Create Eureka Server

1. Add dependency

   <dependencies>
       <!--eureka服务端-->
       <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
       </dependency>
   </dependencies>
   

2. Add annotation

   @EnableEurekaServer
   @SpringBootApplication
   public class EurekaApplication {
       public static void main(String[] args) {
           SpringApplication.run(EurekaApplication.class,args);
       }
   }
   

3. Add config

   server:
     port:10086 # 服务端口
   spring:
     application:
       name:eurekaserver
   eureka:
     client:
       service-url: # eureka address
         defaultZone: http://127.0.0.1:10086/eureka
   

Registered list

Register user-service

1. Add dependency in user-service

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

2. Add config

   spring:
     application:
       name: eurekaserver
   eureka:
     client:
       service-url: # eureka address
         defaultZone: http://127.0.0.1:10086/eureka
   

Register another user-service
