2.服务提供者

resource/spring目录下添加dubbo-provider.xml:

通过 Spring 配置引用远程服务

xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"

xmlns="http://www.springframework.org/schema/beans"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd

http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">

DemoServiceImpl:

import org.apache.dubbo.config.annotation.Service;

@Service

public class DemoServiceImpl implements DemoService {

public String sayHello(String name) {

return "Hello " + name;

}

}

如果上述配置文件里面使用<dubbo:service>方式，这里可以不用加@Service

<dubbo:annotation>方式，需加上@Service

Application:

@SpringBootApplication

@ImportResource(value = {"classpath:spring/dubbo-provider.xml"})

public class Application {

public static void main(String[] args) throws Exception{

SpringApplication.run(Application.class, args);

System.in.read();

}

}

3.服务消费者

resource/spring目录下添加dubbo-consumer.xml

通过 Spring 配置引用远程服务

xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"

xmlns="http://www.springframework.org/schema/beans"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd

http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">

SayService:

import org.apache.dubbo.config.annotation.Reference;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Component;

@Component

public class SayService  {

@Reference

DemoService demoService;

public String say (String name) {

return demoService.sayHello(name);

}

}

若上述配置采用<dubbo:annotation>方式，此处使用duboo提供@Reference注解

若上述配置采用<dubbo:reference>方式，此处使用@Autowired原生注解

Application:

@SpringBootApplication

@RestController

@ImportResource("classpath:spring/dubbo-consumer.xml")

public class Application {

@Autowired

SayService sayService;

@RequestMapping("/hello")

public String say(@RequestParam("name") String name) {

return sayService.say(name);

}

public static void main(String[] args) throws Exception{

SpringApplication.run(Application.class, args);

}

}

访问localhost:8081/hello?name=zhangsan, 返回 hello zhangsan, 消费成功
