  extended by javax.servlet.ServletResponseWrapper
      extended by javax.servlet.http.HttpServletResponseWrapper
所有已实现的接口:
HttpServletResponse, ServletResponse
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.
