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[/code] 
<!-- 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[/code] <!-- 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>
