log4j logging file exclude logs messages

I am building spring boot application version 2.0.2.RELEASE with BOM Finchley.RC2 and trying to write logs to file in using log4j2.xml . The problem is i want to log only my application messages like:

log.error("this is error");
log.info("this is info");

but the log file is showing other logs as well like Spring logs etc as below:

29-08-2018 18:01:45,023 [INFO ] [] [main] - this is info
29-08-2018 18:01:45,492 [INFO ] [] [main] - Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@b4711e2: startup date [Wed Aug 29 18:01:45 PKT 2018]; root of context hierarchy
29-08-2018 18:01:45,659 [INFO ] [] [main] - JSR-330 'javax.inject.Inject' annotation found and supported for autowiring
29-08-2018 18:01:45,687 [INFO ] [] [main] - Bean 'configurationPropertiesRebinderAutoConfiguration' of type [org.springframework.cloud.autoconfigure.ConfigurationPropertiesRebinderAutoConfiguration$$EnhancerBySpringCGLIB$$af5d2aa2] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

How I can customize my log4j2.xml to acheive only my application logging for info/debug/error logs. Below is my log4j2.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
  <Appenders>
    <RollingFile name="FileAppender" fileName="mylogFile.log" 
        append="true" filePattern="log-%d{MM-dd-yyyy}-%i.log">
      <PatternLayout>
        <pattern>%d{dd-MM-yyyy HH:mm:ss,SSS} [%-5p] [%X{X-B3-TraceId}] [%t] - %m%n</pattern>
      </PatternLayout>
      <Policies>
        <TimeBasedTriggeringPolicy />
        <SizeBasedTriggeringPolicy size="250 MB"/>
      </Policies>
      <DefaultRolloverStrategy max="20"/>
    </RollingFile>
    <Console name="STDOUT" target="SYSTEM_OUT">
      <PatternLayout pattern="%d{dd-MM-yyyy HH:mm:ss,SSS} [%-5p] [%X{X-B3-TraceId}] [%t] - %m%n"/>
    </Console>
    <File name="JSONAppender" fileName="\\tmp\\logFile.json.log" append="true">

    <JSONLayout complete="true" charset="UTF-8" compact="true" eventEol="true"/>

    </File>
  </Appenders>
  <Loggers>
    <Logger name="org.apache.logging.log4j.core.config.xml" level="info" >
      <AppenderRef ref="FileAppender"/>
    </Logger>
    <Logger name="guru.springframework.blog.log4j2json" level="debug">
      <AppenderRef ref="JSONAppender"/>
    </Logger>


    <Root level="info">
      <AppenderRef ref="STDOUT" />
      <AppenderRef ref="FileAppender"/>
      <AppenderRef ref="JSONAppender"/>
    </Root>
  </Loggers>
</Configuration>`

Any help please what is wrong with my configration? With Spring 1.5.9 version it was working fine but as i upgrade to 2.0.2.RELEASE logging to file not working.

In order to avoid INFO from external libraries you need to adjust the root log level from INFO to WARN or ERROR.

In addition you have to create an explicit logger for the packages/classes you want to write log messages from.

<Logger name="com.my.app" level="info">
  <AppenderRef="STDOUT" />
  ..
</Logger>

I would also recommend that you add the logger (%c) to the log pattern.
