java編寫簡單的dubbo及是提供者又是消費者

1.先啟動我上篇dubbo的提供者

pom.xml ，引入我啟動的提供者的包

 GuilfConsumerServiceImpl.java  這里有調用dubbo上面的提供者

package com.guilf1.service.impl;

import org.springframework.beans.factory.annotation.Autowired;

import com.alibaba.dubbo.config.annotation.Service;
import com.guilf1.service.api.GuilfConsumerServiceApi;
import com.guilf.service.api.GuilfDubboServiceApi;

public class GuilfConsumerServiceImpl implements GuilfConsumerServiceApi
{
　　　　// 調用dubbo上面的提供者
	@Autowired
	private GuilfDubboServiceApi guilfDubboServiceApi;

	public String findConsumerUser(String name, String password) {
		return "======nameConsumer:"+name+"=====password:"+password;
	}

	public String findProviderUser() {
		String str = guilfDubboServiceApi.findUser("guilf", "root");
		return "======nameConsumer:=====password:"+str;
	}
}

 GuilfConsumerServiceApi.java

package com.guilf1.service.api;

public interface GuilfConsumerServiceApi
{
	public String findConsumerUser(String name, String password);
	
	public String findProviderUser();
}

 TestMain.java

package com.guilf1.service.impl;
import java.io.IOException;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.guilf1.service.api.GuilfConsumerServiceApi;
import com.guilf.service.api.GuilfDubboServiceApi;

public class TestMain {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(    
                new String[]{"classpath:conf/spring.xml"});
		GuilfDubboServiceApi guilfDubboServiceApi =(GuilfDubboServiceApi)context.getBean("guilfDubboServiceApi");
		String str = guilfDubboServiceApi.findUser("wo", "ini");
		GuilfConsumerServiceApi guilfConsumerServiceApi = (GuilfConsumerServiceApi)context.getBean("guilfConsumerServiceApi");
		String str1 = guilfConsumerServiceApi.findProviderUser();
		System.out.println(str);
		System.out.println(str1);
        context.start();  
//        ClassPathXmlApplicationContext context1 = new ClassPathXmlApplicationContext(    
//                new String[]{"classpath:conf/dubbo-provider.xml"});
//        context1.start();  
        System.out.println("Press any key to exit111.");    
        try {
			System.in.read();
		} catch (IOException e) {
			e.printStackTrace();
		} 
	}
}

 啟動。里面及提供了自己的接口，也消費了上篇的提供者
