//输入流,通过输入流读取文件内容
try (FileInputStream fileInputStream = new FileInputStream(uploadFile)) {
ServletOutputStream outputStream = response.getOutputStream();
int len;
byte[] bytes = new byte[1024];
while ((len = fileInputStream.read(bytes)) != -1) {
outputStream.write(bytes, 0, len);
//刷新一下
outputStream.flush();
}
//关闭资源
outputStream.close();
return R.ok();
} catch (Exception e) {
throw new RuntimeException(e.getMessage(), e);
}

当然也可以通过NIOjava中pki代码的方式实现代码java中pki代码，具体可参见HttpServletResponse 返回图片java中pki代码的几种方法对比java中pki代码，核心代码如下：
fis.getChannel().transferTo(0,fis.available(),Channels.newChannel(response.getOutputStream()));
