dubbo（二）发布dubbo服务

1.pom.xml中添加相关jar包

<!-- dubbo相关jar包 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
</dependency>
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
</dependency>
<dependency>
<groupId>com.github.sgroschupf</groupId>
<artifactId>zkclient</artifactId>
</dependency>

2.配置spring的配置文件中添加dubbo相关配置：

发布dubbo服务相关配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> 
<!-- 配置包扫描器，扫描所有带@Service注解的类 -->
<context:component-scan base-package="com.milan.service"/>

<!-- 发布dubbo服务 -->
<!-- 提供方应用信息，用于计算依赖关系 -->
<dubbo:application name="dubbo-demo" />
<!-- 注册中心的地址 -->
<dubbo:registry protocol="zookeeper" address="192.168.1.1:2181" />
<!-- 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.milan.service.ItemService" ref="itemServiceImpl" timeout="300000"/>
</beans>

引用dubbo服务相关配置：

<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> 
<!-- 配置注解驱动 -->
<mvc:annotation-driven />
<!-- 视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 配置包扫描器，扫描@Controller注解的类 -->
<context:component-scan base-package="com.milan.controller"/>
<!-- 配置资源映射 -->
<mvc:resources location="/css/" mapping="/css/**"/>
<mvc:resources location="/js/" mapping="/js/**"/>
<!-- 引用dubbo服务 -->
<dubbo:application name="dubbo-demo"/>
<dubbo:registry protocol="zookeeper" address="192.168.1.1:2181"/>
<dubbo:reference interface="com.milan.service.ItemService" id="itemService" />

</beans>

3.启动dubbo相关

启动zookeeper

./zkServer.sh start

关闭Linux防火墙

service iptables stop
