2019独角兽企业重金招聘Python工程师标准>>> 
1、在 Service 工程中添加dubbo依赖的jar包。
<!-- dubbo相关 排除部分依赖-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
<exclusion>
<groupId>org.jboss.netty</groupId>
<artifactId>netty</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
</dependency>
<dependency>
<groupId>com.github.sgroschupf</groupId>
<artifactId>zkclient</artifactId>
</dependency>
2 在spring的配置文件中添加dubbo的约束，然后使用dubbo:service发布服务。
<?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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
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.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd">
<!-- 配置商品管理的service -->
<context:component-scan base-package="com.shi.service"></context:component-scan>
<!-- 使用dubbo发布服务 -->
<!-- 提供方应用信息，用于计算依赖关系 -->
<dubbo:application name="Graduation-manager" />
<dubbo:registry protocol="zookeeper" address="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.shi.service.ItemService" ref="itemServiceImp" />
</beans>
3 web 添加对dubbo的依赖。
<!-- dubbo相关 排除部分依赖-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
<exclusion>
<groupId>org.jboss.netty</groupId>
<artifactId>netty</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
</dependency>
<dependency>
<groupId>com.github.sgroschupf</groupId>
<artifactId>zkclient</artifactId>
</dependency>
4 修改springmvc.xml，在springmvc的配置文件中添加服务的引用。
<?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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
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.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd">
<!-- 配置扫描器 -->
<context:component-scan base-package="com.shi.controller" >
<!--
use-default-filters="false"
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
<context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> -->
</context:component-scan>
<!-- 配置springmvc的映射器和适配器 -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 配置映射器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- <property name="prefix" value="/WEB-INF/"></property> -->
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 配置我们的拦截器 -->
<!-- <mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<bean class="com.shi.interceptor.LoginInterceptor"></bean>
</mvc:interceptor>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<bean class="com.shi.interceptor.CheckInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors> -->
<!-- 引用dubbo服务 -->
<dubbo:application name="Graduation-manager-service"></dubbo:application>
<dubbo:registry protocol="zookeeper" address="127.0.0.1:2181"></dubbo:registry>
<dubbo:reference interface="com.shi.service.ItemService" id="itemService"></dubbo:reference>
</beans>
5 分别在web和service中添加服务器插件 并且启懂zookeeper 和 俩个服务器 就可以 访问我们的服务了
