篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了基于url发布无注册中心dubbo服务demo相关的知识，希望对你有一定的参考价值。
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
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

}
