Adding CSS and JavaScript files to HTML files within a Spring MVC 4 application

I'm encountering issues when trying to import my CSS files using spring 4

Initially, I attempted the following in index.html:

<link  href="../../resources/css/bootstrap.min.css" rel="stylesheet">

Although Eclipse did not detect any errors, the css was not loading on the webpage when I ran the application.

After some research, I made the following change:

registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");

For index.html, I modified it as follows, and this resolved the issue:

<link  href="resources/css/bootstrap.min.css" rel="stylesheet">

However, Eclipse flagged an error which can be seen here: look at this

Here is a snippet of the code:

@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/*.html").addResourceLocations("/WEB-INF/html/");
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
        super.addResourceHandlers(registry);
    }
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController( "/" ).setViewName( "forward:/index.html" );

    }

1) What's the correct method for importing CSS and JS in spring 4?

2) Why did the initial method with ../../ fail to work?

3) How can I import without Eclipse reporting errors?

Thank you all!^^
