一、Nacos

　　官网：https://nacos.io/zh-cn/

　　一个更易于构建原生应用的动态服务发现、配置管理和服务管理平台。Nacos=注册中心+配置中心=Eureka+Config+Bus

二、Nacos作为服务注册中心

　　启动Nacos：/bin/startup.cmd启动Nacos，http://localhost:8848/，默认用户名与密码为nacos

1、Provider注册至Nacos

1.1、pom

<dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

pom

1.2、application.yml

server:
  port: 9001

spring:
  application:
    name: nacos-payment-provider
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848

management:
  endpoints:
    web:
      exposure:
        include: "*"

View Code

1.3、启动类

@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain9001 {
    public static void main(String[] args) {
        SpringApplication.run(PaymentMain9001.class, args);
    }
}

启动类

1.4、测试

　　启动模块cloudalibaba-provider-payment9001，查看Nacos，服务已注册至Nacos

2、Consumer注册至Nacos

2.1、pom

 <dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>

            <artifactId>cloud-api-common</artifactId>
            <version>${project.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
