1.新建api接口

/**
 * API接口，provider和consumer都要去引入这个接口
 */
public interface DemoDubboService {
    public String demo(String param);
}

2.新建provider

• pom依赖

  <parent>
  	<groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>2.3.7.RELEASE</version>
  </parent>
  <dependencies>
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter</artifactId>
          <version>2.3.7.RELEASE</version>
      </dependency>
      <dependency>
          <groupId>org.apache.dubbo</groupId>
          <artifactId>dubbo-spring-boot-starter</artifactId>

      </dependency>

          <artifactId>curator-framework</artifactId>
          <version>4.2.0</version>
      </dependency>
  </dependencies>   
  

• application.yml

  dubbo:
    application:
      name: dubbo-provider
    registry:
      address: zookeeper://127.0.0.1:2181
  

• 实现接口

  import com.msb.dubbo.service.DemoDubboService;
  import org.apache.dubbo.config.annotation.Service;
  
  /**
   * 此类为接口的实现类，
   * Service注解为apache的@Service.此注解是区分项目是Provider还是Consumer最重要依据
   */
  @Service
  public class DemoDubboServiceImpl implements DemoDubboService {
      public String demo(String param) {
          System.out.println("执行demo");
          return param + "123";
      }
  }
  

• 启动类

  import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
  import org.springframework.boot.SpringApplication;
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  
  /**
   * 必须要有@EnableDubbo注解，否则Dubbo不生效。
   */
  @SpringBootApplication
  @EnableDubbo
  public class ProviderApplication {
      public static void main(String[] args) {
          SpringApplication.run(ProviderApplication.class, args);
      }
  }
  

3.新建consumer

• pom依赖

  <parent>
  	<groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>2.3.7.RELEASE</version>
  </parent>
  <dependencies>
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>

      <dependency>
          <groupId>org.apache.dubbo</groupId>
          <artifactId>dubbo-spring-boot-starter</artifactId>
          <version>2.7.3</version>
      </dependency>
      <dependency>
          <groupId>org.apache.curator</groupId>
          <artifactId>curator-recipes</artifactId>
          <version>4.2.0</version>
      </dependency>
      <dependency>
          <groupId>org.apache.curator</groupId>
          <artifactId>curator-framework</artifactId>
          <version>4.2.0</version>
      </dependency>
  </dependencies>   
  

• application.yml

  dubbo:
    application:
      name: dubbo-cunsumer
    registry:
      address: zookeeper://127.0.0.1:2181
  

• Service类

  import com.msb.dubbo.service.DemoDubboService;
  import org.apache.dubbo.config.annotation.Reference;
  import org.springframework.stereotype.Service;
  
  /**
   * 调用服务使用@Reference注解org.apache.dubbo.config.annotation.Reference;
   */
  @Service
  public class DemoService{
  
      @Reference
      private DemoDubboService demoDubboService;
  
      public String demo() {
          return demoDubboService.demo("张三丰");
      }
  }
  

• Controller类

  import com.msb.service.DemoService;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.stereotype.Controller;
  import org.springframework.web.bind.annotation.RequestMapping;
  import org.springframework.web.bind.annotation.ResponseBody;
  
  @Controller
  public class DemoController {
  
      @Autowired
      private DemoService demoService;
  
      @RequestMapping("/demo")
      @ResponseBody
      public String demo() {
          return demoService.demo();
      }
  }
  

• 启动类

  import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
  import org.springframework.boot.SpringApplication;
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  
  @SpringBootApplication
  @EnableDubbo
  public class ConsumerApplication {
      public static void main(String[] args) {
          SpringApplication.run(ConsumerApplication.class, args);
      }
  }
