2、生产者

UserService 

public interface UserService {public String sayHello(String name);
}

UserServiceImpl

package com.example.dyc.mydubbo;public class UserServiceImpl implements UserService{@Overridepublic String sayHello(String name) {System.out.println("hello:"+name);return "hello:"+name;}}

provider.xml

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

启动类

package com.example.dyc.mydubbo;import org.springframework.context.support.ClassPathXmlApplicationContext;/*** Unit test for simple App.*/
public class ProviderTest {public static void main(String[] args) {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("provider.xml");context.start();System.out.println("dubbo服务提供端已启动....");try {System.in.read();} catch (Exception e) {e.printStackTrace();}}
}
