public class TxtTest {    private static final Logger logger = LoggerFactory.getLogger(TxtTest.class);    public static String readTxt(File file) throws IOException {        String s = "";        InputStreamReader in = new InputStreamReader(new FileInputStream(file),"UTF-8");        BufferedReader br = new BufferedReader(in);        StringBuffer content = new StringBuffer();        while ((s=br.readLine())!=null){            content = content.append(s);        }        return content.toString();    }

public static void main(String[] args) {        try {　　　　　　　　//通过绝对路径获取文件            String s1  = TxtTest.readTxt(new File("C:\\Users\\....\\du.txt"));            logger.info(s1);

　　　　　　　　//spring boot中文件直接放在resources目录下            String s2 = TxtTest.readTxt(ResourceUtils.getFile("classpath:du.txt"));            logger.info(s2);        } catch (IOException e) {            e.printStackTrace();        }    }}
