Question

如何删除或隐藏Wicket 1.5中引入的URL中的版本号？

安装页面无济于事。

http://localhost/MyPage/SubPage?0

Answer 1

在Application.init（）中：

mount(new MountedMapperWithoutPageComponentInfo("/subpage", MyPage.class));

使用以下Mapper类：

public class MountedMapperWithoutPageComponentInfo extends MountedMapper {

  public MountedMapperWithoutPageComponentInfo(String mountPath, Class<? extends IRequestablePage> pageClass) {
    super(mountPath, pageClass, new PageParametersEncoder());
  }

  @Override
  protected void encodePageComponentInfo(Url url, PageComponentInfo info) {
    // do nothing so that component info does not get rendered in url
  }

  @Override 
  public Url mapHandler(IRequestHandler requestHandler) 
  { 
      if (requestHandler instanceof ListenerInterfaceRequestHandler ||
                requestHandler instanceof BookmarkableListenerInterfaceRequestHandler) { 
          return null; 
      } else { 
           return super.mapHandler(requestHandler); 
      } 
  } 
}

如果您不想要版本号，那么您的页面应该是完全无状态的，版本号适用于有状态页面。例如，如果您的页面包含表单，那么您应该使用Form组件的无状态变体，即org.apache.wicket.markup.html.form.StatelessForm。如果您的页面已经完全无状态，您可以通过调用org.apache.wicket.Page #setStatelessHint方法为wicket提供提示。

Answer 3

使用自创的MountedMapperWithoutPageComponentInfo类的解决方案对Wicket 6.13+不起作用，页面不会响应回调用户操作。（请注意，Internet上有多个版本的MountedMapperWithoutPageComponentInfo。）

6.13+（用6.15测试）的解决方案可以在这里找到：

http://apache-wicket.1842946.n4.nabble.com/Delete-version-number-in-url-td4665752.html

https://svn.apache.org/repos/asf/openmeetings/trunk/singlewebapp/openmeetings-web/src/main/java/org/apache/openmeetings/web/app/Application.java

// Put this code in your WebApplication subclass
import org.apache.wicket.core.request.mapper.MountedMapper;
import org.apache.wicket.request.component.IRequestablePage;
import org.apache.wicket.request.mapper.parameter.PageParametersEncoder;
import org.apache.wicket.request.mapper.info.PageComponentInfo;
import org.apache.wicket.request.IRequestHandler;
import org.apache.wicket.core.request.handler.BookmarkableListenerInterfaceRequestHandler;

private static class NoVersionMapper extends MountedMapper {
    public NoVersionMapper(final Class<? extends IRequestablePage> pageClass) {
        this("/", pageClass);
    }

    public NoVersionMapper(String mountPath, final Class<? extends IRequestablePage> pageClass) {
        super(mountPath, pageClass, new PageParametersEncoder());
    }

    @Override
    protected void encodePageComponentInfo(Url url, PageComponentInfo info) {
        //Does nothing
    }

    @Override
    public Url mapHandler(IRequestHandler requestHandler) {
        if (requestHandler instanceof ListenerInterfaceRequestHandler || requestHandler instanceof BookmarkableListenerInterfaceRequestHandler) {
            return null;
        } else {
            return super.mapHandler(requestHandler);
        }
    }
}

然后您可以使用以下方式挂载页面：

// Put this in the init() method of your WebApplication subclass
getRootRequestMapperAsCompound().add(new NoVersionMapper("urlPatternOfAPage", YourPage.class));

Answer 4

使用以下映射器来挂载页面，这应该适用于除主页之外的任何可识别书签的页面。

以下是如何在Application.init（）

中使用mapper

mount(new MountedMapperWithoutPageComponentInfo("/subpage", MyPage.class));

这是映射器。

import org.apache.wicket.request.Url;
import org.apache.wicket.request.component.IRequestablePage;
import org.apache.wicket.request.mapper.MountedMapper;
import org.apache.wicket.request.mapper.info.PageComponentInfo;
import org.apache.wicket.request.mapper.parameter.PageParametersEncoder;

public class MountedMapperWithoutPageComponentInfo extends MountedMapper {

  public MountedMapperWithoutPageComponentInfo(String mountPath, Class<? extends IRequestablePage> pageClass) {
    super(mountPath, pageClass, new PageParametersEncoder());
  }

  @Override
  protected void encodePageComponentInfo(Url url, PageComponentInfo info) {
    // does nothing so that component info does not get rendered in url
  }
}

Answer 5

对我来说，使用setStatelessHint的解决方案不起作用。以下工作：

class MyApplication extends WebApplication {
    @Override protected void init() {
        getRequestCycleSettings().setRenderStrategy(
            IRequestCycleSettings.RenderStrategy.ONE_PASS_RENDER); 
        ....
    }
}

Answer 6

对于Wicket 8，这个NoVersionMapper类可以工作：

https://github.com/apache/openmeetings/blob/master/openmeetings-web/src/main/java/org/apache/openmeetings/web/app/Application.java#L314



    public class NoVersionMapper extends MountedMapper {
        public NoVersionMapper(final Class pageClass) {
            this("/", pageClass);
        }

        public NoVersionMapper(String mountPath, final Class pageClass) {
            super(mountPath, pageClass, new PageParametersEncoder());
        }

        @Override
        protected void encodePageComponentInfo(Url url, PageComponentInfo info) {
            //Does nothing
        }

        @Override
        public Url mapHandler(IRequestHandler requestHandler) {
            if (requestHandler instanceof ListenerRequestHandler || requestHandler instanceof BookmarkableListenerRequestHandler) {
                return null;
            } else {
                return super.mapHandler(requestHandler);
            }
        }
    }

这与Devabc的代码基本相同，但是这个代码在Wicket 8上进行了编译。它已经针对以前版本的代码的已知回归进行了测试：Ajax工作，不应该触发页面刷新。

Answer 7

到目前为止建议的解决方法可能适用于特定版本并具有副作用。他们应该被视为黑客。我已经使用过这些黑客攻击而且它们被新版本打破了。因此，我在这里创建了一个通用框架支持请求（请评论/投票）：setVersioned(false) should force single Page Version。

副作用的另一个例子：Page Reload on Submit of non-versioned Page

删除网址中的版本号
