dubbo 服務中間件 的使用

一、在 Service 工程中添加dubbo依賴的jar包。

<!-- dubbo相關  排除部分依賴-->
<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的約束，而後使用dubbo:service發佈服務。

<?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發佈服務 -->
	<!-- 提供方應用信息，用於計算依賴關係 -->
	<dubbo:application name="Graduation-manager" />
	<dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" />
	<!-- 用dubbo協議在20880端口暴露服務 -->
	<dubbo:protocol name="dubbo" port="20880" />
	<!-- 聲明須要暴露的服務接口 -->
	<dubbo:service interface="com.shi.service.ItemService" ref="itemServiceImp" />

	
</beans>

3 web 添加對dubbo的依賴。

<!-- dubbo相關  排除部分依賴-->
<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務的引用。

<?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">
	
	<!-- 配置掃描器 -->
	<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的映射器和適配器 -->
  	<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>
	
	<!-- 配置咱們的攔截器 -->
	<!-- <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服務 -->
	<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 分別在web和service中添加服務器插件 而且啓懂zookeeper 和 倆個服務器 就能夠 訪問咱們的服務了
