Unable to forward Request to URI with context-path

I am unable to forward my request to a URI with contextpath.

For example I am requesting my Spring cloud gateway server with

And I expect it to forward to

But It gives me 404

@Bean public RouteLocator customRouteLocator(RouteLocatorBuilder builder) { return builder.routes() .route("api-server-date", r -> r.host("**") .and() .path("/mygateway/server/date") .filters(f -> f.stripPrefix(1)) .uri("")) .build(); } 

It works when I change my configuration to this

@Bean public RouteLocator customRouteLocator(RouteLocatorBuilder builder) { return builder.routes() .route("api-server-date", r -> r.host("**") .and() .path("/mygateway/xyzapi/v1/server/date") .filters(f -> f.stripPrefix(1)) .uri("")) .build(); } 

I don't know what configuration I am providing wrong. It should work.

All I want is to use

As my URI. Meaning all Incoming traffic to my spring cloud gateway server should forward to this URL after appending the incoming url

Kindly suggest what is wrong ? Or is it something not possible with Spring Cloud Gateway ?

I think what you want (looking at online samples) is:

@Bean public RouteLocator customRouteLocator(RouteLocatorBuilder builder) { String requestHandlerUrl = ""; return builder.routes() .route("api-server-date", r -> r.host("**") .and() .path("/mygateway/server/date") .filters(f -> f.stripPrefix(1)) .uri(requestHandlerUrl) .build(); } 

... so that requests made to whatever host your app is deployed on are forwarded/passed to requestHandlerUrl as the destination.

It looks as if /mygateway/server/date is the "shortcut" or alias for the URL you actually want to handle the request.
