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!
  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:
    <?xml version="1.0" encoding="UTF-8"?>

            <module>dubbo_consumer</module>
            <module>dubbo_provider</module>
        </modules>
    </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:
    <?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"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <parent>
            <artifactId>dubbo_demo</artifactId>
            <groupId>com.dubbo</groupId>
            <version>1.0-SNAPSHOT</version>
        </parent>
    
        <modelVersion>4.0.0</modelVersion>
    
        <artifactId>dubbo_api</artifactId>
    
        <packaging>jar</packaging>
    
    </project>
  5. 重复3、4步骤,创建dubbo_provider(服务生产者),对应的pom.xml文件:
    <?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"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <parent>
            <artifactId>dubbo_demo</artifactId>
            <groupId>com.dubbo</groupId>
            <version>1.0-SNAPSHOT</version>
        </parent>
        <modelVersion>4.0.0</modelVersion>
    
        <artifactId>dubbo_provider</artifactId>
    
        <dependencies>
            <dependency>
                <groupId>com.dubbo</groupId>
                <artifactId>dubbo_api</artifactId>
                <version>1.0-SNAPSHOT</version>
                <scope>compile</scope>
            </dependency>
        </dependencies>
    
    </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:
    <?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"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <parent>
            <artifactId>dubbo_demo</artifactId>
            <groupId>com.dubbo</groupId>
            <version>1.0-SNAPSHOT</version>
        </parent>
        <modelVersion>4.0.0</modelVersion>
    
        <artifactId>dubbo_consumer</artifactId>
    
        <dependencies>
            <dependency>
                <groupId>com.dubbo</groupId>
                <artifactId>dubbo_api</artifactId>
                <version>1.0-SNAPSHOT</version>
                <scope>compile</scope>
            </dependency>
        </dependencies>
    
    </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:
    package com.api.service;
    
    /**
     * 定义服务接口
     */
    public interface DemoService {
        String sayHello(String name);
    }
  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):
    package com.provider.service;
    
    import com.api.service.DemoService;
    
    public class DemoServiceImpl  implements DemoService {
        public String sayHello(String name) {
            return "Hello "+name;
        }
    }
  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:
    <?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">
    
        <!-- 提供方应用信息,用于计算依赖关系 -->
        <dubbo:application name="dubbo_provider"  />
    
        <!-- 使用zookeeper注册中心暴露服务地址 -->
        <dubbo:registry address="zookeeper://127.0.0.1:2181" />
    
        <!-- 用dubbo协议在20880端口暴露服务 -->
        <dubbo:protocol name="dubbo" port="20880" />
    
        <!-- 声明需要暴露的服务接口 -->
        <dubbo:service interface="com.api.service.DemoService" ref="demoService" />
    
        <!-- 接口实现类-->
        <bean id="demoService" class="com.provider.service.DemoServiceImpl"/>
    
    </beans>
    
    
    springmvc.xml如下:
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.springframework.org/schema/aop
            http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-4.0.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util-4.0.xsd"
           default-autowire="byName">
    
        <aop:aspectj-autoproxy />
        <context:component-scan base-package="com" />
        <import resource="classpath:dubbo-provider.xml" />
    </beans>
    再在该工程下写一个测试类,后面测试用到:
    package com.provider.test;
    
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import java.io.IOException;
    
    public class ProviderTest {
        public static void main(String[] args) {
            ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:springmvc.xml");
            context.start();
    
            System.out.println("Dubbo provider start...");
    
            try {
                System.in.read();   // 按任意键退出
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
  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:
    <?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 ">
        <!-- 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 -->
        <dubbo:application name="dubbo_consumer" />
        <!-- 使用multicast广播注册中心暴露发现服务地址 -->
        <dubbo:registry  protocol="zookeeper" address="zookeeper://127.0.0.1:2181" />
        <!-- 生成远程服务代理,可以和本地bean一样使用demoService -->
        <dubbo:reference id="demoService" interface="com.api.service.DemoService" />
    </beans>
    
    springmvc.xml:
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.springframework.org/schema/aop
            http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-4.0.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util-4.0.xsd"
           default-autowire="byName">
    
        <aop:aspectj-autoproxy />
        <context:component-scan base-package="com" />
        <import resource="classpath:/dubbo-consumer.xml" />
    </beans>
  12. 然后写消费者的测试
    package com.consumer;
    
    import com.api.service.DemoService;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import java.io.IOException;
    
    public class ConsumerTest {
        public static void main(String[] args) {
            ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "classpath:springmvc.xml" });
    
            context.start();
            DemoService demoService = (DemoService) context.getBean("demoService");
    
            System.out.println(demoService.sayHello("哈哈哈"));
            try {
                System.in.read();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
  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:
