如何使用一个log4j配置文件创建2个单独的日志文件？

Question

我不知道如何配置我的log4j，以使我的debugLog和reportLog彼此分开（不是附加的）。为什么在以下配置中，reportsLog始终为空？

log4j.rootLogger=TRACE, stdout, debugLog

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.debugLog=org.apache.log4j.FileAppender

log4j.appender.debugLog.File=logs/debug.log

log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout

log4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.reportsLog=DEBUG,reportsLog

log4j.appender.reportsLog=org.apache.log4j.FileAppender

log4j.appender.reportsLog.File=logs/reports.log

log4j.appender.reportsLog.layout=org.apache.log4j.PatternLayout

log4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

这是我的Java代码：

package test;

import org.apache.log4j.Logger;

import org.apache.log4j.PropertyConfigurator;

public class HelloLogger {

    static final Logger debugLog = Logger.getLogger("debugLog");

    static final Logger resultLog = Logger.getLogger("reportsLog");

    public static void main(String[] args) {

        PropertyConfigurator.configure("log4j.properties");

        debugLog.debug("Hello debugLog message");   

        resultLog.debug("Hello reportsLog message");

    }   

}

尝试以下配置：log4j.rootLogger=TRACE, stdoutlog4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%nlog4j.appender.debugLog=org.apache.log4j.FileAppenderlog4j.appender.debugLog.File=logs/debug.loglog4j.appender.debugLog.layout=org.apache.log4j.PatternLayoutlog4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%nlog4j.appender.reportsLog=org.apache.log4j.FileAppenderlog4j.appender.reportsLog.File=logs/reports.loglog4j.appender.reportsLog.layout=org.apache.log4j.PatternLayoutlog4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%nlog4j.category.debugLogger=TRACE, debugLoglog4j.additivity.debugLogger=falselog4j.category.reportsLogger=DEBUG, reportsLoglog4j.additivity.reportsLogger=false然后相应地用Java代码配置记录器：static final Logger debugLog = Logger.getLogger("debugLogger");static final Logger resultLog = Logger.getLogger("reportsLogger");您要输出到stdout吗？如果不是，请将第一行更改log4j.properties为：log4j.rootLogger=OFF并摆脱stdout界限。
