IOUtils.getBufferedReader介绍

[英]Tries to open the specified file for reading and returns a BufferedReader for it. Supports gzip-compressed files, such files are automatically decompressed. If the file is not found, a gzip-compressed version of the file with the added ending ".gz" will be searched for and used if found. Assumes that the text in the file is stored in UTF-8 (without BOM).
[中]尝试打开指定的文件进行读取，并为其返回BufferedReader。支持gzip压缩文件，此类文件会自动解压缩。如果找不到该文件，将搜索并使用添加了结尾“.gz”的gzip压缩版本的文件。假定文件中的文本存储在UTF-8中（无BOM表）。
