Registration and discovery of Eureka services

1. Create a new maven module subproject microservicecloud-eureka-server

2. pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>com.atguigu.springcloud</groupId>
        <artifactId>microservicecloud</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>

    <artifactId>microservicecloud-config-eureka-client-7001</artifactId>

    <dependencies>
        <!-- SpringCloudConfig配置 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
        <!-- 热部署插件 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>springloaded</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
    </dependencies>
</project>

三 、 application.yml

server:
  port: 7001
  
eureka:
  instance:
    hostname: localhost    #eureka server instance name 
  client:
    register-with-eureka: false    #false means not to register myself in the 
   registry fetch-registry: false    #false means that my end is the registry, my duty is to maintain the service instance, and I don't need to retrieve the service 
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/ #Setting    the address query service and registration service that interact with Eureka Server need to rely on this address (the address exposed by the service)

Fourth, the main program

package com.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaServer7001_application 
{
    public static void main(String[] args) {
        SpringApplication.run(EurekaServer7001_application.class, args);
    }
}
