问题描述

如何让 log4j 删除旧的轮换日志文件?我知道我可以设置自动化作业(UNIX 的 cron 和 Windows 的计划任务)，但我希望它跨平台，并且我希望它作为我们应用程序的一部分在我们的应用程序的日志配置中，而不是在操作系统外部的单独代码中特定的脚本语言.我们的应用程序不是用操作系统脚本语言编写的，我不想在其中做这部分.

How can I get log4j to delete old rotating log files? I know I can set up automated jobs (cron for UNIX and scheduled task for Windows), but I want it cross platform, and I want it in our application's log configuration as a part of our application, rather than in separate code outside in OS specific scripting languages. Our application is not written in OS scripting languages, and I don't want to do this part of it in them.
