dubbo学习记录（二）
本帖最后由 HK仅輝 于 2022-9-13 16:56 编辑IDEA新建一个项目，创建三个模块
注意：这里同样要先启动 zk
一、dubbo-api （单纯的maven模块）
在这个模块中创建一个接口。
public interface DemoService {
String sayHello(String name);
}
二、dubbo-provider （springboot 模块）
在启动类同级创建一个包，然后实现api接口 ，这里使用dubbo提供的@DubboService注解
import com.dubbo.DemoService;
import org.apache.dubbo.config.annotation.DubboService;
@DubboService(version = "1.0.0")
public class DemoServiceImpl implements DemoService {
@Override
public String sayHello(String name) {
return "Hi,"+name;
}
}
三、dubbo-consumer （springboot 模块）
在启动类中，加入api接口类这里同样要用dobbo提供的 @DubboReference 注解，然后调用接口方法
import com.dubbo.DemoService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.boot.ApplicationRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class DubboConsumerApplication {
@DubboReference(version = "1.0.0")
private DemoService demoService;
public static void main(String[] args) {
SpringApplication.run(DubboConsumerApplication.class,args);
}
@Bean
public ApplicationRunner runner(){
return args -> System.out.println(demoService.sayHello("dubbo"));
}
}
