自由配置文件配置问题（log4j2）

Question

I can successfully set up log4j logging by setting up the following line within my jvm.options file:

-Dlog4j.configurationFile=C:/eclipse/runtime/usr/servers/tmpServer/log4j2.xml

However, I want to change this, so the path is not hard coded.

I was hoping this would work:

-Dlog4j.configurationFile=${server.config.dir}/log4j2.xml

But it does not. Any ideas why not?

I'm using liberty profile, and my log4j2.xml file is in the same directory as the jvm.options file.

Answer 1

jvm.options不支持Shell和变量扩展-检查此页面定制Liberty配置文件环境 -但是server.config.dir是默认的工作目录，因此设置： -Dlog4j.configurationFile=./log4j2.xml应该可以工作。
