我尝试为自定义日志级别实现levelmatchfilter，并在属性文件中对其进行配置。 使用chrunchify loglevel的模板创建我的： http://crunchify.com/java-how-to-create-your-own-logging-level-in-log4j-configuring-log4j/
配置我的属性文件如下：
log4j.rootLogger.level=DEBUG
# LOG4J daily rolling log files configuration
log4j.rootLogger=debug, DebugAppender, InfoAppender, ErrorAppender, ChangeAppender
#DebugAppender (Debug)
log4j.appender.DebugAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DebugAppender.File=./log/debug/ngpmt_debug.log
log4j.appender.DebugAppender.DatePattern='.'yyyy-MM-dd
log4j.appender.DebugAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.DebugAppender.layout.ConversionPattern=[%p] %d %c %M - %m%n
log4j.appender.DebugAppender.Threshold=DEBUG
#InfoAppender (Loud)
log4j.appender.InfoAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.InfoAppender.File=./log/loud/ngpmt_info.log
log4j.appender.InfoAppender.DatePattern='.'yyyy-MM-dd
log4j.appender.InfoAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.InfoAppender.layout.ConversionPattern=[%p] %d %c %M - %m%n
log4j.appender.InfoAppender.Threshold=INFO
#ErrorAppender (Silent)
log4j.appender.ErrorAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ErrorAppender.File=./log/silent/ngpmt_error.log
log4j.appender.ErrorAppender.DatePattern='.'yyyy-MM-dd
log4j.appender.ErrorAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.ErrorAppender.layout.ConversionPattern=[%p] %d %c %M - %m%n
log4j.appender.ErrorAppender.Threshold=WARN
#ChangeAppender (Changes)
log4j.appender.ChangeAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ChangeAppender.File=./log/silent/ngpmt_changes.log
log4j.appender.ChangeAppender.File.filter.a=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.ChangeAppender.File.filter.a.LevelToMatch=CHANGE#at.xtention.pqm.ngpmt.gui.helpers.Change
log4j.appender.ChangeAppender.File.filter.a.AcceptOnMatch=true
log4j.appender.ChangeAppender.DatePattern='.'yyyy-MM-dd
log4j.appender.ChangeAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.ChangeAppender.layout.ConversionPattern=[%p] %d %c %M - %m%n
我有3个不同范围的日志文件。除此之外，我想要一个只记录CHANGE-Level消息的日志文件。
