Log4j2/JPA/Hibernate logging is not working

Question

I can't make hibernate log messages with log4j2. It logs only INFO and WARN. On the other side HikariCP works perfectly with this config. Here is the pom.xml:

    ... <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-slf4j-impl</artifactId>
        <version>2.1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <version>2.1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>2.1</version>
    </dependency> ...

log4j2.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="STDOUT" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{ABSOLUTE} %5p %c{1}:%L - %m%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <!--<Logger name="org.apache.log4j.xml" level="debug"/>-->
        <Root level="info">
            <AppenderRef ref="STDOUT"/>
        </Root>
        <Logger name="org.hibernate" level="debug"/>
        <Logger name="org.hibernate.SQL" level="debug"/>
        <Logger name="com.zaxxer.hikari" level="debug" />
    </Loggers>
</Configuration>

Forgot to mention that hibernate is the latest 4.3.7. It uses jboss logging and according to docs it should work fine with log4j2. — Nenad Dordevic

Hibernate logs with jboss-logging. Now Hibernate 4.3.7.Final uses jboss-logging 3.1.3.GA which does not support any binding with log4j2, BUT its last version (3.2.0.Final) already does, so the only thing you need to do is to add the new one:

<!-- HIBERNATE -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.3.7.Final</version>
</dependency>
<dependency>
    <groupId>org.jboss.logging</groupId>
    <artifactId>jboss-logging</artifactId>
    <version>3.2.0.Final</version>
</dependency>
<!-- HIBERNATE -->
