如何将 log4j 日志文件更改为 utf8

java logging utf-8 log4j

2022-09-02 14:09:39

我得到了一个使用log4j作为记录器应用程序的代码。如何为它生成 UTF8 日志记录文件？log4j 创建的日志文件目前采用 ASCII 格式。

我试过以下方法

按照说明设置日志文件的文件编码

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

事实上，在完成上述操作后，日志文件本身停止工作，即由于某种奇怪的原因，没有进一步的日志被写入文件

我还尝试更改.属性文件

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

由于某种原因，日志文件在滚动更新后采用 ASCII 格式

我正在使用 log4j 1.2.8

当我启用log4j调试时，我得到了以下输出
