Nacos入门

1.在父项目中引入SpringCloudalibaba依赖

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring.cloud-version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>2.2.5.RELEASE</version>
                <scope>import</scope>
                <type>pom</type>
            </dependency>
        </dependencies>
    </dependencyManagement>

2.在服务提供项目中新增Nacos服务发现依赖及配置

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

spring:
  application:
    name: consumer
  cloud:
    nacos:
      server-addr: localhost:8848

即可将服务注册到Nacos注册中心。

nacos服务的调用方式与Eureka的调用方式相同，都使用RestTemplate调用，同样需要在RestTemplate 注入方法上添加负载均衡注解

nacos服务分级存储模型：1.服务 2.集群 3.实例
