在 Quarkus 中使用 ResourceLoader

Question

I'm just experimenting with Quarkus and I'm having a problem on the ResourceLoader. Specifically, when I try to use the ResourceLoader inject, the clean install by maven goes wrong

@Autowired
private ResourceLoader resourceLoader;

this is the maven output:

[error]: Build step io.quarkus.arc.deployment.ArcProcessor#validate threw an exception: javax.enterprise.inject.spi.DeploymentException:    javax.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type org.springframework.core.io.ResourceLoader and qualifiers [@Default]

Do you know how you can use the ResourceLoader in Quarkus, or if there is an equivalent way to read a file in the classpath's resources?

This is my current situation:

I have got the files in project resources folder and I would like to read them, for example in this way:

With Spring Boot I have no problem.

Thanks in advance for your time!

I solved it in the following way:

ClassLoader classLoader = getClass().getClassLoader();

    try (InputStream is = classLoader.getResourceAsStream("domains/nations.json")) {
        this.nations = mapper.readValue(is, Nations.class);
    }

I then quit the ResourceLoader ;) thank you all
