Delete zuul route dynamically without restarting the gateway

You can extend DiscoveryClientRouteLocator and add removeRoute() method: Here is my example of this

@SpringBootApplication
@EnableZuulProxy
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }


    public static class DeregistrableDiscoveryClientRouteLocator extends DiscoveryClientRouteLocator {
        private final ZuulProperties properties;
        public DeregistrableDiscoveryClientRouteLocator(String servletPath, DiscoveryClient discovery, ZuulProperties properties, ServiceInstance localServiceInstance) {
            super(servletPath, discovery, properties, localServiceInstance);
            this.properties = properties;
        }
        public DeregistrableDiscoveryClientRouteLocator(String servletPath, DiscoveryClient discovery, ZuulProperties properties, ServiceRouteMapper serviceRouteMapper, ServiceInstance localServiceInstance) {
            this(servletPath, discovery, properties, localServiceInstance);
        }
        //here is new method to remove route from .properties.getRoutes()
        public void removeRoute(String path) {
            this.properties.getRoutes().remove(path);
            refresh();
        }
    }

    @Bean
    DiscoveryClientRouteLocator discoveryClientRouteLocator(ServerProperties server, ZuulProperties zuulProperties, DiscoveryClient discovery, ServiceRouteMapper serviceRouteMapper, @Autowired(required = false) Registration registration) {
        return new DeregistrableDiscoveryClientRouteLocator(server.getServlet().getContextPath(),
                discovery, zuulProperties, serviceRouteMapper,
                registration);
    }

    @Component
    public static class AppRunner implements ApplicationRunner {
        @Autowired
        DeregistrableDiscoveryClientRouteLocator discoveryClientRouteLocator;

        @Override
        public void run(ApplicationArguments args) throws Exception {

            ZuulProperties.ZuulRoute zuulRoute = new ZuulProperties.ZuulRoute();
            zuulRoute.setId("google");
            zuulRoute.setServiceId("google");
            zuulRoute.setPath("/");
            zuulRoute.setUrl("http://google.com");
            zuulRoute.setRetryable(true);
            discoveryClientRouteLocator.addRoute(zuulRoute);

            //now remove the pre-added route.
            discoveryClientRouteLocator.removeRoute(zuulRoute.getPath());
        }
    }
}

So after that you can create a rest endpoint which will remove a route without restarting the server.
