java - log4j2 does not read spring boot property from correct configuration -

in log4j2.xml have following 2 properties:

<properties> <property name="log-path">logs</property> <property name="bootstrap.servers" value="${bundle:application:app.kafkabrokers}"></property> <property name="filename" value="${bundle:application:app.correctname}"></property> 

and following 2 appenders:

<kafka name="kafka" topic="logaggregation" >   <jsonlayout complete="false" compact="false" /> <patternlayout pattern="%date %message" />    <property name="bootstrap.servers">${bootstrap.servers}</property> </kafka> <rollingfile name="rollingfile" filename="${filename}"   filepattern="logs/$${date:yyyy-mm}/app-%d{mm-dd-yyyy}-%i.log.gz">   <patternlayout>     <pattern>%d %p %c{1.} [%t] %m%n</pattern>   </patternlayout>   <policies>     <timebasedtriggeringpolicy />     <sizebasedtriggeringpolicy size="250 mb" />   </policies> </rollingfile> 

kafkaappender reads property

bootstrap.servers

and rolling file reads property

filename

inside src/main/resources have following application.properties file:

app.kafkabrokers=localhost:9092 

app.correctname=log.txt

inside folder jar located have application.properties file following contents:

app.kafkabrokers=localhost:9092 app.correctname=correct.log

now if run java -jar springboot jar log4j2 not property file resides inside directory jar file is, stated in spring documentation here

the fact if write following code in main class:

  @postconstruct   public void init() {     system.out.println(env.getproperty("app.kafkabrokers") + "  "         + env.getproperty("app.correctname"));    } 

i see printed correct values such "correct.log" still log4j2 not new value , uses "log.txt"

what suspect log4j2 starts before spring pick correct application.properties file. ideas?
