[logback-user] Logback Joran Custom Conversion Rule

[Jennifer Donahoe]

I'm trying to create a console appender that uses a custom pattern and a
custom conversion rule to run the logback logs through the DataConverter
class. I can see in the logs that the new conversion rule gets created but
the logs get dropped after that point. I assume some setup in the below
code is not correct but I'm not sure where I'm going wrong.





ConsoleAppender<ILoggingEvent> appender = new ConsoleAppender<>()

appender.setName("consoleAppender")



RuleStore rs = new SimpleRuleStore(context)



Interpreter interpreter = new Interpreter(context, rs, new ElementPath())

InterpretationContext interpretationContext =
interpreter.getInterpretationContext()

interpretationContext.setContext(context)



AttributesImpl attributes = new AttributesImpl()

attributes.addAttribute("","","conversionWord", "", "msgMask")

attributes.addAttribute("","","converterClass", "",
"com.x.logging.library.DataConverter")



ConversionRuleAction conversionRule = new ConversionRuleAction()

conversionRule.setContext(context)

conversionRule.begin(interpretationContext, conversionWord, attributes)



PatternLayoutEncoder encoder = new PatternLayoutEncoder()

encoder.setContext(context)

encoder.setPattern('-%clr(%d{-yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(-%5p)
%clr(-){magenta} %clr(---){faint} %clr([%t]){faint}
%clr(%-40.40logger{39}){cyan} %clr(:){faint} %msgMask(%msg) %n')

encoder.start()



appender.setEncoder(encoder)

appender.setContext(context)

appender.start()



//the appender is later added to the logger



I created a question in StackOverflow about this as well:

Please let me know if you have any examples of this setup or if you can
pinpoint where I’m going wrong.



Thank you,

Jennifer
