日誌log4j中沒有生成文件

我是log4j的新手。我已經創建了一個實現log4j的示例java程序。日誌log4j中沒有生成文件

下面是Java程序：

package logging; 
import org.apache.log4j.BasicConfigurator; 
import org.apache.log4j.Logger; 
public class Logging { 
    /** 
    * @param args the command line arguments 
    */ 
    private static Logger logger = Logger.getLogger(Logging.class); 
    public static void main(String[] args) { 
     BasicConfigurator.configure(); 

     logger.trace("This is a Trace"); 
     logger.debug("This is a Debug"); 
     logger.info("This is an Info"); 
     logger.warn("This is a Warn"); 
     logger.error("This is an Error"); 
     logger.fatal("This is a Fatal"); 

    } 

}

我收到的控制檯輸出screen.But的日誌文件不是如何產生。我也使用以下鏈接在Eclipse霓虹燈中配置了我的項目： Configuration

我已經做得很好。但日誌文件沒有generating.When我實現log4j的編程文件越來越以下generated.The是我屬性文件：

#root 

log4j.logger.com.apress.logging.log4j=debug,dest 

log4j.additivity.com.apress.logging.log4j=false 

#define the appender 
log4j.appender.dest = org.apache.log4j.DailyRollingFileAppender 

#set the name of the file 
log4j.appender.dest.File=${user.home}/log.out 

#setting the immediate flush to true (default) 
log4j.appender.dest.ImmediateFlush=true 

#setting the threshold 
log4j.appender.dest.Threshold=ERROR 

#setting the append to false, overwrite 
log4j.appender.dest.Append=true 

#set the DatePattern 
log4j.appender.dest.DatePattern='.' yyyy-MM-dd

什麼我需要做的有Log4J的寫日誌文件？

檢查該文件的appender配置：HTTPS：//www.tutorialspoint。 COM/log4j的/ log4j_logging_files.htm – Maddy

嘗試使用「-Dlog4j.configuration = your_configuration_file」 INS運行配置 –

的log4j：WARN沒有這樣的屬性[conversion'enter]在org.apache.log4j.PatternLayout ?? – lpgad

確保log4j.properties在默認包

# Root logger option 
    log4j.rootLogger=DEBUG, stdout, file 
    log4j.logger.infoLogger=DEBUG, infoLogger 

    log4j.additivity.infoLogger = false 
    # Redirect log messages to console 
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
    log4j.appender.stdout.Target=System.out 
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
    log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n 

    # Redirect log messages to a log file, support file rolling. 
    log4j.appender.file=org.apache.log4j.RollingFileAppender 
    log4j.appender.file.File=E:\\LOG\\ConvertorLogger.log 
    log4j.appender.file.MaxFileSize=5MB 
    log4j.appender.file.MaxBackupIndex=10 
    log4j.appender.file.layout=org.apache.log4j.PatternLayout 
    log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n 

    # Redirect log messages to a log file, support file rolling. 
    log4j.appender.infoLogger=org.apache.log4j.RollingFileAppender

的log4j：WARN沒有這樣的財產[conv ersion'enter]在org.apache.log4j.PatternLayout中。 – lpgad

這是一個錯字...答案編輯。 –

你可以參考這個文件：log4j.properties

log4j.rootLogger=WARN,stdout,R 
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
    log4j.appender.stdout.layout.ConversionPattern=%d [%t] %-5p %c -%m%n 
    log4j.appender.R=org.apache.log4j.RollingFileAppender 
    log4j.appender.R.File=${user.home}/log.out 
    log4j.appender.MaxFileSize=100KB 
    log4j.appender.R.MaxBackupIndex=1 
    log4j.appender.R.layout=org.apache.log4j.PatternLayout 
    log4j.appender.R.layout.ConversionPattern = %p %t %c -%m%n 
    log4j.logger.com.foo=WARN
