logback のログ開始を抑制

Java

logback のログ出力で最初に以下の余計なログが出力される場合の抑制

13:29:48,061 |-INFO in ch.qos.logback.classic.LoggerContext[default] - This is logback-classic version 1.4.6

logback のマニュアル：Chapter 3: Logback configuration　に書いてあるのですが、
https://logback.qos.ch/manual/configuration.html#logback.statusLC
これを出力しないようにするには statusListener に NopStatusListener を割り当てます。
以下のように、logback.xml　で、<configuration> に、
　<statusListener class="ch.qos.logback.core.status.NopStatusListener" />
を記述します。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE logback>
<configuration>
<statusListener class="ch.qos.logback.core.status.NopStatusListener" />

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
	<Target>System.out</Target>
	<encoder>
		<Pattern>%-23d{yyyy/MM/dd HH:mm:ss.SSS} %-5p [%thread][%class#%method]%m%n</Pattern>
	</encoder>
</appender>
<appender name="STDOUT_DEBUG" class="ch.qos.logback.core.ConsoleAppender">
	<Target>System.out</Target>
	<encoder>
		<Pattern>%-23d{yyyy/MM/dd HH:mm:ss.SSS} %-5p [%thread][%class#%method:%line]%m%n</Pattern>
	</encoder>
</appender>

<logger name="org.sample">
	<level value="debug" />
	<appender-ref ref="STDOUT" />
</logger>

</configuration>
