我的要求是将不同的日志写入需要不同模式的控制台。
我已经使用了多个附加器，并且使用了一个单独的记录器，但是它没有采用我为附加器提供的模式，而是采用了另一种模式。
下面是log4j2.properties

name = PropertiesConfig

appenders = console, console1

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss,SSS} %t %-5p %c{6}:%L - %m%n

appender.console1.type = Console
appender.console1.name = STDOUT1
appender.console1.layout.type = PatternLayout
appender.console1.layout.pattern = %m%n

loggers = rolling
logger.rolling.name = org.apache.logging.log4j.core.appender.rolling

#Configure module specific
logger.org.apache.kafka.common.network.Selector = info
logger.com.test.test1 = fine
logger.com.test.test1.service.impl.RSStd=info

#configure rootLogger and attach all the appenders to it
rootLogger.level = info
rootLogger.appenderRef.console.ref = STDOUT

logger.performancelog.name = PERFORMANCE_LOG
logger.performancelog.additivity = false
logger.performancelog.level = info
logger.performancelog.appenderRef.console1.ref = STDOUT1

每次它选择这个模式

appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss,SSS} %t %-5p %c{6}:%L - %m%n

代替

appender.console1.layout.pattern = %m%n

下面是我的java代码GlobalLogger

    /*

    private String lineNumber() {
        StackTraceElement[] threadTrackArray = Thread.currentThread().getStackTrace();
        if (threadTrackArray.length > 3) {
            return ":" + Integer.toString(threadTrackArray[3].getLineNumber()) + "-";
        }
        return "";
    }

    public static void consoleLoggerInit () {
        consoleLoggerInit (null);
    }
    public static void consoleLoggerInit (Level logLevel) {

        final Configuration config = ctx.getConfiguration();
        if (config != null) {
            config.getRootLogger().getAppenders().clear();
            if (logLevel != null) {
                config.getRootLogger().setLevel(logLevel);
            } else {
                config.getRootLogger().setLevel(Level.INFO);
            }
            config.addAppender(ConsoleAppender.createDefaultAppenderForLayout(PatternLayout.newBuilder().withPattern("%5p [%t] (%c{1}) %m%n")
                    .withConfiguration(config).build()));
        }
    }

    public static String validateInput(Object msg) {
        try {
            String aString="";
            if(msg!=null)
                aString=msg.toString();
            return ESAPI.validator().getValidInput(CommonConstants.ESAPI_CONSTANTS.CONTEXT_INPUT_VALIDATION, aString, 
                    CommonConstants.ESAPI_CONSTANTS.VAL_TYPE_SOMETHING_ELSE, aString.length()+1,false);
        } catch (Exception e) {
            return "";
        }
    }
}

我使用this.testLogger=LogManager.getLogger("PERFORMANCE_LOG");和方法

public void logIbgm(Object message){ //1.1
        testLogger.info("(PERFORMANCE_LOG) " + validateInput(message));
    }

PERFORMANCE_LOG is the name that is the same used for the logger name in log4j2.properties

您正在使用appenders和loggers属性指定附加器和记录程序标识符的列表。虽然这些属性仍受支持，但从版本2.6（参见LOG4J2-1308）起不再需要它们。要启用“PERFORMANCE_LOG”记录程序，请执行以下操作之一：

  • 删除loggers属性（默认情况下启用所有记录器ID），
    *或将其设置为所有已启用记录器的列表，例如：
loggers = rolling, performancelog

备注：虽然允许在同一个输出流上有多个appender，但这肯定不是推荐的配置。Log4j2中的PatternLayout支持“模式选择器”（参见文档），可以在您的场景中使用。

使用MarkerPatternSelector的可能解决方案需要：

  • 明显是标记，例如：
private static final Marker PERF_MARKER = MarkerManager.getMarker("PERFORMANCE_LOG");
  • 配置有标记图案选择器的图案布局：
appender.c.l.type = PatternLayout
appender.c.l.mps.type = MarkerPatternSelector
appender.c.l.mps.defaultPattern = %d{yyyy-MM-dd HH:mm:ss,SSS} %t %-5p %c{6}:%L - %m%n
appender.c.l.mps.0.type = PatternMatch
appender.c.l.mps.0.key = PERFORMANCE_LOG
appender.c.l.mps.0.pattern = (%marker) %m%n
  • 要使用PERFORMANCE标记进行日志记录，您可以使用任何日志记录器，只需使用带有标记参数的Logger方法或LogBuilder：
logger.info(PERF_MARKER, () -> validateInput(message));
logger.atInfo()
      .withMarker(PERF_MARKER)
      .log("{}", () -> validateInput(message));
