/**
 * Constructs and returns a special merged resource request mapper using the path and resources
 * options specified in this builder.//from   w w  w  .j a v  a 2s .  c  om
 * <p>
 * This method may only be called after all of the options have been set.
 * <p>
 * Use this method if your application has a complex configuration that requires you to deal
 * with request mappers directly (e.g. you need to wrap or combine them in clever ways).
 * Most applications will be better served by {@link #install install()}, which
 * handles creating the mapper and mounting it in one easy step.
 * 
 * @throws IllegalStateException if a path or resources have not been
 *         specified prior to calling this method.
 *
 * @since 3.0
