Question

我需要设置系统，可以通过以下方式将选定包（MyPck和MyPck1）中的INFO和DEBUG日志级别信息记录到所选文件中：

MyPck DEBUG goes to logFile
MyPck1 INFO goes to logFile

MyPck   INFO goes to debugLogFile
MyPck1 DEBUG goes to debugLogFile

我尝试使用Log4j.properties中的行：

log4j.logger.MyPck=DEBUG,logFile
log4j.logger.MyPck1=INFO,logFile

log4j.logger.MyPck=INFO,debugLogFile
log4j.logger.MyPck1=DEBUG,debugLogFile

不幸的是，debugLogFile获取信息并且logFile保持为空。如果我按照顺序更改log4j.properties中的行 - 首先是debugLogFile然后是logFile，我将把debugLogFile变为空。如何解决这个问题？

整个Log4J.properties设置：

log4j.rootLogger=TRACE, defaultFile

log4j.appender.defaultFile=org.apache.log4j.RollingFileAppender
log4j.appender.defaultFile.File=defaultFile.log
log4j.appender.defaultFile.Threshold=ALL
log4j.appender.defaultFile.MaxFileSize=100MB
log4j.appender.defaultFile.MaxBackupIndex=4
log4j.appender.defaultFile.layout=org.apache.log4j.PatternLayout
log4j.appender.defaultFile.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
log4j.appender.defaultFile.Append=false

log4j.appender.logFile=org.apache.log4j.RollingFileAppender
log4j.appender.logFile.File=logFile.log
log4j.appender.logFile.Threshold=ALL
log4j.appender.logFile.MaxFileSize=100MB
log4j.appender.logFile.MaxBackupIndex=4
log4j.appender.logFile.layout=org.apache.log4j.PatternLayout
log4j.appender.logFile.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
log4j.appender.logFile.Append=false

log4j.appender.debugLogFile=org.apache.log4j.RollingFileAppender
log4j.appender.debugLogFile.File=debugLogFile.log
log4j.appender.debugLogFile.Threshold=ALL
log4j.appender.debugLogFile.MaxFileSize=100MB
log4j.appender.debugLogFile.MaxBackupIndex=4
log4j.appender.debugLogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLogFile.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
log4j.appender.debugLogFile.Append=false

log4j.logger.MyPck=DEBUG,logFile
log4j.logger.MyPck1=INFO,logFile

log4j.logger.MyPck=INFO,debugLogFile
log4j.logger.MyPck1=DEBUG,debugLogFile

log4j.additivity.MyPck=false
log4j.additivity.MyPck1=false

主要课程：

package tst_log4j;
import org.apache.log4j.Logger;
import MyPck.C;
import MyPck1.C1;

public class Tst_Log4J 
{
public final Logger log = Logger.getLogger(getClass());

    public static void main(String[] args) 
    {
        C c = new C();
        c.doLog();
        C1 c1 = new C1();
        c1.doLog();
    }
}

MyPck课程：

package MyPck;

import org.apache.log4j.Logger;

public class C {
public final Logger log = Logger.getLogger(getClass());

public void doLog()
    {
    log.info("aaa");
    log.debug("bbb");
    log.error("ccc");

    }


}

MyPck1课程：

package MyPck1;

import org.apache.log4j.Logger;

public class C1 {
public final Logger log = Logger.getLogger(getClass());

public void doLog()
    {
    log.info("aaa");
    log.debug("bbb");
    log.error("ccc");

    }

}

Answer 1

您无法为记录器分配两个日志阈值。

log4j.logger.MyPck=DEBUG,logFile
log4j.logger.MyPck=INFO,debugLogFile

与

完全相同

log4j.logger.MyPck=INFO,debugLogFile

即。第一个作业被覆盖。要在两个日志文件中获得输出，您需要：

log4j.logger.MyPck=DEBUG,logFile,debugLogFile

Answer 2

您可以为每个方案创建一个appender，并注销两个方案。

放手一搏：

log4j.rootLogger=TRACE, defaultFile

log4j.appender.defaultFile=org.apache.log4j.RollingFileAppender
log4j.appender.defaultFile.File=defaultFile.log
log4j.appender.defaultFile.Threshold=ALL
log4j.appender.defaultFile.MaxFileSize=100MB
log4j.appender.defaultFile.MaxBackupIndex=4
log4j.appender.defaultFile.layout=org.apache.log4j.PatternLayout
log4j.appender.defaultFile.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
log4j.appender.defaultFile.Append=false

log4j.appender.myPckDebugAppender=org.apache.log4j.RollingFileAppender
log4j.appender.myPckDebugAppender.File=logFile.log
log4j.appender.myPckDebugAppender.Threshold=DEBUG
log4j.appender.myPckDebugAppender.MaxFileSize=100MB
log4j.appender.myPckDebugAppender.MaxBackupIndex=4
log4j.appender.myPckDebugAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.myPckDebugAppender.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
log4j.appender.myPckDebugAppender.Append=false

log4j.appender.myPckInfoAppender=org.apache.log4j.RollingFileAppender
log4j.appender.myPckInfoAppender.File=debugLogFile.log
log4j.appender.myPckInfoAppender.Threshold=INFO
log4j.appender.myPckInfoAppender.MaxFileSize=100MB
log4j.appender.myPckInfoAppender.MaxBackupIndex=4
log4j.appender.myPckInfoAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.myPckInfoAppender.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
log4j.appender.myPckInfoAppender.Append=false

log4j.appender.myPck1DebugAppender=org.apache.log4j.RollingFileAppender
log4j.appender.myPck1DebugAppender.File=debugLogFile.log
log4j.appender.myPck1DebugAppender.Threshold=DEBUG
log4j.appender.myPck1DebugAppender.MaxFileSize=100MB

log4j.appender.myPck1InfoAppender=org.apache.log4j.RollingFileAppender
log4j.appender.myPck1InfoAppender.File=logFile.log
log4j.appender.myPck1InfoAppender.Threshold=INFO
log4j.appender.myPck1InfoAppender.MaxFileSize=100MB
log4j.appender.myPck1InfoAppender.MaxBackupIndex=4

log4j.appender.myPck1InfoAppender.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
log4j.appender.myPck1InfoAppender.Append=false

log4j.logger.MyPck=DEBUG,myPckInfoAppender,myPckDebugAppender
log4j.logger.MyPck1=DEBUG,myPck1InfoAppender,myPck1DebugAppender

log4j.additivity.MyPck=false
log4j.additivity.MyPck1=false
