这个博客是在https://blog.csdn.net/Crazer_cy/article/details/80397649篇文章上的基础上，自己学习用的。

1. Zookeeper为dubbo的注册中心，dubbo服务的生产者和消费者都需要在Zookeeper进行注册；
2. 下载zookeeper压缩包并解压；
3. 进入conf目录将 zoo_sample.cfg 改名为 zoo.cfg；
4. 进入bin目录双击zkServer.cmd，若启动成功，则windows单机版zookeeper搭建成功
5. 使用duboo-admin 

1. 使用IntelliJ IDEA搭建Dubbo:创建一个maven空项目，作为项目的父工程

   

2. 在pom.xml添加以下公共的依赖：

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

   114.   <module>dubbo_provider </module>
   115.   </modules>
   116.   </project>

3. 在刚才创建的dubbo_demo下创建一个新的Module:dubbo_api（服务接口）

4. dubbo_api的pom.xml文件如下：

   1.   <?xml version="1.0" encoding="UTF-8"?>
   2.   <project xmlns="http://maven.apache.org/POM/4.0.0"
   3.   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
   4.   xsi:schemaLocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   5.   <parent>
   6.   <artifactId>dubbo_demo </artifactId>
   7.   <groupId>com.dubbo </groupId>
   8.   <version>1.0-SNAPSHOT </version>
   9.   </parent>
   10.    
   11.   <modelVersion>4.0.0 </modelVersion>
   12.    
   13.   <artifactId>dubbo_api </artifactId>
   14.    
   15.   <packaging>jar </packaging>
   16.    
   17.   </project>

5. 重复3、4步骤，创建dubbo_provider（服务生产者）,对应的pom.xml文件：

   1.   <?xml version="1.0" encoding="UTF-8"?>
   2.   <project xmlns="http://maven.apache.org/POM/4.0.0"
   3.   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
   4.   xsi:schemaLocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   5.   <parent>
   6.   <artifactId>dubbo_demo </artifactId>
   7.   <groupId>com.dubbo </groupId>
   8.   <version>1.0-SNAPSHOT </version>
   9.   </parent>
   10.   <modelVersion>4.0.0 </modelVersion>
   11.    
   12.   <artifactId>dubbo_provider </artifactId>
   13.    
   14.   <dependencies>
   15.   <dependency>
   16.   <groupId>com.dubbo </groupId>
   17.   <artifactId>dubbo_api </artifactId>
   18.   <version>1.0-SNAPSHOT </version>
   19.   <scope>compile </scope>
   20.   </dependency>
   21.   </dependencies>
   22.    
   23.   </project>

6. 再重复3、4步骤，创建dubbo_consumer（服务消费者），对应pom.xml文件如下：

   1.   <?xml version="1.0" encoding="UTF-8"?>
   2.   <project xmlns="http://maven.apache.org/POM/4.0.0"
   3.   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
   4.   xsi:schemaLocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   5.   <parent>
   6.   <artifactId>dubbo_demo </artifactId>
   7.   <groupId>com.dubbo </groupId>
   8.   <version>1.0-SNAPSHOT </version>
   9.   </parent>
   10.   <modelVersion>4.0.0 </modelVersion>
   11.    
   12.   <artifactId>dubbo_consumer </artifactId>
   13.    
   14.   <dependencies>
   15.   <dependency>
   16.   <groupId>com.dubbo </groupId>
   17.   <artifactId>dubbo_api </artifactId>
   18.   <version>1.0-SNAPSHOT </version>
   19.   <scope>compile </scope>
   20.   </dependency>
   21.   </dependencies>
   22.    
   23.   </project>

7. 最后项目结构如下：

   

8. 框架搭建起来之后，开始写代码和配置文件，首先是dubbo_api：需要定义服务接口：

   1.   package com.api.service;
   2.    
   3.   /**
   4.   * 定义服务接口
   5.   */
   6.   public interface DemoService {
   7.   String sayHello(String name);
   8.   }

9. 然后再dubbo_provider中实现上述接口（由于在pom.xml文件中，将dubbo_api作为依赖，故能引入上述接口）：

   1.   package com.provider.service;
   2.    
   3.   import com.api.service.DemoService;
   4.    
   5.   public class DemoServiceImpl implements DemoService {
   6.   public String sayHello(String name) {
   7.   return "Hello "+name;
   8.   }
   9.   }

10. dubbo_provider项目中的resource文件包含dubbo-provider.xml和springmvc.xml配置文件，其中dubbo-provider.xml如下：

    1.   <?xml version="1.0" encoding="UTF-8"?>
    2.   <beans xmlns="http://www.springframework.org/schema/beans"
    3.   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
    4.   xmlns:dubbo= "http://code.alibabatech.com/schema/dubbo"
    5.   xsi:schemaLocation= "http://www.springframework.org/schema/beans
    6.   http://www.springframework.org/schema/beans/spring-beans.xsd
    7.   http://code.alibabatech.com/schema/dubbo
    8.   http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    9.    
    10.   <!-- 提供方应用信息，用于计算依赖关系 -->
    11.   <dubbo:application name="dubbo_provider" />
    12.    
    13.   <!-- 使用zookeeper注册中心暴露服务地址 -->
    14.   <dubbo:registry address="zookeeper://127.0.0.1:2181" />
    15.    
    16.   <!-- 用dubbo协议在20880端口暴露服务 -->
    17.   <dubbo:protocol name="dubbo" port="20880" />
    18.    
    19.   <!-- 声明需要暴露的服务接口 -->
    20.   <dubbo:service interface="com.api.service.DemoService" ref="demoService" />
    21.    
    22.   <!-- 接口实现类-->
    23.   <bean id="demoService" class="com.provider.service.DemoServiceImpl"/>
    24.    
    25.   </beans>
    26.    
    springmvc.xml如下：
    1.   <?xml version="1.0" encoding="UTF-8"?>
    2.   <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
    3.   xmlns:context= "http://www.springframework.org/schema/context"
    4.   xmlns:util= "http://www.springframework.org/schema/util" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
    5.   xsi:schemaLocation= "http://www.springframework.org/schema/aop
    6.   http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
    7.   http://www.springframework.org/schema/beans
    8.   http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    9.   http://www.springframework.org/schema/context
    10.   http://www.springframework.org/schema/context/spring-context-4.0.xsd
    11.   http://www.springframework.org/schema/util
    12.   http://www.springframework.org/schema/util/spring-util-4.0.xsd"
    13.   default-autowire= "byName">
    14.    
    15.   <aop:aspectj-autoproxy />
    16.   <context:component-scan base-package="com" />
    17.   <import resource="classpath:dubbo-provider.xml" />
    18.   </beans>

    再在该工程下写一个测试类，后面测试用到：

    1.   package com.provider.test;
    2.    
    3.   import org.springframework.context.support.ClassPathXmlApplicationContext;
    4.    
    5.   import java.io.IOException;
    6.    
    7.   public class ProviderTest {
    8.   public static void main(String[] args) {
    9.   ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( "classpath:springmvc.xml");
    10.   context.start();
    11.    
    12.   System.out.println( "Dubbo provider start...");
    13.    
    14.   try {
    15.   System.in.read(); // 按任意键退出
    16.   } catch (IOException e) {
    17.   e.printStackTrace();
    18.   }
    19.   }
    20.   }

11. 接下来开始写消费者——dubbo_consumer的代码和配置文件：resource中的dubbo-consumer.xml:

    1.   <?xml version="1.0" encoding="UTF-8"?>
    2.   <beans xmlns="http://www.springframework.org/schema/beans"
    3.   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo= "http://code.alibabatech.com/schema/dubbo"
    4.   xsi:schemaLocation= "http://www.springframework.org/schema/beans
    5.   http://www.springframework.org/schema/beans/spring-beans.xsd
    6.   http://code.alibabatech.com/schema/dubbo
    7.   http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">
    8.   <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
    9.   <dubbo:application name="dubbo_consumer" />
    10.   <!-- 使用multicast广播注册中心暴露发现服务地址 -->
    11.   <dubbo:registry protocol="zookeeper" address="zookeeper://127.0.0.1:2181" />
    12.   <!-- 生成远程服务代理，可以和本地bean一样使用demoService -->
    13.   <dubbo:reference id="demoService" interface="com.api.service.DemoService" />
    14.   </beans>
    springmvc.xml:
    1.   <?xml version="1.0" encoding="UTF-8"?>
    2.   <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
    3.   xmlns:context= "http://www.springframework.org/schema/context"
    4.   xmlns:util= "http://www.springframework.org/schema/util" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
    5.   xsi:schemaLocation= "http://www.springframework.org/schema/aop
    6.   http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
    7.   http://www.springframework.org/schema/beans
    8.   http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    9.   http://www.springframework.org/schema/context
    10.   http://www.springframework.org/schema/context/spring-context-4.0.xsd
    11.   http://www.springframework.org/schema/util
    12.   http://www.springframework.org/schema/util/spring-util-4.0.xsd"
    13.   default-autowire= "byName">
    14.    
    15.   <aop:aspectj-autoproxy />
    16.   <context:component-scan base-package="com" />
    17.   <import resource="classpath:/dubbo-consumer.xml" />
    18.   </beans>

12. 然后写消费者的测试

    1.   package com.consumer;
    2.    
    3.   import com.api.service.DemoService;
    4.   import org.springframework.context.support.ClassPathXmlApplicationContext;
    5.    
    6.   import java.io.IOException;
    7.    
    8.   public class ConsumerTest {
    9.   public static void main(String[] args) {
    10.   ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( new String[] { "classpath:springmvc.xml" });
    11.    
    12.   context.start();
    13.   DemoService demoService = (DemoService) context.getBean( "demoService");
    14.    
    15.   System.out.println(demoService.sayHello( "哈哈哈"));
    16.   try {
    17.   System.in.read();
    18.   } catch (IOException e) {
    19.   e.printStackTrace();
    20.   }
    21.   }
    22.   }

13. 到现在整个代码就开发完成了，按照先后顺序，首先启动Zookeeper：zkServer.cmd      然后启动服务生产者测试类，最后启动服务消费者的测试类，当控制台输出以下结果，则代表成功。

    服务生产者测试类控制台输出：
    服务消费者测试了控制台输出：

使用dubbo-admin管理平台查看运行情况。
