1、NIO包中的操作

  String content = new String(Files.readAllBytes(Paths.get(ClassLoader.getSystemResource("static/xxxx.txt").toURI())), "utf-8");

2、ClassPathResource 读取 inputstream

        ClassPathResource classPathResource = new ClassPathResource("static/xxx.txt");
        InputStream inputStream = classPathResource.getStream();
        int fileLength = (int) classPathResource.getFile().length();
        byte b[] = new byte[fileLength];
        inputStream.read(b);
        inputStream.close();
        String str = new String(b, "utf-8");
