logback_LevelPatternLayout

Special PatternLayout where formatting patterns can be specified per level

Example logback.xml:

<configuration scan="true" debug="true">
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
            <layout class="pack.LevelPatternLayout">
                <defaultPattern>DEFAULT PATTERN %c - %m\n</defaultPattern>
                <debugPattern>DEBUG PATTERN %c - %m\n</debugPattern>
            </layout>
        </encoder>
    </appender>
    
    <root level="DEBUG">
        <appender-ref ref="CONSOLE" />
    </root>
</configuration>

Test code:

Logger log = LoggerFactory.getLogger(TestStart.class);

@Test
public void test() throws Exception{
    log.debug("some debug level log");
    log.info("some info level log");
    log.error("some error level log");
}

Output:

DEBUG PATTERN pack.TestStart - some debug level log
DEFAULT PATTERN pack.TestStart - some info level log
DEFAULT PATTERN pack.TestStart - some error level log
