</dependency>

这里首先创建父项目，用来管理版本，这里

springboot使用2.1.8

springcloud使用 Greenwich.SR3

springcloudalibaba使用2.1.2

POM如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>


        <!--lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>

            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>


    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

再父项目创建一个module nacos1

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>demo</artifactId>
        <groupId>com.spx</groupId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath>../demo1/pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>nacos1</artifactId>

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


</project>

引入客户端依赖

在属性文件中配置nacosserver地址

spring:
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
  application:
    name: nacos1
server:
  port: 8081

启动nacos1项目，在控制台查看是否注入成功

同样的，孵化器版本依赖关系如下：

孵化器版本依赖关系(不推荐使用)

Spring Cloud Version	Spring Cloud Alibaba Version	Spring Boot Version
Spring Cloud Greenwich	0.9.0.RELEASE	2.1.X.RELEASE
Spring Cloud Finchley	0.2.X.RELEASE	2.0.X.RELEASE
Spring Cloud Edgware	0.1.X.RELEASE	1.5.X.RELEASE

Note	请注意， Spring Cloud Edgware 最低支持 Edgware.SR5 版本

依赖管理

    <version>0.9.0.RELEASE</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

Spring Cloud Finchley
