Question

我正在尝试使用log4j在我的tomcat安装上的不同文件上记录某些消息，但是虽然它确实登录了我的rootLogger但它并没有在我正在创建的单独文件上执行此操作。

这是我的log4j.properies文件，我正在尝试使用的文件是dataflow_logging.log：

# Root logger option
log4j.rootLogger=INFO, stdout, mainlogger

# Direct dataflow specific messages to specific file.
log4j.logger.org.estat.nsiws.dataflows=INFO, dataflowlogger
log4j.appender.dataflowlogger=org.apache.log4j.RollingFileAppender
log4j.appender.dataflowlogger.File=${catalina.home}/logs/nsi/dataflow_logging.log
log4j.appender.dataflowlogger.MaxFileSize=10MB
log4j.appender.dataflowlogger.MaxBackupIndex=10
log4j.appender.dataflowlogger.layout=org.apache.log4j.PatternLayout
log4j.appender.dataflowlogger.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Disable dataflow log messages in root logger.
log4j.additivity.org.estat.nsiws.dataflows=false

# Direct main logging messages to standard output.
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{HH:mm:ss,SSS} [%p]: %m%n

# Also direct main logging messages to file.
log4j.appender.mainlogger=org.apache.log4j.RollingFileAppender
log4j.appender.mainlogger.File=${catalina.home}/logs/nsi/nsiws.log
log4j.appender.mainlogger.MaxFileSize=10MB
log4j.appender.mainlogger.MaxBackupIndex=10
log4j.appender.mainlogger.layout=org.apache.log4j.PatternLayout
log4j.appender.mainlogger.layout.ConversionPattern=%d{HH:mm:ss,SSS} [%p]: %m%n

我的WebService的属性文件：

## This file contains properties for the Web Service

# The absolute path to the logs directory
log.directory=logs/nsi

# The log file prefix
log.file.prefix=nsiws_

# The log file suffix
log.file.suffix=.log

# The prefix of the temporary files created for the buffering of responses.
tempfile.buffer.prefix=ws_resp

# Enable logging dataflow access
log.df.file.activation=true

# The absolute path to the dataflow logs directory
log.df.file.directory=logs/nsi

# The dataflow log file prefix
log.df.file.name=dataflow_logging

# The dataflow log file maximum size
log.df.file.max.size=100MB

# The dataflow max backup file
log.df.file.max.backup=10

# The dataflow log file separator
log.df.file.separator=;

# The dataflow log file date pattern
log.df.date.pattern=%d{yyyy-MM-dd HH:mm:ss,SSS};%m%n

初始化数据流记录器的方法：

private static Logger initDataflowLogger() {
        Logger dflogger = null;

        try {
            if (Boolean.parseBoolean(nsiProps.getProperty("log.df.file.activation"))) {
                dflogger = org.apache.log4j.Logger.getLogger("org.estat.nsiws.dataflows");
                dflogger.setLevel(Level.INFO);
                logger.debug("Initializing dataflow logging...");
            }
        } catch (Exception e) {
            logger.error(getInstance().getMessage("error.df.log.properties.not.set"));
        }

        return dflogger;
}

非常感谢你的帮助！

Answer 1

检查此表达式是否为true，以及是否正确设置了属性文件，以便项目可以从中读取。

Boolean.parseBoolean(nsiProps.getProperty("log.df.file.activation"))

Answer 2

您的根记录器处于INFO模式。
哪个不会记录调试级别语句。
你已经采用了org.estat.nsiws.dataflows（dataflowlogger Appender）的实例，这是＆＃34; dflogger＆＃34;但你实际上是在打电话给＃34; logger.debug＆＃34;

如何使用log4j配置tomcat登录其他文件？
