dubbo spring 的使用

1：项目的架构，本项目使用的maven，分为三个模块。

api 为接口， server 为服务端 consumer 为调用端

2：api的模块结构

该模块主要是定义接口和实体。没什么具体介绍的。

3：server的模块结构

impl：api接口的实现类。DubboServer：服务启动。dubbo.xml配置详情。log 打印日志信息

pom文件代码

dubbo.xml代码

<?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:context="http://www.springframework.org/schema/context"

       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://www.springframework.org/schema/context

                        http://www.springframework.org/schema/context/spring-context-3.1.xsd

     http://code.alibabatech.com/schema/dubbo

     http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!-- 扫描包 -->

    <context:component-scan base-package="com.enjoy.service"/>

    <!-- 应用程序名称 -->

    <dubbo:application name="dubboServerApp" />

    <!-- 注册中心 -->

    <dubbo:registry address="zookeeper://192.168.30.128:2181" />

    <!-- 注册协议 -->

    <dubbo:protocol port="20881" name="rmi" />

    <dubbo:protocol port="20882" name="dubbo" />

    <!-- 暴露服务  interface 接口全路径  ref  实现类 -->

    <dubbo:service interface="com.enjoy.service.OrderService" ref="orderService" protocol="dubbo" />

</beans>

impl实现类代码

@Service("orderService")

public class OrderServiceImpl implements OrderService {

    public Integer bugShop(Integer money) {

        System.out.println("money的数值："+money);

        return money+1;

    }

}

启动类代码

public class DubboServer {

    public static void main(String[] args) {

        //启动dubbo

        ClassPathXmlApplicationContext context =

                new ClassPathXmlApplicationContext("classpath:dubbo.xml");

        context.start();

        System.out.println("-----dubbo开启-----");

        // 保证服务一直开着

        synchronized (DubboServer.class) {

            try {

                DubboServer.class.wait();

            } catch (Throwable e) {

            }

        }

    }

}

3：调用端的结构目录结构和服务端差不多一样，只不过少了实现类，调用者直接调用。pom文件都是一样的。

调用者主要是dubbo.xml不一样

<?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:context="http://www.springframework.org/schema/context"

       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://www.springframework.org/schema/context

                        http://www.springframework.org/schema/context/spring-context-3.1.xsd

     http://code.alibabatech.com/schema/dubbo

     http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!-- 应用程序名称 -->

    <dubbo:application name="dubboConsumerApp" />

    <!-- 注册中心 -->

    <dubbo:registry address="zookeeper://192.168.30.128:2181" />

    <!-- 注册协议 -->

    <dubbo:protocol port="20881" name="rmi" />

    <dubbo:protocol port="20882" name="dubbo" />

    <!-- 暴露服务  interface 接口全路径  id  spring的ID -->

    <dubbo:reference id="orderService" interface="com.enjoy.service.OrderService" protocol="dubbo" />

</beans>

测试类

public class DubboConsumer {

    public static void main(String[] args) {

        ClassPathXmlApplicationContext context =

                new ClassPathXmlApplicationContext("classpath:dubbo.xml");

        context.start();

        OrderService orderService = (OrderService)context.getBean("orderService");

        Integer order = orderService.bugShop(1);

        System.out.println(order);

    }

}

以上就是dubbo spring的使用。
