有没有内置的Go日志记录器可以在达到文件大小限制时滚动日志文件？
谢谢。

不，目前没有内置的记录器具有此功能。当搜索时，您会发现推荐使用_log4go_，但它目前存在一些问题，导致消息丢失（如果主程序退出并且某些消息仍在写入之前的通道缓冲区中）。大多数（如果不是全部）示例中都存在此问题。
另请参阅此问题。
英文:
No, there is no built-in in logger that currently has this feature.
log4go, which you will find recommended when searching, <del>is currently broken.</del> has some issues, that lead to messages getting lost (in case the main program exits and some messages are still in the channelbuffer before being written).
this is present in most if not all the examples.

从syslog包上面来看，这可能不是你真正想要的，标准库中没有这样的东西。
从第三方包中，例如log4go声称具有这个功能。
英文:
Above the syslog package, which probably is not what you really want, no such thing is in the standard library.
From the 3rd party packages, for example log4go claims to have this feature.
