问题描述

我试图将日志记录路由到两个不同的文件:一个用于信息消息，另一个用于错误. LevelMatchFilter似乎是正确的方法.不幸的是，所有消息都记录到我的info.log，而不仅仅是信息消息.有什么想法我做错了什么?

这是我的配置:

# Define the root logger with appender file
log4j.logger.com.my.class.ClassName=DEBUG, FILE, ERR, CA

# Define the info file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=info.log
log4j.appender.FILE.filter.a=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.FILE.filter.a.LevelToMatch=INFO
log4j.appender.FILE.filter.a.AcceptOnMatch=true

# Define the layout for info file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%d %-5p %c - %m%n

# Define the error file appender
log4j.appender.ERR=org.apache.log4j.FileAppender
log4j.appender.ERR.File=error.log
log4j.appender.ERR.Threshold=ERROR

# Define the layout for error file appender
log4j.appender.ERR.layout=org.apache.log4j.PatternLayout
log4j.appender.ERR.layout.conversionPattern=%d %-5p %c - %m%n


log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%d %-5p %c - %m%n

我终于在不制作外部XML文件的情况下获得了解决类似问题的解决方案(使用过滤器)，这是结果代码:

log4j.rootLogger=info, R, ERROR

#### only INFO
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=FacturaElectronica.log
log4j.appender.R.MaxFileSize=500KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.R.filter.a=org.apache.log4j.varia.LevelRangeFilter
log4j.appender.R.filter.a.LevelMin=INFO
log4j.appender.R.filter.a.LevelMax=INFO


#### only ERROR
log4j.appender.ERROR=org.apache.log4j.RollingFileAppender
log4j.appender.ERROR.File=FacturaElectronicaError.txt
log4j.appender.ERROR.MaxFileSize=500KB
log4j.appender.ERROR.MaxBackupIndex=1
log4j.appender.ERROR.layout=org.apache.log4j.PatternLayout
log4j.appender.ERROR.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.ERROR.filter.b=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.ERROR.filter.b.LevelToMatch=ERROR
log4j.appender.ERROR.filter.b.AcceptOnMatch=true
log4j.appender.ERROR.Threshold=ERROR

LevelMatchFilter与您的需求无关.

您需要定义2个记录器，一个将具有err appender，另一个将具有文件appender:

log4j.logger.my.info.logger=INFO, FILE
log4j.logger.my.err.logger=ERROR, ERR

和在代码中，您需要在初始化记录器时提供记录器名称:

static Logger logger = Logger.getLogger("my.info.logger");

问题描述

I was trying to route my Logging to two different files: one for INFO messages and another one for ERRORs. LevelMatchFilter seemed the right way to go. Unfortunately, all messages are logged to my info.log, not just the INFO messages. Any ideas what I did wrong?

Here's my config:

# Define the root logger with appender file
log4j.logger.com.my.class.ClassName=DEBUG, FILE, ERR, CA

# Define the info file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=info.log
log4j.appender.FILE.filter.a=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.FILE.filter.a.LevelToMatch=INFO
log4j.appender.FILE.filter.a.AcceptOnMatch=true

# Define the layout for info file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%d %-5p %c - %m%n

# Define the error file appender
log4j.appender.ERR=org.apache.log4j.FileAppender
log4j.appender.ERR.File=error.log
log4j.appender.ERR.Threshold=ERROR

# Define the layout for error file appender
log4j.appender.ERR.layout=org.apache.log4j.PatternLayout
log4j.appender.ERR.layout.conversionPattern=%d %-5p %c - %m%n


log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%d %-5p %c - %m%n

I finally get a solution (using filters) to a similar problem without making an external XML file, here is the resulting code:

log4j.rootLogger=info, R, ERROR

#### only INFO
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=FacturaElectronica.log
log4j.appender.R.MaxFileSize=500KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.R.filter.a=org.apache.log4j.varia.LevelRangeFilter
log4j.appender.R.filter.a.LevelMin=INFO
log4j.appender.R.filter.a.LevelMax=INFO


#### only ERROR
log4j.appender.ERROR=org.apache.log4j.RollingFileAppender
log4j.appender.ERROR.File=FacturaElectronicaError.txt
log4j.appender.ERROR.MaxFileSize=500KB
log4j.appender.ERROR.MaxBackupIndex=1
log4j.appender.ERROR.layout=org.apache.log4j.PatternLayout
log4j.appender.ERROR.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.ERROR.filter.b=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.ERROR.filter.b.LevelToMatch=ERROR
log4j.appender.ERROR.filter.b.AcceptOnMatch=true
log4j.appender.ERROR.Threshold=ERROR

LevelMatchFilter has nothing to do with what you need.

You need to define 2 loggers, one will have the ERR appender and the other the FILE appender:

log4j.logger.my.info.logger=INFO, FILE
log4j.logger.my.err.logger=ERROR, ERR

And in the code you need to provide the logger name when you initialize the logger:

static Logger logger = Logger.getLogger("my.info.logger");
