Log4j無法寫入日志文件

Question

Log4j在webapp文件夾中找不到日志文件：
在其配置文件下面：

log4j.rootLogger=DEBUG, STDOUT, FILE

log4j.appender.FILE=org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File=adminservtool.log
log4j.appender.FILE.MaxFileSize=16MB
log4j.appender.FILE.MaxBackupIndex=256
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=[%d{dd.MM.YYYY HH:mm:ss.SSS}] %5p [%t] - %m%n

log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.conversionPattern=[%d{dd.MM.YYYY HH:mm:ss.SSS}] %5p [%t] - %m%n
log4j.appender.STDOUT.Encoding=UTF-8

項目部署在W:\\Media\\Projects\\Eclipse projects\\.metadata\\.plugins\\org.eclipse.wst.server.core\\tmp0\\wtpwebapps\\my_project_name 。 也許我收不到東西，但似乎Log4j必須自動創建它。 但它會顯示錯誤日志：

那我應該在哪里創建日志文件？

Answer 1

看來您的日志文件路徑未正確設置和/或您沒有訪問權限。 我建議將其指向某個可寫位置
