重复的日志条目log4j

Question

我在日志文件中收到重复的条目.已经附加了我的log4j.properties.

log4j.properties:

###############################################################################
# log4j Configuration file: Defines following loggers
# SL    -   Standard root Logger
# EL    -   Error Logger with the threshold level explicitly set to ERROR
# DL    -   Data base logger - to log db queries separately
# BL    -   Batch logger
###############################################################################

log4j.rootLogger=TRACE,SL,EL
log4j.rootLogger.additivity=false

#Standard Log
log4j.appender.SL=org.apache.log4j.DailyRollingFileAppender
log4j.appender.SL.File=${log.file}/log.log
log4j.appender.SL.layout=org.apache.log4j.PatternLayout
log4j.appender.SL.layout.ConversionPattern=[%5p] [%t %d{HH:mm:ss:SSS}] [%X{sessionId}:%X{hostId}:%X{userId}] (%F:%M:%L) %m%n

#Error Log
log4j.appender.EL=org.apache.log4j.DailyRollingFileAppender
log4j.appender.EL.File=${log.file}/error.log
log4j.appender.EL.layout=org.apache.log4j.PatternLayout
log4j.appender.EL.Threshold=ERROR
log4j.appender.EL.layout.ConversionPattern=[%5p] [%t %d{HH:mm:ss:SSS}] [%X{sessionId}:%X{hostId}:%X{userId}] (%F:%M:%L) %m%n

# Database Log
log4j.logger.org.springframework.jdbc=DEBUG,DL

log4j.appender.DL=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DL.File=${log.file}/db.log
log4j.appender.DL.layout=org.apache.log4j.PatternLayout
log4j.appender.DL.layout.ConversionPattern=[%5p] [%t %d{HH:mm:ss:SSS}] [%X{sessionId}:%X{hostId}:%X{userId}] (%F:%M:%L) %m%n

#Forecast Log
log4j.appender.MAPS_FC=org.apache.log4j.DailyRollingFileAppender
log4j.appender.MAPS_FC.File=${log.file}/forecast.log
log4j.appender.MAPS_FC.layout=org.apache.log4j.PatternLayout
log4j.appender.MAPS_FC.layout.ConversionPattern=[%5p] [%t %d{HH:mm:ss:SSS}] [%X{sessionId}:%X{hostId}:%X{userId}] (%F:%M:%L) %m%n

#Logger configuration
log4j.logger.com.singaporeair.maps=TRACE,SL,EL
log4j.logger.com.singaporeair.maps.app.service.impl.gantt=DEBUG,MAPS_FC
log4j.logger.com.singaporeair.maps.app.dao.impl.gantt=DEBUG,MAPS_FC

在上面配置的log.log文件中获取dulicate条目.

日志提取:

[ INFO] [SimpleAsyncTaskExecutor-9 19:04:00:800] [::] (AppProfiler.java:doProfile:69) Processing Time(ms): BaseDAOImpl: getBatchDetails: 63

请帮忙

Answer 1

如果关闭可加性,则作为父项子项的记录器不会导致双重记录.例如:

#Logger configuration
log4j.logger.com.singaporeair.maps=TRACE,SL,EL
log4j.additivity.com.singaporeair.maps=false

log4j.logger.com.singaporeair.maps.app.service.impl.gantt=DEBUG,MAPS_FC
log4j.additivity.com.singaporeair.maps.app.service.impl.gantt=false

log4j.logger.com.singaporeair.maps.app.dao.impl.gantt=DEBUG,MAPS_FC
log4j.additivity.com.singaporeair.maps.app.dao.impl.gantt=false

Answer 2

com.singaporeair.mapscom.singaporeair.maps.app.service.impl.gantt是和的超集com.singaporeair.maps.app.dao.impl.gantt

所有匹配的内容com.singaporeair.maps.app.dao.impl.gantt也将匹配com.singaporeair.maps，这将产生 2 个日志实体。

猜测 1：您需要关闭追加器继承。看来这是错误的。

猜测 2：根记录器和 com.singaporeair.maps 都记录到 SL 和 EL 附加程序。这只是一个猜测，但尝试改变它：

log4j.logger.com.singaporeair.maps=TRACE,SL,EL

对此：

log4j.logger.com.singaporeair.maps=TRACE
