How do I disable logging from javers?

Answer 1

You can set log level for Javers in logback.xml like this :

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="org.javers.SQL" level="DEBUG"/>

    <root level="info">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

With this configuration you should only see DEBUG log messages displayed in pattern above.

If you want to completly disable logging you can use this :

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="org.javers.SQL" level="OFF"/>

    <root level="info">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

The instruction: level="OFF" tells Logback to disable all log output for a given logger, in your case that is javers logger.

In Spring Boot, you can set the logging level in the application.properties file.

For example (if you only want WARN or above):

logging.level.org.javers=WARN
