Idea环境下Dubbo+SpringMVC+ZooKeeper+Zkui实例程序

一、环境预备

由于要用到Dubbo和Zookeeper，所以需要提前将Dubbo+Zookeeper环境准备好。

1.Dubbo环境：Dubbo Admin管理平台配置方法。

启动服务后登录：（用户名/密码： root/root、guest/guest）

2.Zookeeper环境：ZooKeeper+Zkui安装配置

启动服务后登录：（用户名/密码： admin/manager）

二、用Idea工具搭建环境

具体步骤如下：

1.新建一个空的maven项目：

GroupId：com.dubbo，ArtifactId:Demo:

Project name:DubboDemo

点击完成。

2.在刚才的DubboDemo上创建一个Web项目（消费者）

右键-New-Module：

勾上Create from archetype，选择maven-archetype-webapp，下一步。

填写ArtifactId，如：comsumerdemo，下一步：

选择Maven信息，下一步：

完成！！！

3.在刚才的DubboDemo上创建一个项目（供应者）

下一步：

填写ArtifactId，如：providerdemo，下一步：

完成！

三、框架代码结构详情

1.DubboDemo空maven

除了pom.xml其他都可以删除（如：src等），DubboDemo的pom.xml内容：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.dubbo</groupId>
    <artifactId>Demo</artifactId>
    <packaging>pom</packaging>

    <modules>
        <module>consumerdemo</module>
        <module>providerdemo</module>
    </modules>
</project>

2.供应者providerdemo

2-1，代码结构：

2-2，pom.xml：

        </dependency>
    </dependencies>

</project>

2-3，IProviderService接口：

package com.dubbo.service;

/**
 * <p>Description:</p>
 * <p>com.dubbo.service</p>
 *
 * @author smartdt
 * @version 1.0
 * @date 2018/5/21
 */
public interface IProviderService {

    public String getString();
}

2-4，ProviderServiceImpl类：

package com.dubbo.service.impl;

import com.dubbo.service.IProviderService;

/**
 * <p>Description:</p>

 */
public class ProviderServiceImpl implements IProviderService {
    public String getString() {
        return "Hello Dubbo~";
    }
}

2-5，ProviderApplication类：

package com.dubbo;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

/**
 * <p>Description:</p>
 * <p>com.dubbo</p>

public class ProviderApplication {
    public static void main(String[] args) throws IOException {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("provider.xml");
        context.start();
        System.out.println("服务方开始提供服务~~~~~");
        System.in.read();
    }
}

2-6，provider.xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.消费者（consumerdemo）

配置：

3-1，代码结构：

3-2，pom.xml：

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

其中：

<dependency>
            <groupId>com.dubbo</groupId>
            <artifactId>providerdemo</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

是引用的providerdemo依赖关系。

3-3，ConsumerController类：

package com.dubbo.controller;

import com.dubbo.service.IProviderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * <p>Description:</p>
 * <p>com.dubbo.controller</p>
 *
 * @author smartdt
 * @version 1.0
 * @date 2018/5/21
 */

@Controller
@RequestMapping("/dubbo")
public class ConsumerController {

    @Autowired
    private IProviderService iProviderService;

    @RequestMapping("/hi.do")
    public String hi() {
        System.out.println("22222222222222222222222");
        String str = iProviderService.getString();
        System.out.println("服务方：" + str);
        return "dubbo";
    }
}

3-4，consumer.xml配置文件：

<?xml version='1.0' encoding='UTF-8'?>

</beans>

四、启动

1.先启动providerdemo的ProviderApplication:（供应者的方式还有其他方式）

服务方开始提供服务~~~~~

2.再通过tomcat配置consumerdemo后启动：

访问：http://localhost:8000/dubbo/hi.do

控制台：

22222222222222222222222
服务方：Hello Dubbo~

3.dubbo admin控制台

提供者：

消费者：

4.Zkui平台：
