Is there an equivalent for Springs Resource in Micronaut?

Question

I am migrating a tiny Spring Boot application to Micronaut 1.0.1 and I was wondering if there is an equivalent for org.springframework.core.io.Resource and their implementation such as ClasspathResource?

In Spring Boot I inject a resource into a service using its constructor.

@Service
public class MyService() {

    private final Resource resource;

    public MyService(Resource resource) { this.resource = resource; }
}

How can I do this in Micronaut?

@Singleton
public class MyService() {

    private final Resource resource;

    @Inject
    public MyService(Resource resource) { this.resource = resource; }
}

在Micronaut中，您可以使用io.micronaut.core.io.ResourceLoader变体，例如io.micronaut.core.io.scan.ClassPathResourceLoader或io.micronaut.core.io.file.FileSystemResourceLoader。获得它们的一种选择是通过io.micronaut.core.io.ResourceResolver：

ClassPathResourceLoader loader = new ResourceResolver().getLoader(ClassPathResourceLoader.class).get();
Optional<URL> resource = loader.getResource("classpath:foo/bar.txt");
