Spring Boot：整合Dubbo

一.dubbo-boot-provider模块

maven依赖：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
 
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.junit.vintage</groupId>
                <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.apache.dubbo/dubbo-spring-boot-starter -->
    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo-spring-boot-starter</artifactId>
        <version>2.7.3</version>
    </dependency>
 
</dependencies>

　application.properties

dubbo.application.name=dubbo-boot-provider
dubbo.registry.address=192.168.10.132:2181
dubbo.registry.protocol=zookeeper
 
dubbo.protocol.name=dubbo
dubbo.protocol.port=10000

　service类：

注意这里的@Service是Dubbo的注解，不是Spring的Service注解

@Service
public class UserServiceImpl implements UserService {
 
    @Override
    public List<User> getAll() {
        User user1 = new User(1, "张三", 12, "北京");
        User user2 = new User(2, "李四", 13, "北京");
        return Arrays.asList(user1, user2);
    }
}

　启动类：

@SpringBootApplication
@EnableDubbo//开启基于注解的dubbo功能
public class DubboBootProviderApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(DubboBootProviderApplication.class, args);
    }
 
}

二.dubbo-boot-consumer模块　

maven依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.junit.vintage</groupId>
            <artifactId>junit-vintage-engine</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-spring-boot-starter</artifactId>
    <version>2.7.3</version>
</dependency>

　消费者：

调用UserService时，用@Reference表示远程调用，而不是用@Autowired

@Controller
public class UserController {
    @Reference  //远程引用userService
    UserService userService;
    @RequestMapping("/getAll")
    @ResponseBody
    public List<User> getAll(){
        return userService.getAll();
    }
}

　application.properties

dubbo.application.name=dubbo-boot-consumer
dubbo.registry.address=zookeeper://192.168.10.132:2181
 
server.port=7070

　启动类：

@SpringBootApplication
@EnableDubbo
public class DubboBootConsumerApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(DubboBootConsumerApplication.class, args);
    }
 
}
