How to use spring cloud gateway spring-boot?

Question

We were using netflix-zuul dependecy now the latest spring boot does support and we have to move to gateway.

ZuulRoute zuulRoute = new ZuulRoute();

zuulRoute.setPath("/newApi/**"); 
zuulRoute.setUrl("www.userinfo.com/user/er732/2/wecser");
zuulRoute.setSensitiveHeaders (new HashSet<String>());
final Map<String, ZuulRoute> routes = new HashMap<>();
routes.put("activity", zuulRoute); I
final ZuulProperties zuulProperties = new ZuulProperties(); z
uulProperties.setRoutes (routes);
final ZuulProperties. Host host = new ZuulProperties.Host(); host.setConnectTimeoutMillis(68000); host.setSocketTimeoutMillis(128088);
zuulProperties.setHost(host);
return zuulProperties;

How can we achieve the same with the Spring cloud gateway with the minimal changes so that my application can be running back
