其它一切配置文件正确，但是就是找不到输出的配置文件，郁闷至极，配置文件如下：
log4j.rootLogger=ERROR log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%m%n log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender #log4j.appender.logfile=org.apache.log4j.RollingFileAppender log4j.appender.logfile.File=C:/szsj.txt log4j.appender.logfile.DatePattern='.'yyyy-MM-dd #log4j.appender.logfile.MaxFileSize=2048KB #log4j.appender.logfile.MaxBackupIndex=10 log4j.appender.logfile.layout=org.apache.log4j.PatternLayout log4j.appender.logfile.layout.ConversionPattern=%d [%p] %c <%t> /n%m%n log4j.logger.com.aaaa=error,stdout,logfile #log4j.logger.org.acegisecurity=info,logfile #log4j.logger.org.springframework=debug,stdout,logfile log4j.logger.org.hibernate.SQL=debug,stdout,logfile
经过仔细查看，竟是文件路径配置错了，应该是：C:/szsj.txt，就可以在C盘找到输出的文件了，郁闷啊。最终配置文件如下：
log4j.rootLogger=ERROR log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%m%n log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender #log4j.appender.logfile=org.apache.log4j.RollingFileAppender log4j.appender.logfile.File=C:/szsj.txt log4j.appender.logfile.DatePattern='.'yyyy-MM-dd #log4j.appender.logfile.MaxFileSize=2048KB #log4j.appender.logfile.MaxBackupIndex=10 log4j.appender.logfile.layout=org.apache.log4j.PatternLayout log4j.appender.logfile.layout.ConversionPattern=%d [%p] %c <%t> /n%m%n log4j.logger.com.cvicse=error,stdout,logfile #log4j.logger.org.acegisecurity=info,logfile #log4j.logger.org.springframework=debug,stdout,logfile log4j.logger.org.hibernate.SQL=debug,stdout,logfile
