Micro-services: Zuul & consul in Spring cloud application - spring-boot

Question

I'm trying to create a Spring cloud microservice application using Zuul and Consul.
I have 2 components in my project:
api-gateway microservice using Zuul
Hello world microservice (a simple hello world Rest Webservice)
Here is the code of The api-gateway:
#SpringBootApplication
#EnableZuulProxy
#EnableDiscoveryClient
public class ZuulApplication {
public static void main(String[] args) {
SpringApplication.run(ZuulApplication.class, args);
}
}
The pom.xml

application.yml
zuul:
routes:
hello1:
path: /hello1/**
serviceId: microservice-example
logging:
level:
org.springframework: INFO
com.netflix: DEBUG
bootstrap.yml
spring:
application:
name: edge-server
cloud:
consul:
config:
enabled: true
host: localhost
port: 8500
Here is the code of hello microservice:
#SpringBootApplication
#EnableConfigServer
#EnableDiscoveryClient
#RestController
public class Application {
#RequestMapping(value="/hello1",method = RequestMethod.GET)
public String hello() {
System.out.print("hello1");
return "Hello1";
}
public static void main(String[] args) {
new SpringApplicationBuilder(Application.class).web(true).run(args);
}
}
bootstrap.yml:
spring:
application:
name: microservice-example
profiles:
active: native
cloud:
consul:
config:
enabled: true
host: localhost
port: 8500
But, when I start the api-gateway I got the following exception:
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.netflix.zuul.filters.RouteLocator]: Factory method 'routeLocator' threw exception; nested exception is java.lang.IllegalStateException: Unable to locate service in consul agent: edge-server

Answer 1

This issue is fixed in Brixton.M3 (1.0.0.M5). As mentioned above this was an issue with spring-cloud-consul. The new version is working fine
