如何在 Liferay 中為自定義角色的布局添加 VIEW 權限

Question

我一直在嘗試為自定義角色傳播布局的查看權限，在該布局和該自定義角色的資源權限表中不存在任何條目。 如以下代碼所示，理想情況下應使用布局權限設置

ResourcePermissionServiceUtil.setIndividualResourcePermissions(groupId, companyId, layout.getModelClassName(),
                "primkey", roleIdsToActionIds);

但是，這里第一次調用有效，但第二次調用設置當前布局的父布局權限，它給出了錯誤日志中顯示的錯誤。 有人可以指導我如何實現這一目標嗎？

    // Propagete VIEW access to Page, on which Portlet is added - START
long plid = LayoutLocalServiceUtil.getDefaultPlid(groupId, false, portletId);
if(plid!=0){
Layout layout = LayoutLocalServiceUtil.getLayout(plid); 
if(layout!=null){
    _log.info("Adding permission for layout: "+layout+", layout model class name:"+layout.getModelClassName()+", scope:"+ResourceConstants.SCOPE_INDIVIDUAL
            +", primkey:"+String.valueOf(plid)+", roleid:"+customRoleId+", actionid:"+ ActionKeys.VIEW);

    Map<Long, String[]> roleIdsToActionIds = new HashMap<Long, String[]>();
    List<String> actionIds = new ArrayList<String>();
    actionIds.add(ActionKeys.VIEW);

    roleIdsToActionIds.put(customRoleId, actionIds.toArray(new String[actionIds.size()]));

    ResourcePermissionServiceUtil.setIndividualResourcePermissions(groupId, companyId, layout.getModelClassName(),
            String.valueOf(plid), roleIdsToActionIds);


    // TODO: give view permission to all its parent layouts as well
    while(layout.getParentLayoutId()!=0){
        layout = LayoutLocalServiceUtil.getParentLayout(layout);
        _log.info("Adding permission for parent layout: "+layout+", layout model class name:"+layout.getModelClassName()+", scope:"+ResourceConstants.SCOPE_INDIVIDUAL
                +", primkey:"+String.valueOf(layout.getPlid())+", roleid:"+customRoleId+", actionid:"+ ActionKeys.VIEW);

        ResourcePermissionServiceUtil.setIndividualResourcePermissions(groupId, companyId, layout.getModelClassName(),
                String.valueOf(layout.getPlid()), roleIdsToActionIds);
    }

    _log.debug("Added view permission for page of portlet:"+portletId);

    }   
} // Propagete VIEW access to Page, on which Portlet is added - END

Answer 1

所以最后看起來這個 API 調用解決了我的問題。

ResourcePermissionLocalServiceUtil.setResourcePermissions(
                                                companyId, Layout.class.getName(),
                                                ResourceConstants.SCOPE_INDIVIDUAL,
                                                String.valueOf(layout.getPlid()), customRoleId,
                                                new String[] {
                                                    ActionKeys.VIEW
                                                });

在嘗試這個之前，我還嘗試了以下兩個其他 Liferay API，但沒有成功。

ResourcePermissionLocalServiceUtil.setResourcePermissions(companyId, layout.getModelClassName(), ResourceConstants.SCOPE_INDIVIDUAL, String.valueOf(layout.getPlid()), roleIdsToActionIds);

和

ResourcePermissionServiceUtil.addResourcePermission(groupId, companyId, layout.getModelClassName(), ResourceConstants.SCOPE_INDIVIDUAL, String.valueOf(layout.getPlid()), customRoleId, ActionKeys.VIEW);

兩者都失敗了。
