怎么配置log4j才能让所有log不打到console上能？
现在log文件和console上都打出来了。

------解决方案--------------------
配置log4j.properties

log4j.rootCategory=debug,info,stdout(去掉), R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender（全去掉）
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout（全去掉）

# Pattern to output the caller 's file name and line number.
#log4j.appender.stdout.layout.ConversionPattern=Mis2%p [%t] %C{1}.%M(%L) | %m%n
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p [%c] %m%n（全去掉）

------解决方案--------------------
log4j.rootLogger=info, stdout, file
把info改为warn以上。debug < info < warn < error < fatal
也可以把stdout去掉。

------解决方案--------------------
你可以为package配置统一的日志记录器如：
log4j.logger.org.apache.struts=DEBUG,Console,File
也可以使用一个默认的日志记录器：
log4j.rootLogger=WARN,Console
如果log4j.logger没有配置就使用这个默认的日志记录器，但是所有配置继承此配置(在此基础增加），注意下这个就可以
