步驟如下： **1. 架構設計**  **2. 構建兩個服務端模塊**（我這里就不構建3個模塊了，只構建2個模塊） 兩個服務端模塊我已經提前構建好了，并將它們都注冊到了Eureka集群中，模塊名如下： ``` cloud-provider-payment8001 cloud-provider-payment8002 ``` **3. 兩個模塊的`resources/application.yml`配置** （1）模塊 cloud-provider-payment8001 的配置。 ```yml server: port: 8001 spring: application: name: cloud-payment-service eureka: client: service-url: #將當前模塊注冊到eureka集群中 defaultZone: http://www.eureka7001.com:7001/eureka/,http://www.eureka7002.com:7002/eureka/,http://www.eureka7003.com:7003/eureka/ instance: instance-id: ${project.artifactId} prefer-ip-address: true lease-renewal-interval-in-seconds: 1 lease-expiration-duration-in-seconds: 2 ####actuator#### info: app.name: ${spring.application.name} company.name: www.atguigu.com build.artifactId: ${project.artifactId} build.version: ${project.version} ``` （2）模塊 cloud-provider-payment8002 的配置。 ```yml server: port: 8002 spring: application: name: cloud-payment-service eureka: client: service-url: #將當前模塊注冊到eureka集群中 defaultZone: http://www.eureka7001.com:7001/eureka/,http://www.eureka7002.com:7002/eureka/,http://www.eureka7003.com:7003/eureka/ instance: instance-id: ${project.artifactId} prefer-ip-address: true lease-renewal-interval-in-seconds: 1 lease-expiration-duration-in-seconds: 2 ####actuator#### info: app.name: ${spring.application.name} company.name: www.atguigu.com build.artifactId: ${project.artifactId} build.version: ${project.version} ``` **4. 兩個模塊的controller代碼一樣，如下** ```java @RestController @RequestMapping("/payment") public class PaymentController { @Value("${server.port}") private String serverPort; @Value("${info.build.artifactId}") private String instanceId; @GetMapping("/idport") public String idPort() { return "instanceId：" + instanceId + "，serverPort：" + serverPort; } } ``` **5. 驗證是否構建成功** 分別啟動這兩個服務端模塊，然后分別訪問得到如下信息說明構建成功了。 :-: http://localhost:8001/payment/idport ``` instanceId：cloud-provider-payment8001，serverPort：8001 ``` :-: http://localhost:8002/payment/idport ``` instanceId：cloud-provider-payment8002，serverPort：8002 ```
