基於上一篇Microservices - Restful API HATEOAS介紹了支持 HATEOAS 特性的 Restful API,本篇介紹如何調用這樣的 Restful APIs,即 consumer client 端的代碼編寫。 Template method pattern

下載本文完整項目代碼 Github


我們使用 spring web 裡的 RestTemplate 去調用 Restful API,所以在 Spring Boot Maven 項目裡只需要添加這個依賴包


Create Client

創建一個新的類英雄管理者 HeroManager 來作為客戶端調用英雄的 Restful APIs

public class HeroManager implements CommandLineRunner {

	public static String BASE_URL = "http://localhost";

	public String serverPort;

	private final RestTemplate template = new RestTemplate();

	public void run(String... args) throws Exception {

		String heroUrl = BASE_URL + ":" + serverPort + "/hero";

		Hero batman = new Hero("Batman");

		BigInteger id = template.postForObject(heroUrl, batman, BigInteger.class);

		HeroResource hero = template.getForObject(heroUrl + "/{hero}", HeroResource.class, id);

		System.out.println("Got you " + hero.getName());



本地創建一個 MongoDB 服務

docker run --rm --name my-mongo -d -p 27017:27017 mongo


mvn spring-boot:run


2017-08-04 17:31:32.961  INFO 16292 --- [nio-8090-exec-1] org.mongodb.driver.connection            : Opened connection [connectionId{localValue:2, serverValue:7}] to localhost:27017
Got you Batman
2017-08-04 17:31:33.169  INFO 16292 --- [           main] wang.tiven.trycf.HeroApplication         : Started HeroApplication in 9.013 seconds (JVM running for 14.152)

  • Microservices - Architecture Microservice architecture (MSA) is an approach to building software systems that decomposes business domain models into smaller, consistent, bounded-contexts implemented by services. These services are isolated and autonomous yet communicate to provide some piece of business functionality. Microservices are typically implemented and operated by small teams with enough autonomy that each team and service can change its internal implementation details (including replacing it outright!) with minimal impact across the rest of the system.
  • Microservices - Load Balancing 在微服务架构中每个服务都可能有多个运行实例, 那么服务消费者在调用服务时怎么定位应该把请求发送给哪个实例呐? 这就是负载均衡 Load Balancing 要做的事情。Load Balancing 可以在服务端也可以是在消费端。
