Spring ResponseFntity <inputstreamresource>由Jackson on FireFox 47

最新版本的FireFox（47）更改了为img标签发送的ACCEPT标头，并且通过此更改，我在向旧版本中运行的客户端编写输入流时遇到问题。目前我正在做以下

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.valueOf(artifact.getMimeType()));
headers.setContentDispositionFormData("attachment", artifact.getFilename());

InputStreamResource inputStreamResource = new InputStreamResource(artifact.getContents());
ResponseEntity<InputStreamResource> ent = new ResponseEntity<InputStreamResource>(inputStreamResource,headers, HttpStatus.OK);
return ent;

以前，FireFox已发送＆＃34; image / png，image / *; q = 0.8，* / *; q = 0.5＆＃34;作为ACCEPT标题，但最新更新它现在发送＆＃34; * / *＆＃34;其中org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodProcessor最终解析为基于Jackson的MessageConverter。我想弄清楚的是如何使用这个解决方案，以便使用org.springframework.http.converter.ResourceHttpMessageConverter，并按预期将输入流正确写入输出流。我知道我可以在FireFox配置中更改image.http.accept来实现这一点，但这不是一个可行的解决方案，因为我无法改变我环境中的任何客户端配置。

我知道我可以放弃InputStreamSource并相当轻松地手动写入输出流，但我很好奇＆＃34;对＆＃34;处理这个问题的方法是。我目前获得的堆栈跟踪列在下面

在阅读了更改来自的错误之后，假设内容协商不用于这些类型的请求是有问题的。由于我将Spring消息转换器用于依赖内容协商来选择正确转换器的应用程序，因此我知道有两种解决方案可以解决这个问题。第一种是使用pathExtensions或url参数来手动设置预期的内容类型（下面的示例配置）或者修改此特定端点的内容协商并自己处理对输出流的写入。由于内容协商并未真正使用（我们不是即时转换文件），因此我们选择简单地处理自己编写的输出。也许有一种不同的Spring方式可以说特定的端点应该始终由特定的MessageConverter处理，但我不知道这样做的设施。

<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorParameter" value="true"/>
<property name="mediaTypes">
    <map>
        <entry key="image" value="application/octet-stream"/>
    </map>
</property>

然后将正确处理使用http://host/app/1?format=image发出的请求。
