SpringBoot 整合 Dubbo

主要依赖

<dependency>
	<groupId>org.apache.dubbo</groupId>
	<artifactId>dubbo-spring-boot-starter</artifactId>
	<version>3.0.5</version>
</dependency>

<dependency>
	<groupId>org.apache.curator</groupId>
	<artifactId>curator-x-discovery</artifactId>
	<version>5.2.0</version>
</dependency>

provider(服务提供者)

application.properties

dubbo.application.name=provider-test
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.protocol.name=dubbo
dubbo.protocol.port=20881
dubbo.provider.token=true

服务接口

// 消费接口需要与提供者的接口全路径相同
public interface HelloService {
    String send();
}

@DubboService(version = "2.0.0")
public class HelloServiceImpl implements HelloService {

    @Override
    public String send() {
        String uuid = UUID.randomUUID().toString();
        return "dubbo-" + uuid;
    }
}

启动类

//服务接口实现所在包
@EnableDubbo(scanBasePackages = "com.example.api")
@SpringBootApplication
public class ProviderTestApplication {

	public static void main(String[] args) {
		SpringApplication.run(ProviderTestApplication.class, args);
	}

}

consumer(服务消费者)

application.properties

dubbo.application.name=consumer-test
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.consumer.timeout=3000
# 重试次数
dubbo.consumer.retries=2
# 启动时没有提供者时不报错
dubbo.consumer.check=false
#关闭注册中心启动时检查
dubbo.registry.check=false

服务接口

// 消费接口需要与提供者的接口全路径相同
public interface HelloService {
    String send();
}

服务调用

@Service
public class RpcService {

	// 对于服务提供的version 
    @DubboReference(version = "2.0.0")
    private HelloService helloService;

    public void get(){
        String res = helloService.send();
        System.out.println(res);
    }
}

启动类

@EnableDubbo
@SpringBootApplication
public class ConsumerTestApplication {

	public static void main(String[] args) {
		ConfigurableApplicationContext context = SpringApplication.run(ConsumerTestApplication.class, args);
		context.getBean(RpcService.class).get();
	}

}
