这篇文章中的log4j.properties可能会帮助您寻找所需内容。 http://ta.cnci.org/more-about-java/35-java-blogs/238-dailyfileappender可能你可以使用我之前写过的DailyFileAppender.java。这个想法很简单，分为4个部分：

设置log4j.rootCategory以包含“FILE DEF”
定义您的“文件DEF”，例如log4j.appender.SOADAILY
告诉记录器将其过滤到“FILE DEF”：log4j.logger.com.incresearch.soa.db = DEBUG，TDLDAILY
告诉记录器不要从其他地方删除：log4j.additivity.org.cnci.tdl = false

但这是一个例子：


    #------------------------------------------------------------------------------
    #  Default log4j.properties file.  This should be in the LocalFiles folder
    #
    #    Possible Log Levels:
    #      FATAL, ERROR, WARN, INFO, DEBUG
    #
    log4j.rootCategory=DEBUG, SOADAILY, TDLDAILY
    log4j.logger.org.apache=ERROR

    #------------------------------------------------------------------------------
    #  The following properties configure the Daily Rolling File appender.
    #  For SOA components, mostly from org.cnci.soa.* packages
    #------------------------------------------------------------------------------
    log4j.appender.SOADAILY = org.cnci.util.DailyFileAppender
    log4j.appender.SOADAILY.File = logs/SOAServices.log
    log4j.appender.SOADAILY.MaxLogs = 30
    log4j.appender.SOADAILY.Append = true
    log4j.appender.SOADAILY.DatePattern = '.'yyy-MM-dd
    log4j.appender.SOADAILY.layout = org.apache.log4j.PatternLayout
    log4j.appender.SOADAILY.layout.ConversionPattern = %d %5p %c{1}:%L - %m%n

    #------------------------------------------------------------------------------
    #  The following properties configure the Daily Rolling File appender for TDL.
    #  For TDL applications, mostly from org.cnci.tdl.* packages and jboss seams, richfaces...
    #------------------------------------------------------------------------------
    log4j.appender.TDLDAILY = org.apache.log4j.FileAppender
    log4j.appender.TDLDAILY.File = logs/TDLServices.log
    log4j.appender.TDLDAILY.MaxLogs = 30
    log4j.appender.TDLDAILY.Append = true
    log4j.appender.TDLDAILY.DatePattern = '.'yyy-MM-dd
    log4j.appender.TDLDAILY.layout = org.apache.log4j.PatternLayout
    log4j.appender.TDLDAILY.layout.ConversionPattern = %d %5p %c{1}:%L - %m%n


    # Extracting all Adapter logging into it own file
    log4j.logger.org.cnci.soa=DEBUG, SOADAILY
    log4j.additivity.org.cnci.soa=false
    log4j.logger.com.hazelcast=ERROR, SOADAILY
    log4j.additivity.com.hazelcast=false
    log4j.logger.org.opensaml=ERROR, SOADAILY
    log4j.additivity.org.opensaml=false

    # Extracting all DB (TDL) logging into it own file 
    log4j.logger.com.incresearch.soa.db=DEBUG, TDLDAILY
    log4j.additivity.org.cnci.tdl=false
    log4j.logger.org.jboss.seam=ERROR, DAILY
    log4j.additivity.org.jboss.seam=false
    log4j.logger.org.richfaces=ERROR, DAILY
    log4j.additivity.org.richfaces=false
    log4j.logger.org.ajax4jsf=ERROR, DAILY
    log4j.additivity.org.ajax4jsf=false

在这里查看我的答案：Log4j to write json array to disk

它显示了如何将com.foo.bar日志发送到console，com.example到文件appender;你可以混合搭配 - 基本上是log4j.com之后的包名。 part将为根植于那里的类的子树创建一个新的记录器;如果在后代包中你需要更改位置（记住，默认情况下appenders是添加的）你必须将'inherit'设置为'false'。

使用log4j实现多个日志位置的最佳方法是什么？
