上传文件类型异常，通过异常动作链，返回失败请求：

public class FailProcessor extends ViewProcessor{

	private static final Log LOG = Logs.get();

	/*@Override
	public void init(NutConfig config, ActionInfo ai) throws Throwable{
		this.view = evalView(config, ai, ai.getFailView());
	}*/

	@Override
	public void process(ActionContext ac) throws Throwable{
		Throwable error = ac.getError();
		String uri = Mvcs.getRequestPath(ac.getRequest());
		LOG.error(String.format("Error@%s :", uri));
		error.printStackTrace();
		UTF8JsonView UTF8JsonView = new UTF8JsonView(MvcConstant.JSONFORMAT);
		ApiResult apiResult=ApiResult.error(error);		
		UTF8JsonView.render(ac.getRequest(), ac.getResponse(),apiResult);
	}

POST http://192.168.199.219:8084/api/doc/upload/4 net::ERR_CONNECTION_RESET

有一种可能性是request流没有读取完，可以req.getInputStream并读取完它，然后写响应

java.io.IOException: Stream closed流已关闭

FastUploading类中抛异常，还有哪里处理过？而且写入Response未抛异常

                 // 检查是否通过文件名过滤
                    if (!context.isNameAccepted(meta.getFileLocalName())) {
                        throw new UploadUnsupportedFileNameException(meta);
                    }
                    // 检查是否通过文件类型过滤
                    if (!context.isContentTypeAccepted(meta.getContentType())) {
                        throw new UploadUnsupportedFileTypeException(meta);
                    }

没有了，浏览器问题吧

Response未响应返回

是怎样把req.getInputStream消耗完的?

UploadUnsupportedFileNameException异常被动作链FailProcessor拦截后，在方法process(ActionContext ac)中req.getInputStream试着读流，但已关闭，在判断文件后缀时，是否已读取文件流？
