Using JSR356 with Spark and Tomcat

[andersou]

Hi! I'm trying to use Websockets in Spark by running Tomcat. But the Spark filter is blocking the route to the Websocket. One suggestion is to implement a parameter in the filter to add URL's that are excluded from the Spark filter.

My solution:

public class SparkWebSocketFilter extends SparkFilter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        if(((HttpServletRequest)request).getServletPath().equals("/websocket")){
            chain.doFilter(request,response);
        }else
        super.doFilter(request, response, chain);
    }
}
