If using Spring, spring uses LogBack by default so you can create a logback.xml or logback-test.xml in 'main/resources/' or 'test/resources' folder.

You can set log level by package like this:

<configuration>
    <include resource="/org/springframework/boot/logging/logback/base.xml"/>
    <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>
    <root level="error">
        <appender-ref ref="STDOUT"/>
    </root>
    <logger name="com.mypackage" level="debug"/>
    <logger name="com.gargoylesoftware" level="error"/>
</configuration>
