【Dubbo&&Zookeeper】4、 Java实现Dubbo服务提供者及消费者注册

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

1. resources 目下下创建applicationContext.xml及dubbo.xml及log4j.properties 
   
    
   

2. 编写Java代码。实现2个数相加。 
    
   

3. 编写Java代码，读取spring配置文件。 
    
   

4. dubbo-admin下查看dubbo服务是否注册成功。 
   
5. 创建Maven工程HelloDubbo_ref。实现消费者注册
6. 按第二步骤添加pom.xml下的依赖的架包。

7. 将HelloDubbo下的接口类及resources下的文件复制过来使用。 
    
   修改dubbo.xml及applicationContext.xml如下图所示 
    
   

8. 编写测试类 
   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(); 的注释。运行时就可以 在dubbo管控台看见dubbo的消费者了。
