如何将log4j日志文件更改为utf8 [英] how to change log4j log file to utf8

问题描述

我已经交了一个使用log4j作为记录器应用程序的代码。如何为它生成UTF8日志文件？ log4j创建的日志文件目前是ASCII格式。

I have been handed a code which uses log4j as the logger application. How can I generate a UTF8 logging file for it?. The logfile being created by log4j is in ASCII format at the moment.

我试过以下

设置按照说明对日志文件进行文件编码

Setting the file encoding of the log file by following instructions

vi current
:set bomb
:set fileencoding=utf-8
:wq

在执行上述操作后，日志文件本身停止工作即由于某种奇怪的原因，没有其他日志被写入文件

Infact after doing the above the logfile itself stops working ie no further logs get written to the file for some strange reason

我也尝试更改.properties文件

I have also tried changing the .properties file

log4j.rootLogger=TRACE, logfile

log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.encoding=UTF-8
log4j.appender.logfile.File=/usr/vm/log/webconsole/current
log4j.appender.logfile.Append=true
log4j.appender.logfile.MaxFileSize=5MB
log4j.appender.logfile.MaxBackupIndex=1
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=[%5p] %d{ISO8601} (%F:%M:%L)%n%m%n%n

log4j.logger.com.company.npm=ALL
log4j.logger.org.apache.axis=OFF

翻转后的日志文件是由于某种原因的ASCII格式

The log file after it rolls over is in ASCII format for some reason

我正在使用log4j 1.2.8

I am using log4j 1.2.8

当我启用log4j调试时我得到了以下输出

When I enabled log4j debugging I got the following output
