    <scope>import</scope>
</dependency>

</dependency>

這裏首先創建父項目，用來管理版本，這裏

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"?>

            </plugin>
        </plugins>
    </build>

</project>

再父項目創建一個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>

引入客戶端依賴

在屬性文件中 配置nacosserver地址

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

啓動nacos1項目，在控制檯查看是否注入成功

 

同樣的，孵化器版本依賴關係如下：

孵化器版本依賴關係(不推薦使用)

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	請注意， Spring Cloud Edgware 最低支持 Edgware.SR5 版本

依賴管理

Spring Cloud Alibaba BOM 包含了它所使用的所有依賴的版本。

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