package com.znn.provider; public interface DemoService { String sayHello(String name); }
新建一个服务提供方实现接口，对服务消费方隐藏实现
DemoServiceImpl.java
package com.znn.provider; public class DemoServiceImpl implements DemoService{ @Override public String sayHello(String name) { return "Hello Dubbo,Hello " + name; } }
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <!-- 提供方应用信息，用于计算依赖关系 --> <dubbo:application name="hello-world-app" /> <!-- 使用multicast广播注册中心暴露服务地址 --> <!-- <dubbo:registry address="multicast://224.5.6.7:1234" /> --> <!-- 使用zookeeper注册中心暴露服务地址 --> <dubbo:registry address="zookeeper://115.28.189.59:2181" /> <!-- 用dubbo协议在20880端口暴露服务 --> <dubbo:protocol name="dubbo" port="20880" /> <!-- 声明需要暴露的服务接口 --> <dubbo:service interface="com.znn.provider.DemoService" ref="demoService" /> <!-- 和本地bean一样实现服务 --> <bean id="demoService" class="com.znn.provider.DemoServiceImpl" /> </beans>
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 --> <dubbo:application name="consumer-of-helloworld-app"/> <!-- 使用multicast广播注册中心暴露发现服务地址 --> <!-- <dubbo:registry address="multicast://224.5.6.7:1234" /> --> <dubbo:registry address="zookeeper://115.28.189.59:2181" /> <!-- 生成远程服务代理，可以和本地bean一样使用demoService --> <dubbo:reference id="demoService" interface="com.znn.provider.DemoService" /> </beans>
新建一个测试类，当然具体用的时候会写一个专门的类使用IOC注入：
package com.znn.consumer; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.znn.provider.DemoService; public class Consumer { public static void main(String[] args) { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("file:D:/develop/myeclipsework/znn-service-consumer/WebRoot/WEB-INF/dubbo-consumer.xml"); context.start(); DemoService demoService = (DemoService)context.getBean("demoService"); // 获取远程服务代理 String hello = demoService.sayHello("world"); // 执行远程方法 System.out.println(hello); } }
