log4j:WARN在org.apache.log4j.RollingFileAppender中没有这样的属性[conversionPattern] [英] log4j:WARN No such property [conversionPattern] in org.apache.log4j.RollingFileAppender

问题描述

有人可以帮助我解决此错误消息.我不知道为什么我的应用程序总是显示这些警告

Can someone help me with this error message. I don't know why my application is always showing these warning

log4j:WARN No such property [conversionPattern] in org.apache.log4j.RollingFileAppender.

我的应用程序是一个简单的休眠项目

My application is a simple hibernate project

这是完整的属性文件

# Root logger option
log4j.rootLogger=DEBUG, A1

# Direct log messages to a log file  
log4j.appender.A1=org.apache.log4j.RollingFileAppender
log4j.appender.A1.File=logs/HibernateAnnotation.log 
log4j.appender.A1.MaxFileSize=1MB
log4j.appender.A1.MaxBackupIndex=1
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n 

# Log everything. Good for troubleshooting  
log4j.logger.org.hibernate=warn  

推荐答案

log4j.appender.A1.ConversionPattern =％d {ABSOLUTE}％5p％c {1}:％L-％m％n

log4j.appender.A1.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

应该是log4j.appender.A1.layout.ConversionPattern，而不是log4j.appender.A1.ConversionPattern1.
