Dubbo、ZooKeeper、Moven project安装设置好后,我们就要应用Dubbo来实现服务的部署
Dubbo 服务分为服务提供端与消费端
1、下载dubbo.xsd文件,地址:http://download.csdn.net/detail/zp522123428/8036977
也可以在下载的dubbo.jar包里找到。
打开Eclipse,然后windows->preferrence->xml->xmlcatalog add->catalog entry ->file system
选择刚刚下载的文件路径,修改key值: http://code.alibabatech.com/schema/dubbo/dubbo.xsd
在pom.xml中配置dubbo,要注意dubbo默认依赖的是spring2.5版本
会跟当前系统使用的spring版本冲突,所以做如下配置
<properties>
<dubbo.version>2.5.3</dubbo.version>
<zookeeper.version>3.4.6</zookeeper.version>
</properties>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>${dubbo.version}</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>${zookeeper.version}</version>
</dependency>
<dependency>
<groupId>com.github.sgroschupf</groupId>
<artifactId>zkclient</artifactId>
<version>0.1</version>
</dependency>
2、dubbo服务提供端配置文件内容:
<?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: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://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<!-- 提供方应用名称信息,这个相当于起一个名字,我们dubbo管理页面比较清晰是哪 个应用暴露出来的 -->
<dubbo:application name="dubbo_provider"></dubbo:application>
<!-- 使用zookeeper注册中心暴露服务地址 -->
<dubbo:registry address="zookeeper://127.0.0.1:2181" check="false" subscribe="false" register=""></dubbo:registry>
<!-- 要暴露的服务接口 -->
<dubbo:service interface="cn.test.dubbo.registry.service.TestRegistryService"ref="testRegistryService" />
</beans>
3、dubbo服务消费端配置文件内容:
<?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: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://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<dubbo:application name="dubbo_consumer2"></dubbo:application>
<!-- 使用zookeeper注册中心暴露服务地址 -->
<dubbo:registry address="zookeeper://10.10.0.126:2181" check="false"></dubbo:registry>
<!-- 要引用的服务 -->
<dubbo:reference interface="cn.test.dubbo.registry.service.TestRegistryService" id="testRegistryService"></dubbo:reference>
</beans>
