**一**.linux系统部署自己的zookeeper，部署过程参考：[点击打开链接][Link 1] 其下载zookeeper的压缩包几次都失败，最终自己在本地下载好，上传到腾讯云主机中。参考文章的部署过程一次就成功了。

二. ** **IDEA搭建Spring boot 项目来形成一个服务提供方。

导入依赖

<dependency>
    			<groupId>com.alibaba</groupId>
    			<artifactId>dubbo</artifactId>
    			<version>2.5.7</version>
    			<exclusions>
    				<exclusion>
    					<groupId>log4j</groupId>
    					<artifactId>log4j</artifactId>
    				</exclusion>
    				<exclusion>
    					<groupId>commons-logging</groupId>
    					<artifactId>commons-logging</artifactId>
    				</exclusion>
    				<exclusion>
    					<groupId>org.springframework</groupId>
    					<artifactId>spring</artifactId>
    				</exclusion>
    				<exclusion>
    					<groupId>com.alibaba</groupId>
    					<artifactId>fastjson</artifactId>
    				</exclusion>
    			</exclusions>
    		</dependency>
    		<dependency>
    			<groupId>com.github.sgroschupf</groupId>
    			<artifactId>zkclient</artifactId>
    			<version>0.1</version>
    		</dependency>

resources下面建立providers.xml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"
           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="provider"/>
        
        <dubbo:registry address="zookeeper://115.159.**.***:2181" protocol="zookeeper" check="false"/>
        <dubbo:consumer check="false"/>
        
        <dubbo:protocol id="dubbo" name="dubbo" port="-1" threads="200" />
        
        <dubbo:service interface="com.sumu.service.ServiceInterface" ref="dubboService"/>
        
        <bean id="dubboService" class="com.sumu.service.ServiceImp"/>
    </beans>

@Service("dubboService")
    public class ServiceImp implements ServiceInterface {
        @Override
        public String dubboDemo(String name) {
            return "hello" + name;
        }
    }

@SpringBootApplication
    @ImportResource(value = {"classpath:providers.xml"})
    public class DubboDemoApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(DubboDemoApplication.class, args);
    	}
    }

在入口启动即可，为了直观看到自己的服务，这里使用dubbo-admin 来查看

然后是消费者

pom文件同提供者一样。

xml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"
           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="consumer"/>
        
        <dubbo:registry address="zookeeper://115.159.**.***:2181" protocol="zookeeper" check="false"/>
        
        <dubbo:reference id="dubboService" interface="com.sumu.service.ServiceInterface"/>
    </beans>

启动

![20171229155117754][]

dubbo-admin 下载dubbo-master后将文件夹相爱的dubbo-admin打成war包，放入到tomcat webapp/Root下解压 修改配置文件中的

dubbo.registry.address=zookeeper://115.159.\*\*.\*\*\*:2181  
dubbo.admin.root.password=root  
dubbo.admin.guest.password=guest

然后启动进入，用户名和密码都是root。。（开始一直以为密码是guest，一直进不去，报401的错误）
