Different log appenders use the different log level for the same java package?

here is my java logback configuration:

<?xml version="1.0" encoding="UTF-8"?>
  <configuration>
<appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
    <encoder charset="UTF-8">
        <pattern>%d{yyyy-MM-dd HH:mm:ss} %-5level %msg%n></pattern>
    </encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <encoder charset="UTF-8">
        <pattern>%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{36} - %msg%n
        </pattern>
    </encoder>
</appender>
    <logger name="org.apache.zookeeper"  additivity="false">  
     <appender-ref ref="stdout"/>  
   </logger>
   <logger name="com.hazelcast"  additivity="false">  
      <appender-ref ref="stdout"/>  
 </logger>  
<root level="INFO">
    <appender-ref ref="FILE" />
</root>

what i want to do here is: I have two log appenders: one for console,and another for log file; But for the same java package(for example：org.apache.zookeeper) I want use two different log level,INFO for file appender and ERROR for condole; But my log configuration upside doesn't work right. Can anyone figure out my errors or some solutions?

Since the log level per Java package can only be defined globally, you may use a ThresholdFilter to filter all levels below ERROR in your console appender.

you can just block them:

    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">  
        <evaluator>   
            <expression>logger.contains("zookeeper") || logger.contains("hazelcast")    </expression>  
        </evaluator>  
        <OnMismatch>ACCEPT</OnMismatch>  
        <OnMatch>DENY</OnMatch>  
    </filter>
