项目DUBBO服务

DUBBO服务化开发手册:

一、导入JAR包

 

<!-- Dubbo -->
<dependency>
    <version>2.8.4</version>
    <artifactId>dubbo</artifactId>
    <groupId>com.alibaba</groupId>
</dependency>

二、配置spring-dubbo.xml文件

<?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">

	<!-- 具体的实现bean -->
	<bean id="demoService" class="com.alibaba.dubbo.demo.provider.DemoServiceImpl" />

	<!-- 提供方应用信息，用于计算依赖关系 -->
	<dubbo:application name="rule_engine" />

	<!-- 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 protocol="zookeeper" address="${zookeeper}" />
	<!-- 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.alibaba.dubbo.demo.DemoService"
		ref="demoService" timeout="1200000" />

</beans>

 

三、定义接口

package com.alibaba.dubbo.demo;
public interface DemoService {
	String sayHello(String name);
}

 

四、定义实现类

package com.alibaba.dubbo.demo.provider;
import com.alibaba.dubbo.demo.DemoService;
public class DemoServiceImpl implements DemoService {
	public String sayHello(String name) {
		return "Hello " + name;
	}
}
