abdelgadiri commented on CXF-5201:
----------------------------------
As an additional check, I created the following Servlet filter to introspect
the response headers which confirmed to me that the response header set from
the JAX-RS interceptor is not being returned to the client.
@WebFilter(filterName = "ResponseDebugFilter", urlPatterns = {"/*"})
public class ResponseDebugFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
//do nothing
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse, FilterChain filterChain)
throws IOException, ServletException {
//carry on as normal
filterChain.doFilter(servletRequest, servletResponse);
//print response headers on way out
if (servletResponse instanceof HttpServletResponse) {
Collection<String> headerNames = ((HttpServletResponse)
servletResponse).getHeaderNames();
for (String hn : headerNames) {
Collection<String> headers = ((HttpServletResponse)
servletResponse).getHeaders(hn);
System.out.println("^^^^^^^^^^^^^^^^^^^^^^^^^^^^ found response
header (" + hn + "): " + headers);
}
}
}
@Override
public void destroy() {
//do nothing
}
}
> jaxrs2: unable to intercept response to add new response headers
> ----------------------------------------------------------------
>
> Key: CXF-5201
> URL: https://issues.apache.org/jira/browse/CXF-5201
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.7.5, 2.7.6
> Environment: windows
> Reporter: abdelgadiri
>
> In a WriterInterceptor, one expects to be able to modify response headers via:
> //here using putSingle() but could also use on of the addXXX variants
> context.getHeaders().putSingle("headerName", headerValue);
> However, above is not working in 2.7.5/2.7.6 (@see JIRA-4986)
> As a workaround, one should be able to inject the HttpServletResponse object
> via: @Context HttpServletResponse response;
> then be able to add headers directly to the response object e.g.,
> response.setHeader("headerName", headerValue);
> however, above is also not working in (2.7.5/2.7.6). This is not always
> reproducable as sometimes my client does see the new headers in the received
> response. On closer look it seems the added headers get lost when it is a
> @GET request as opposed to e.g., a @POST. Basically, my test case (a @GET)
> always fails with a missing header in the received response even though I am
> pretty sure the server had added the header.
