2017年2月20日Dubbo远程调用服务框架部署

Registry可以用ZooKeeper实现

在Monitor里面安装Dubbo-monitor

在Provider端引入dubbo的依赖，使用spring配置注册中心和监控中心，并注册服务

<?xml version="1.0" encoding="UTF-8"?>
<beans ......>
　　<!-- Application name -->
　　<dubbo:application name="hello-world-app" />
　　<!-- registry address, used for service to register itself -->
　　<dubbo:registry address="multicast://224.5.6.7:1234" />
　　<!-- expose this service through dubbo protocol, through port 2 0 8 8 0 -->
　　<dubbo:protocol name="dubbo" port="2 0 8 8 0" />
　　<!-- which service interface do we expose? -->
　　<dubbo:service interface="com.alibaba.hello.api.HelloService" ref="helloService" />
　　<!-- designate implementation -->
　　<bean id="helloService" class="com.alibaba.hello.impl.HelloServiceImpl" />
</beans>

然后用一个包含main函数的类启动这个配置文件

import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Provider {
public static void main(String[] args) {
　　ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"provider.xml"}); //启动成功，监听端口为2 0 8 8 0
　　System.in.read(); // 按任意键退出
　　}
}

在Consumer端引入dubbo的依赖，使用spring配置注册中心和监控中心

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=......>
<!-- consumer application name -->
<dubbo:application name="consumer-of-helloworld-app" />
<!-- registry address, used for consumer to discover services -->
<dubbo:registry address="multicast://224.5.6.7:1234" />
<!-- which service to consume? -->
<dubbo:reference id="helloService" interface="com.alibaba.hello.api.HelloService" />
</beans>

最后在客户端消费服务

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(new String[] {"consumer.xml"});
　　　　HelloService helloService = (HelloService)context.getBean("helloService"); // get service invocation proxy
　　　　String hello = helloService.sayHello("world"); // do invoke!
　　　　System.out.println( hello ); // cool, how are you~
　　}
}
