Question

我面临一个奇怪的问题。当我第一次关闭tomcat时，它会覆盖日志文件内容。但是，在第二次或任何后续重启时，我都不会面对这个问题。

我在登录tomcat shutdown时看到以下错误;

23:08:03,390 [] [] INFO XmlWebApplicationContext:873 - Closing Root WebApplicationContext: startup date [Wed Apr 29 23:47:05 BST 2015]; root of context hierarchy

日志配置

log4j.rootLogger=INFO, file

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=/logs/logfilename.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

可能的原因是什么？

我对其他应用程序有相同的log4j配置。但他们的工作非常好。看起来好像tomcat正在将日志写入应用程序日志而不是catalina。

仅在一天内首次重启且日志级别设置为INFO或DEBUG而非ERROR 时才会发生。

使用log4j Append变量。默认情况下它应该是真的......

log4j.appender.LOGFILE.Append=true

我也看到你正在使用Rolling Appender，但它不在你的根记录器中

log4j.rootLogger=INFO, file, RollingAppender

在tomcat关闭时正在覆盖日志文件
