问题描述
我正在使用log4j2 ver 2.3
log4j2.xml看起来像:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<RollingFile name="RollingFile"
fileName="${sys:catalina.base}/logs/catalina.${date:yyyy-MM-dd}.log"
filePattern="${sys:catalina.base}/logs/catalina.%d{yyyy-MM-dd}.log">
<PatternLayout pattern="[TID=%X{TId}] %d{MMM dd, yyyy HH:mm:ss,SSS} %c %M:%L %p: %m%n"/>
<TimeBasedTriggeringPolicy modulate="true" />
</RollingFile>
</Appenders>
<Loggers>
<Root level="DEBUG" >
<AppenderRef ref="RollingFile" />
</Root>
</Loggers>
</Configuration>
一切正常，直到第二天的日志被当天的一些日志覆盖.
示例: CATALINA.2018-03-21.LOG昨天(3月21日)很好，但今天在Catalina.2018-03-22.log中被一些日志所覆盖，从今天(3月22日)
有什么想法吗?

log4j 2.3有些古老，于2015-05-09发行，近3岁.因此，尝试使用更新版本；版本2.11.0是目前发行的最新版本，该版本于2018-03-11发行.
更新:继续使用log4j 2.3，您可以妥协您的要求.选项之一可能是fileName属性使用静态值.例如. .../catalina.log，.../catalina.current.log，等等

尝试
BasicConfigurator.resetConfiguration()
在使用Logger之后使用 basic Configurator.configure()
的方法中其他推荐答案
尝试在文件模式(％i)中添加自动报重变量. 这对我来说很好.
filePattern="${sys:catalina.base}/logs/catalina.%d{yyyy-MM-dd}.%i.log"

All works fine until next day when log from a previous day is getting overwritten by some logs from current day.
Example: catalina.2018-03-21.log yesterday (March 21st) was fine but today got overwritten by some logs from 2018-03-22 when catalina.2018-03-22.log contains rest of logs from today (March 22nd)
Any thoughts?
推荐答案
Log4j 2.3 is somewhat old, being released on 2015-05-09, almost 3 years old. So try using a updated version; version 2.11.0 is the latest as of now which was released on 2018-03-11.
Update: To continue using Log4j 2.3, you can compromise your requirements. One of the options could be using static value for fileName attribute. E.g. .../catalina.log, .../catalina.current.log, etc.
其他推荐答案
try
BasicConfigurator.resetConfiguration()
in the method that uses logger after BasicConfigurator.configure()
其他推荐答案
Try adding an auto-increment variable to your file pattern (%i). This worked fine for me.
filePattern="${sys:catalina.base}/logs/catalina.%d{yyyy-MM-dd}.%i.log"
