nacos + dubbo + springboot 3.x搭建微服务调用环境

1. 环境准备

JDK17+
Maven 或 Gradle（用于构建项目）
nacos server （安装步骤 windows， docker desktop ）

2. 创建 Spring Boot 项目

2.1. 创建空的父类项目，更改项目打包方式为pom，引入相关依赖

......
<packaging>pom</packaging>

 <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.apache.dubbo</groupId>
                <artifactId>dubbo-spring-boot-starter</artifactId>
                <version>3.2.10</version>
            </dependency>

            <dependency>
                <groupId>org.apache.dubbo</groupId>
                <artifactId>dubbo-registry-nacos</artifactId>
                <version>3.2.10</version>
            </dependency>
        </dependencies>
    </dependencyManagement>       

2.2. 创建一个服务提供方和消费方都依赖的api模块。新建一个空的子项目，增加service

public interface DubboExampleService{

    String sayHello(String name);
}

2.3. 创建服务提供方项目

更新配置文件， 引入相关依赖

server:
  port: 8080

spring:
  application:
    name: dubbo-example-provider

dubbo:
  application:
    name: ${spring.application.name}
  protocol:
    name: dubbo # 通信协议
    port: -1 # dubbo协议端口
  registry:
    address: nacos://localhost:8848

        <dependency>
            <groupId>cn.myth</groupId>
            <artifactId>dubbo-example-api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>

        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <artifactId>dubbo-registry-nacos</artifactId>
        </dependency>

启动类增加EnableDubbo注解

实现api模块中的service

2.4. 创建消费者模块

更新配置文件，增加依赖

server:
  port: 8082

spring:
  application:
    name: dubbo-example-consumer

dubbo:
  application:
    name: ${spring.application.name}
  protocol:
    name: dubbo
    port: -1
  registry:
    address: nacos://localhost:8848

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
        </dependency>
         <dependency>
            <groupId>cn.myth</groupId>
            <artifactId>dubbo-example-api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <artifactId>dubbo-registry-nacos</artifactId>
        </dependency>

增加服务调用，服务注入使用dubbo相关注解 DubboReference，启动列增加注解EnableDubbo

3. 启动服务测试

  1. 启动nacos
  2. 启动dubbo-example-provider
  3. 启动dubbo-example-consumer

ok，测试完成
