Question

I’m making a switch from Log4j to Logback. I’m using HTMLUnit for my project and when I was using Log4j I had to add the 2 lines below to prevent HTMLUnit log messages interfere with my configuration.

log4j.logger.com.gargoylesoftware.htmlunit=ERROR
log4j.logger.org.apache.http=ERROR

Here is my current Logback configuration

<configuration>
    <appender name="DB" class="ch.qos.logback.classic.db.DBAppender">
        <connectionSource
            class="ch.qos.logback.core.db.DriverManagerConnectionSource">
            <driverClass>org.postgresql.Driver</driverClass>
            <url>jdbc:postgresql://MYIP:5432/logs</url>
            <user>logs</user>
            <password>MYPASS</password>
        </connectionSource>
    </appender>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%msg%n</pattern>
        </encoder>
    </appender>

    <root level="DEBUG">
        <appender-ref ref="DB" />
        <appender-ref ref="STDOUT" />
    </root>

</configuration>

I’m now using an xml style configuration file for Logback. What is the equivalent of the lines above for the xml Logback configuration?

You can explicitly specify the level of loggers in the logback configuration like so:

<logger name="com.gargoylesoftware.htmlunit" level="ERROR" />
<logger name="org.apache.http" level="ERROR" />
