开源分散式服务框架 Dubbo( 二 ) _生活百科

可视化的服务治理与运维提供丰富服务治理、运维工具：随时查询服务元数据、服务健康状态及调用统计，实时下发路由策略、调整配置参数。
例子服务端定义一个Service Interface：（HelloService.java）package com.alibaba.hello.api;public interface HelloService{ String sayHello(String name);}接口的实现类：（HelloServiceImpl.java）package com.alibaba.hello.impl;import com.alibaba.hello.api.HelloService;public class HelloServiceImpl implements HelloService{ public String sayHello(String name){ return "Hello" + name; }}Spring配置：（provider.xml）<?xmlversion="1.0"encoding="UTF-8"?><beans......>  <dubbo:applicationname="hello-world-app"/>  <dubbo:registryaddress="multicast://224.5.6.7:1234"/>  <dubbo:protocolname="dubbo"port="20880"/>  <dubbo:serviceinterface="com.alibaba.hello.api.HelloService"ref="helloService"/>  <beanid="helloService"class="com.alibaba.hello.impl.HelloServiceImpl"/></beans>测试代码：（Provider.java）importorg.springframework.context.support.ClassPathXmlApplicationContext;public class Provider{ public static void main(String[] args){ ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(newString[]{"provider.xml"}); //启动成功，监听连线埠为20880System.in.read();//按任意键退出 }}客户端Spring配置档案：(consumer.xml)<?xmlversion="1.0"encoding="UTF-8"?><beans xmlns=......>  <dubbo:applicationname="consumer-of-helloworld-app"/>  <dubbo:registryaddress="multicast://224.5.6.7:1234"/>  <dubbo:referenceid="helloService"interface="com.alibaba.hello.api.HelloService"/></beans>客户端测试代码：（Consumer.java）import org.springframework.context.support.ClassPathXmlApplicationContext;import com.alibaba.hello.api.HelloService;public class Consumer{ public static void main(String[] args){ ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(newString[]{"consumer.xml"}); HelloService helloService = (HelloService)context.getBean("helloService"); //getserviceinvocationproxyStringhello=helloService.sayHello("world"); //doinvoke!System.out.println(hello); //cool,howareyou~ }}
