覆盖登录配置 [英] Overriding logback configurations

问题描述

有什么方法可以覆盖回滚配置?我知道我们在名为logback.xml的文件中定义了logback配置(通常存储在路径src/main/resources中)，并且我知道通过使用<include>标记，我们可以设置要添加到logback.xml的外部文件，如下所示:

<configuration>

<!--<include url="file:///d:/ServerConfig.xml"/>-->
<include file="${outPut}/ServerConfig.xml"/>


<logger name="Server" LEVEL="DEBUG">
    <appender-ref ref="FILEOUT" />
</logger>

<root level="DEBUG">
    <appender-ref ref="STDOUT" />
    <!--<appender-ref ref="FILEOUT" />-->
</root>

</configuration>

但是，如果我想覆盖此默认配置怎么办?例如，将根记录器级别设置为INFO.

这是包含的文件:

<included>

<!-- <property file="d:/ServerSysVar.properties"/>-->
<property file="${outPut}/ServerSysVar.properties"/>


<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
</appender>



<appender name="FILEOUT" class="ch.qos.logback.core.FileAppender">
    <file>${Sys_Location}/Serverfile4.log</file>
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} %class{36}.%M %L CLIENT_PORT:%X{ClientPort}- %msg%n</pattern>
    </encoder>
</appender>


<logger name="Service" LEVEL="DEBUG">
    <appender-ref ref="FILEOUT" />
</logger>

 <root>
    <appender-ref ref="STDOUT" />
   <!-- <appender-ref ref="FILEOUT" />-->
</root>

</included>

解决方案

我认为您不能从包含的文件中覆盖logback.xml-定义.

但是，我有一种方法可以使用使用默认值的变量替换:

logback.xml

<configuration>
  <include file="includedFile.xml" />

  <!-- STDOUT appender stuff -->

  <root level="${root.level:-DEBUG}">
    <appender-ref ref="STDOUT" />
  </root>
<configuration>

includedFile.xml

<included>

  <!-- override the default value; or comment out to leave it at default -->
  <property name="root.level" value="INFO" />

</included>

有了这个概念，我什至可以控制从包含的文件到多个追加器的输出:

logback.xml

<configuration>
  <include file="includedFile.xml" />

  <!-- STDOUT appender stuff -->

  <appender name="FILE" class="ch.qos.logback.core.FileAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>${file.level:-ALL}</level>
    </filter>
    <file>/path/to/logfeil.log</file>
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>${syslog.level:-OFF}</level>
    </filter>
    <syslogHost>localhost</syslogHost>
    <facility>${syslog.facility:-LOCAL1}</facility>
    <suffixPattern>${syslog.pattern:-[%thread] %logger{36} - %msg}</suffixPattern>
   </appender>

  <logger name="my.package" level="${logging.level:-INFO}" additivity="false">
    <appender-ref ref="FILE" />
    <appender-ref ref="SYSLOG" />
  </logger>

  <root level="${root.level:-DEBUG}">
    <appender-ref ref="STDOUT" />
  </root>
<configuration>

在includedFile.xml中，我可以控制是否通过附加程序FILE和SYSLOG以及在什么级别上传递消息，设置属性file.level，syslog.level以及当然是logging.level. /p>

Is there any way that we can override the logback configurations? I know that we define the logback configurations in file named logback.xml (usually stored in the path src/main/resources) and I know that by using <include> tag we can set an external file to be added to logback.xml just like below:

<configuration>

<!--<include url="file:///d:/ServerConfig.xml"/>-->
<include file="${outPut}/ServerConfig.xml"/>


<logger name="Server" LEVEL="DEBUG">
    <appender-ref ref="FILEOUT" />
</logger>

<root level="DEBUG">
    <appender-ref ref="STDOUT" />
    <!--<appender-ref ref="FILEOUT" />-->
</root>

</configuration>

But what if I want to override this default configuration? For example set the root logger level to INFO.

Here is the included file:

<included>

<!-- <property file="d:/ServerSysVar.properties"/>-->
<property file="${outPut}/ServerSysVar.properties"/>


<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
</appender>



<appender name="FILEOUT" class="ch.qos.logback.core.FileAppender">
    <file>${Sys_Location}/Serverfile4.log</file>
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} %class{36}.%M %L CLIENT_PORT:%X{ClientPort}- %msg%n</pattern>
    </encoder>
</appender>


<logger name="Service" LEVEL="DEBUG">
    <appender-ref ref="FILEOUT" />
</logger>

 <root>
    <appender-ref ref="STDOUT" />
   <!-- <appender-ref ref="FILEOUT" />-->
</root>

</included>

解决方案

I don't think that you can overwrite logback.xml-definitions from an included file.

But I have an approach that solves your question regarding overriding the root-logger-level, using variable substitution with default values:

logback.xml

<configuration>
  <include file="includedFile.xml" />

  <!-- STDOUT appender stuff -->

  <root level="${root.level:-DEBUG}">
    <appender-ref ref="STDOUT" />
  </root>
<configuration>

includedFile.xml

<included>

  <!-- override the default value; or comment out to leave it at default -->
  <property name="root.level" value="INFO" />

</included>

With that concept, I've even been able to control the output to multiple appenders from the included file:

logback.xml

<configuration>
  <include file="includedFile.xml" />

  <!-- STDOUT appender stuff -->

  <appender name="FILE" class="ch.qos.logback.core.FileAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>${file.level:-ALL}</level>
    </filter>
    <file>/path/to/logfeil.log</file>
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>${syslog.level:-OFF}</level>
    </filter>
    <syslogHost>localhost</syslogHost>
    <facility>${syslog.facility:-LOCAL1}</facility>
    <suffixPattern>${syslog.pattern:-[%thread] %logger{36} - %msg}</suffixPattern>
   </appender>

  <logger name="my.package" level="${logging.level:-INFO}" additivity="false">
    <appender-ref ref="FILE" />
    <appender-ref ref="SYSLOG" />
  </logger>

  <root level="${root.level:-DEBUG}">
    <appender-ref ref="STDOUT" />
  </root>
<configuration>

And in the includedFile.xml I can control if, and at what level message shall pass through the appenders FILE and SYSLOG, setting the properties file.level, syslog.level and of course logging.level.
