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

dubbo-server.xml

<beans xmlns="http://www.springframework.org/schema/beans"

???<!--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jar
4:新建dubbo-client工程
5：bubbo-client-pom.xml

基于url发布无注册中心dubbo服务demo
