001--最简单Dubbo项目

话题一：搭建Dubbo项目

• 1.Dubbo依赖zookeeper进行服务注册与发现：先搭建zookeeper并运行
• 2.创建Maven项目，添加pom的dubbo依赖

• 3.创建服务提供者
  • 3.1 创建服务接口

public interface DemoService {  
    String sayHello(String name);  
} 

• 3.2 实现服务接口

public class DemoServiceImpl implements DemoService {  
      public String sayHello(String name) {  
        System.out.println("init : " + name);  
        return "hello " + name;  
    }  
}

• 3.3 添加配置文件：applicationProvider.xml

• 3.4 发布服务

public class ServerMain {  
  
    @SuppressWarnings("resource")
    public static void main(String[] args) throws Exception {  
        
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationProvider.xml");  
        context.start();  
        System.out.println("Dubbo provider start...");

        try {
            System.in.read();   // 按任意键退出
        } catch (IOException e) {
            e.printStackTrace();
        }   
    }  
}

• 3.5 自此服务已经发布，等待服务消费者调用

• 4.创建服务消费者
  • 4.1 新的项目，内容接口和接口和上面是一样的，不再需要服务实现类

public interface DemoService {  
     String sayHello(String name);  
}  

• 4.2 添加配置文件：applicationProvider.xml

• 5.创建服务消费者(服务消费)

public class ServerMain {  
  
    @SuppressWarnings("resource")
    public static void main(String[] args) throws Exception {  
        
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationProvider.xml");  
        context.start();  
        System.out.println("Dubbo Consumer start...");

        DemoService demoService = (DemoService) context.getBean("demoService");
        String hello = demoService.sayHello("world");
        System.out.println("------------------------"+hello);
        
        try {
            System.in.read();   // 按任意键退出
        } catch (IOException e) {
            e.printStackTrace();
        }   
    }  
}
