dubbo+spring整合

---

api项目

• 声明接口

public interface service{}

---

provider项目

• pom文件

• applicationContext.xml
  文件需要放到META-INF/spring目录下（dubbo规范）

    <!-- 提供方应用信息，用于计算依赖关系 -->
    <dubbo:application name="dubbo_provider" logger="slf4j"/>

</beans>

• 接口实现

import com.alibaba.dubbo.config.annotation.Service;

@service
public class ServiceImpl implements Service{}

• 启动

public class Main {
    public static void main(String[] args) {
        com.alibaba.dubbo.container.Main.main(args);
    }
}

consumer项目

• applicationContext.xml

 <dubbo:application name="dubbo-consumer" logger="slf4j"/>
 <dubbo:registry address="zookeeper://47.105.47.171:2181"/>
 <dubbo:consumer check="false"/>

• 消费

import com.alibaba.dubbo.config.annotation.Reference;

@Reference
private Service service;
