dubbo服务--点对点直连通信

dubbo直连通信是无注册中心的情况下，两进程之间的通信

服务提供者：

此进程有两个模块，一个模块是实现向外暴露的接口，一个模块是实现此接口的实现类：

ideal中编制order-api模块，提供向外的接口

public interface IOrderServices {
    DoOrderResponse doOrder(DoOrderRequest request);
}

 服务提供者order-provider模块：向外接口的实现类，具体的业务实现

public class OrderServiceImpl implements IOrderServices{

    @Override
    public DoOrderResponse doOrder(DoOrderRequest request) {
        System.out.println("曾来过："+request);
        DoOrderResponse response = new DoOrderResponse();
        response.setCode("1000");
        response.setMemo("处理成功");
        return response;
    }
}

 服务提供者模块下配置文件：具体说明如下

服务提供者启动类：

import com.alibaba.dubbo.container.Main;

public class App 
{
    public static void main( String[] args )
    {
        Main.main(args);
    }
}

 

 启动dubbo服务

信息:  [DUBBO] Export dubbo service com.gupao.vip.mic.dubbo.order.IOrderServices to url dubbo://192.168.19.56:20880/com.gupao.vip.mic.dubbo.order.IOrderServices?anyhost=true&application=order-provider&bind.ip=192.168.19.56&bind.port=20880&dubbo=2.6.2&generic=false&interface=com.gupao.vip.mic.dubbo.order.IOrderServices&methods=doOrder&owner=mic&pid=3400&side=provider×tamp=1550021134459, dubbo version: 2.6.2, current host: 192.168.19.56

 运行结果中显示了向外暴露服务的地址

dubbo://192.168.19.56:20880/com.gupao.vip.mic.dubbo.order.IOrderServices

服务消费者：

dubbo配置文件：

 获取服务，打印结果：

public class App 
{
    public static void main( String[] args )
    {
        ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext("order-consumer.xml");
        //获取服务提供者提供的服务
        IOrderServices services=  (IOrderServices)context.getBean("orderService1");
        DoOrderRequest request = new DoOrderRequest();
        request.setName("mic");
        DoOrderResponse response = services.doOrder(request);
        System.out.println(response);
    }
}

结果为：

 DoOrderResponse{data=null, code='1000', memo='处理成功'}
