搭建Eureka Client

1. pom.xml引入jar包

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

2. application.yml新增Eureka相關配置

   eureka:
     instance:
       instance-id: ${spring.application.name}  #註冊的這個服務的名字
     client:
       fetch-registry: true   # 從服務端獲取註冊的服務資訊
       register-with-eureka: true   #將自己註冊到註冊中心
       service-url:
         defaultZone: http://localhost:8300/eureka/ #Eureka地址
   

3. 主啟動類EurekaServer8300.java

   @SpringBootApplication
   @EnableEurekaClient
   //@EnableEurekaClient只適用於Eureka作為註冊中心，@EnableDiscoveryClient 可以是其他註冊中心。
   public class EurekaServer8300 {
   
       public static void main(String[] args){
           SpringApplication.run(EurekaServer8100.class, args);
       }
   }
