> # dubbo服务基本搭建部署操作 #

### 1. 启动zookeeper: ###

（1）**[zookeeper下载地址][zookeeper]**：[http://zookeeper.apache.org/][zookeeper]；

（2）**解压并修改配置**

进入到zookeeper的conf目录，找到zoo\_sample.cfg文件将其重命名为zoo.cfg，然后打开该文件，  
将其中的dataDir和dataLogDir修改如下：

dataDir=E:\\test-project\\dubbo-demo\\data
    dataLogDir=E:\\test-project\\dubbo-demo\\log

###  2.dubbo接口服务api项目（其实该步上传jar包到Nexus可以用provider的jar包）： ###

注意：将其pom.xml中的打包方式改为jar；

public interface DemoService {
    	String sayHello(String name);
    }

【pom.xml配置】：

<?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"

          <url>http://.../nexus/content/repositories/snapshots/</url>
        </snapshotRepository>
      </distributionManagement>
    </project>

### 3.dubbo服务提供者provider项目：  ###

【pom.xml】配置三个核心依赖：

<dependency>
          <groupId>com.dubbo.api</groupId>
          <artifactId>api</artifactId>
          <version>1.0-SNAPSHOT</version>
        </dependency>
        
    
        
        <dependency>
          <groupId>com.alibaba</groupId>
          <artifactId>dubbo</artifactId>
          <version>2.5.3</version>
        </dependency>
    
        
        <dependency>
          <groupId>com.101tec</groupId>
          <artifactId>zkclient</artifactId>
          <version>0.10</version>
        </dependency>
        <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-context</artifactId>
          <version>4.0.5.RELEASE</version>
        </dependency>

【接口实现类】：

public class DemoServiceImpl implements DemoService {
    	@Override
    	public String sayHello(String name) {
    		return "Hello " + name;
    	}
    }

【provider.xml】配置：

<?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">
        
        <dubbo:application name="demo-provider" owner="nz" organization="dubbox"/>
        
        <dubbo:registry address="zookeeper://localhost:2181"/>
        
        <dubbo:protocol name="dubbo" port="20880" />
        
        <dubbo:service interface="com.dubbo.api.service.DemoService" ref="demoService" protocol="dubbo" />
        
        <bean id="demoService" class="com.dubbo.provider.service.impl.DemoServiceImpl"/>
    </beans>

【Provider用于启动项目Java代码】：启动服务提供者

public static void main(String[] args) throws IOException {
    	ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("provider.xml");
    	context.start();
    	System.out.println("dubbo服务提供端已启动....");
    	// 按任意键退出
    	System.in.read();
    }

### 4.dubbo消费者consumer项目：   ###

【pom.xml】配置三个核心依赖等同于 服务提供者：

【Consumer用于启动项目Java代码】：启动消费者：

public static void main(String[] args) throws IOException {
    	ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( "consumer.xml" );
    	context.start();
    	System.out.println("dubbo服务消费端已启动...");
    	// 获取远程服务代理
    	DemoService demoService = (DemoService)context.getBean( "demoService" );
    	// 执行远程方法
    	String hello = demoService.sayHello( "world" );
    	// 显示调用结果
    	System.out.println(hello);
    	// 按任意键退出
    	System.in.read();
    }

【consumer.xml】消费者配置：

### 5.dubbo-admin管理控制台： ###

通过dubbo-admin可以更好的管理dubbo服务，将dubbo-admin-2.6.0.war复制到tomcat的webapps目录下。然后启动tomcat,访问
    http://localhost:8080/dubbo-admin-2.6.0/（用户名和密码默认root）

通过网页进行管理dubbo服务 ：
