解决 JAVA读取本地ANSI文件乱码问题

XML解析经常因为ANSI出错误，如果是UTF-8就没问题。

private static String forTest(String file) throws IOException {File f = new File(file);InputStreamReader read = new InputStreamReader(new FileInputStream(f),"GBK");BufferedReader reader = new BufferedReader(read);String line;String s = "";while ((line = reader.readLine()) != null) {s = s+line;}return s;}
