Spring Dubbo整合开发

spring-dubbo-api    服务的接口

spring-dubbo-domain  接口的实现，也是dubbo的生产者

spring-dubbo-web 接口的调用者，消费者

1 spring-dubbo-api  

接口：UserService

package spring.dubbo.api.service;public interface UserService {public String select(String id);}

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>spring.dubbo.test</groupId>  <artifactId>spring-dubbo-api</artifactId>  <version>0.0.1-SNAPSHOT</version></project>

maven创建的时候选的打包方式是jar

2 spring-dubbo-domain

pom.xml 引入spring-dubbo-api 接口包，因为要实现接口，dubbo只能调用接口，所以会有spring-dubbo-api ，没有直接使用类；dubbo zookeeper包 spring包

<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>spring.dubbo.test</groupId><artifactId>spring-dubbo-domain</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><java.version>1.7</java.version><spring.version>3.2.8.RELEASE</spring.version><commons.version>2.2</commons.version></properties><dependencies><!-- 使用dubbo的接口 --><dependency><groupId>spring.dubbo.test</groupId><artifactId>spring-dubbo-api</artifactId><version>0.0.1-SNAPSHOT</version></dependency><!-- junit --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.7</version><type>jar</type><scope>test</scope></dependency><!-- dubbo,zookeeper包 --><dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.4.10</version><exclusions><exclusion><groupId>org.springframework</groupId><artifactId>spring</artifactId></exclusion></exclusions></dependency><dependency><groupId>com.101tec</groupId><artifactId>zkclient</artifactId><version>0.4</version></dependency><!-- spring 包 --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc-portlet</artifactId><version>${spring.version}</version></dependency></dependencies></project>

UserServiceImpl

package spring.dubbo.domain.service;import org.springframework.stereotype.Service;import spring.dubbo.api.service.UserService;@Service("userService")public class UserServiceImpl implements UserService {public String select(String id) {return "{name:这是dubbo调用的服务"+",id:"+id+"}";}}

user-provider.xml

消费者配置，添加配置后有可能xml会报错，需要下载 dubbo.xsd，我的在 C:\Users\Administrator\Desktop\dubbo\dubbo.xsd，按照window-preferences-xml Catalog-Add

LOCATION放dubbo.xsd的地址，如下

<?xml version="1.0" encoding="UTF-8"?><beans  xmlns="http://www.springframework.org/schema/beans"xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans          http://www.springframework.org/schema/beans/spring-beans-3.0.xsd            http://code.alibabatech.com/schema/dubbo          http://code.alibabatech.com/schema/dubbo/dubbo.xsd">                  <!-- 提供方应用名称信息，这个相当于起一个名字，我们dubbo管理页面比较清晰是哪个应用暴露出来的 --><dubbo:application name="spring-dubbo-domain"/><!-- 提供方应用名称信息，这个相当于起一个名字，我们dubbo管理页面比较清晰是哪个应用暴露出来的 -->        <!-- 使用zookeeper注册中心暴露服务地址 --><dubbo:registry  id="zk1" address="192.168.150.129:2181" protocol="zookeeper" />  <!-- 使用multicast广播注册中心暴露服务地址 -->      <!--<dubbo:registry address="multicast://224.5.6.7:1234" /> -->      <!-- 用dubbo协议在20886端口暴露服务 -->       <dubbo:protocol id="mydubbo"  name="dubbo" port="20886" />        <dubbo:provider registry="zk1"  protocol="mydubbo"/>                   <!-- 声明需要暴露的服务接口 -->      <dubbo:service interface="spring.dubbo.api.service.UserService"   ref="userService" />  </beans>

dubbo注册中心的地址，为zookeeper安装时候配置的，默认本机ip：2181

web.xml

说明：maven创建web项目:创建项目时候选择war包，创建好后，随便在一个其他web项目copy出WEB-INF，放在自己的webapp下即可；

3 spring-dubbo-web

UserController

这是一个测试类，spring容器加载完毕，自动执行该方法，这个方法里注入了dubbo提供的接口UserService,如果调用成功说明dubbo已经被成功调用；当然这个类需要在spring的配置里添加<bean class="spring.dubbo.web.controller.UserController"/> ；

package spring.dubbo.web.controller;import java.util.concurrent.TimeUnit;import javax.annotation.Resource;import org.springframework.context.ApplicationListener;import org.springframework.context.event.ContextRefreshedEvent;import spring.dubbo.api.service.UserService;public class UserController implements ApplicationListener<ContextRefreshedEvent>{@Resourceprivate UserService userService;public void onApplicationEvent(ContextRefreshedEvent event) {if(event.getApplicationContext().getParent() == null){System.out.println("这是消费端的应用");System.out.println(userService.select("123"));;}}}

测试：测试的时候可以在eclipse启动2个tomcat，不要放在1个里面,2个tomcat的3个端口参数不能相同，否则无法启动。

修改端口参数

测试结果：

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
这是消费端的应用
