这是我使用PCF开发人员的第一个微服务。我创建了以下Eureka Server应用程序。
@EnableEurekaServer
@SpringBootApplication
public class EurekaServiceApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServiceApplication.class, args);
}
}
下面是eureka服务器服务的属性
eureka-service.register-with-eureka=false
eureka-service.fetch-registry=false
eureka-service.defaultZone=http://eureka-service.local.pcfdev.io/
eureka-service.logging.level.com.netflix.eureka=OFF
eureka-service.logging.level.com.netflix.discovery=OFF
下面是eureka客户端服务
@EnableDiscoveryClient
@SpringBootApplication
public class EurekaClientApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaClientApplication.class, args);
}
}
@RestController
class ServiceInstanceRestController {
@Autowired
private DiscoveryClient discoveryClient;
@RequestMapping("/service-instances/{applicationName}")
public List<ServiceInstance> serviceInstancesByApplicationName(@PathVariable String applicationName) {
return this.discoveryClient.getInstances(applicationName);
}
}
下面是eureka-client服务的属性
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
eureka.client.defaultZone=http://eureka-client.local.pcfdev.io/
eureka.client.logging.level.com.netflix.eureka=ON
eureka.client.logging.level.com.netflix.discovery=ON
我已经在本地运行的PCF Dev实例上部署了微服务
当我在本地将服务器和客户端作为Java应用程序运行时,我看到的响应来自 service-instances / eureka-client 端点。但是当我尝试调用以下端点时会得到一个空数组
http://eureka-client.local.pcfdev.io/service-instances/eureka-client
当我尝试使用URL访问eureka服务时
http://eureka-service.local.pcfdev.io/
我收到以下答复:
This site can’t be reached eureka-service.local.pcfdev.io refused to connect.

谢谢。
编辑1:
根据@Barath的评论,我如下修改了客户端应用程序的application.properties文件,但问题仍然没有消除。之前,我在application.properties文件中错误地引用了客户端应用程序名称。
eureka-client.register-with-eureka=true
eureka-client.fetch-registry=true
eureka-client.serviceUrl.defaultZone=http://eureka-client.local.pcfdev.io/
eureka-client.logging.level.com.netflix.eureka=ON
eureka-client.logging.level.com.netflix.discovery=ON
客户端的bootstrap.properties文件具有以下条目:
spring.application.name=eureka-client
服务器的bootstrap.properties文件具有以下条目:
spring.application.name=eureka-service
Edit-2
服务器:https://github.com/abnig/eureka-service 客户:https://github.com/abnig/eureka-client
答案 0 :(得分:1)
在eureka服务器和客户端中定义的属性如下所述
eureka服务器
eureka:
instance:
hostname: eureka-service.local.pcfdev.io
client:
fetch-registry: false
register-with-eureka: false
eureka客户端
eureka:
client:
serviceUrl:
defaultZone: https://eureka-service.local.pcfdev.io/eureka
register-with-eureka: true
fetch-registry: true
请参考spring-cloud-native供参考
