开发配置

1、导包

//所有的SpringCloudAlibaba 应用都需要导入相关依赖包
 <properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <spring-boot.version>2.3.0.RELEASE</spring-boot.version>
        <spring-cloud-alibaba.version>2.2.1.RELEASE</spring-cloud-alibaba.version>
    </properties>
 <!--父依赖-->
    <dependencyManagement>
        <dependencies>
            <!--Alibaba dependency-->
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>${spring-cloud-alibaba.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!-- spring-cloud-dependencies -->
             <!--根据需求决定是否需要原生SpringCloud-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR3</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!--SpringBoot dependency-->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

项目开发之中至少要集成nacos的discovery包

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

需要配置服务的还需要额外集成config包

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

2、开发

1、在项目启动类上添加注解【@EnableDiscoveryClient】

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

2、编写配置文件

编写配置文件bootstrap.yml

server:
  port: 36001
spring:
  application:
    name: nacos-discovery-provider
  cloud:
    nacos:
      config:
        file-extension: yaml
        group: DEFAULT_GROUP
        refresh-enabled: true
        server-addr: 192.168.100.215:8848
      discovery:
        server-addr: 192.168.100.215:8848
        group: DEFAULT_GROUP
      password: nacos
      username: nacos
  profiles:
    active: dev
