Configuration path of Log4j2

Question

I am trying to adopt Log4j2 to my project. Since my Java Application is packeted in a JAR file. I don't want "log4j2.xml" configuration packaged inside of JAR file. I am trying to learn how configuration file works from "http://logging.apache.org/log4j/2.x/manual/configuration.html"

But seems there is no clear instruction regarding altering the configuration file path of the Log4j2.

After googling about this topic I found something like "Referencing log4j config file within executable JAR" Referencing log4j config file within executable JAR, But this solution is not available any more according to "http://logging.apache.org/log4j/2.x/manual/migration.html" (if I understand it correctly).

So I am wondering if someone have any idea about this issue.

Thanks

Answer 1

You can set the system property to specify the configuration path. set the

"-Dlog4j.configurationFile="D:\learning\blog\20130115\config\LogConfig.xml" 

in VM arguments. replace

"D:\learning\blog\20130115\config\LogConfig.xml"

to your configuration path.

1. Put the log4j2.xml file in resource directory in your project so that the log4j will locate files under class path automatically.

Loading log4j2.xml file from the customized location-

1. You can use the System property/ VM arguments- Dlog4j.configurationFile=file:/path/to/file/log4j2.xml This will work for any web application.

2. For some legacy applications, you can create a class for loading log4j2.xml/ log4j2.properties from the custom location on the machine like- D:/property/log4j2.xml Using any of these approach,during application startup, the log4j2.xml file from the src/resources folder will be overridden by the custom location log4j.xml file.
