Slf4j with log4j2 not working Spring boot 1.4.3.RELEASE - spring

Question

I was using Spring boot 1.3.6.RELEASE and log4j2.yml as below:
Configuration:
status: info
Properties:
Property:
name: log-path
value: "/dvl-log/pol/apps/logs/api"
Appenders:
Console:
- name: Console
target: SYSTEM_OUT
PatternLayout:
Pattern: "%d{HH:mm:ss.SSS} %-5level %logger{1} - %msg%n"
Loggers:
Root:
level: info
AppenderRef:
- ref: Console
Logger:
- name: com.company.api
level: trace
additivity: false
AppenderRef:
- ref: Console
level: trace
The logging with below code was working perfectly.
#Slf4j
public class LogExample{
public void logMethods(String className,String methodName){
log.trace("{} >> {}", className, methodName);
}
}
But when I upgraded to Spring Boot 1.4.3.RELEASE, the logger is not working.
My new build.gradle after upgrading to 1.4.3 is (just a version change)
version '1.0'
// dependencies for command line
buildscript {
ext {
springBootVersion = '1.4.3.RELEASE'
dependencyManagementVersion = '0.5.2.RELEASE'

}
What thing I'm missing here? TIA
I want to add more details:
there are log4j-api:2.6.2, log4j-core:2.6.2 and log4j-slf4j-impl:2.2.6 on classpath after upgrading to Spring Boot 1.4.3. The thing is appender is not working for trace level because I am getting log for info or above level.

Answer 1

I resolved this problem by moving log4j2.yml directly into resource directory.
Earlier, with Spring Boot 1.3.6, I had put log4j2.yml under resources/logging directory with configuration.yml as
logging:
config: classpath:logging/log4j2.yml
I don't know why it didn't work for 1.4.3.RELEASE.
