2、生产端

2.1、项目结构

2.2、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.mujourney</groupId>    <artifactId>dubbo-provider</artifactId>    <version>0.0.1-SNAPSHOT</version>    <name>dubbo-provider</name>    <url>http://maven.apache.org</url>    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    </properties>    <dependencies>        <dependency>            <groupId>com.mujourney</groupId>            <artifactId>dubbo-service</artifactId>            <version>0.0.1-SNAPSHOT</version>        </dependency>        <dependency>            <groupId>org.apache.zookeeper</groupId>            <artifactId>zookeeper</artifactId>            <version>3.4.6</version>        </dependency>        <dependency>            <groupId>com.alibaba</groupId>            <artifactId>dubbo</artifactId>            <version>2.5.3</version>        </dependency>        <dependency>            <groupId>com.101tec</groupId>            <artifactId>zkclient</artifactId>            <version>0.5</version>        </dependency>    </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-compiler-plugin</artifactId>                <version>3.3</version>                <configuration>                    <source>1.7</source>                    <target>1.7</target>                    <verbose>true</verbose>                </configuration>            </plugin>        </plugins>    </build></project>

 2.3、UserServiceImpl.java

package com.mujourney.service;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import com.alibaba.dubbo.config.annotation.Service;@Service(interfaceName="com.mujourney.service.UserService",timeout=10000)public class UserServiceImpl implements UserService {    public Map<String, Object> findById(int id) {        return get(id);    }    public List<Map<String, Object>> queryList() {        List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();        for (int i = 1; i <= 10; i++) {            list.add(get(i));        }        return list;    }    private Map<String, Object> get(int id) {        Map<String, Object> res = new HashMap<String, Object>();        res.put("id", id);        res.put("name", "1");        res.put("type", "1");        res.put("date", "1");        return res;    }}

2.4、StartServer.java

package com.mujourney.service;import java.util.concurrent.TimeUnit;import org.springframework.context.support.ClassPathXmlApplicationContext;public class StartServer {    public static void main(String[] args) {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(                new String[] { "application-provider.xml" });        context.start();        System.out.println("=========dubbo生产者启动完毕========");        try {            TimeUnit.HOURS.sleep(1l);        } catch (InterruptedException e) {            e.printStackTrace();        }    }}

2.5、application-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-4.0.xsd          http://code.alibabatech.com/schema/dubbo           http://code.alibabatech.com/schema/dubbo/dubbo.xsd">        <!-- 指定dubbo的服务名称 -->      <dubbo:application name="my_provider" />            <!-- 使用multicast广播注册中心暴露服务地址 -->      <!-- <dubbo:registry protocol="zookeeper" address="zookeeper://192.168.18.25:2181" /> -->        <dubbo:registry protocol="zookeeper" address="zookeeper://192.168.0.4:2181" />          <!-- 用dubbo协议在20880端口暴露服务 -->      <dubbo:protocol name="dubbo" port="20880" />        <!-- 具体的实现bean -->     <!--  <bean id="userService" class="com.mujourney.service.UserServiceImpl" />   -->      <!-- 声明需要暴露的服务接口 -->      <!-- <dubbo:service interface="com.mujourney.service.UserService" ref="userService" />  -->         <!-- 扫描注解包路径，多个包用逗号分隔，不填pacakge表示当前ApplicationContext中所有的类 -->   <dubbo:annotation package="com.mujourney.service"></dubbo:annotation></beans>  

因为使用注解来创建服务，所以就把生成者的配置文件创建UserServiceImpl类和指定接口给注释了

3、消费端 

3.1 、项目结构

3.2、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.mujourney</groupId>    <artifactId>dubbo-consumer</artifactId>    <version>0.0.1-SNAPSHOT</version>    <name>dubbo-consumer</name>    <url>http://maven.apache.org</url>    <properties>        <spring.version>3.2.4.RELEASE</spring.version>        <junit.version>4.8.2</junit.version>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    </properties>    <dependencies>        <dependency>            <groupId>com.alibaba</groupId>            <artifactId>dubbo</artifactId>            <version>2.5.3</version>            <exclusions>                  <exclusion>                      <artifactId>spring</artifactId>                      <groupId>org.springframework</groupId>                  </exclusion>              </exclusions>          </dependency>         <dependency>            <groupId>org.apache.zookeeper</groupId>            <artifactId>zookeeper</artifactId>            <version>3.4.6</version>        </dependency>        <dependency>            <groupId>com.github.sgroschupf</groupId>            <artifactId>zkclient</artifactId>            <version>0.1</version>        </dependency>        <!-- 关联dubbo-service工程源码 -->         <dependency>            <groupId>com.mujourney</groupId>            <artifactId>dubbo-service</artifactId>            <version>0.0.1-SNAPSHOT</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-core</artifactId>            <version>${spring.version}</version>            <type>jar</type>            <optional>false</optional>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-beans</artifactId>            <version>${spring.version}</version>            <type>jar</type>            <optional>false</optional>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context</artifactId>            <version>${spring.version}</version>            <type>jar</type>            <optional>false</optional>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-test</artifactId>            <version>${spring.version}</version>            <scope>test</scope>            <type>jar</type>        </dependency>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>${junit.version}</version>            <scope>test</scope>            <type>jar</type>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context-support</artifactId>            <version>3.0.5.RELEASE</version>            <optional>false</optional>        </dependency>            </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-compiler-plugin</artifactId>                <version>3.3</version>                <configuration>                    <source>1.7</source>                    <target>1.7</target>                    <verbose>true</verbose>                </configuration>            </plugin>        </plugins>    </build></project>

3.3、application-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-4.0.xsd          http://code.alibabatech.com/schema/dubbo           http://code.alibabatech.com/schema/dubbo/dubbo.xsd">        <!-- 指定生成者 -->      <dubbo:application name="my_provider" />        <!-- 使用multicast广播注册中心暴露服务地址 -->      <dubbo:registry address="zookeeper://192.168.0.4:2181" />          <!-- 扫描注解包路径，多个包用逗号分隔，不填package表示扫描当前ApplicationContext中的所有类 -->    <dubbo:annotation package="com.mujourney.service"></dubbo:annotation>   </beans>

3.4、ClientTest.java

package com.mujourney.service;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.stereotype.Component;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.alibaba.dubbo.config.annotation.Reference;@Component@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations={"/application-consumer.xml"})public class ClientTest {        @Reference(interfaceName="com.mujourney.service.UserService")    private UserService uservice;        @Test    public void pors()  {        System.out.println(uservice.findById(1));    }}

4、服务的接口端

4.1、项目结构

4.2 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.mujourney</groupId>  <artifactId>dubbo-service</artifactId>  <version>0.0.1-SNAPSHOT</version>    <dependencies>          <dependency>              <groupId>junit</groupId>              <artifactId>junit</artifactId>              <version>4.10</version>              <scope>test</scope>          </dependency>      </dependencies>        <build>          <plugins>              <plugin>                  <groupId>org.apache.maven.plugins</groupId>                  <artifactId>maven-compiler-plugin</artifactId>                  <version>3.3</version>                  <configuration>                      <source>1.7</source>                      <target>1.7</target>                      <verbose>true</verbose>                  </configuration>              </plugin>                <plugin>                  <groupId>org.apache.maven.plugins</groupId>                  <artifactId>maven-source-plugin</artifactId>                  <version>2.4</version>                  <executions>                      <execution>                          <id>attach-sources</id>                          <phase>verify</phase>                          <goals>                              <goal>jar-no-fork</goal>                          </goals>                      </execution>                  </executions>              </plugin>            </plugins>      </build>  </project>

4.3、UserService.java

package com.mujourney.service;import java.util.List;import java.util.Map;public interface UserService {     public Map<String, Object> findById(int id);            public List<Map<String, Object>> queryList();  }

之所以有一个服务的接口端，因为生产者和消费者都要用到接口，把接口单独作为maven的java项目可以打jar包放到私库给生产端和消费端同时使用。
