我只是在试验 Quarkus，但我在 ResourceLoader 上遇到了问题。具体来说，当我尝试使用 ResourceLoader 注入时，maven 的全新安装出错了

@Autowired
private ResourceLoader resourceLoader;

这是 Maven 输出：

您知道如何在 Quarkus 中使用 ResourceLoader，或者是否有等效的方法来读取类路径资源中的文件？

这是我目前的情况：

内部资源

我有项目资源文件夹中的文件，我想阅读它们，例如以这种方式：

使用 Spring Boot 我没有问题。

在此先感谢您的时间！

我通过以下方式解决了它：

ClassLoader classLoader = getClass().getClassLoader();

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

然后我退出了 ResourceLoader ;) 谢谢大家
