LOG4J configuration file configuration Specifies the package information output to the specified file

Search on the internet for more than n data, basic are basic configuration and detailed introduction, reproduced too much, but caused us to search the key information more trouble, after a Google and their own debugging, finally succeeded, recorded.

Suppose I need to output the log information in the Com.domain.web.monitor package to ... /logs/a.log, configure the following

#monitor是我们单独配置的com. The appendname of Domain.web.monitor

Log4j.rootlogger=error,stdout,file,monitor

#这个是为单独的包设置AppendName并且日志级别.

Log4j.logger.com.ct10000.web.monitor=error,monitor

#将所有的日志信息全部输出到后台界面上

Log4j.appender.stdout=org.apache.log4j.consoleappender

log4j.appender.stdout.layout=org.apache.log4j.patternlayouthh:mm:ss}%p[priority]%n%x[ndc]%n%t[thread]%n%c[ category]%n%m[message]%n%n

LOG4J.APPENDER.STDOUT.LAYOUT.CONVERSIONPATTERN=[%5P]%D{YYYY-MM-DD hh:mm:ss}[%c] (%F:%L)%n%m%n%n

#配置com. Domain.web.monitor appendname, output to. In the/logs/a.log.

Log4j.appender.monitor=org.apache.log4j.rollingfileappender

Log4j.appender.monitor.file=.. /logs/a.log

log4j.appender.monitor.maxfilesize=10000kb

log4j.appender.monitor.maxbackupindex=10

Log4j.appender.monitor.append=true

Log4j.appender.monitor.layout=org.apache.log4j.patternlayout

#log4j. appender.monitor.layout.conversionpattern=[start]%d{yyyy/mm/dd/hh:mm:ss}[date]%n%p[priority]%n%x[ndc]%n %t[thread]%n%c[category]%n%m[message]%n%n

LOG4J.APPENDER.MONITOR.LAYOUT.CONVERSIONPATTERN=[%5P]%D{YYYY-MM-DD hh:mm:ss}[%c] (%F:%L)%n%m%n%n

#其余的日志信息输出到. In the/logs/b.log.

Log4j.appender.file.file=.. /logs/b.log

By the way, I recommend several reliable articles on log4j:

Reference: http://blog.csdn.net/ziruobing/archive/2009/02/22/3919501.aspx (slow to open)

Http://dev.firnow.com/course/3_program/java/javajs/20090304/157547.html (detailed explanation of each parameter, feel not all, but enough)

Of course, this is to solve the problem after the record, not a complete tutorial, there are errors hope to guide.
