i want to implement spring 5 with log4j2 profile, like dev, qa and prod.

At present, This is how i run my spring 5 with log4j2, i load the log4j2 properties in command line:

mvn tomcat8:run -Dlog4j.configurationFile=file:%path_to_log4j2_prop%/log4j2.properties

and this is my log4j2 properties:

status = debug
name = PropertiesConfig
 
#Make sure to change log file path as per your need
property.environment=D:/WhiteCoats-New-Workspace/spring-5
property.servicesfilename = ${environment}/wc.out
 
filters = threshold
 
filter.threshold.type = ThresholdFilter
filter.threshold.level = debug
 
appenders = services
 
appender.services.type = RollingFile
appender.services.name = ServiceFile
appender.services.fileName = ${servicesfilename}
appender.services.filePattern = ${environment}/wc.out-%d{yyyy-MM-dd}-%i
appender.services.layout.type = PatternLayout
appender.services.layout.pattern = [ %d{yyyy-MMM-dd HH:mm:ss a} ] - [%t] %-5level %logger{36} - %msg%n
appender.services.policies.type = Policies
appender.services.policies.time.type = TimeBasedTriggeringPolicy
appender.services.policies.time.interval = 1
appender.services.policies.time.modulate = true
appender.services.policies.size.type = SizeBasedTriggeringPolicy
appender.services.policies.size.size=5MB
appender.services.strategy.type = DefaultRolloverStrategy
appender.services.strategy.max = 10

loggers = services
 
#services logs
 
logger.services.name = com.vm
logger.services.level = debug
logger.services.additivity = false
logger.services.appenderRef.services.ref = ServiceFile

rootLogger.level = info
rootLogger.appenderRef.stdout.ref = ServiceFile

In spring 3, i used log4j and configured the path in web.xml.

how do i implement profiles for log4j2 for spring 5?

In Spring Boot, if you need to change the property log4j.configurationFile it is very simple within the application.yml. You define the default, and the override value in case you use a profile. For example:

log4j:
    configurationFile: %path_to_log4j2_prop%
---
spring:
    profiles: development
log4j:
    configurationFile: %path_to_dev_log4j2_prop%
---
spring:
    profiles: production
log4j:
    configurationFile: %path_to_prod_log4j2_prop%

If you use Spring only, than you can use @Configuration with @Profile and @PropertySource to load different property files according to your profile, and in those files you can set your log4j.configurationFile property based on your needs.
