实例代码

引入dubbo 依赖

<!-- dubbo -->
<!-- zeekeeper注册中心 -->
<dependency>

服务

@Slf4j
public class DemoServiceImpl implements DemoService {
    @Override
    public String sayHello(String name) {
        log.info("[sayHello]start: {}", name);
        return "Hello " + name + " " + new Date();
    }
}

xml 配置

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://code.alibabatech.com/schema/dubbo
       http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    <!--定义了提供方应用信息，用于计算依赖关系；在 dubbo-admin 或 dubbo-monitor 会显示这个名字，方便辨识-->
    <dubbo:application name="demotest-provider" owner="programmer" organization="dubbox"/>
    <!--使用 zookeeper 注册中心暴露服务，注意要先开启 zookeeper-->
    <dubbo:registry address="zookeeper://59.110.240.159:2181"/>
    <!-- 用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" port="20880"/>
    <!--使用 dubbo 协议实现定义好的 api.PermissionService 接口-->
    <dubbo:service interface="DemoService" ref="demoService" protocol="dubbo"/>
    <!--具体实现该接口的 bean-->
    <bean id="demoService" class="DemoServiceImpl"/>
</beans>

启动类

@SpringBootApplication
@ImportResource(value = "classpath*:META-INF/provider.xml")
public class DubboProviderApplication {

    public static void main(String[] args) {
        SpringApplication.run(DubboProviderApplication.class, args);
    }

}
