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

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
