【Dubbo&&Zookeeper】4、 Java實現Dubbo服務提供者及消費者注冊

轉自：http://blog.csdn.net/u010317829/article/details/52128852

1. 創建Mavn工程。HelloDubbo。
2. pom.xml添加dubbo及spring架包。

 <dependency> <groupId>javaee</groupId> <artifactId>javaee-api</artifactId> <version>5</version> <scope>provided</scope> </dependency><dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1.3-b06</version> <scope>provided</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.101tec</groupId> <artifactId>zkclient</artifactId> <version>0.5</version> <exclusions> <exclusion> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> </exclusion> </exclusions> </dependency> <!-- zookeeper --> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.6</version> </dependency> <!-- spring 依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.2.14.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>3.2.14.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.2.14.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>3.2.14.RELEASE</version> </dependency> <!-- aop --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.6</version> </dependency> <dependency> <groupId>aopalliance</groupId> <artifactId>aopalliance</artifactId> <version>1.0</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.6</version> </dependency>

1. resources 目下下創建applicationContext.xml及dubbo.xml及log4j.properties 
   
    
   

2. 編寫Java代碼。實現2個數相加。 
    
   

3. 編寫Java代碼，讀取spring配置文件。 
    
   

4. dubbo-admin下查看dubbo服務是否注冊成功。 
   
5. 創建Maven工程HelloDubbo_ref。實現消費者注冊
6. 按第二步驟添加pom.xml下的依賴的架包。

7. 將HelloDubbo下的接口類及resources下的文件復制過來使用。 
    
   修改dubbo.xml及applicationContext.xml如下圖所示 
    
   

8. 編寫測試類 
   public class DubboTest { 
   public static void main(String[] args) throws IOException { 
   ApplicationContext ctx = new ClassPathXmlApplicationContext( 
   “applicationContext.xml”); 
   IFirstDubboService firstService = (IFirstDubboService) ctx 
   .getBean(“dubboFirstService”); 
   int sum = firstService.add(1, 3); 
   System.out.println(“1+3等：” + sum); 
   int count = firstService.multi(10, 1); 
   System.out.println(“10成1等：”+count); 
   //System.in.read(); 
   }

} 
取消//System.in.read(); 的注釋。運行時就可以 在dubbo管控台看見dubbo的消費者了。
