Log4j2 disable console on production
0
I'm developing a Web app and I'm using log4j2. In developing mode, I'm logging using RollingFile and Console appenders.
Everything is working properly, but I'd want to disable the Console appender when my project will be released and it will be in production mode.
Here's a slice of my log4j2.xml code:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="PropertiesConfig" packages="com.project.application">
<!-- PROPERTIES -->

<Property name="consolePattern">%highlight{[%-5level] [%d{yyyy-MM-dd HH:mm:ss,SSS}] [%c{1}] - %msg%n}</Property>
<Property name="rollingFilePattern">[%-5level] [%d{yyyy-MM-dd HH:mm:ss,SSS}] [%c{1}] - %msg%n</Property>
</Properties>

</PatternLayout>

Thank you!

Use a filter, e.g. ThreadContextMapFilter:
<Console name="Console" target="SYSTEM_OUT" immediateFlush="true">
<ThreadContextMapFilter onMatch="DENY" onMismatch="NEUTRAL">
<KeyValuePair key="is-production" value="1"/><!-- skip on production -->
</ThreadContextMapFilter>
<PatternLayout>
<pattern>${consolePattern}</pattern>
</PatternLayout>
</Console>
The initialization of the ThreadContext entry can be perfomed in a ServletContextListener, e.g.:
@WebListener
public class Log4jThreadContextInitializer implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
String isProduction = isProduction() ? "1" : "0";
sce.getServletContext().log("Setting 'is-production' flag for Log4j to " + isProduction);
org.apache.logging.log4j.ThreadContext.put("is-production", isProduction);
}
private boolean isProduction() {
// TODO: production detection
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
}

Thank you very much! Some questions: can I set the value in the xml as "1" or "0" directly and nothing else? Why the initialization in the ServletContextListener?
– Ommadawn
Nov 20 '18 at 14:15
@Ommadawn But if you were to set the value in the XML (I don't even know if it's at all possible), how would you detect whether it is production or not? Perhaps, you'd need a differentlog4j2.xmlfor production then. Note that the code inlog4j2.xmlthat I posted does not set anything - it only tests if the value is set to"1"or not.

@Ommadawn Yes, if you setis-productionto1inThreadContext, Log4j2 will skip the console appender (because theThreadContextMapFilteris configured asonMatch="DENY", meaning it skips the appender if the condition matches).
