I have a spring boot app with simple GET method "sayHello" i have configured API gateway to route calls to my microservice module when uri pattern matches /ms1/**
Both gateway and microservice registered to the Registry service and dashboard displays both registered

return new ResponseEntity<String>(message, HttpStatus.OK);
}
}
I am getting following error when i access via gateway, however when i access my microservice directly it works any idea where i am wrong here?
http://localhost:8010/ms1/sayHello <- Not working via gateway
http://localhost:8030/ms1/sayHello <- Working direct access

I have faced the same issue today as well when running the micro services, the gateway and the Eureka discovery all on localhost.
I was able to solve it by adding eureka.instance.preferIpAddress=true to my application.properties of the micro services. That property causes that the services will advertise their IP addresses instead of the host names. More info here under point 2.6: https://cloud.spring.io/spring-cloud-netflix/multi/multi_spring-cloud-eureka-server.html. My guess is that there was an issue with forwarding the requests to the microservices due to using localhost.
Edit: Here are my settings
There is nothing special in my setup. These are the values I am using in my application.properties
The microservice is using:
spring.cloud.discovery.enabled=true
spring.application.name=[The name of my app]
eureka.client.register.with-eureka=true
eureka.client.service-url.defaultZone=http://localhost:8999/eureka
eureka.instance.prefer-ip-address=true
The properties for the gateway are similar to the service one.
The load balancing part looks like this:
spring.cloud.gateway.routes[0].id=[Same name as my app]
spring.cloud.gateway.routes[0].uri=lb://[name of my app]
spring.cloud.gateway.routes[0].predicates=Path=/test/**
Where test/** is the part of the Rest URL of my application
Adding DESKTOP-1.verizon.net to hosts file worked, following is entry I have added to C:\Windows\System32\drivers\etc\hosts file. Unfortunately eureka.instance.prefer-ip-address=true didn't work for me
127.0.0.1 DESKTOP-1.verizon.net
have added this settings in yml file in all services and its work for me.
eureka:
instance:
prefer-ip-address: true
I just faced the same issue, and in my case, I had a problem with port number. I was using the code below to set up the port for me:
server:
port: ${random.int(8010,8013)}
I noticed when the service starts, even though the log shows "Tomcat started on port(s): 8010", on Eureka's page shows "host.docker.internal:my-service:8011"
This error happens randomly, because sometimes when you re-start the microservice, it is able to register on Eureka correctly.
You can do a simple test using a non-random port number.
I haven't figured out how to solve it for random port number.
UPDATING:
I did this and worked fine for me:
server:
port: 0
spring:
application:
name: user-service
eureka:
instance:
hostname: localhost
prefer-ip-address: true
client:
serviceUrl:
defaultZone: http://localhost:9000/eureka/
We have developed Spring-boot microservices with NetFlix OSS/Spring-cloud. In the development environment, we are running with embedded tomcat, it works well.
Now I'm trying to deploy on Weblogic 12.1.2, I'm able to deploy service registry and API-Gateway inside two different managed servers. But When I open Eureka server page, API-Gateway is not registered with the Service Registry.

Could you please help me with following queries?
Is it possible to deploy Spring-Cloud on Weblogic 12.1.2?
Is it a correct way to deploy each microservice in a separate managed server?
If Yes, Am I missing any configuration so that api-gateway can register with service-registry?
I have a spring-boot application which I use to setup a spring cloud config server and a eureka server in development and testing environments.
Strangely the application always tries to connect to localhost:8761, even though I have eureka.client.registerWithEureka set to false.
How can I deactivate this?

Could you try to change your configuration like below
eureka:
client:
registerWithEureka: false
fetchRegistry: false
service-url:
defaultZone: http://localhost:8888/eureka
You specify server.port: 8888. So your eureka is running on 8888 port. But you didn't specify any service-url for eureka. So I think that your eureka server is trying to replicate to localhost:8761 because it's default and you didn't specify service-url for eureka.
For me, below properties that worked for me.
eureka.client.registerWithEureka= false
eureka.client.fetchRegistry= false
eureka.server.maxThreadsForPeerReplication=0
Please Use 8761 port for your Eureka server as below.
server:
port: 8761
eureka:
client:
registerWithEureka: false
fetchRegistry: false
Here we’re configuring an application port – 8761 is the default one for Eureka servers. We are telling the built-in Eureka Client not to register with ‘itself’, because our application should be acting as a server.
It seems that eureka tries to connect to itself despite the below settings:
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
you have two options to fix that 1-Keep the default port of eureka 2-Add below to your application.properties of your eureka server eureka.server.maxThreadsForPeerReplication=0
I am able to hit the service, if the flow doesn't contain Basic Authorization.
If i use Basic Authorization, it throws "message": "Full authentication is required to access this resource"
Below are my observations:
In ZuulFilter, run() method, i get value for
request.getHeader("Authorization") --> Basic c29tOnNvbzz==
but once it reaches the Micro Service, i am getting value as 'null',
request.getHeader("Authorization") --> null
Using Spring Boot version : 1.4.0.RELEASE
This is my flow:
------------------
Zuul -> Service Discovery (Eureka Server) -> Service
Kindly help, not sure where the Authorization header is vanishing.

Authorization is by default a sensitive header, this means Zuul will not forward them. If you leave it out of the sensitive headers, Zuul will forward the header.
zuul.sensitiveHeaders: Cookie,Set-Cookie
It should also be camelCase instead of hyphenated.
Extra info: https://github.com/spring-cloud/spring-cloud-netflix/blob/master/docs/src/main/asciidoc/spring-cloud-netflix.adoc#cookies-and-sensitive-headers
This solved my problem, but is this the only solution we have ?
ctx.addZuulRequestHeader("Authorization",request.getHeader("Authorization"))
Your property for zuul.sensitiveHeaders is wrong. It is camel case not hyphenated.
