1.dubbo依赖包

>  
> 
>     <properties>
>         <dubbo.version>2.7.8</dubbo.version>
>     </properties>
> 
>     <dependency>
>         <groupId>org.apache.dubbo</groupId>
>         <artifactId>dubbo-spring-boot-starter</artifactId>
>         <version>${dubbo.version}</version>
>     </dependency>
>     <dependency>
>         <groupId>org.apache.dubbo</groupId>
>         <artifactId>dubbo</artifactId>
>         <version>${dubbo.version}</version>
>     </dependency>
>     <dependency>
>         <groupId>org.apache.dubbo</groupId>
>         <artifactId>dubbo-registry-nacos</artifactId>
>         <version>${dubbo.version}</version>
>     </dependency>

2.springboot nacos 相关依赖包

>     <dependency>
>         <groupId>org.springframework.boot</groupId>
>         <artifactId>spring-boot-starter-web</artifactId>
>     </dependency>
>     <dependency>
>         <groupId>com.alibaba.cloud</groupId>
>         <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
>     </dependency>
>     <dependency>
>         <groupId>com.alibaba.cloud</groupId>
>         <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
>     </dependency>

3.模块划分

api 对内dubbo接口，对外fegin调用

web 模块 引用 api 模块 ，service 服务继承api定义的接口

>     <dependency>
>         <groupId>sfc-user</groupId>
>         <artifactId>user-api</artifactId>
>         <version>${project.version}</version>
>     </dependency>

@DubboService 注解 注入service

4.配置文件

##dubbo config
    dubbo.registry.address=nacos://127.0.0.1:8848
    ##dubbo nacos 命名空间 默认public
    dubbo.registry.parameters[namespace]=03fd8776-adba-45cd-9e9e-8d5ed320d71b
    dubbo.protocol.port=-1
    dubbo.protocol.name=dubbo
    demo.service.version=1.0.0

5.启动类 ，添加包扫描，如果配置文件中配置了 这里无须设置

@EnableDubbo(scanBasePackages = "com.sfc.base.service.impl")

启动 注册nacos

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNDUwMzUyNg_size_16_color_FFFFFF_t_70 1][]

6.以上是服务提供者，消费者 则引入api 依赖包以及上面的依赖包，配置dubbo 配置 ，启动类加上

@EnableDubbo

调用方加入 @DubboReference 注解，即可。

@DubboReference(version = "1.0.0", check = false)
