在log4j2配置文件中使用pom.xml SystemProperty

Question

There is a property in my pom.xml that I'd like to use in log4j2.xml. However log4j2 seems to not detect that property and the file cannot be created.

The property is defined in a following way:

<systemProperty>
    <name>log.location</name> 
    <value>${project.build.directory}/logs</value>
</systemProperty>

And that how I refer to that in a log4j2.xml:

fileName="${sys:log.location}"

Answer 1

In your log4j2.xml file Use <property name="fileName">${filename}</property> // this will fatch your filename from pom.xml

than use "${fileName}" wherever you want to use in your log4j2. this way it will work.
