所有已实现的接口：
HttpServletResponse, ServletResponse
直接已知子类：
CompressedResponseWrapper, FormAuthenticator.FormResponse, ServletResponseWrapperInclude
public class HttpServletResponseWrapper
extends ServletResponseWrapper
implements HttpServletResponse

Provides a convenient implementation of the HttpServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet. This class implements the Wrapper or Decorator pattern. Methods default to calling through to the wrapped response object.

从以下版本开始：
Servlet 2.3
