java浏览器下载

JAVA读取指定路径下文件，实现模拟浏览器下载文件，核心代码如下：

/*** 浏览器下载** @param sourceFilePath 源文件路径："D:\\demo.txt"* @param fileName       下载生成的文件名* @param response       响应浏览器*/public void browserDownload(String sourceFilePath, String fileName, HttpServletResponse response) {try (InputStream is = new FileInputStream(sourceFilePath);OutputStream os = response.getOutputStream();BufferedInputStream bis = new BufferedInputStream(is);BufferedOutputStream bos = new BufferedOutputStream(os)) {response.setContentType("application/octet-stream");response.setHeader("content-Disposition", "attachment;filename=" + new String(fileName.getBytes("GBK"), StandardCharsets.ISO_8859_1));int length = 0;byte[] temp = new byte[1024 * 10];while ((length = bis.read(temp)) != -1) {bos.write(temp, 0, length);}} catch (IOException e) {e.printStackTrace();}}
