在运行时通过外部属性文件更改日志记录中的日志级别 [英] Change log level in logback at run time via external property file

问题描述

我想在不重新启动服务器的情况下更改日志级别.我使用weblogic服务器.为此，我想通过外部文件(LOGBackIncludedFile.xml)传递日志级别，并在logback <include file>中提供此文件路径. 我无法对路径进行硬编码，因为Dev，UAT，Production中的路径不同.我想将此文件包含在Weblogic 12C服务器内部的某个位置.因此，我无需更改ear文件即可更改日志级别.

I want to change the log level without restarting the server. I use weblogic server. For this I thought to pass the log level from a external file (LOGBackIncludedFile.xml) and give this file path in the logback <include file>. I cannot hard code the path, as the path is different in Dev, UAT, Production. I want to include this file in a location inside Weblogic 12C server. So I can change log level without touching ear file.

<configuration  scan="true"  scanPeriod="30 seconds">

   <include file="../../LOGBackIncludedFile.xml" />
   <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender" >
       <encoder>
         <pattern>%date %-5level [%logger] > %msg%n</pattern>
       </encoder>
  </appender>

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

下面是LOGBackIncludedFile.xml

<included>
  <property value="INFO" name="root.level"/>
</included>

使用现有的xml时，出现此错误.

when I use this existing xml I get this error.

 java.io.FileNotFoundException: /usrXX/appXX/oracle/product/XXX/domains/XXXDomain/../../LOGBackIncludedFile.xml 

我的问题是如何在logback.xml中动态设置外部文件路径.路径应为特定的weblogic instance.当我将外部文件放入实例中时.

My question is how can I set external file path dynamically in the logback.xml. The path should be to the specific weblogic instance. As I put the external file into my instance.

例如:/usrxx/appxx/oracle/product/XXX/domains/xxxDomain/servers/myInstance/

推荐答案

按如下所示设置文件路径.这是针对weblogic 12C的.

Set the file path as below. This is for weblogic 12C.

 <include optional="true" file="${DOMAIN_HOME}/servers/${SERVER_NAME}/LOGBackIncludedFile.xml" />
