註冊和發現服務(Eureka)

Eureka客戶端依賴項添加到服務應用程序的構建中：

   <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            <version>2.1.0.RELEASE</version>
        </dependency>

applicationl.yml

spring:
  application:
    name: myFirstservice2

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
server:
  port: 0

說明：

spring.application.name：在Eureka中註冊服務的名稱，設置此屬性後，可以通過服務名稱myFirstservice2查找服務。

因爲你只會通過Eureka查詢服務，所以他們正在監聽的端口並不重要 - 尤里卡知道他們在哪個端口。因此，爲了避免在本地運行時發生潛在的端口衝突，可以將端口設置爲0：

eureka.client.service-url屬性：需要指定Eureka服務器的位置。這與Eureka服務器配置文件中的地址一至

調用微服務

@RestController
@RequestMapping(path = "/client",produces = "application/json")
@CrossOrigin(origins = "*")
public class IngredientServiceClient {
    private RestTemplate rest;

    public IngredientServiceClient(@LoadBalanced RestTemplate rest){
        this.rest=rest;
    }

    @GetMapping("/taco")
    public Taco getTaco(){
        //調用微服務myFirstservice
        return rest.getForObject("http://myFirstservice/design/taco",Taco.class);
    }

    @GetMapping("/mytest")
    public String getString(){
        return "lsjdlfjlksdjlf";
    }

}

@RestController
@RequestMapping(path="design",produces = "application/json")
public class MyserviceController {

    @GetMapping(path = "/taco")
    public Taco mytest(){
        Taco taco=new Taco();
        taco.setId(99);
        taco.setName("雞腿漢堡");
        taco.setTitle("麥當勞");
        return  taco;
    }
}

@SpringBootApplication
public class MyeurekaClientApplication {

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

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
}
