dubbo集成springboot

1.项目依赖

<dependencies>

    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo</artifactId>
        <version>${dubbo.version}</version>
    </dependency>

    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo-dependencies-zookeeper</artifactId>
        <version>${dubbo.version}</version>
        <exclusions>
            <exclusion>
                <artifactId>slf4j-log4j12</artifactId>

    </dependency>

    <!-- Spring Boot dependencies -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

</dependencies>

<dependencyManagement>
    <dependencies>
        <!-- Spring Boot -->

            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

 

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
