```xml
<dependency>
    <groupId>org.noear</groupId>
    <artifactId>dubbo-solon-plugin</artifactId>
</dependency>
```


#### 1、描述

分布式扩展插件。基于 dubbo2 适配的 rpc 插件。此插件需要使用 duboo 配套的注册与发现插件。

#### 2、配置示例

* pom.xml 增加专属的注册与发现服务包：

```xml
<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-registry-nacos</artifactId>
    <version>${dubbo2.version}</version>
</dependency>

<!-- 或者 zk（nacos 与 zookeeper 二选一，或者别的注册服务包） -->

<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-registry-zookeeper</artifactId>
    <version>${dubbo2.version}</version>
</dependency>
```

* app.yml 增加 dubbo 配置：

```yml
server.port: 8011

dubbo:
  application:
    name: hello
    owner: noear
  registry:
    address: nacos://localhost:8848
#    port default = ${server.port + 20000}
```
    
#### 3、代码应用

* 声明接口

```java
public interface HelloService {
    String sayHello(String name);
}
```

* 提供者（实现接口服务）

```java
@Service(group = "hello")
@EnableDubbo
public class DubboProviderApp implements HelloService{
    public static void main(String[] args) {
        Solon.start(DubboProviderApp.class, args);
    }
    
    @Override
    public String sayHello(String name) {
        return "hello, " + name;
    }
}

```

* 消息者

```java
@EnableDubbo
@Controller
public class DubboConsumeApp {
    public static void main(String[] args) {
        Solon.start(DubboConsumeApp.class, args, app -> app.enableHttp(false));

        //通过手动模式直接拉取bean
        DubboConsumeApp tmp = Solon.context().getBean(DubboConsumeApp.class);
        System.out.println(tmp.home());
    }

    @Reference(group = "hello")
    HelloService helloService;

    @Mapping("/")
    public String home() {
        return helloService.sayHello("noear");
    }
}

```
