How to stop hibernate excessive logging?

Question

My application uses hibernate and its printing lot of logging. I tried to set logging to error level as below. However, it does not set hibernate logging to error level. Is anything missing here?

pom.xml :

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.11.2-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.11.2-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-jul</artifactId>
    <version>2.11.2</version>
</dependency>

log4j2.xml

    <?xml version="1.0" encoding="UTF-8"?>

<Configuration status="INFO">

    <Appenders>
        <Console name="CONSOLE" target="SYSTEM_OUT">
            <PatternLayout
                pattern="[%d{dd MMM yyyy HH:mm:ss}] [%-5p] [%t] [%C{1}:%M:%L] - %m%n" />
        </Console>
    </Appenders>

    <Loggers>
        <Logger name="com.myapp" level="error" additivity="false">
            <AppenderRef ref="CONSOLE" />
        </Logger>
        <Root level="info">
            <appender-ref ref="CONSOLE" />
        </Root>
        <Logger name="org.hibernate" level="error" additivity="false">
            <AppenderRef ref="CONSOLE" />
        </Logger>

    </Loggers>

</Configuration>

Hibernate and spring version used :

<spring-framework.version>4.0.3.RELEASE</spring-framework.version>
        <hibernate.version>3.6.9.Final</hibernate.version>

Log its printing

The thread names seem to suggest that you're running on a weblogic container. Are you sure that the logging config is being used at all? (e.g. see log4j2-not-working-in-weblogic-12-2-1).

Apart from that, I also don't see the point in using additivity="false" and then repeating exactly the same appenders. Why don't you prefer something simpler like this?

<Loggers>
    <Root level="info">
        <appender-ref ref="CONSOLE" />
    </Root>
    <Logger name="com.myapp" level="error"/>
    <Logger name="org.hibernate" level="error"/>
</Loggers>

Is it a Spring application if so you could hide SQL from printing via properties file option:

spring.jpa.show-sql=false

If it is not a Spring you could try this (in Sprint apllication such Hibernate log config works):

<Logger name="org.hibernate.SQL" level="error"/>
<Logger name="org.hibernate.type" level="error"/>

OR whatever Log Level do you want.

What seems that your logger is not picking the right file configuration, there might be two reasons.

You did not specify your log4j2.xml file path correctly, as your project is not picking it right, which is detected from your logs.
Your log4j2.xml file has some error in appender reference tag inside root tag, change appender-ref to AppenderRef

<Root level="info">
     <appender-ref ref="CONSOLE" />
</Root>

to

<Root level="info">
      <AppenderRef ref="CONSOLE" />
</Root>

The above two identified reasons are from the logging pattern you are using in your log4j2.xml and actual logs shared are totally different. Look your desired pattern layout from log4j2.xml

<PatternLayout pattern="[%d{dd MMM yyyy HH:mm:ss}] [%-5p] [%t] [%C{1}:%M:%L] - %m%n" />

It should print logs looks like

[16 Apr 2020 19:05:16.733] [...] [...] [...:...:...] - .......

where actual logs have different patterns.

19:05:16.733 [...] ... ....... - .....

as mentioned under.

19:05:16.733 [[ACTIVE] ExecuteThread: '18' for queue: 'weblogic.kernel.Default (self-tuning)'] DEBUG org.hibernate.hql.ast.ErrorCounter - throwQueryException() : no errors
19:05:16.734 [[ACTIVE] ExecuteThread: '18' for queue: 'weblogic.kernel.Default (self-tuning)'] DEBUG o.h.hql.ast.QueryTranslatorImpl - HQL: SELECT g FROM myClass g
19:05:16.734 [[ACTIVE] ExecuteThread: '18' for queue: 'weblogic.kernel.Default (self-tuning)'] DEBUG o.h.hql.ast.QueryTranslatorImpl - SQL: sql sample
