【项目实践】_注册中心的搭建

1.1 注册中心服务搭建

引入注册中心maven坐标后，编写application.yml文件

• eureka注册中心

server:
  port: 8761
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
     defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

• nacos注册中心

引入坐标

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    <version>2.2.5.RELEASE</version>
</dependency>

yml文件

spring:
  application:
    name: nacos-test
  cloud:
    nacos:
      discovery:
        username: nacos
        password: nacos
        server-addr: localhost:8848
        namespace: public

编写启动类（nacos的注解@EnableDiscoveryClient）

package com.truly.app;

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

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