RootLogger輸出不同層次不同的文件

我想有log4j的輸出INFO級別info.log建立和調試水平的debug.log，使之與這段代碼：RootLogger輸出不同層次不同的文件

logger.info("This is an info message"); 
logger.debug("This is a debug message");

只有第一個會去info.log，而兩者都會去debug.log。

這不起作用：

log4j.rootLogger=INFO, R, T 

# A1 is set to be a ConsoleAppender. 
log4j.appender.A1=org.apache.log4j.ConsoleAppender 

# A1 uses PatternLayout. 
log4j.appender.A1.layout=org.apache.log4j.PatternLayout 
log4j.appender.A1.layout.ConversionPattern=%r %-5p %c %x - %m%n 

log4j.appender.R=org.apache.log4j.FileAppender 
log4j.appender.R.File=info.log 
log4j.appender.R.layout=org.apache.log4j.PatternLayout 
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n 
log4j.appender.R.Threshold = INFO 

log4j.appender.T=org.apache.log4j.FileAppender 
log4j.appender.T.File=debug.log 
log4j.appender.T.layout=org.apache.log4j.PatternLayout 
log4j.appender.T.layout.ConversionPattern=%p %t %c - %m%n 
log4j.appender.T.Threshold = DEBUG

無論是做這個的：

log4j.rootLogger=INFO, R 
log4j.rootLogger=DEBUG, T 

log4j.appender.R=org.apache.log4j.FileAppender 
log4j.appender.R.File=info.log 
log4j.appender.R.layout=org.apache.log4j.PatternLayout 
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n 
log4j.appender.R.Threshold = INFO 

log4j.appender.T=org.apache.log4j.FileAppender 
log4j.appender.T.File=debug.log 
log4j.appender.T.layout=org.apache.log4j.PatternLayout 
log4j.appender.T.layout.ConversionPattern=%p %t %c - %m%n 
log4j.appender.T.Threshold = DEBUG

您可以使用過濾器，org.apache.log4j.varia.LevelMatchFilter。例如：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE log4j:configuration PUBLIC "-//log4j/log4j Configuration//EN" 
            "log4j.dtd"> 
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> 

    <!-- INFO appender --> 
    <appender name="INFOFILE" class="org.apache.log4j.FileAppender"> 
     <param name="file" value="info.log" /> 
     <layout class="org.apache.log4j.PatternLayout"> 
      <param name="conversionPattern" 
       value="%d{yyyyMMdd-HHmmss.SSS} %-5p (%c.java:%L).%M - %m%n" /> 
     </layout> 
     <filter class="org.apache.log4j.varia.LevelMatchFilter"> 
      <param name="levelToMatch" value="INFO" /> 
     </filter> 
    </appender> 

    <!-- DEBUG appender --> 
    <appender name="DEBUGFILE" class="org.apache.log4j.FileAppender"> 
     <param name="file" value="debug.log" /> 
     <layout class="org.apache.log4j.PatternLayout"> 
      <param name="conversionPattern" 
       value="%d{yyyyMMdd-HHmmss.SSS} %-5p (%c.java:%L).%M - %m%n" /> 
     </layout> 
     <filter class="org.apache.log4j.varia.LevelMatchFilter"> 
      <param name="levelToMatch" value="DEBUG" /> 
     </filter> 
    </appender> 

    <!-- root --> 
    <root> 
     <priority value="ALL" /> 
     <appender-ref ref="INFOFILE" /> 
     <appender-ref ref="DEBUGFILE" /> 
    </root> 

</log4j:configuration>

將所有這些放在默認包中的一個文件中：log4j.xml。
