java - 日志文件句柄如何设计比较好？

Question

写了一个异步服务器，用于处理网站的非实时性请求。目前每秒约写入10-100条日志，高峰时期可能写入约1000条日志。

我能想到的关于日志文件处理方法有下面几种，请问一般是如何实现的呢?

方法一：
每次写日志时获得文件句柄，写入后关闭。

方法二:
句柄作为单例，存在与整个程序生命周期，只有程序结束时才关闭。

方法三：
句柄作为单例，存在与整个程序生命周期，定期关闭重新打开。

Answer 1

Method 3 has been actually used in projects. Maybe my needs are slightly different from yours. The writing frequency of my logs generally does not exceed 10 entries/second, but the log files need to be saved on a daily basis and old files are deleted regularly (save logs of the past 7 days, etc.), so regular closing is a must~

Answer 2

Method 2, try opening the handle again when an error occurs

Answer 3

My question is, under Windows 2008, if the log handle is open, it cannot be copied and deleted.
This is very annoying. I hope I can view the log handle easily at any time. I don’t know how the first type of opening and closing frequency is very high, and how it affects the program and hard disk IO performance.

I haven’t used the log4cpp cplus log system yet, I don’t know what their design is!
