intercepting the page request in AEM-6.4
Hi Joerg,
Thanks a lot for your help and appreciated.
Currently the path is living in AEM and now I have written the below logic for my below requirement using sling filter.
Now my requirement is that when somebody will hit the PlanA (/content/trainingproject/Plan/PlanA) then it will redirect to SunitaFirst.html ( http://localhost:4502/content/trainingproject/Plan/PlanA/Location1/SunitaFirst.html ).
I have written the below code for this. But when I am trying to redirect then I am getting below error.
@SlingFilter(label = "Sample Filter", description = "Sample Description", metatype = true, generateComponent = true, // True if you want to leverage activate/deactivate
generateService = true, order = 0, // The smaller the number, the earlier in the Filter chain (can go negative);
scope = SlingFilterScope.REQUEST) // REQUEST, INCLUDE, FORWARD, ERROR, COMPONENT (REQUEST, INCLUDE, COMPONENT)
public class CustomRedirectFilter implements Filter {
Logger log = LoggerFactory.getLogger(this.getClass());
@Override
public void init(FilterConfig filterConfig) throws ServletException {
// Usually, do nothing
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
if (!(request instanceof SlingHttpServletRequest) || !(response instanceof SlingHttpServletResponse)) {
// Not a SlingHttpServletRequest/Response, so ignore.
chain.doFilter(request, response); // This line would let you proceed to the rest of the filters.
return;
}
final SlingHttpServletResponse slingResponse = (SlingHttpServletResponse) response;
final SlingHttpServletRequest slingRequest = (SlingHttpServletRequest) request;
final Resource resource = slingRequest.getResource();
log.info("resource is ----------- ====**** " + resource);
//String rootContentPath="/content/trainingproject/Plan/PlanA";
if (resource.getPath().startsWith("/content/trainingproject/Plan/PlanA")) {
// Is the SlingFilterScope is REQUEST, redirects can be issued.
// Write your custom code here.
slingResponse.sendRedirect("/Location1/SunitaFirst.html");
return;
}
// to proceed with the rest of the Filter chain
chain.doFilter(request, response);
}
@Override
public void destroy() {
// Usually, do Nothing
}
}
ERROR IS BELOW
Hi Joerg,
thanks for your help. Sorry for late reply. Now redirect is working fine.
But now , When I am running my page with the selectors , it is working fine , as shown below.
When I am not giving selectors then my page is not working fine , as shown below.
My code is below. Am I missing something "or" this is the expected behavior that in author it will not work and in publisher it will work.

Please suggest.
