eureka server application.yml配置

server:
  port: 7001
eureka:
  instance:
    hostname: localhost#服务器ip
  client:
    register-with-eureka: false #server不需要注册为服务
    fetch-registry: false #表示自己就是注册中心，职责是维护服务实例，并不需要去检索服务
    service-url:
      defaultZone: http://eureka7002.com:7002/eureka/    #（eureka集群配置：互相注册）设置与eureka server交互的地址查询服务和注册服务都需要依赖这个地址

eureka server 主启动类

@SpringBootApplication
@EnableEurekaServer
public class CloudEurekaServer {

    public static void main(String[] args) {
        SpringApplication.run(CloudEurekaServer.class, args);
    }
}

eureka client yml配置

server:
  port: 80
spring:
  application:
    name: cloud-order-service
eureka:
  instance:
    instance-id: order${server.port} #服务名称
    prefer-ip-address: true #显示服务信息ip
  client:
    register-with-eureka: true 
    fetch-registry: true
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka #注册进eureka集群

eureka client config 配置(服务注册中心客户端通用设置)

@Configuration
public class ApplicationConfig {
    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

eureka client 消费者业务类Controller(服务注册中心均相同)

@RestController
public class OrderController {
    @Autowired
    private RestTemplate restTemplate;
    public static final String SERVICEURL = "http://cloud-provider-payment/"; #地址是 http + 服务spring.application.name名称
    @GetMapping("/consumer/payment/zk")
    public CommonResult paymentzk(){
        return restTemplate.getForObject(SERVICEURL + "payment/zk", CommonResult.class);
    }
}
