我使用 apache common IO 将文本文件读入单个字符串

I use apache common IO to read a text file into a single string

String str = FileUtils.readFileToString(file);

简单和干净。你甚至可以毫无困难地设置文本文件的编码。

simple and "clean". you can even set encoding of the text file with no hassle.

String str = FileUtils.readFileToString(file, "UTF-8");
