I have been trying to learn microservice development with spring boot and netflix oss.
I have been stuck with this eureka dashboard error for two days now and i can not seem to fix it. please help. I have a single discovery client instance and the server is in standalone mode This is how the dashboard looks like
Here is the server main class
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaApplication.class, args);
}
}
conf files application.yml
server:
port: 8761
eureka:
instance:
hostname: localhost
client:
registerWithEureka: false
fetchRegistry: false
serviceUrl:
defaultZone: ${eureka.instance.hostname}:${server.port}/eureka/
server:
waitTimeInMsWhenSyncEmpty: 0

The problem was with my application.yml file serviceUrl property value had a typo. I forgot to include http:// before the eureka.instance.hostname
Here is the fixed yaml
eureka:
instance:
hostname: localhost
client:
registerWithEureka: false
fetchRegistry: false
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
server:
waitTimeInMsWhenSyncEmpty: 0
It was never an issue with Brixton.RC1
No need to add spring-milestone as dependency as you are using release version.Its used only when you are using M version.See spring boot official doc for more details.Your code looks fine.It should work.Specify the error you are getting.Here is pom.xml and .yml file i am using which works.:
