Question

我正在为WebSphere Portal 8创建一个Portlet，并且想要检索呈现我的Portlet的页面名称。这很重要，因为根据页面的不同，Portlet将以不同的方式处理内容

我尝试使用NavigationSelectionModel API，但认为我没有正确使用它。我希望这段代码在呈现视图之前发生，然后将代码放入doView方法中。问题是我无法转换ServletRequest / Response，因为doView方法中只有RenderRequest和RenderResponse。

public void doView(RenderRequest request, RenderResponse response)
            throws PortletException, IOException {
        // Declarations
        List<ForeignAuthority> faList = new ArrayList<ForeignAuthority>();
        String resp;

        // Set the MIME type for the render response
        response.setContentType(request.getResponseContentType());

        // Check if portlet session exists
        ForeignAuthoritiesPortletSessionBean sessionBean = getSessionBean(request);
        if (sessionBean == null) {
            response.getWriter().println("<b>NO PORTLET SESSION YET</b>");
            return;
        }

        try{
        Context ctx = new InitialContext();
        NavigationSelectionModelHome home = (NavigationSelectionModelHome) 
            ctx.lookup("portal:service/model/NavigationSelectionModel");
        if (home != null) {
            NavigationSelectionModelProvider provider = 
                home.getNavigationSelectionModelProvider();
            NavigationSelectionModel model = 
                provider.getNavigationSelectionModel((ServletRequest)request, (ServletResponse)response);
            for (java.util.Iterator i = model.iterator(); i.hasNext(); ) 
            {
                NavigationNode node = (NavigationNode) i.next();
                if (i.hasNext()) {
                    System.out.println(node.getObjectID().getUniqueName());
                }
            }
        }
        }catch(Exception e){
            e.printStackTrace();
        }

        PortletRequestDispatcher rd = getPortletContext()
                .getRequestDispatcher(getJspFilePath(request, VIEW_JSP));
        rd.include(request, response);
}

预期结果将是检索呈现portlet的当前页面的页面名称或唯一名称。

您可以尝试下面的代码片段是否有帮助。您可以获取URI值并从中提取页面名称。

HttpServletRequest httpServletRequest = PortletUtils.getHttpServletRequest（renderRequest）; httpServletRequest.getRequestURI（）;

如何从WebSphere Portal页面获取页面名称？
