准备Dubbo的开发环境，包括Java，Maven，EclipseApache Maven 3.5.2 Maven home: E:\apache-maven-3.5.2\bin\..Java version: 1.8.0_151, vendor: Oracle CorporationJava home: C:\Program Files\Java\jdk1.8.0_151\jre
Dubbo入门实例规划1）使用Maven构建工程2）工程1：服务提供者，如test.love3）工程2：服务消费者，如 love.comsumer
构建工程1基本框架：服务提供者 ，需要在maven工程文件pom.xml中加入dubbo的依赖，dubbo版本号选2.5.8.Group ID: testartifact Id: lovepom.xml文件内容如下：
在工程1中，创建服务提供接口和实现类1）DemoService.java 文件package love;public interface DemoService { String sayHello(String name);}2)DemoServiceImpl.java文件package love;public class DemoServiceImpl implements DemoService { public String sayHello(String name) { return 'Hello ' + name; }}3) Lover.java文件package love;import java.io.IOException;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Lover { public static void main(String[] args) throws IOException { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( new String[] {'META/spring/dubbo-demo-provider.xml'}); context.start(); // press any key to exit System.in.read(); }}4）dubbo-spring服务配置文件META/spring/dubbo-demo-provider.xml
创建工程2基本结构，在maven的工程文件pom.xml文件中增加对dubbo和工程1的依赖
在工程2中实现服务消费的功能1）Consumer.java文件package consumer;import org.springframework.context.support.ClassPathXmlApplicationContext;import love.DemoService;public class Consumer { public static void main(String[] args) { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( new String[]{'META/spring/dubbo-demo-consumer.xml'}); context.start(); // obtain proxy object for remote invocation DemoService demoService = (DemoService) context.getBean('demoService'); // execute remote invocation String hello = demoService.sayHello('world'); // show the result System.out.println(hello); }}2）spring服务配置文件 META/spring/dubbo-demo-consumer.xml
启动工程1：服务提供者，开启服务运行工程1的lover类，看到如下日志信息表示启动成功十二月 29, 2017 11:06:18 上午 org.springframework.context.support.ClassPathXmlApplicationContext prepareRefresh信息: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@1099f62: startup date [Fri Dec 29 11:06:18 CST 2017]; root of context hierarchy十二月 29, 2017 11:06:18 上午 org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions信息: Loading XML bean definitions from class path resource [META/spring/dubbo-demo-provider.xml]十二月 29, 2017 11:06:18 上午 com.alibaba.dubbo.common.logger.LoggerFactory info信息: using logger: com.alibaba.dubbo.common.logger.jcl.JclLoggerAdapter十二月 29, 2017 11:06:18 上午 com.alibaba.dubbo.config.AbstractConfig info信息: [DUBBO] The service ready on spring started. service: love.DemoService, dubbo version: 2.5.8, current host: 127.0.0.1十二月 29, 2017 11:06:19 上午 com.alibaba.dubbo.config.AbstractConfig info信息: [DUBBO] Export dubbo service love.DemoService to local registry, dubbo version: 2.5.8, current host: 127.0.0.1
