Java 如何在TileRequestProcessor中更改布局定义运行时

我有一个设想， 当请求来自IE浏览器时，显示

login

（这是默认行为），当请求来自Chrome浏览器时，显示

login\u Chrome

（布局定义在Tiles.xml中，如下所示）

注意：我不想把逻辑放在JSP中，根据条件选择包含的JSP

---

请帮助我并告诉我要覆盖

tileRequestProcessor

的哪种方法来动态更改tile定义？

在做了大量尝试和错误后，我知道我必须覆盖

tileRequestProcessor

的

processForwardConfig

方法。在那里，我必须将

path

对象的

ForwardConfig

值覆盖到我的新布局，即

login\u chrome

请参阅以下代码：

public class CustomizedTileProcessor extends TilesRequestProcessor
    {
     @Override
 protected void processForwardConfig(HttpServletRequest pRequest, 
       HttpServletResponse pResponse, ForwardConfig pForward) 
       throws IOException, ServletException
   {
      if(isChromeBrowser(pRequest))
      {
         ForwardConfig newForward = new ForwardConfig(pForward.getName(),
         pForward.getPath()+"_chrome", pForward.getRedirect(),
         pForward.getContextRelative());

         super.processForwardConfig(pRequest, pResponse, newForward);
      }
      else
      {
         super.processForwardConfig(pRequest, pResponse, pForward);
      }
   }
}

    public class CustomizedTileProcessor extends TilesRequestProcessor
    {
     @Override
   protected boolean processTilesDefinition(String pDefinitionName, boolean pContextRelative, HttpServletRequest pRequest, HttpServletResponse pResponse) throws IOException, ServletException
   {
      if (isChromeBrowser(pRequest))
      {
         pDefinitionName+="_chrome";
      }
      return super.processTilesDefinition(pDefinitionName, true, pRequest, pResponse);
   } 
}

public class CustomizedTileProcessor extends TilesRequestProcessor
    {
     @Override
 protected void processForwardConfig(HttpServletRequest pRequest, 
       HttpServletResponse pResponse, ForwardConfig pForward) 
       throws IOException, ServletException
   {
      if(isChromeBrowser(pRequest))
      {
         ForwardConfig newForward = new ForwardConfig(pForward.getName(),
         pForward.getPath()+"_chrome", pForward.getRedirect(),
         pForward.getContextRelative());

         super.processForwardConfig(pRequest, pResponse, newForward);
      }
      else
      {
         super.processForwardConfig(pRequest, pResponse, pForward);
      }
   }
}
