Hi,
you could extend HttpServletResponseWrapper. You overwrite all
methods which you are interested in, save the values and call
the super method, so the underlying HttpServletResponse knows
them. Additionally you write getter methods, which return the
set values.
Example:
public class LocalHttpServletResponseWrapper
extends HttpServletResponseWrapper
{
public LocalHttpServletResponseWrapper(HttpServletResponse
res)
{
super(res);
}//constructor
public void setStatus(int sc)
{
super.setStatus(sc);
this.status = sc;
}//setStatus
public int getStatus()
{
return status;
}//getStatus
}//class
In your filter you receive a ServletResponse. Cast it to
HttpServletResponse. Instantiate your
LocalHttpServletResponseWrapper. Pass this new object to the
doFilter.
Afterwards you can use your getter methods. The caller of your
filter will have a normal ServletResponse.
Example:
public void doFilter(
ServletRequest req,
ServletResponse res,
FilterChain chain)
throws IOException, ServletException
{
HttpServletResponse hres = (HttpServletResponse) res;
HttpServletRequest hreq = (HttpServletRequest) req;
LocalHttpServletResponseWrapper lres
= new LocalHttpServletResponseWrapper(hres);
chain.doFilter(req, lres);
...
int status = lres.getStatus();
...
}
Good luck.
