没有项目日志？描述具体一点，如果你要打印到本地日志文件，需要配置log4j.appender.File.File＝路径/文件名

给一个配置作为参考

log4j.rootLogger=info, stdout, file

log4j.logger.org.apache.camel.component.mina=DEBUG, myappender
log4j.logger.org.apache.camel=INFO
log4j.logger.org.apache.camel.impl.DefaultPackageScanClassResolver=INFO

log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.Threshold=DEBUG,INFO
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n 

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.Threshold=info
log4j.appender.file.File=/home/log/info.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern= [%-5p] [%t] %d{yyyy-MM-dd HH:mm:ss} %l %m%n
log4j.appender.file.File.DatePattern='.'yyyy-MM-dd
