java - logback loading all appenders -

java - logback loading all appenders -

i have logback.xml file 3 appender in : 1 consoleappender , 2 fileappender

<?xml version="1.0" encoding="utf-8"?> <configuration> <appender name="stdout" class="ch.qos.logback.core.consoleappender"> <target>system.out</target> <encoder> <pattern>[%d{yyyy-mm-dd hh:mm:ss}] %msg%m%n%ex</pattern> </encoder> </appender> <appender name="bappender" class="ch.qos.logback.core.fileappender"> <file>logs/b.txt</file> <append>true</append> <encoder> <pattern>[%d{yyyy-mm-dd hh:mm:ss}] -[%t] %-4r %-5p %c : %n%m%n</pattern> </encoder> </appender> <appender name="aappender" class="ch.qos.logback.core.fileappender"> <file>logs/a.txt</file> <append>false</append> <encoder> <pattern>[%d{dd/mm/yyyy : hh:mm:ss} %level - %logger] %m%n</pattern> </encoder> </appender> <logger name="alogger" additivity="false"> <level value="debug" /> <appender-ref ref="aappender" /> </logger> <root level="info"> <appender-ref ref="stdout"/> </root> </configuration>

the problem when launch programme associated alogger(logger logger = loggerfactory.getlogger("alogger");. add together bappend ( , create empty b.txt file ....)

it's logback phone call , execute appender when logger called regardless attached appender. how avoid behaviour ?

thank much

in short, think reply 'no', there isn't way prevent b.txt beingness created. looking @ source fileappender, appears output file (and corresponding parent folder hierarchy) created when appender started (which happens when logback initialized). design deliberate, since approach save considerable time during logging.
