Serve index.html implicitly with Spring Boot

I have a simple Spring Boot Starter Web application. I want to serve several static html files.

I know that I could serve static files with Spring Boot just simply putting then to /static subdirectory of my src/main/resources.

When I create file (for example) /static/docs/index.html, then I could access it via http://localhost:8080/docs/index.html.

What I want to achieve is to access this file simply with http://localgost:8080/docs where index.html is implicitly added by Spring.

Summary:

I need to serve static files in /static/{path}/index.html in resources via localhost:8080/{path} path.

I know that I could manually create mappings in controllers, but when there is many files to serve it becomes annoying.

This will work

@Configuration
public class AppConfig implements WebMvcConfigurer {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/docs").setViewName("forward:/docs/index.html");
    }
}

Or possible solution for all static subdirs (ugly version)

public void addViewControllers(ViewControllerRegistry registry) {
    File file;
    try {
        file = new ClassPathResource("static").getFile();
        String[] names = file.list();

        for(String name : names)
        {
            if (new File(file.getAbsolutePath() + "/" + name).isDirectory())
            {
                registry.addViewController("/" + name).setViewName("forward:/" + name +"/index.html");
            }
        }
    } catch (IOException e) {
        // TODO: handle error
        e.printStackTrace();
    }
}
