IOUtils.getBufferedWriter介绍

[英]Tries to open the specified file for writing and returns a BufferedWriter for it. If the filename ends with ".gz", data will be automatically gzip-compressed. The data written will be encoded as UTF-8 (only relevant if you use Umlauts or other characters not used in plain English).
[中]尝试打开指定的文件进行写入，并为其返回BufferedWriter。如果文件名以“.gz”结尾，数据将自动进行gzip压缩。写入的数据将被编码为UTF-8（仅当您使用Umlauts或其他非纯英语字符时才相关）。
