I am using configuration mode. Where is multiple (20) routes. But my server is accessible behind the URL PATH prefix http://prefixHere/method:port?property=value due Firewall and this can not be changed.
So when I have 20 of different methods (each ends in other service) then I must define 20 times.
I want to define the StripPrefix only once. This was working in previous Zuul gateway. How to do in cloud gateway?
Here is my config:
spring:
cloud:
gateway:
discovery:
locator:
lower-case-service-id: true
enabled: true
routes:
- id: auth-service
uri: lb://server-auth
predicates:
- Path=/prefixHere/auth/**
filters:
**- StripPrefix=1**
- id: operation-service
uri: lb://operation-service
predicates:
- Path=/prefixHere/operation/**
filters:
**- StripPrefix=1**
Yes, use "default-filters:" and it will be applied to all routes at once.
spring:
application:
name: gateway
cloud:
gateway:
default-filters:
- StripPrefix=1
E.g:
spring:
application:
name: GATEWAY-SERVICE
cloud:
gateway:
default-filters:
- StripPrefix=1
discovery:
locator:
enabled: true
lowerCaseServiceId: true
routes:
- id: department-service
uri: lb://department-service
predicates:
- Path=/api/departments/**
- id: user-service
uri: lb://USER-SERVICE
predicates:
- Path=/api/users/**

Now I want to be able to manipulate the Dropdown of the Servers field. The remote OpenAPI is sending me this localhost:8080 back, but I want to change it to a completely different URL. Do you know of any possiblity?
Add List of ur Servers in spring openApi Configuration like bellow:
import io.swagger.v3.oas.models.*;
#Configuration
public class OpenApiConfig {
#Bean
public OpenAPI openAPiConfig() {
ArrayList<Server> servers = new ArrayList<>();
servers.add(new Server().url("http://localhost:8080").description("Local Server"));
servers.add(...);
return new OpenAPI()
.info(new Info().title("My Service").description("My Service Description")
.license(new License().url("http://MyDomainLicence.com").name("My info"))
.contact(new Contact().name("contactName")
.email("myemail#gmail.com")
.url("http://contactDomain.com"))
.version("1.0.0"))
.servers(servers);
}
}

Your yaml is not valid. Check this validator as example.
Note how on line 16 and next, uri, predicates and path are not on the same column as just before.
Valid yaml is:
server:
port: 9190
spring:
application:
name: API-Gateway
cloud:
gateway:
routes:
- id: user-service
uri: lb://DEPT-SERVICE
predicates:

I'm on spring-cloud-starter-gateway (Hoxton.SR5) trying to support multiple hosts but not having luck.
I would like http://en.portal.com/common route to port 80 and http://us.portal.com/common route to port 81.
- id: host_route_en
uri: lb://127.0.0.1:80
predicates:
- Host=en.portal.com
- Path=/common/**
- id: host_route_us
uri: lb://127.0.0.1:81
predicates:
- Host=us.portal.com
- Path=/common/**
Could you guide how to achieve that.
Change it to
spring:
cloud:
gateway:
routes:
- id: host_route_en
uri: http://127.0.0.1:80
predicates:
- Host=en.portal.com
- Path=/common/**
- id: host_route_us
uri: http://127.0.0.1:81
predicates:
- Host=us.portal.com
- Path=/common/**

I'm using spring cloud to manage my microservices.
For security reasons, for one specific microservice (name it ms_secure), I want to use custom route choose a specific microservice version depending on client IP.
My gateway config looks like this:
spring:
cloud:
gateway:
discovery:
locator:
enabled: true
routes:
- id: ms_secure_v1
uri: lb://ms_secure_v1
predicates:
- Path=/ms_secure/**
filters:
- RewritePath=/ms_secure/(?<segment>.*), /$\{segment}
- name: <my filter>
args:
xForwardedForHeaderName: X-Forwarded-For
hosts:
- <IP1>
- <IP2>
- id: ms_secure
uri: lb://ms_secure_v2
predicates:
- Path=/ms_secure/**
filters:
- RewritePath=/ms_secure/(?<segment>.*), /$\{segment}
- name: <my filter>
args:
xForwardedForHeaderName: X-Forwarded-For
hosts:
- <IP3>
- <IP4>
When when requesting /ms_secure:
IP1 and IP2 will be redirected to ms_secure_v1
IP3 and IP4 will be redirected to ms_secure_v2
My problem is that all my clients will also be able to access directly ms_secure_v1 or ms_secure_v2 by using the default routes:
http:///ms_secure_v1/...
http:///ms_secure_v2/...
I tried to disable these routes by using SetStatus GatewayFilter:
- id: setstatusstring_route
uri: lb://ms-gateway
predicates:
- Path=/ms_secure_v**
filters:
- SetStatus=403
But this route is not matched.
Is there a way to disable these default routes in spring gateway?
The following creates routes in gateway based on services registered:
spring:
cloud:
gateway:
discovery:
locator:
enabled: true
Set it to false (which is the default), if you don't want this.
