Question

I’m trying to make the following test setup: Spring cloud gateway to forward messages internally to internal microservice. I tried this gateway project:

https://github.com/rcbandit111/gateway

Internal microservice:

https://github.com/rcbandit111/mockup

Routes setup into gateway:

    server:
      port: 8888
      servlet:
        context-path: /api
    spring:
      application:
        name: gateway
      cloud:
        gateway:
          routes:
            - id: mockup
              uri: lb://mockup
              predicates:
                - Path=/api/mockup/admin/**
              filters:
                - RemoveRequestHeader=Cookie
                - name: CircuitBreaker
                  args:
                    name: mockup
                - RewritePath=/api/mockup/admin/(?<path>.*), /mockup/admin/${path}

          httpclient:
            wiretap: true
          httpserver:
            wiretap: true

    logging:
      level:
        reactor:
          netty: DEBUG
        org:
          springframework:
            cloud:
              gateway: TRACE

Postman configuration for the call:

`curl –location –request POST ‘localhost:8888/api/mockup/admin/greeting’

Log files from Gateway:
