3.2 配置离线约束 地址： http://code.alibabatech.com/schema/dubbo/dubbo.xsd 3.3 入门小 Demo 3.3.1 服务提供者开发 开发步骤： （1）创建 Maven工程（WAR）dubboxdemo-service，在 pom.xml中引入依赖

<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 [url=http://maven.apache.org/xsd/maven-4.0.0.xsd]http://maven.apache.org/xsd/maven-4.0.0.xsd[/url]">

（2）在工程的 webapps 下创建 WEB-INF 文件夹，创建 web.xml

return"itcast"; } } 注意：Service 注解与原来不同，需要引入 com.alibaba 包下的 （5）编写配置文件 在 src/main/resources 下创建 applicationContext-service.xml ,内容如下：

<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:mvc="http://www.springframework.org/schema/mvc"
 
xsi:schemaLocation="http://www.springframework.org/schema/beans [url=http://www.springframework.org/schema/beans/spring-beans.xsd]http://www.springframework.org/schema/beans/spring-beans.xsd[/url]
 
[url=http://www.springframework.org/schema/mvc]http://www.springframework.org/schema/mvc[/url] [url=http://www.springframework.org/schema/mvc/spring-mvc.xsd]http://www.springframework.org/schema/mvc/spring-mvc.xsd[/url]
 
[url=http://code.alibabatech.com/schema/dubbo]http://code.alibabatech.com/schema/dubbo[/url] [url=http://code.alibabatech.com/schema/dubbo/dubbo.xsd]http://code.alibabatech.com/schema/dubbo/dubbo.xsd[/url]
 
[url=http://www.springframework.org/schema/context]http://www.springframework.org/schema/context[/url] [url=http://www.springframework.org/schema/context/spring-context.xsd]http://www.springframework.org/schema/context/spring-context.xsd[/url]">
 
 
<dubbo:application  name="dubboxdemo-service"/>
 
<dubbo:registry  address="zookeeper://192.168.25.132:2181"/>
 
<dubbo:annotation  package="cn.itcast.dubboxdemo.service"  />
 
</beans>

注意：dubbo:annotation 用于扫描@Service 注解。 （6）测试运行 tomcat7:run
