生产者：

 pom.xml需要依赖的：

<properties>
    <spring.version>3.2.4.RELEASE</spring.version>
</properties>

<dependencies>
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>dubbo</artifactId>
        <version>2.5.3</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <!--dubbo注册中心-->
    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>3.4.6</version>
    </dependency>
    <!--zookeeper客户端-->
    <dependency>
        <groupId>com.github.sgroschupf</groupId>
        <artifactId>zkclient</artifactId>
        <version>0.1</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring.version}</version>
    </dependency>
</dependencies>

Service实现类：

@com.alibaba.dubbo.config.annotation.Service
@Service
public class UserServiceImpl implements UserService {
    public User login(String loginName, String passworld) {
        if("lalala".equals(loginName)&&"123".equals(passworld)){
             User user = new User("yinchong",23,"nam");
             return user;
        }
        return null;
    }
}

applicationContext.xml的配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       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://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://code.alibabatech.com/schema/dubbo
        http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <context:component-scan base-package="cn.itcast.service"/>
    <dubbo:annotation package="cn.itcast.service"></dubbo:annotation>

    <!-- 提供方应用信息，用于计算依赖关系 -->
    <dubbo:application name="hello-provider"  />

    <!-- 使用multicast广播注册中心暴露服务地址 -->
    <dubbo:registry address="zookeeper://192.168.2.201:2181?backup=192.168.2.202:2181,192.168.2.203:2181" />


    <!-- 用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" host="192.168.2.100" port="20888" />

    <!-- 声明需要暴露的服务接口 -->
   <!-- <dubbo:service interface="cn.itcast.service.UserService" ref="userService" />-->

    <!-- 和本地bean一样实现服务 -->
   <!-- <bean id="userService" class="cn.itcast.service.impl.UserServiceImpl" />-->

</beans>

启动类：

public class StartUtils {
    public static void main(String[] args) throws IOException {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        context.start();
        Reader reader = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("程序已经启动");
        int line = reader.read();
    }
}

消费者：

pom.xml和上面生产者一样

主要是它的配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       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://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-4.0.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="hello-consumer" />

    <!-- 使用multicast广播注册中心暴露发现服务地址 -->
    <dubbo:registry address="zookeeper://192.168.2.201:2181?backup=192.168.2.202:2181,192.168.2.203:2181" />

    <!-- 生成远程服务代理，可以和本地bean一样使用demoService -->
    <dubbo:reference id="userService" interface="cn.itcast.service.UserService" url="dubbo://192.168.2.100:20888" />

</beans>

dubbo的admin的配置是，它主要修改的是dubbo.properties

dubbo.registry.address=zookeeper://192.168.2.201:2181?backup=192.168.2.202:2181,192.168.2.203:2181
