dubbo zookeeper简单的provide 和cosumer

 

准备工作

 

1、两个mave项目，一个provider 一个cosumer，

 

2、搭建好spring

 

1、提供者

 

1、pom依赖

 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.wpb.dubbo</groupId>
<artifactId>dubbo-provide</artifactId>
<version>0.0.1-SNAPSHOT</version>

<properties>
<spring.version>4.1.3.RELEASE</spring.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.4.10</version>
<exclusions>
<exclusion>
<artifactId>spring</artifactId>
<groupId>org.springframework</groupId>
</exclusion>
</exclusions>
</dependency>

<dependency>
<groupId>com.101tec</groupId>
<artifactId>zkclient</artifactId>
<version>0.3</version>
</dependency>
</dependencies>
</project>

 

2、接口和实现类

 

1、接口

 


public interface DubboProvide {

void sayHello();
}

 

 

2、实现类

 


public class DubboProvideImpl implements DubboProvide {

public void sayHello() {
System.out.println("this is my first dubbo program");
}

}

 

 

3、spring 配置dubbo zookeeper

 

1、<dubbo:application 给服务器起的名字

2、 <dubbo:registry用zookeeper注册服务中心暴露服务地址 –

3、 <dubbo:service 提供服务的接口，以及实现类进行注入（有点类似webservice）

 

<?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  
        ">      
<!-- 给dubbo服务者起个名 -->  
<dubbo:application name="productor"/>  

<!-- 用zookeeper注册服务中心暴露服务地址 -->  
<dubbo:registry protocol="zookeeper" address="zookeeper://127.0.0.1:2181"/>  
<!-- 暴露dubbo的通信端口 -->  
<dubbo:protocol name="dubbo" port="20880"/>  

<!-- 提供服务的实现类 -->  
<bean id="bubboProdutor" class="com.dubbo.service.impl.DubboProvideImpl"></bean>  
<!-- 给消费者提供服务的接口 -->  
<dubbo:service ref="bubboProdutor" interface="com.dubbo.service.DubboProvide"></dubbo:service>  
       </beans>

 

4、加载这个spring配置文件

 

public class DubboProvideStart {

public static void main(String[] args) throws Exception {  
ClassPathXmlApplicationContext cfg = new ClassPathXmlApplicationContext("classpath:config/ApplicationContextProducror.xml");  

							cfg.start();
							

							SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
Date date = new Date();   
System.out.println("provider service start time��"+sdf.format(date));  

               System.in.read();  
}  
}

 

1、控制台查看

 

 

5、在dubbo-admin浏览器的提供者中会看到有一个provide

 

 

 

6、代码位置

 

 

2、消费者

 

1、pom依赖

 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.wpb.dubbo</groupId>
  <artifactId>dubbo-consumer</artifactId>
  <version>0.0.1-SNAPSHOT</version>

  <properties>
      <spring.version>4.1.3.RELEASE</spring.version>
   </properties>
   <dependencies>

																																																		<dependency>
         <groupId>com.wpb.dubbo</groupId>
         <artifactId>dubbo-provide</artifactId>
         <version>0.0.1-SNAPSHOT</version>
      </dependency>
      <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-context</artifactId>
         <version>${spring.version}</version>
      </dependency>
      <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-beans</artifactId>
         <version>${spring.version}</version>
      </dependency>
      <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-webmvc</artifactId>
         <version>${spring.version}</version>
      </dependency>
      <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-jdbc</artifactId>
         <version>${spring.version}</version>
      </dependency>
      <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-aspects</artifactId>
         <version>${spring.version}</version>
      </dependency>

 <dependency>
         <groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
         <version>2.4.10</version>
         <exclusions>
            <exclusion>
               <artifactId>spring</artifactId>
               <groupId>org.springframework</groupId>
            </exclusion>
         </exclusions>
      </dependency>

      <dependency>
         <groupId>com.101tec</groupId>
 <artifactId>zkclient</artifactId>
         <version>0.3</version>
      </dependency>
   </dependencies>
</project>

 

2、只要提供者的接口（可以通过将提供者制作成依赖jar，然后pom进行引入，也可以直接复制过来提供者的接口，笔者建议使用第一种）

 

 

3、spring配置

 

1、dubbo:reference <!-- 调用远程的接口 -->

 

<?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  
        ">       

<!-- 消费者名称 -->  
<dubbo:application name="customer"/>  
<!-- 用zookeeper注册服务中心发现服务地址 -->  
<dubbo:registry protocol="zookeeoer" address="zookeeper://127.0.0.1:2181"/>  
<!-- 调用远程的接口 -->  
<dubbo:reference id="dubboProvider" interface="com.dubbo.service.DubboProvide"/>  

</beans>

 

4、加载配置文件，并main函数进行调用测试。

 

public class CustomerMain {
public static void main(String[] args) throws InterruptedException{  
ClassPathXmlApplicationContext cfig = new ClassPathXmlApplicationContext("classpath:config/ApplicationContextCustomer.xml");  

							DubboProvide test = (DubboProvide) cfig.getBean("dubboProvider");
						
							
System.out.println("consumer connect to service begin");  
test.sayHello();  
Thread.sleep(100000);  
System.out.println("consumer connect to service end");  
}  
}

 

 

5、关照消费者端的控制台，发现没有结果，那当然不会有结果了，这个类似于webservice。会在提供者端打印结果

 

 

6、观察提供者端控制台

 

 

7、观察dubbo-admin浏览器

 

 

8、代码位置
