我正在为社交网络编写一个检票口项目。在我的项目中，我进行了身份验证，因此当用户输入主页地址时，他会以这种方式重定向到登录页面：

public class MyApplication extends WebApplication {

    private Folder uploadFolder = null;

    @Override
    public Class getHomePage() {
        return UserHome.class;
    }

    public Folder getUploadFolder()
    {
        return uploadFolder;
    }

    @Override
    protected void init() {
        super.init();

        // Disable the Ajax debug label!
        //getDebugSettings().setAjaxDebugModeEnabled(false);


        this.getMarkupSettings().setDefaultMarkupEncoding("UTF-8");
        this.getRequestCycleSettings().setResponseRequestEncoding("UTF-8");
        mountBookmarkablePage("/BossPage", BossPage.class);
        mountBookmarkablePage("/Branch", EditProfile.class);
        mountBookmarkablePage("/SA", SuperAdmin.class);
        mountBookmarkablePage("/Admin", ir.pnusn.branch.ui.pages.administratorPages.EditProfile.class);
        mountBookmarkablePage("/Student", StudentSignUP.class);
        mountBookmarkablePage("/Student/Test", StudentSignUpConfirm.class);
        mountBookmarkablePage("/Branch/categories.xml", CategoriesXML.class);

        get().getPageSettings().setAutomaticMultiWindowSupport(true);
        getResourceSettings().setThrowExceptionOnMissingResource(false);
        uploadFolder = new Folder("C:\\", "wicket-uploads");
        uploadFolder.mkdirs();

        this.getSecuritySettings().setAuthorizationStrategy(WiaAuthorizationStrategy.getInstance());
        this.getSecuritySettings().setUnauthorizedComponentInstantiationListener(WiaAuthorizationStrategy.getInstance());
        addComponentInstantiationListener(new IComponentInstantiationListener() {

            public void onInstantiation(final Component component) {
                if (!getSecuritySettings().getAuthorizationStrategy().isInstantiationAuthorized(component.getClass())) {
                    try {
                        getSecuritySettings().getUnauthorizedComponentInstantiationListener().onUnauthorizedInstantiation(component);
                    } catch (Exception e) {
                        System.out.println("ERRORRRRRRR:" + e.toString());
                    }
                }
            }
        });

    }
}

我的 WiaAuthorizationStrategy 类是这样的，它将通过名称 Realm.xml 从 xml 文件中获取页面名称和用户角色：

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package ir.pnusn.ui.library;

import ir.pnusn.authentication.RealmPolicy;
import ir.pnusn.authentication.ui.pages.Login;
import org.apache.wicket.Component;
import org.apache.wicket.RestartResponseAtInterceptPageException;
import org.apache.wicket.authorization.Action;
import org.apache.wicket.authorization.IAuthorizationStrategy;
import org.apache.wicket.authorization.IUnauthorizedComponentInstantiationListener;

public final class WiaAuthorizationStrategy implements
        IAuthorizationStrategy,
        IUnauthorizedComponentInstantiationListener {

    private RealmPolicy roleManager;
    private static WiaAuthorizationStrategy instance;

    private WiaAuthorizationStrategy() {
        roleManager = RealmPolicy.getInstance();
    }

    public static WiaAuthorizationStrategy getInstance() {
        if(instance == null)
            instance = new WiaAuthorizationStrategy();
        return instance;
    }

    public boolean isInstantiationAuthorized(Class componentClass) {

        if (ProtectedPage.class.isAssignableFrom(componentClass)) {
            if (WiaSession.get().getUser() == null) {
                return false;
            }
            if(!roleManager.isAuthorized(WiaSession.get().getUser().getRole(), componentClass.getName()))//WiaSession.get().isAuthenticated();
            {
                WiaSession.get().setAccess(false);
                return false;
            }
            else
                return true;
        }

        return true;
    }

    public void onUnauthorizedInstantiation(Component component) {
        throw new RestartResponseAtInterceptPageException(
                Login.class);
    }

    public boolean isActionAuthorized(Component component, Action action) {
        //System.out.println("Name:" + component.getClass().getName() + "\n Action:" + action.getName() + "\nUser:" + WiaSession.get().getUser());
        if (action.equals(Component.RENDER)) {
            if (roleManager.containClass(component.getClass().getName()))
             {
                if (WiaSession.get().getUser() != null) {
                    if(!roleManager.isAuthorized(WiaSession.get().getUser().getRole(), component.getClass().getName()))
                    {
                        WiaSession.get().setAccess(false);
                        return false;
                    }
                    return true;
                }
                return false;
            }
        }
        return true;
    }
}

在这种情况下，我的一个受保护页面中有一个 googlemap，因为 googlemap 需要读取数据以从 xml 加载建筑，所以我创建了一个 servlet，它将根据用户名动态创建它。这个 servlet 如下：

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package ir.pnusn.branch.ui.pages;

import ir.pnusn.branch.database.BranchNotFoundException;



import ir.pnusn.branch.database.DatabaseException;
import ir.pnusn.branch.facade.admin.branchDataEnter.BranchDataSubmitFacade;
import ir.pnusn.branch.facade.admin.branchDataEnter.BuildingBean;


import java.util.Iterator;
import java.util.List;
import org.apache.wicket.PageParameters;
import org.apache.wicket.RequestCycle;
import org.apache.wicket.markup.html.WebPage;

/**
 *
 * @author mohammad
 */
public class CategoriesXML extends WebPage
{

    public CategoriesXML(PageParameters parameters)
    {
        System.out.println("user " + parameters.getString("user"));
        StringBuilder builder = new StringBuilder("<markers>");
        List<BuildingBean> buildings;
        try
        {
            buildings = BranchDataSubmitFacade.createBranchDataSubmitFacade(parameters.getString("user")).getBranchSecondPageData();
            for (Iterator<BuildingBean> it = buildings.iterator(); it.hasNext();)
            {
                BuildingBean buildingBean = it.next();
                builder.append("<marker lat=\"");
                builder.append(buildingBean.getLatit());
                builder.append("\" lng=\"");
                builder.append(buildingBean.getLongit());
                builder.append("\"");
                builder.append(" address=\"");
                builder.append(buildingBean.getDesctiption());
                builder.append("\" category=\"branch\" name=\"");
                builder.append(buildingBean.getBuildingName());
                builder.append("\"/>");

            }
            builder.append("</markers>");

        }
        catch (DatabaseException ex)
        {
            builder = new StringBuilder("<markers></markers>");
        }
        catch (BranchNotFoundException ex)
        {
            builder = new StringBuilder("<markers></markers>");
        }
        RequestCycle.get().getResponse().println(builder.toString());
        /*"<markers>" +
        "<marker lat=\"35.69187\" lng=\"51.413269\" address=\"Some stuff to display in the First Info Window\"  category=\"branch\" name=\"gholi\"/>" +
        "<marker lat=\"52.91892\"  lng=\"78.89231\" address=\"Some stuff to display in the Second Info Window\" category=\"branch\" name=\"taghi\"/>" +
        "<marker lat=\"40.82589\"  lng=\"35.10040\" address=\"Some stuff to display in the Third Info Window\"  category=\"branch\" name=\"naghi\"/>" +
        "</markers> "**/
    }
}

我首先让这个页面受到保护，所以用户必须登录才能访问这个 xml，但是经过大量调试后，我发现 googlemap 无法登录我的系统，所以它不是解析 dataxml，而是解析登录页面 html az 输入. 所以我改变了 CategoriesXML 的扩展来扩展 WebPage。但是现在我遇到了另一个问题：当我转到我的社交网站中的谷歌地图页面时，我无法刷新页面，因为它已过期，所以我无法将另一个建筑物添加到我的数据 xml 中。我应该怎么办？告诉我您是否需要更多代码或信息

在试图关闭这个OP似乎已经放弃的问题时，我将发布我的旧评论作为答案..：

在您的 CategoriesXML 中，我强烈建议不要将您的标签构建和添加为字符串并将它们添加到页面中。看看您是否可以将其放入 .xml(?) 文件中，因为这是 Wicket 做事的方式（因此可能会解决您遇到的问题）

是否会使此 WebPage 扩展 org.apache.wicket.Page 并将标记关联以返回为 xml 而不是 html？基本上，模仿网页，但为 XML 实现它。
