在log4j.properties中集成perf4j - 与appender-ref

Question

我正在将log4j整合到log4j.properties ...

log4j.properties

log4j.rootLogger=WARN ,  R

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=/logs/myLogs.log

log4j.appender.R.MaxFileSize=10000KB
log4j.appender.R.MaxBackupIndex=20

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d %-5p [%c] %m%n


log4j.appender.A=org.apache.log4j.RollingFileAppender
log4j.appender.A.File=/logs/myLogs_audit.log
log4j.appender.A.MaxFileSize=100000KB
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=%m%n


log4j.appender.perf=org.apache.log4j.RollingFileAppender
log4j.appender.perf.File=/logs/myLogs_perfStats.log
log4j.appender.perf.Append = true
log4j.appender.perf.MaxFileSize=1024KB
log4j.appender.perf.MaxBackupIndex=20
log4j.appender.perf.layout=org.apache.log4j.PatternLayout
log4j.appender.perf.layout.ConversionPattern=%m%n


log4j.appender.CoalescingStatistics=org.perf4j.log4j.AsyncCoalescingStatisticsAppender
log4j.appender.CoalescingStatistics.TimeSlice=10000

log4j.appender.CoalescingStatistics.appender-ref=perf

log4j.logger.org.perf4j.TimingLogger=info,CoalescingStatistics
log4j.additivity.org.perf4j.TimingLogger=false

错误是：

log4j:WARN No such property [appender-ref] in org.perf4j.log4j.AsyncCoalescingStatisticsAppender.

任何人都可以帮我解决这个问题吗？我不能使用log4j.xml。 性能日志记录未在文件中发布。
