because of lots of static files like bootstrap css and js file and other, the war file is heavy and its taking too much time to load first page I'm not sure that heavy war file is a reason why a page is loading slow. There are tons of reasons that can cause such behavior. I'd suggest to look closer on that first.

how to separate out static files, such as bootstrap from your war?

Spring MVC can be configured to serve static assets from a file system:

Here is an example:

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry
      .addResourceHandler("/files/**")
      .addResourceLocations("file:/opt/files/");
 }

how do I resolve this problem?

I'm using public CDN servers (https://maxcdn.bootstrapcdn.com, https://cdnjs.cloudflare.com, https://cdn.rawgit.com, https://yandex.st) for the static resources like Bootstrap, jQuery, etc.
