我正在为社交网络编写一个wicket项目。在我的项目中，我有身份验证，所以当用户输入主页的地址时，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());
}
}
}
});
}
}
和我的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;
}
}
在这种情况下我在我的一个受保护页面中有一个googlemap，因为googlemap需要读取数据以便从xml加载构建，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> "**/
}
}
我首先使这个页面受到保护，因此用户必须能够访问此xml但是经过多次调试我发现googlemap无法登录我的系统而不是解析dataxml它的登录页面html az输入。所以我改变了CategoriesXML的扩展以扩展WebPage。 但现在我有另一个问题： 当我去社交网站的谷歌地图页面时，我无法刷新页面，因为它过期了，所以我无法将另一个建筑物添加到我的数据xml中。 我该怎么办？ 告诉我你是否需要更多的代码或信息
答案 0 :(得分：2)
在尝试关闭OP似乎已经放弃的这个问题时，我只会发布我的旧评论作为答案..：
在您的CategoriesXML中，我强烈建议不要将标记构建和添加为字符串，并将其添加到页面中。看看你是否可以在你的.xml（？）文件中使用它，因为这是Wicket做事的方式（因此可以解决你遇到的问题）
答案 1 :(得分：1)
是否会使此WebPage扩展org.apache.wicket.Page并将标记关联为xml而不是html？基本上，模仿WebPage，但为XML实现它。
