本文提供 java实现根据远程url下载文件到浏览器片段代码，仅供参考。

可以实现，根据远程url地址下载推送至浏览器下载，这个方法可以解决因前端直接调用远程url下载出现的跨域问题。

   /***  根据远程url下载文件* @param url 远程URL* @param response*/@RequestMapping("/url/download")public void douYinVideoDownload(String url, HttpServletResponse response) {BufferedInputStream inputStream = null;try {response.setContentType(MediaType.APPLICATION_OCTET_STREAM_VALUE);// 下载时候的文件名称和后缀FileUtils.setAttachmentResponseHeader(response, "test.zip");URL path = new URL(url);inputStream = new BufferedInputStream(path.openStream());byte[] bytes = new byte[1024];int len;while ((len = inputStream.read(bytes)) != -1) {response.getOutputStream().write(bytes, 0, len);}} catch (IOException e) {e.printStackTrace();} finally {if (inputStream != null) {try {inputStream.close();} catch (IOException e) {e.printStackTrace();}}}}
