我有一个项目，我在其中使用 google Reflections 并将该项目部署在 websphere 自由配置文件上。

我的项目有以下代码，Transformer.class 位于依赖 jar 中

private void bindTransformers(SimpleRegistry initialContext) throws Exception {
    Reflections reflections = new Reflections("no.mypackage.ntrouter");
    final Set<Class<?>> transformerClasses = reflections.getTypesAnnotatedWith(Transformer.class);
    for (Class<?> aClass : transformerClasses) {
        initialContext.put(aClass.getSimpleName(), aClass.newInstance());
    }
}

但是反射不起作用，出现以下错误：

无法从 url 创建 Vfs.Dir，找不到匹配的 UrlType [wsjar:file:

看起来 Reflections 添加了对 wsjar: URL 的支持，但自 2013 年以来就没有发布过。

你需要补丁。
