为< head>指定唯一的内容使用apache磁贴的部分 [英] Specifying unique content for <head> section using apache tiles
问题描述
我是Tiles的新手，所以这可能是一个非常简单的问题。我已经使用Java / Spring 3 / JSP创建了一个不使用图块的Web应用程序，现在我意识到有了它，我的生活会变得更加轻松。
I'm brand new to Tiles so this is probably a very easy question. I've created a web application using Java / Spring 3 / JSPs without the use of tiles and now I'm realizing my life would be much easier with it.
I到目前为止，在一个方面还是有些困惑，那就是定义布局。我的问题是，在网上看到的示例中，您定义了一个layout.jsp，其中包含信息（包括标签和标签）。
I'm a bit confused on one aspect thus far, and that's defining the layouts. My problem is that in examples I've seen online you define a layout.jsp which contains the information (including tags and tags).
我的问题是，布局 .jsp文件应该是通用的一个大小适合所有的文件类型，但是当我创建另一个应该使用布局模板的文件（例如welcome.jsp）时会发生什么，但是我需要定义更多和标签...如果我在welcome.jsp文件中定义它们，则呈现的JSP文件格式不正确...即：
My question is, the "layout.jsp" file is supposed to be the generic "one-size-fits-all" type of file, but what happens when I create another file (say welcome.jsp) which should USE the layout template, but I need to define more and tags... if I define them inside of the welcome.jsp file then the rendered JSP file is not formatted correctly... i.e:
<head>
<!-- This is content from the layout.jsp file -->
<title>Welcome</title>
<link rel="shortcut icon" href="images/favicon.ico"/>
<script type="text/javascript">
// some javascript
</script>
</head>
<body>
<!-- This is content from the welcome.jsp file which is malformed -->
<head>
<script src="js/jquery.mousewheel.min.js"></script>
</head>
</body>
任何帮助将不胜感激。
这是我的tile.xml：
Here's my tiles.xml:
<?xml version="1.0" encoding="UTF-8" ?>

推荐答案
创建新定义以更改标题内容：
Create a new definition to change the header content:
<definition name="baseLayout" template="/WEB-INF/jsp/layout/layout.jsp">
<!-- Defined here -->
<put-attribute name="head" value="" />
<put-attribute name="title" value="" />
...
</definition>
<definition name="videos" extends="baseLayout">
<!-- Overridden here -->
<put-attribute name="head" value="/WEB-INF/jsp/videos-additionalHeadDefinitions.jsp" />
...
</definition>
并将其添加到您的layout.jsp中：
And add this to you layout.jsp:
<head>
<!-- This is content from the layout.jsp file -->
<title>Welcome</title>
...
<tiles:insertAttribute name="head" />
</head>
