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
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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">
<dubbo:application metadata-type="remote" name="demo-springboot-provider"/>
<dubbo:metadata-report address="zookeeper://127.0.0.1:2181"/>
<dubbo:registry address="zookeeper://127.0.0.1:2181"/>
<dubbo:protocol name="dubbo"/>
<!-- dubbo注解扫描 -->
<dubbo:annotation package="cn.wjs"/>
<!-- 生成远程服务代理，可以和本地bean一样使用demoService -->
<!-- <dubbo:service interface="cn.wjs.DemoService" ref="demoService"/>-->
</beans>
|
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
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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">
<dubbo:application name="dubbo-springboot-xml-consumerr"/>
<dubbo:registry address="zookeeper://127.0.0.1:2181"/>
<!-- 使用注解方式创建远程服务代理-->
<dubbo:annotation package="cn.wjs"/>
<!-- <dubbo:reference id="demoService" check="false" interface="cn.wjs.DemoService"/>-->
</beans>
|
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
