1.什么是Dubbo

简单来说dubbo就是分布式服务架构，是高性能和透明化RPC远程服务调用方案。

2.dubbo分为服务生产者(producer)和消费者(customer)两个模式。

3.配置文件：

<dubbo:application name="dubbo\_cfg"  />  
   
      
     
   
       
    <dubbo:registry address="zookeeper://10.10.110.35:2181" />  
   
      
    <dubbo:protocol name="dubbo" port="20881" />  
   
       
    <dubbo:reference id="serviceStore" version="v-fg"  
        interface="com.golden.port.framework.stores.IServiceStore"  
        retries="0" timeout="30000" />  
</beans>

图1-1 客户端的配置

服务端配置：

<dubbo:application name="fg"  />  
   
      
     
       
    <dubbo:registry address="zookeeper://10.10.110.35:2181" />  
      
    <dubbo:protocol name="dubbo" port="10880" />  
   
       
    <bean id="serviceStore" class="com.wawj.master.service.dubbo.impl.ServiceStore" />  
       
    <dubbo:service interface="com.wawj.master.service.dubbo.IServiceStore" ref="serviceStore" version="$\{dubbo.version\}"/>![Center 1][]

4.公共服务接口：

public interface IServiceStore \{  
      
      public abstract ResultValue access(String paramString, Map<String, Object> paramMap);  
  
\}

import com.wawj.master.service.dubbo.IServiceStore;  
import com.wawj.master.service.dubbo.results.ResultValue;  
  
public class ServiceStore implements IServiceStore\{  
    //服务器正常  
    public static int SUCCESS = 1;  
    //服务未知错误  
    public static int ERROR = 0;  
      
    private static final Logger logger = LoggerFactory.getLogger(ServiceStore.class);  
    @Autowired  
    private ApplicationContext context;  
      
    @Override  
    public ResultValue access(String path,Map<String, Object> param) \{  
          
        ResultValue resultValue = new ResultValue();  
        try \{  
            String \[\] obj\_method = path.split("\\\\.");  
            Object handler = context.getBean(obj\_method\[0\]);  
            String methodName = obj\_method\[1\];  
            Object result = null;  
            Method method = null;  
  
            if(null != param )\{  
                method= handler.getClass().getDeclaredMethod(methodName,Map.class);  
                result = method.invoke(handler,param);  
            \}else\{  
                method= handler.getClass().getDeclaredMethod(methodName);  
                result = method.invoke(handler);  
            \}  
              
            if(result!=null)\{  
                resultValue.setData(JSON.toJSONString(result));  
                resultValue.setCode(SUCCESS);  
                resultValue.setMessageCode("200");  
                resultValue.setMessageContent("访问成功");  
            \}else\{  
                resultValue.setCode(ERROR);  
                resultValue.setMessageCode("300");  
                resultValue.setMessageContent("数据异常");  
            \}  
            return resultValue;  
        \} catch (Exception e) \{  
            resultValue.setCode(ERROR);  
            resultValue.setMessageCode("500");  
            resultValue.setMessageContent("服务异常");  
            return resultValue;  
  
        \}  
  
    \}  
      
\}
