JAVA之InputStream加载网络图片(填充到src)

@RequestMapping(value = "/queryCompanyImage", method = RequestMethod.GET)@ResponseBodypublic Result queryCompanyImage(HttpServletRequest request, HttpServletResponse response) throws IOException {    Result result = new Result();

try {        Long fileId = Long.valueOf(request.getParameter("fileOssId"));

InputStream fileOssRecordInputStream = null;

fileOssRecordInputStream = ossHelpService.downloadPriFile(fileId);//这是一个阿里云OSS下载图片得到InputStream的方法

BufferedInputStream reader = new BufferedInputStream(fileOssRecordInputStream);        BufferedOutputStream writer = new BufferedOutputStream(response.getOutputStream());

byte[] bytes = new byte[1024 * 1024];        int length = reader.read(bytes);        while ((length > 0)) {            writer.write(bytes, 0, length);            length = reader.read(bytes);        }        reader.close();        writer.close();

result.setSuccess(true);    } catch (Exception ex) {        log.error("获取产品图片异常", ex);        return new Result(false, "获取产品图片异常");    }    return result;

}
