How to disable log messages when spring boot application run?

[Kenan Teymurov]

This is my log4j2.xml file:

 <?xml version="1.0" encoding="UTF-8"?>
    <Configuration status="warn">
        <Properties>
            <Property name="basePath">/folderName/logs/</Property>
        </Properties>
    
        <Appenders>
            <RollingFile name="fileLogger" fileName="${basePath}/fileName.log"
                         filePattern="${basePath}/edf-info-%d{MM-yyyy-dd}.log">
                <PatternLayout>
                    <pattern>%d{MM-yyyy-dd} [%-5level] %l - %msg%n</pattern>
                </PatternLayout>
                <Policies>
                    <TimeBasedTriggeringPolicy interval="1" modulate="true"/>
                </Policies>
            </RollingFile>
            <Console name="console" target="SYSTEM_OUT">
                <PatternLayout>
                    <pattern>%d{MM-yyyy-dd} [%-5level] %l - %msg%n</pattern>
                </PatternLayout>
            </Console>
        </Appenders>
        <Loggers>
            <Logger name="com.company.projectName" level="info" additivity="true">
                <appender-ref ref="fileLogger" level="debug"/>
            </Logger>
            <Root level="info" additivity="false">
                <appender-ref ref="console"/>
            </Root>
        </Loggers>
    </Configuration>

When I used previous versions of Log4j2, only requests sent by my application were being written to my log file in my log folder on my computer. For example:

12-2021-27 [INFO ] com.company.projectname.controller.ClassController.methodName(ClassController.java:21) - paramName1, paramname2
12-2021-27 [INFO ] com.company.projectname.service.ClassServiceImpl.methodName(ClassServiceImpl.java:21) - paramName1, paramname2

But when I switched to the new version of Log4j, because of the vulnerability, before the messages I showed above, when my spring boot project runs, its messages also written. I mean focus on following.

12-2021-22 [INFO ] org.springframework.boot.StartupInfoLogger.logStarting(StartupInfoLogger.java:55) - Starting ProjectNameApplication using Java 1.8.0_111 on pc-name with PID 00000 (C:\Workspace\project-name\target\classes started by user.namein C:\Workspace\project-name)
12-2021-22 [INFO ] org.springframework.boot.SpringApplication.logStartupProfileInfo(SpringApplication.java:635) - No active profile set, falling back to default profiles: default
12-2021-22 [INFO ] org.springframework.boot.StartupInfoLogger.logStarted(StartupInfoLogger.java:61) - Started ProjectNameApplication in 8.858 seconds (JVM running for 12.962)

but I don't want to see these messages in my log file. I just want to write messages when request and response are generated, like before my configuration. How to solve this? I mean I want to only messages to the log file which my requests and responses.

and also this is my pom.xml file

I'm surprised you didn't see this logging before. Your configuration defines a logger for om.company.projectName, but every other logging uses the root logger configuration. That says to log it on info, and that's exactly what you're getting.

If you want to disable this logging, either change the level for the root logger to error or warn, or add a new logger for org.springframework with a level of error or warn to just decrease the Spring (Boot) logging.
