如何使用alpakka，spring boot和Akka-stream初始化一个连续运行的流？

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

    <!-- Alpakka -->
    <dependency>
        <groupId>com.lightbend.akka</groupId>
        <artifactId>akka-stream-alpakka-file</artifactId>
        <version>2.0.2</version>
    </dependency>

    <!-- Akka Streams -->
    <dependency>
        <groupId>com.typesafe.akka</groupId>
        <artifactId>akka-stream_2.12</artifactId>
        <version>2.6.16</version>
    </dependency>
</dependencies>

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

@Component
public class MyStream {
    @Autowired
    private ActorSystem actorSystem;

    public void run() {
        Source<Integer, NotUsed> source = Source.range(1, 10);
        Sink<Integer, CompletionStage<Done>> sink = Sink.foreach(System.out::println);

        RunnableGraph<NotUsed> graph = source.to(sink);

        graph.run(actorSystem);
    }
}

@SpringBootApplication
public class MyApp {
    @Autowired
    private MyStream myStream;

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

    @PostConstruct
    public void init() {
        myStream.run();
    }
}
