Dubbo-002

1.引入Dubbo相关依赖：

        <dubbo.version>2.5.3</dubbo.version>
        <zookeeper.version>3.4.7</zookeeper.version>
        <zkclient.version>0.1</zkclient.version>
        
        <!-- dubbo相关 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>${dubbo.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>${zookeeper.version}</version>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>${zkclient.version}</version>
        </dependency>

2.在service服务层发布Dubbo服务：（记得去掉与spring冲突的jar包）

        applicationContext-service.xml：
        
            <!-- 发布dubbo服务 -->
            <!-- 提供方应用信息，用于计算依赖关系 -->
            <dubbo:application name="taotao-manager" />
            <!-- 注册中心的地址 -->
            <dubbo:registry protocol="zookeeper" address="192.168.132.128:2181" />
            <!-- 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.taotao.service.ItemService"
                ref="itemServiceImpl" />
        pom.xml:

            <!-- dubbo相关 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <exclusions>
                <exclusion>
                    <artifactId>spring</artifactId>
                    <groupId>org.springframework</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>netty</artifactId>
                    <groupId>org.jboss.netty</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
        </dependency>

3.在web视图层引用Dubbo服务：

springmvc.xml：


    <!-- 引用dubbo服务 -->
    <dubbo:application name="taotao-manager-web" />
    <dubbo:registry protocol="zookeeper" address="192.168.132.128:2181" />
    <dubbo:reference interface="com.taotao.service.ItemService"
        id="itemService" />


pom.xml：

<!-- dubbo相关 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <exclusions>
                <exclusion>
                    <artifactId>spring</artifactId>
                    <groupId>org.springframework</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>netty</artifactId>
                    <groupId>org.jboss.netty</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
        </dependency>
