How to add a /api/v1/ prefix to uri in spring cloud gateway? - regex

Question

I have two services and a gateway working with eureka:
user-service running on 8081
health-service running on 8082
So far I tried this:
routes:
- id: user-service-route
uri: http://localhost:8081/user-service
predicates:
- Path=/user-service/**
filters:
- RewritePath=(?<serviceName>.*), /api/v1/{serviceName}
But it doesn't work.

Answer 1

try
filters:
- RewritePath=(?<serviceName>.*), /api/v1/$\{serviceName}

Answer 2

Prefix location for all microservices if you use load balancer:
server:
port: 8765
management:
endpoints:
web:
exposure:
include: gateway
eureka:
client:
service-url:
defaultZone: http://localhost:8761/eureka
spring:
application:
name: gateway
cloud:
gateway:
discovery:
locator:
enabled: true
lower-case-service-id: true
default-filters:
- RewritePath=/api/v1/.*?/(?<remaining>.*), /$\{remaining}
routes:
- predicates:
- Path=/api/v1/profile/**
uri: lb://profile
- predicates:
- Path=/api/v1/dictionary/**
uri: lb://dictionary
