Log4j在webapp文件夹中找不到日志文件:在其配置文件下方:

Log4j can't find a log file in the webapp folder: Below its configuration file:

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

项目部署在 W:\ Media \ Projects \ Eclipse projects \ .metadata \ .plugins \ org.eclipse.wst.server.core \ tmp0 \ wtpwebapps \ my_project_name .也许我收不到东西，但似乎Log4j必须自动创建它.但它会显示错误日志:

Project is deployed at W:\Media\Projects\Eclipse projects\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\my_project_name. Maybe I can't get a something but seems Log4j must create it automatically. But it prints error log:

那我应该在哪里创建日志文件?

Where should I create my log file then?

推荐答案

好像您的日志文件路径未正确设置和/或您没有访问权限.我建议将其指向某个可写位置

Looks like your log file path is not setup properly and/or you don't have an acess to it. I suggest to point it to some writable location
