在.jar Java库中禁用记录器

Question

How to disable logger (print output) of a java library (jar) used in a java program ?

For example i use the jar joda-time-2.8.2.jar

What should I put in my logback.xml file to disable the console output of the jar

logback.xml:

<?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} %-5p %c{1}:%L - %m%n</pattern>
        </encoder>
    </appender>
    <logger name="com.paper.white" additivity="false" level="TRACE">
        <appender-ref ref="stdout" />
    </logger>
    <root level="WARN">
        <appender-ref ref="stdout" />
    </root>
</configuration>

Just create a logger for org.joda.time and set the level to OFF .

<logger name="org.joda.time" level="OFF" >
    <appender-ref ref="stdout"/>
</logger>
