   我理解应该是每次读一点（1M），然后就返回，所以第一个就读了1M就应该返回，那么就应该很快
   ================================
   demo如何准备那种带文件的? 其实我的代码就是这样
   
   Resource resource = new InputStreamResource(ret.getObjectContent()); // 这个就是一个比较大的文件流
   
    return ResponseEntity.ok()
                       .contentType(org.springframework.http.MediaType.parseMediaType(contentType))
                       .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + ret.getObjectKey() + "\"")
                       .body(resource);
   
   当调用这个的时候，我期待是立马返回，但是实际了隔了比较久的时间才返回。（用浏览器或者postman都有这种问题）
