Windows Dubbo环境以及Dubbo实例搭建

1.安装dubbo依赖的常用的zookeeper注册中心

下载地址：http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz

解压 zookeeper-3.4.10.tar.gz，进入解压后conf目录下，复制zoo_sample.cfg文件，重命名为zoo.cfg即可

修改zoo.cfg文件

dataDir=D:\\software\\zookeeper
dataLogDir=D:\\software\\zookeeper

然后进入解压后bin目录，双击zkServer.cmd启动zookeeper

进入zookeeper-3.4.10\bin  Shift+右键调出cmd命令窗口：

D:\Program Files\zookeeper-3.3.6\bin>./zkCli.cmd -server 127.0.0.1:2181

如果出现如上图所示内容，表示zookeeper已经安装成功了

2.安装zkui(zookeeper的可视化操作工具)

下载https://github.com/DeemOpen/zkui  zkui安装包

下载之后进入zkui-master\ 目录下执行

mvn clean install

打包成功后在zkui-master\target目录下找到zkui-2.0-SNAPSHOT-jar-with-dependencies.jar包复制到zkui-master\ 目录下

然后在zkui-master\执行

java -jar .\zkui-2.0-SNAPSHOT-jar-with-dependencies.jar

执行结果如下：

然后打开网址：http://localhost:9090/

用户名：admin 密码：manager  用户名密码可以在zkui-master\config.cfg文件中配置，也可以在此文件中指定zookeeper的ip和端口

 

zkui感觉用处没多大，就是下面项目建立好之后启动项目进行消费 点击zkui菜单上Export会查看到zookeeper的活动

3.搭建Dubbo项目

创建maven工程

工程分为4个结构

• dubbo 工程，主工程，主要导入公共jar包等
• dubbo-api 工程，公共接口
• dubbo-provider 工程，服务提供者
• dubbo-consumer 工程，服务消费者 

先创建父dubbo工程

Eclipse>file>new>Maven Project 然后建立maven项目

Finish之后我们是无法add Maven Module子工程的

我们需要做一下操作

1.pom.xml替换成下面内容

<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.feeling.dubbo</groupId>
  <artifactId>dubbo</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>pom</packaging>
  
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
  </properties>
 
</project>

然后我们会发现项目会报错

鼠标放在dubbo工程上右键>maven>Update Project

然后删除上图红色方框圈住的文件，然后变成如下：

然后鼠标放在dubbo工程上右键 >Build  Path > Configure Build  Path......

将Source和Libraries 下的内容全部Remove

然后Apply and Close,结果如下：

然后我们就可以放心的建依赖于dubbo的子工程了。

dubbo > 右键 > New > Maven Module

然后依次将剩下的两个子工程建好

• dubbo 工程，主工程，主要导入公共jar包等
• dubbo-api 工程，公共接口
• dubbo-provider 工程，服务提供者
• dubbo-consumer 工程，服务消费者 

 

在dubbo-consumer和dubbo-provider的pom中添加依赖，其中dubbo-api是dubbo-api接口子项目引入

 <dependencies>
  	<dependency>
  		<groupId>com.feeling.api</groupId>
  		<artifactId>dubbo-api</artifactId>
  		<version>0.0.1-SNAPSHOT</version>
  	</dependency>
  	<dependency>
    		<groupId>com.alibaba</groupId>
    		<artifactId>dubbo</artifactId>
    		<version>2.6.0</version>
    	</dependency>
        <dependency>
            <groupId>com.101tec</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.9</version>
		</dependency>
  </dependencies>

1.dubbo-api接口子项目创建ProviderService.java类

package com.feeling.api.service;

public interface ProviderService {
	public void sayHello();
}

2.dubbo-provider子项目（提供方）

ProviderServiceImpl.java

package com.feeling.provider.service.impl;

import com.alibaba.dubbo.rpc.RpcContext;
import com.feeling.api.service.ProviderService;

public class ProviderServiceImpl  implements ProviderService{

	public void sayHello() {
		// TODO Auto-generated method stub
		System.out.println("Hello "  + ", response form provider: " + RpcContext.getContext().getLocalAddress());
	}
	
}

application.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
 
    <!-- provider's application name, used for tracing dependency relationship -->
    <dubbo:application name="provider"/>
 
    <!-- use multicast registry center to export service 
    <dubbo:registry address="multicast://224.5.6.7:1234"/>-->
    
    <dubbo:registry address="zookeeper://localhost:2181"/>
 
    <!-- use dubbo protocol to export service on port 20880 -->
    <dubbo:protocol name="dubbo" port="20880"/>
 
    <!-- service implementation, as same as regular local bean -->
    <bean id="providerService" class="com.feeling.provider.service.impl.ProviderServiceImpl"/>
 
    <!-- declare the service interface to be exported -->
    <dubbo:service interface="com.feeling.api.service.ProviderService" ref="providerService"/>
 
</beans>

Provider.java启动类

package com.feeling.provider;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Provider {
	 
    public static void main(String[] args) throws Exception {
    	ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"application.xml"});
        context.start();
        System.out.println("----------------Provider服务已启动，按任意键结束···········--------------------");
        System.in.read(); // press any key to exit
    }
 
}

3.dubbo-consumer子项目

application.xml

<?xml version="1.0" encoding="UTF-8"?>
 
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
 
    <!-- consumer's application name, used for tracing dependency relationship (not a matching criterion),
    don't set it same as provider -->
    <dubbo:application name="consumer"/>
 
    <dubbo:registry address="zookeeper://localhost:2181"/>
 
    <!-- generate proxy for the remote service, then demoService can be used in the same way as the
    local regular interface -->
    <dubbo:reference id="providerService" check="false" interface="com.feeling.api.service.ProviderService"/>
 
</beans>

Consumer.java消费者启动类：

package com.feeling.consumer;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.feeling.api.service.ProviderService;

public class Consumer {
	 
    public static void main(String[] args) {
        System.setProperty("java.net.preferIPv4Stack", "true");
    	ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"application.xml"});
        context.start();
        ProviderService demoService = (ProviderService) context.getBean("providerService"); // get remote service proxy
 
        while (true) {
            try {
                Thread.sleep(1000);
                demoService.sayHello(); // call remote method
                System.out.println("----------------Consumer服务已启动调用接口，1s调用一次");
            } catch (Throwable throwable) {
                throwable.printStackTrace();
            }
 
        }
 
    }
}

 

启动项目：先运行Provider.java

然后再启动：Consumer.java会发现dubbo-provider中的实现类方法已经被调用；

 

3.搭建dubbo-admin控制台

1、下载地址：https://github.com/apache/incubator-dubbo/tree/dubbo-2.5.8/

2、解压后，打开cmd进入dubbo-admin目录下，如我解压的目录为：D:\Test\dubbo-master\dubbo-admin，在cmd下输入命令：mvn clean install

3、在target目录下生成dubbo-admin-2.5.8.war，然后将该war包放入tomcat的webapps目录下，启动tomcat， 访问localhost:8080/dubbo-admin-2.5.8，输入默认的用户名和密码：root/root   如图所示：

在当前页输入刚才项目中application.xml配置的<dubbo:application name="provider"/>   

搜索provider显示如下
