Spring-cloud-netflix: Eureka Replicaiton problem.

[mekhaba]

Hi to all,
really I have an issue about Eureka Replicaton. In fact I follow the official doc in order to release it but I couldn't do it.
My config for Eureka Server is like

spring:
  application:
    name: eurekaserver
eureka:
  instance:
    metadata-map:
      instanceId: ${vcap.application.instance_id:${spring.application.name}:${spring.application.instance_id:${server.port}}}  
    leaseRenewalIntervalInSeconds: 3
    prefer-ip-address: true  
  client:
    serviceUrl:
      defaultZone: http://peer1:8761/eureka/, http://peer2:8761/eureka/    
    register-with-eureka: false
    fetch-registry: false
server:
  port: 8761

---
spring:
  profiles: peer1  
eureka:
  instance:
    hostname: peer1
---
spring:
  profiles: peer2  
eureka:
  instance:
    hostname: peer2

and my POM is :

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.4.RELEASE</version>
    </parent>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
        <!---->
        <dependency>
            <groupId>com.sun.jersey</groupId>

    </dependencies>

    <dependencyManagement>
        <dependencies>

                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Brixton.SR7</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

The log error that I had is :

 Cannot enhance @Configuration bean definition 'refreshScope' since its singleton instance has been created too early. The typical cause is a non-static @Bean method with a BeanDefinitionRegistryPostProcessor return type: Consider declaring such methods as 'static'.

Can you please give me some ways to do Eureka Replication (peer aware). Thanks in advance.

[spencergibb]

Brixton is no longer supported. Please try with Camden.SR7 or Dalston.SR4.

Also, these probably will work against replication since the server has to be a client of its peer.

    register-with-eureka: false
    fetch-registry: false

back,
I tried with Camden.SR7 but, still, the same error message :

[spencergibb]

It's not the same error.

[mekhaba]

Hi spencergibb,
Yes it is the new error, but when I used the : <version>Dalston.SR4</version> version the issue for replicaiton is FIXED.
So, for everyone who wants to use Eureka Replication, is recomended to use Dalston.SR4 version.
Another once, many thanks spencergibb for your help.
