我已经完成了FileRollerAppender
的课程FileAppender
。在我的新课程中,我需要重命名当前文件并从开始启动新文件。重命名文件的过程。
public void rollOver()
{
...
closeFile();
...
File file = new File(fileName);
file.renameTo(target);
}
现在,当logger尝试登录“hello”时,我有异常:
log4j:ERROR Failed to write [2014-02-18 09:21:42,941 26 [main] DEBUG sys.SuperBase - hello
].

如何告诉记录器重新创建文件?
答案 0 :(得分:0)
有理由自己创建吗? Log4j已经RollingFileAppender
有几个滚动策略 - 达到最大大小,数据/小时更改和启动时。查看更多here
如果你想实现自己的,你可以看看log4j的代码,看看它是如何实现的
