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: https://stackoverflow.com/q/66768278/7371030?sem=2 Please let me know if you have any examples of this setup or if you can pinpoint where I’m going wrong.
