PortletContextResource.java 文件源码

/**
 * Create a new PortletContextResource.
 * <p>The Portlet spec requires that resource paths start with a slash,
 * even if many containers accept paths without leading slash too.
 * Consequently, the given path will be prepended with a slash if it
 * doesn't already start with one.
 * @param portletContext the PortletContext to load from
 * @param path the path of the resource
