How do I wire up spring oauth using spring eureka? - spring-boot

Question

I have created a Single Page Application using the Spring Tutorial for making one with AngularJS and OAuth and such found here:
https://spring.io/guides/tutorials/spring-security-and-angular-js/#_multiple_ui_applications_and_a_gateway_single_page_application_with_spring_and_angular_js_part_vi
This is the application.yml files for the SPA application:
security:
user:
password: none
oauth2:
client:
accessTokenUri: localhost:7777/uaa/oauth/token
userAuthorizationUri: localhost:7777/uaa/oauth/authorize
clientId: acme
clientSecret: acmesecret
resource:
user-info-uri: localhost:7777/uaa/user
zuul:
routes:
resource:
path: /resource/**
url: localhost:9000/resource
user:
path: /user/**
url: localhost:7777/uaa/user
eureka:
client:
serviceUrl:
defaultZone: ${vcap.services.eureka-service.credentials.uri:127.0.0.1:8761}/eureka/
---
spring:
profiles: cloud
eureka:
instance:
hostname: ${APPLICATION_DOMAIN}
nonSecurePort: 80
I want to know how I would change the zuul routes and the user-info-uri so that I don't have to specify the urls and all this can be done by using the service-id. I looked at the tutorial for using eureka here:
https://spring.io/blog/2015/01/20/microservice-registration-and-discovery-with-spring-cloud-and-netflix-s-eureka
but I don't quite understand how I can achieve my goal without adding all the java to my code, because the basic eureka server already seems to register all my services.

Answer 1

Had issue with using eureka service id, userInfoUri used to throw UnknownHost Exception all the time, #LoadBallanced restTemplate did not solve my issue, solution was to set prefer-token-info to false ( if true - no load ballancing for oauth )
security.oauth2.resource.service-id={Service ID as at eureka server registered}
security.oauth2.resource.userInfoUri= http://${security.oauth2.resource.service-id}/user/me
security.oauth2.resource.loadBalanced=true
security.oauth2.resource.prefer-token-info=false
no port number needed if service ID used , but needed if ip or host used

Answer 2

If I do understand your question correct you can just use the config file in this pattern:
zuul:
routes:
<service_id>:
path: /path/**
For example (if your oauth-service is registered as auth):
zuul:
routes:
auth:
path: /user/**
Zuul will leverage Eureka and find the endpoints for the services. In addition to that it will provide client-side load-balancing.
