dubbox生产者与消费者案例

一.首先要将dubbox添加到本地maven仓库

    参考:

https://blog.csdn.net/try_and_do/article/details/83383861

 

 

二.目录结构

 

三.生产者配置

applicationContext.xml

<?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="dubbox-provider" />

    <!-- 使用zookeeper注册中心暴露服务地址 -->

    <dubbo:registry address="zookeeper://192.168.42.88:2181" />

    <!-- 用rest协议在****端口暴露服务 -->

    <dubbo:protocol name="rest" port="8091" />

    <!-- 声明需要暴露的服务接口 -->

    <dubbo:service interface="com.chx.service.IDoSomeService" ref="iDoSomeService" />

    <!-- 和本地bean一样实现服务 -->

    <bean id="iDoSomeService" class="com.chx.service.impl.IDoSomeServiceImpl" />

</beans>

 

service接口

package com.chx.service;

 

 

import javax.ws.rs.Consumes;

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.PathParam;

import javax.ws.rs.core.MediaType;

 

 

@Path("/dosome")

public interface IDoSomeService {

    @GET

    @Path("/dosomeService/{id}")    //Rest风格

    @Consumes({ MediaType.APPLICATION_JSON })

    String dosomeService(@PathParam("id") Integer id);

 

 

}

实现类

package com.chx.service.impl;

 

 

import com.chx.service.IDoSomeService;

 

 

public class IDoSomeServiceImpl implements IDoSomeService {

    @Override

    public String dosomeService(Integer id) {

        System.out.println("执行业务!业务Id:"+id);

        return "doSome";

    }

}

main方法加载配置类

package com.chx.service;

 

 

import org.springframework.context.support.ClassPathXmlApplicationContext;

 

 

import java.io.IOException;

 

 

public class test {

    public static void main(String[] args) throws IOException {

        // 发布服务

        ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("applicationContext.xml");

        app.start();// 加载

        System.out.println("服务发布成功...");

        System.in.read(); // 让程序阻塞

    }

}

 

四.消费者配置

applicationContext.xml

<?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="dubbox-consumer" />

    <!-- 使用zookeeper注册中心暴露服务地址 -->

    <dubbo:registry address="zookeeper://192.168.42.88:2181" />

 

    <!-- 消费服务 -->

    <dubbo:reference interface="com.chx.service.IDoSomeService" id="iDoSomeService" />

 

</beans>

 

只保留接口不写实现,

main方法

package com.chx.service;

 

 

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

 

 

import java.io.IOException;

 

 

public class test {

    public static void main(String[] args) throws IOException {

        // 发布服务

        ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("applicationContext.xml");

        IDoSomeService iDoSomeService = (IDoSomeService)app.getBean("iDoSomeService");

        iDoSomeService.dosomeService(99);    //传递参数

    }

}

 

五.执行结果

 

浏览器rest风格调用返回结果
