[logback-user] Try to use an evaluator JaninoEventEvaluator in logback. But does not work to filter out depending on condition

17 Mar 2016

      Try to use an evaluator JaninoEventEvaluator in logback. But does not work to
filter out depending on condition.

My configuration of logback.xml is given below.

<appender name="durgaDlyFileSQL" class="ch.qos.logback.core.FileAppender">
<File>${durga.log.file.name.SQL}</File>
<encoder>
<pattern>${ScreenConversionPattern}</pattern>
</encoder>
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator name="loggingTaskEval"
class="ch.qos.logback.classic.boolex.JaninoEventEvaluator">
<expression>
System.out.println("MDC: " + mdc + " " + mdc.get("screenName")); 
String screen = (String) mdc.get("screenName");

    if ((screen == null) ||
    screen.equals("Server Type Entry/Amend/Cancel")) {
    return false;
    }

</expression>
</evaluator>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${durga.log.file.name.SQL}.%d{${finch.log.file.DefaultRolloverFrequency}}</fileNamePattern>
</rollingPolicy>
</appender>

and the output of the log:

[17 Mar 2016 13:42:18.437][Server Type Entry/Amend/Cancel][durga_admin]
TRACE o.h.type.descriptor.sql.BasicBinder 83 binding parameter [3] as

0

I do not want log when screenName = "Server Type Entry/Amend/Cancel"

I'm using janino 2.5.10 and logback 1.1.7 and all the stuff is running on a
tomcat 7.0.47
