springboot根据uRL下载文件到本地

可以使用SpringBoot来实现根据URL下载文件到本地的功能。以下是一个示例代码：

@GetMapping("/download")
public void download(@RequestParam("url") String urlStr, HttpServletResponse response) throws IOException {
    URL url = new URL(urlStr);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");

    try (InputStream inputStream = conn.getInputStream();
         OutputStream outputStream = new FileOutputStream("路径/文件名")) {
        byte[] buffer = new byte<span class="em">1</span><span class="em">2</span>
