使用logback进行日志记录。我试图编辑它的配置文件logback.xml以输出调试消息。

这里是文件的，不变的

    --> 

    <root> 
    <level value="error" /> 
    <appender-ref ref="STDOUT" />

</configuration> 

我所做的事后被编辑

<logger name="org.apache.drill" additivity="false"> 
    <level value="info" /> 
    <appender-ref ref="FILE" /> 
</logger> 

是

<logger name="org.apache.drill" additivity="false"> 
    <level value="debug" /> 
    <appender-ref ref="FILE" /> 
</logger> 

而且绝对没有什么变化！ 这是用于启动应用程序的Java命令（搜索-cp /home/gelbana/drillv11/conf的logback.xml文件位于的conf目录）

/usr/java/jdk1.8.0_112/bin/java -Xms10G -Xmx10G -XX:MaxDirectMemorySize=230G -XX:ReservedCodeCacheSize=1G -Ddrill.exec.enable-epoll=false -XX:MaxPermSize=512M -Djava.io.tmpdir=/home/gelbana/drillv11/tmp -Ddrill.memory.debug.allocator=true -XX:+CMSClassUnloadingEnabled -XX:+UseG1GC -Dlog.path=/home/gelbana/drillv11/log/drillbit.log -Dlog.query.path=/home/gelbana/drillv11/log/drillbit_queries.json -cp /home/gelbana/drillv11/conf:/home/gelbana/drillv11/jars/*:/home/gelbana/drillv11/jars/ext/*:/home/gelbana/drillv11/jars/3rdparty/*:/home/gelbana/drillv11/jars/classb/* org.apache.drill.exec.server.Drillbit 

的drillbit.out文件在开头

以下行

SLF4J: Class path contains multiple SLF4J bindings. 
SLF4J: Found binding in [jar:file:/home/gelbana/drillv11/jars/3rdparty/slf4j-simple-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class] 
SLF4J: Found binding in [jar:file:/home/gelbana/drillv11/jars/classb/logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class] 
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. 
SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory] 

我试图改变各级DEBUG，ALL但仍，没有任何改变。我在日志中找不到一个DBEUG。

Answer 1

您所做的更改应该工作。我做了相同的更改并运行钻头，我可以在drillbit.log中看到调试日志。例如：

DEBUG o.a.drill.exec.server.StartupOptions - 解析参数。

drillbit.out文件应该告诉你一些关于如何配置自身的Logback。看看这个文件，特别是其中涉及到LoggerContext例如条目：

找到的资源[logback.xml]在...

资源[logback.xml]在classpath中出现多次

而且您可能会发现Logback通过自己的日志记录揭示了答案。
