我们如何将多个xhtml页面包含在摘要页面中.这里所有的xhtml页面都包含相同的模板.
<!DOCTYPE html>

<h:body>
<div id="header">
<ui:insert name="commonHeader">
<ui:include src="header.xhtml" />
</ui:insert>

<div id="content">

Common Body Content.
</ui:insert>

<div id="footer">

<ui:include src="footer.xhtml" />
</ui:insert>
</div>
</h:body>
</html>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="commonTemplate.xhtml">
<ui:define name="commonBodyContent">

</ui:define>
</ui:composition>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"

template="commonTemplate.xhtml">
<ui:define name="commonBodyContent">

</ui:define>
</ui:composition>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="commonTemplate.xhtml">
<ui:define name="commonBodyContent">

</ui:define>
</ui:composition>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<ui:include src="updatePersonalDetails.xhtml" />
<ui:include src="updatedAddress.xhtml" />
<ui:include src="selectPreferences.xhtml" />
</ui:composition>
无论我在所有xhtml页面中的数据是什么,都应该在摘要页面中显示完全相同.但包括这会<html>导致在页面上呈现多个文档.
我们怎么解决这个问题？
将正文内容移动到<ui:include>模板客户端中包含的另一个模板中.
例如 updatePersonalDetails.xhtml
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="commonTemplate.xhtml">
<ui:define name="commonBodyContent">
<ui:include src="updatePersonalDetails-content.xhtml" />
</ui:define>
</ui:composition>
(也为其他人重复)
所以你可以这样做summary.xhtml:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="commonTemplate.xhtml">
<ui:define name="commonBodyContent">
<ui:include src="updatePersonalDetails-content.xhtml" />
<ui:include src="updatedAddress-content.xhtml" />
<ui:include src="selectPreferences-content.xhtml" />
</ui:define>
</ui:composition>
与具体问题无关,请考虑将模板和包含放在/WEB-INF文件夹中以防止直接访问它们.另请参阅哪些XHTML文件需要放入/ WEB-INF,哪些不是？
