如何使用 Apache Tiles 和 Spring MVC 自动导入主体

我有以下tiles-def.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">
<tiles-definitions>
<definition name="default" template="/WEB-INF/jsp/layout.jsp">
    <put-attribute name="title" value="my webapp" />
    <put-attribute name="header" value="/WEB-INF/jsp/header.jsp" />
    <put-attribute name="menu" value="/WEB-INF/jsp/menu.jsp" />
    <put-attribute name="body" value="/WEB-INF/jsp/hello.jsp" />
    <put-attribute name="footer" value="/WEB-INF/jsp/footer.jsp" />
</definition>

<definition name="contact" extends="default">
    <put-attribute name="body" value="/WEB-INF/jsp/contact.jsp" />
</definition>

<definition name="hello" extends="default">
    <put-attribute name="body" value="/WEB-INF/jsp/hello.jsp" />
</definition>
</tiles-definitions>

如您所见，在我的所有页面中，只有正文发生变化。有没有办法自动执行此操作？（所以它会自动包含具有所请求页面名称的jsp，或者如果不存在则包含错误页面？）

谢谢！

编辑：我想做的更多细节：

现在怎么样：对于我的 web 应用程序的每个新页面，我都必须向tiles-def.xml 添加一个新页面。每次，它唯一做的就是用我的内容页面设置正文。

我想做的事：只需有一个自动选择要显示的页面的默认定义，如下所示：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">
<tiles-definitions>
<definition name="default" template="/WEB-INF/jsp/layout.jsp">
    <put-attribute name="title" value="my webapp" />
    <put-attribute name="header" value="/WEB-INF/jsp/header.jsp" />
    <put-attribute name="menu" value="/WEB-INF/jsp/menu.jsp" />
    if(myPageName exists){
        <put-attribute name="body" value="/WEB-INF/jsp/" + myPageName + ".jsp" />
    else{
        <put-attribute name="body" value="/WEB-INF/jsp/error404.jsp" />
    }
    <put-attribute name="footer" value="/WEB-INF/jsp/footer.jsp" />
</definition>
</tiles-definitions>

其中 myPageName 是所请求页面的名称（如果 URL 为“http://www.mysite.com/contact.html”，则 myPageName如果是“http://www.mysite.com/info.html”，则 myPageName 将为“info”）。

我该怎么做？

原文

I have the following tiles-def.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">
<tiles-definitions>
<definition name="default" template="/WEB-INF/jsp/layout.jsp">
    <put-attribute name="title" value="my webapp" />
    <put-attribute name="header" value="/WEB-INF/jsp/header.jsp" />
    <put-attribute name="menu" value="/WEB-INF/jsp/menu.jsp" />
    <put-attribute name="body" value="/WEB-INF/jsp/hello.jsp" />
    <put-attribute name="footer" value="/WEB-INF/jsp/footer.jsp" />
</definition>

<definition name="contact" extends="default">
    <put-attribute name="body" value="/WEB-INF/jsp/contact.jsp" />
</definition>

<definition name="hello" extends="default">
    <put-attribute name="body" value="/WEB-INF/jsp/hello.jsp" />
</definition>
</tiles-definitions>

As you can see, in all my pages, just the body changes. Is there a way to automate this? (so it automatically includes the jsp that has the name of the requested page, or an error page if it doesnt exist?)

Thank you!

EDIT: More details of what I want to do:

How it is now:
For each new page of my webapp, I have to add a new to my tiles-def.xml. And everytime, the only thing it does is setting the body with my content page.

What I would like to do:
Just have one default definition that automatically chose the page to display, something like this:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">
<tiles-definitions>
<definition name="default" template="/WEB-INF/jsp/layout.jsp">
    <put-attribute name="title" value="my webapp" />
    <put-attribute name="header" value="/WEB-INF/jsp/header.jsp" />
    <put-attribute name="menu" value="/WEB-INF/jsp/menu.jsp" />
    if(myPageName exists){
        <put-attribute name="body" value="/WEB-INF/jsp/" + myPageName + ".jsp" />
    else{
        <put-attribute name="body" value="/WEB-INF/jsp/error404.jsp" />
    }
    <put-attribute name="footer" value="/WEB-INF/jsp/footer.jsp" />
</definition>
</tiles-definitions>

Where myPageName would be the name of the page requested (If the URL was "http://www.mysite.com/contact.html", then myPageName would be "contact". If it was "http://www.mysite.com/info.html", then myPageName would be "info").

How can I do this?
