在/portal-master/portal-impl/src/portal.properties文件中，有如下配置：
# # Set this to true if users are shown that they do not have access to a # portlet. The portlet init parameter "show-portlet-access-denied" will # override this setting. # layout.show.portlet.access.denied=true
修改为：
# # Set this to true if users are shown that they do not have access to a # portlet. The portlet init parameter "show-portlet-access-denied" will # override this setting. # layout.show.portlet.access.denied=false
