For a quick solution, set the absolute path.
要快速解决，请设置绝对路径。

Above error giving you a hint that the appender file is not reachable/readable with current user access.
上述错误提示您当前用户访问权限无法访问/读取appender文件。
in brief we can say that- without administrative rights, no one cannot write a file at C: drive
简而言之，我们可以说-没有管理权限，没有人不能在 C: 驱动器上写入文件
As a quick remedy, change the log4j.appender.FILE.File setting to point to file by absolute path, for example /tmp/test.log. Now You should not get an exception.
作为快速补救措施，将 log4j.appender.FILE.File 设置更改为通过绝对路径指向文件，例如 /tmp/test.log。现在你不应该得到一个例外。
