自定义日志级别的 log4j Appender 可加性

Question

我有一个场景，我有一个单独的自定义级别定义 XYZLogLevel 用于日志记录，并且我有 2 个滚动文件附加程序，其中第二个附加程序专门保留用于记录来自 XYZLogLevel 的日志消息。然而，这两个文件中的日志都是不可取的。

注意：-

1. 日志不是特定于包的，因此不会为包添加可加性 工作。
2. 一切都必须通过log4j.properties 文件完成。

将 LevelRangeFilter 添加到第一个 appender 可以部分解决它，但是 当我为另一个自定义级别添加第三个附加程序时，我再次看到 第二个和第三个附加程序中的重复。

log4j.rootCategory=ERROR, F, XYZLOG, LMNLOG

log4j.appender.F=org.apache.log4j.RollingFileAppender
log4j.appender.F.File=f_log.log
log4j.appender.F.MaxFileSize=5MB
log4j.appender.F.MaxBackupIndex=10
log4j.appender.F.layout = org.apache.log4j.PatternLayout
log4j.appender.F.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss.SSS} %c{1} [%p] %m%n

log4j.appender.XYZLOG=org.apache.log4j.RollingFileAppender
log4j.appender.XYZLOG.File=xyz_reporting.log
log4j.appender.XYZLOG.threshold=XYZLOG#com.services.domain.xyzlogs.XYZLogLevel
log4j.appender.XYZLOG.filter.a=org.apache.log4j.varia.LevelMatchFilter    
log4j.appender.XYZLOG.filter.a.LevelToMatch=XYZLOG#com.services.domain.xyzlogs.XYZLogLevel
log4j.appender.XYZLOG.filter.a.AcceptOnMatch=true 
log4j.appender.XYZLOG.MaxFileSize=100KB
log4j.appender.XYZLOG.MaxBackupIndex=10
log4j.appender.XYZLOG.layout=org.apache.log4j.PatternLayout
log4j.appender.XYZLOG.layout.ConversionPattern=%m%n

log4j.appender.LMNLOG=org.apache.log4j.RollingFileAppender
log4j.appender.LMNLOG.File=lmn_reporting.log
log4j.appender.LMNLOG.threshold=LMNLOG#com.services.domain.lmnlogs.LMNLogLevel
log4j.appender.LMNLOG.filter.a=org.apache.log4j.varia.LevelMatchFilter    
log4j.appender.LMNLOG.filter.a.LevelToMatch=LMNLOG#com.services.domain.lmnlogs.LMNLogLevel
log4j.appender.LMNLOG.filter.a.AcceptOnMatch=true 
log4j.appender.LMNLOG.MaxFileSize=100KB
log4j.appender.LMNLOG.MaxBackupIndex=10
log4j.appender.LMNLOG.layout=org.apache.log4j.PatternLayout
log4j.appender.LMNLOG.layout.ConversionPattern=%m%n

也许这可以通过org.apache.log4j.varia.DenyAllFilter 解决，但不知何故我无法为属性文件配置它。我相信该功能仅适用于 XML 配置。

这是一个非常棘手的情况，因为我无权切换到 XML 配置，任何对此的帮助将不胜感激。 链接和示例会很棒，因为我很快就能理解它们。

I am answering my own question.

First you need to create a logger and set additivity as FALSE.

log4j.logger.XZYLOG=XZYLOG#XYZLOG#com.services.domain.xyzlogs.XYZLogLevel, XYZAPPENDER

log4j.additivity.XZYLOG=false

log4j.logger.LMNLOG=LMNLOG#XYZLOG#com.services.domain.lmnlogs.LMNLogLevel, LMNAPPENDER

log4j.additivity.LMNLOG=false

Then configure the appenders in following way.

log4j.appender.XYZLOGAPPENDER=org.apache.log4j.RollingFileAppender
log4j.appender.XYZLOGAPPENDER.File=xyz_reporting.log
log4j.appender.XYZLOGAPPENDER.threshold=XYZLOG#com.services.domain.xyzlogs.XYZLogLevel
log4j.appender.XYZLOGAPPENDER.MaxFileSize=100KB
log4j.appender.XYZLOGAPPENDER.MaxBackupIndex=10
log4j.appender.XYZLOGAPPENDER.layout=org.apache.log4j.PatternLayout
log4j.appender.XYZLOGAPPENDER.layout.ConversionPattern=%m%n

log4j.appender.LMNLOGAPPENDER=org.apache.log4j.RollingFileAppender
log4j.appender.LMNLOGAPPENDER.File=lmn_reporting.log

log4j.appender.LMNLOGAPPENDER.threshold=LMNLOG#com.services.domain.lmnlogs.LMNLogLevel
log4j.appender.LMNLOGAPPENDER.MaxFileSize=100KB log4j.appender.LMNLOGAPPENDER.MaxBackupIndex=10 log4j.appender.LMNLOGAPPENDER.layout=org.apache.log4j.PatternLayout log4j.appender.LMNLOGAPPENDER.layout.ConversionPattern=%m%n

You may or may not need the filter in this case.

Note: I cannot post company code here thats why I modified the solution.
This is to give you general idea how I have solved this problem.
