[FIXED] Spring Cloud Gateway: why route uri property ignored?

Issue

I have only this route conf

spring.cloud.gateway.routes[0].id=x-service
spring.cloud.gateway.routes[0].uri=http://localhost:5555/x-service/v1/private/files
spring.cloud.gateway.routes[0].predicates[0]=Path=/v1/private/files

but app redirects to /v1/private/files.

How to fix this?

Solution

AFAIK spring-cloud-gateway Route builder takes into account only hostname and port passed to UriSpec.uri(String uri), so only http://localhost:5555 matters at this point.

So you need to rewrite your path, using RewritePath gateway filter, like this:

spring.cloud.gateway.routes[0].filters[0]=RewritePath=/v1/private/files, /x-service/v1/private/files

First argument is the original path, second - a replacer.
RegEx also can be used there.

Take a look at spring-cloud-gateway reference docs for details.
Also I suggest reading this article.
