搭建Eureka Client

pom.xml引入jar包

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

application.yml添加Eureka相关配置

eureka:
  instance:
    instance-id: ${spring.application.name}  #注册的这个服务的名字
  client:
    fetch-registry: true   # 从服务端获取注册的服务信息
    register-with-eureka: true   #将自己注册到注册中心
    service-url:
      defaultZone: http://localhost:8300/eureka/ #Eureka地址

主启动类EurekaServer8300.java

@SpringBootApplication
@EnableEurekaClient
//@EnableEurekaClient只适用于Eureka作为注册中心，@EnableDiscoveryClient 可以是其他注册中心。
public class EurekaServer8300 {

    public static void main(String[] args){
        SpringApplication.run(EurekaServer8100.class, args);
    }
}
