read value from application properties in spring-log4j2.xml file

Say I have log4j2-spring.xml file with all the configuration of the appenders. There is a way to inject to the xml value from application.properties file?

My spring-log4j2.xml look like that:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
    <Syslog name="ElkLogs" host="${logstash.host}" port="5002" protocol="UDP"> 
    </Syslogs>
    <Async name="AsyncElkLogs">
    <AppenderRef ref="ElkLogs"
    </Async> 
</Appenders>
<Loggers>
    <Root>
        <AppenderRef ref="AsyncElkLogs"/>
    </Root>
</Loggers>
</Configuration>

my application-dev.properties file:

logstash.host=elk-dev-1

my application-prod.properties file:

logstash.host=elk-prod-1

I found another solution to my problem that decrease the coupling between the enviroments.

I created two configuration files, one for each enviroment with the names spring-log4j2-dev.xml and spring-log4j2-prod.xml

and edit my application.properties files to look like that:

application-dev.properties:

logging.config=classpath:spring-log4j2-dev.xml

application.properties:

logging.config=classpath:spring-log4j2-prod.xml

class="org.springframework.beans.factory.config.PropertiesFactoryBean">
 <property name="locations">
<list>
  <value>file:/relase/location1env/env1.properties</value>
  <value>file:/relase/location2env/env2.properties</value>
