如何在Spring Boot中如何返回InputStream时采用文件的模式呢？

下文笔者讲述SpringBoot返回InputStream时,采用文件模式返回的方法分享，如下所示

实现思路:返回时,加入参数HttpServletResponse即可注意事项:这种方式，就可以返回任意类型格式的数据至客户端pdf,excel,json,html等等

例:

 public static void sendFileInResponse (HttpServletResponse response, InputStream inputStream) throws IOException {response.setContentType("your_content_type");response.setHeader("Content-Disposition", "inline;filename=your_file_name");OutputStream outputStream = response.getOutputStream();byte[] buff = new byte[2048];int length = 0;while ((length = inputStream.read(buff)) > 0) {outputStream.write(buff, 0, length);outputStream.flush();}outputStream.close();inputStream.close();response.setHeader("Cache-Control", "private");response.setDateHeader("Expires", 0);
}
