I'm trying to use Log4j2 to print the spring logs into a file and console. I guess it is a problem in my Log4j2 configuration. I have not been able to get it working. I have this configuration in my log4j2.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<configuration name="defaultConfiguration" status="warn" strict="true" monitorInterval="5">
<properties>
<property name="patternlayout">%d{ISO8601} [%t] %-5level %logger{36} - %msg%n%throwable{full}</property>
<property name="filename">${env:MY_ROOT}/logs/mylog.log</property>
<property name="filenamePattern">${env:MY_ROOT}/logs/mylog-%d{yyyy-dd-MM}-%i.log.gz</property>
</properties>
<appenders>
<appender name="Console" type="Console" target="SYSTEM_OUT">
<layout type="PatternLayout" pattern="${patternlayout}" />
</appender>
<appender name="File" type="RollingFile" fileName="${filename}" filePattern="${filenamePattern}" bufferedIO="true" immediateFlush="true"
append="true">
<layout type="PatternLayout" pattern="${patternlayout}" />
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="50 MB" />
</Policies>
<DefaultRolloverStrategy max="30" />
</appender>
<appender name="AsynchFile" type="asynch" blocking="true" bufferSize="128">
<appender-ref ref="File" />
</appender>
</appenders>
<loggers>
<root level="info">
<appender-ref ref="Console" />
<appender-ref ref="AsynchFile" />
</root>
<logger name="org.springframework.beans">
<appender-ref ref="Console" />
<appender-ref ref="AsynchFile" />
</logger>
</loggers>
</configuration>
These are the dependencies that I have in my pom file: (probably some of them are not required)

I'm not doing anything related to spring in my Java code. I'm using the Main class from Apache Camel which reads my spring configuration and loads the beans.
What am I doing wrong? Thanks!
Edit: I am not getting spring logs in any output (console or file). However, I am able to get the logs I create in my java code. I hope this clarification will help.
In a Spring Boot application, you can specify a Log4J 2 XML configuration file as log4j2. xml or log4j2-spring. xml in the project classpath. The Spring Boot team however recommends using the -spring variant for your logging configuration.
All the Spring Boot starters depend on spring-boot-starter-logging , which uses Logback by default. For using Log4j2, you need to exclude spring-boot-starter-logging and add spring-boot-starter-log4j2 dependency.
This issue caused by spring use common-logging 1.X ,so if you want to have this logging routed to Log4j 2,you need add dependencies in your pom.xml
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-jcl</artifactId>
<version>2.1</version>
</dependency>
do not remove your common-logging 1.X dependencies
Looking at the dependencies in your pom, you have this one: slf4j-log4j12. This causes log statements against the slf4j api to be routed to the Log4j-1.2 implementation. You probably want these to be routed to the Log4j-2.0 implementation. Can you replace slf4j-log4j12 with log4j-slf4j-impl and try again?
