Spring MVC＆Maven＆Webjars找不到一些js文件

Question

我正在使用Intellij Idea，并制作了一个有效的Spring MVC项目。 我使用maven和webjars导入引导程序和jquery（使用webjars-locator简化了过程）。效果很好。

问题来自这样一个事实，当我添加react或babel作为依赖项时，无论我给HTML页面的路径如何，都找不到js。

<link rel='stylesheet' href='/webjars/bootstrap/css/bootstrap.min.css'> this works
<script src='/webjars/bootstrap/js/bootstrap.bundle.min.js'></script> this doesnt
<script src='/webjars/jquery/jquery.min.js'></script> this works
<script src="/webjars/react/cjs/react.development.js"></script> this doesnt
<script src="/webjars/react/react.js"></script> this doesnt
<script src="/webjars/babel/babel.js"></script> this doesnt
<script src="/webjars/babel/index.js"></script> this doesnt

maven软件包已正确下载，这是我的pom.xml

这些是软件包：

我还尝试创建一个WebConfig并指定webjars映射：

@EnableWebMvc
@Configuration
public class WebConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

        if (!registry.hasMappingForPattern("/webjars/**")) {
            registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        }
        registry.setOrder(1);
    }
}
