使用dubbo与zookeeper搭建面向服务的架构工程

一、在服务的pom文件中加入jar包，dubbo底层依赖低版本的spring，需要排除

<!-- dubbo相关 -->
		<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>

在spring配置文件中添加dubbo的约束，使用dubbo:service发布服务

xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" 

http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd

<!-- 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="e3-manager" />
	<dubbo:registry protocol="zookeeper"
		address="192.168.25.154:2181,192.168.25.154:2182,192.168.25.154:2183" />
	<!-- 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="cn.e3mall.service.ItemService" ref="itemServiceImpl" />

二、在调用的pom文件中加入jar包

<!-- dubbo相关 -->
		<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>

在调用端springmvc中加入dubbo的约束

xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" 

http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd

	<!-- 引用dubbo服务 -->
	<dubbo:application name="e3-manager-web"/>
	<dubbo:registry protocol="zookeeper" address="192.168.25.154:2181,192.168.25.154:2182,192.168.25.154:2183"/>	
	<dubbo:reference interface="cn.e3mall.service.ItemService" id="itemService" />

在web工程中添加tomcat插件

<build>
		<plugins>
			<!-- 配置Tomcat插件 -->
			<plugin>
				<groupId>org.apache.tomcat.maven</groupId>
				<artifactId>tomcat7-maven-plugin</artifactId>
				<configuration>
					<path>/</path>
					<port>8081</port>
				</configuration>
			</plugin>
		</plugins>
	</build>
