我创建了一个名为 Project1 的 java 项目。对于这个项目,我创建了一个 log4j.properties 文件。为了在日志文件中写入日志语句,我使用了 DailyRollingFileAppenders。我正在使用 log4j-1.2.16.jar。日志文件是:
log4j.logger.com.gridsense.server.automode=DEBUG, stdout,Rollfile
log4j.rootLogger=off
log4j.logger.com.gridsense.server.automode=debug,Rollfile,stdout
log4j.appender.Rollfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.Rollfile.ImmediateFlush=false
log4j.appender.Rollfile.Append=true
log4j.appender.Rollfile.Threshold=DEBUG
log4j.appender.Rollfile.bufferedIO = true
log4j.appender.Rollfile.File=D:/logs/AutoGS.log
log4j.appender.Rollfile.layout=org.apache.log4j.PatternLayout
log4j.appender.Rollfile.layout.ConversionPattern=[%t] %-5p %c %d{dd/MM/yyyy HH:mm:ss} %m%n
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold=DEBUG
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-4r [%t] %-5p %c %x %m%n
当我运行项目时,我收到以下错误

我不明白有什么问题。
