一、生产者简介：

（1） 服务提供方  
（2）伴随启动容器  
（3）服务注册

二、加载过程

三、应用类型

Java Application（Main 函数启动的java进程）

Maven：

<dependency>
         <groupId>com.alibaba</groupId>
         <artifactId>dubbo</artifactId>
         <version>2.5.5</version>
    </dependency>

四、配置生产者XML

五、my-provider工程

**(5.1) 将dubbo-api1 : 存放公共接口； 最终会打为jar包，供consumer和provider1引用。**

**pom.xml**

<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.hlx.dubbo</groupId>
    	<artifactId>my-provider</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<packaging>jar</packaging>
    
    	<name>my-provider</name>
    	<url>http://maven.apache.org</url>
    
    	<properties>
    		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    	</properties>
    
    	<dependencies>
    		<dependency>
    			<groupId>com.alibaba</groupId>
    			<artifactId>dubbo</artifactId>
    			<version>2.5.5</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.apache.zookeeper</groupId>
    			<artifactId>zookeeper</artifactId>
    			<version>3.4.8</version>
    		</dependency>
    
    		<dependency>
    			<groupId>com.github.sgroschupf</groupId>
    			<artifactId>zkclient</artifactId>
    			<version>0.1</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework</groupId>
    			<artifactId>spring-test</artifactId>
    			<version>4.3.10.RELEASE</version>
    		</dependency>
    		<dependency>
    			<groupId>junit</groupId>
    			<artifactId>junit</artifactId>
    			<version>4.12</version>
    		</dependency>
    	</dependencies>
    </project>

**(5.2) dubbo-properties**

dubbo.container=spring
    #set dubbo Sping load setting xmls
    dubbo.spring.config=classpath:spring-dubbo-provider.xml
    dubbo.protocol.name=dubbo
    dubbo.protocol.port=20880

**(5.3)spring-dubbo-provider.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">
    
    	
    	<dubbo:application name="my-provider" />
    
    	
    	<dubbo:registry id="zk1" address="127.0.0.1:2181"
    		protocol="zookeeper" />
    		
    	
    	<dubbo:protocol id="mydubbo" name="dubbo" port="20880" />
    	
    	
    	
    	
    	
    	<bean id="userService" class="com.hlx.provider.UserServiceImpl"/>
    	<dubbo:service interface="com.hlx.service.UserService" ref="userService"  />
    
    
    
    </beans>

**(5.4)UserServiceImpl实现接口的类**

public class UserServiceImpl implements UserService {
    
    	public String sayHello(String name) {
    		System.out.println("["
    				+ new SimpleDateFormat("HH:mm:ss").format(new Date())
    				+ "] Hello " + name + ", request from consumer: "
    				+ RpcContext.getContext().getRemoteAddress());
    		return "Hello " + name + ", response form provider: "
    				+ RpcContext.getContext().getLocalAddress();
    	}
    
    }

**（5.5）Main类**

package com.hlx.provider;
    
    /**
     * 该类是dubbo框架提供，作用是启动dubbo服务，dubbo会在启动服务时，
     * 读取classpath下一个名为dubbo.properties文件的属性值
     * 
     * @author Administrator
     * 
     */
    public class Main {
    	public static void main(String[] args) {
    		com.alibaba.dubbo.container.Main.main(args);
    	}
    }

**(5.6)启动zookeeper注册中心服务**

**(5.7)启动生产者**

**(5.8)启动zookeeper客户端查看服务是否被注册**
