log4j config when testing to show only Errors

Question

I have a Spring application, where I use eclipselink and dbunit for my tests I've created this log4j.xml file on /src/test/resources/

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true"
        xmlns:log4j='http://jakarta.apache.org/log4j/'>

    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern"
                    value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
        </layout>
    </appender>

    <root>
        <level value="ERROR" />
        <appender-ref ref="console" />
    </root>

</log4j:configuration>

But when i run the tests I see a lot of messages in the console, not only the error ones:

this is my /src/test/java/META-INF/persistence.xml file:

and in my maven pom.xml:

<properties>

    <eclipselink.logging.level.sql>OFF</eclipselink.logging.level.sql>
</properties>

Answer 1

The wiki: wiki.eclipse.org/EclipseLink/Examples/JPA/Logging describes logging in EclipseLink. I this case, it seems you are on Weblogic server (as determined by the Configured server platform WebLogicPlatform log message), and if using container managed persistence, it is likely injecting its own logger into the persistence unit - you would need to use the WebLogic console to change the logging settings.

You can prevent this by adding:

 <property name="eclipselink.logging.logger" value="DefaultLogger"/>

To the persistence.xml, which will have EclipseLink use its own logging, which will use the settings you have already configured.

Answer 2

The log level configuration is included in the definition of the persistence unit in the persistence.xml ,

add this:

<property name="eclipselink.logging.level" value="OFF"/>
        <property name="eclipselink.logging.parameters" value="false"/>
        <property name="eclipselink.weaving" value="static" />
        <property name="eclipselink.logging.level.sql" value="OFF" />
        <property name="eclipselink.logging.level.cache" value="OFF" />
