1. 注册中心-eureka

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

server:
  port: 8761

spring:
  application:
    name: edu-eureka-boot
eureka:
  instance:
    hostname: localhost
  client:
    fetch-registry: false
    register-with-eureka: false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

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

@EnableEurekaServer
@SpringBootApplication
public class LagouEurekaApplication {

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

2. 配置中心

2.2 配置中心服务

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>

import org.springframework.cloud.config.server.EnableConfigServer;

@EnableConfigServer
@SpringBootApplication
public class LagouConfigApplication {

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