spring diasable logging for controller

Question

There is a polling service which fills up my log

2022-01-09T05:24:32,827 DEBUG [ajp-nio-8009-exec-7] o.s.c.l.LogFormatUtils: GET "/VenusD/anonymous/

Somewhat like above. I just need to disable spring logging for a selected controller or request mapping.

What is the right way of doing it? How can I probably exclude it?

If you don't have to change log level of package, comment please.

You can set log level of pacakge.

My log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="console" target="SYSTEM_OUT">
            <PatternLayout
                pattern="[%d{yyyy-MM-dd HH:mm:ss}:%-3relative][%thread] %-5level %logger{100}.%M - %msg%n" />
        </Console>
    </Appenders>
    
    <Loggers>
        <Root level="DEBUG" additivity="false">
            <AppenderRef ref="console" />
        </Root>
        
        <!-- <Logger name="org.springframework.web.servlet.DispatcherServlet" level="warn"></Logger>  -->
    </Loggers>

    
</Configuration>

My log, When I set log levl debug

My log, When I remove following comment in log4j2.xml

<!-- <Logger name="org.springframework.web.servlet.DispatcherServlet" level="warn"></Logger>  --> 
to
<Logger name="org.springframework.web.servlet.DispatcherServlet" level="warn"></Logger>

Debug log level of org.springframework.web.servlet.DispatcherServlet is removed.
