基于url发布无注册中心dubbo服务demo

1：创建dubbo-server maven工程

2：分别在dubbo-server下创建2个模块server-api（定义接口）和server-provider（实现接口）

server-api：

package com.cn.dubbo;

public interface IGpHello {

String sayHello(String msg);

}

server-provider：

package com.cn.dubbo;

public class GpHelloImpl implements IGpHello {    public String sayHello(String msg) {        return "hello yulong "+msg;    }}

package com.cn.dubbo;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

public class Bootstrap {    public static void main(String[] args) throws IOException {        ClassPathXmlApplicationContext context=                new ClassPathXmlApplicationContext("META-INF/spring/dubbo-server.xml");        context.start();        System.out.println("服务启动成功");        System.in.read();//阻塞进程    }}server-provider pom.xml 引入dubbo等jar包

</project>

dubbo-server.xml

<?xml version="1.0" encoding="UTF-8"?><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">

<!--提供方信息-->    <dubbo:application name="dubbo-server" owner="yulong" />    <!--注册中心-->    <dubbo:registry address="N/A"/>

<dubbo:service interface="com.cn.dubbo.IGpHello" ref="gpHelloService"/>

<bean id="gpHelloService" class="com.cn.dubbo.GpHelloImpl" />

</beans> 

3:idea工具mavenprojects 把dubbo-server打成jar包生成到本地，一会客户端引用jar4:新建dubbo-client工程5：bubbo-client-pom.xml
