I want to create an empty dummy resposne, I am going to use this to return when errors occur instead of passing back null.
我想创建一个空的虚拟 resposne，我将使用它在发生错误时返回而不是传回 null。

Just implement HttpResponsewith no-op methods.
只需HttpResponse使用无操作方法实现。

Indeed, implementing a HttpServletResponse seems quite a lot work, and you'll be dependent on the actual Servlet implementation.
实际上，实现 HttpServletResponse 似乎需要做很多工作，而且您将依赖于实际的 Servlet 实现。
I think I'd use request.getRequestDispatcher("/dummy.html").forward(request, response)
我想我会用 request.getRequestDispatcher("/dummy.html").forward(request, response)

Depending on what version of commons you're using, you might want to try DefaultHttpResponseFactory. This is the way that the library creates some of it's responses internally so it may or may not serve your purposes.
根据您使用的公共版本，您可能想尝试DefaultHttpResponseFactory。这是库在内部创建一些响应的方式，因此它可能会也可能不会满足您的目的。
import org.apache.http.HttpStatus;
import org.apache.http.HttpResponse;
import org.apache.http.HttpResponseFactory;
import org.apache.http.HttpVersion;
import org.apache.http.impl.DefaultHttpResponseFactory;
import org.apache.http.message.BasicStatusLine;
HttpResponseFactory factory = new DefaultHttpResponseFactory();
HttpResponse response = factory.newHttpResponse(new BasicStatusLine(HttpVersion.HTTP_1_1, HttpStatus.SC_OK, null), null);
