If you don't use Spring MVC (for example, you are using Jersey), you can also solve this by using a javax.servlet.Filter:

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class AngularRoutingFilter implements Filter {

  @Override
  public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
    HttpServletRequest httpServletRequest = ((HttpServletRequest) request);
    String requestURI = httpServletRequest.getRequestURI();

    if (shouldDispatch(requestURI)) {
        request.getRequestDispatcher("/").forward(request, response);
    } else {
        chain.doFilter(request, response);
    }
  }

  @Override
  public void init(FilterConfig filterConfig) {}

  @Override
  public void destroy() {}

  private boolean shouldDispatch(String requestURI) {
    /* Exclude/Inlclude URLs here */
    return !(requestURI.startsWith("/api") || requestURI.equals("/"));
  }

}
