1. 创建项目

在idea的File–New–Project中新创建一个Spring boot模板项目

点击next

点击next,如下：

修改pom.xml如下

修改配置文件application.yml如下：

server:
  port: 8811
  servlet:
    context-path: /eurekaprovide
#设置服务的名称
spring:
  application:
    name: eurekaprovide
eureka:
  client:
    service-url:
#Eureka 注册中心的地址，多个地址有逗号隔开
defaultZone: http://cluster1:7071/eureka,http://cluster2:8081/eureka,http://cluster3:9091/eureka

注册中心生产者如图：

访问地址：http://localhost:8811/eurekaprovide/hi?name=1231

            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
   </build>
</project>

修改yml配置文件如下：

server:
  port: 8101
  servlet:
    context-path: /eurekaconsumer
#设置服务的名称
spring:
  application:
    name: eurekaconsumer
eureka:
  client:
    service-url:
#Eureka 注册中心的地址，多个地址有逗号隔开
defaultZone: http://cluster1:7071/eureka,http://cluster2:8081/eureka,http://cluster3:9091/eureka
  instance:
    instance-id: eurekaconsumer
    prefer-ip-address: true

封装客户端：

@Configuration
public class ConfigBean {
@Bean
    @LoadBalanced// Spring Cloud Ribbon 是基于 Netflix Ribbon 实现的一套客户端
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
}

消费者调用接口：

@RestController
public class ConsumerController {
@Autowired
private RestTemplate restTemplate;
    private static final String REST_URL_PREFIX = "http://eurekaprovide";
@GetMapping(value = "/test/{name}")
public String test(@PathVariable("name") String name){
return restTemplate.getForObject(REST_URL_PREFIX + "/eurekaprovide/hi?name=" + name, String.class);
}
}

启动类EurekaconsumerApplication

@SpringBootApplication
@EnableEurekaClient
public class EurekaconsumerApplication {
public static void main(String[] args) {
      SpringApplication.run(EurekaconsumerApplication.class, args);
}
}

消费者启动：

注册中心展示：

调用接口：http://localhost:8101/eurekaconsumer/test/465
