我想知道如何从视图中删除图块。我的主要观点看起来像这样
磁贴配置由4个部分组成:标题,菜单,正文和页脚。
现在我知道如果我申请新页面,我可以覆盖主视图,例如替换正文,以便我在那里显示不同的内容。
但是我希望能够点击菜单中的链接,将我带到一个只有标题和正文(没有菜单或页脚)的页面。
然后用户将完成一个向导,他们可以从一个页面转到另一个页面,然后一旦完成,它应该再次返回到主要布局。
这是我的问题:如何从视图中删除菜单和页脚?我的问题在这里停止。
由于没有太多关于磁贴的文档,我可以找到,我想我会为其他人努力获得使用Spring工具套件使用Apache Tiles和Spring MVC的工作示例的一步一步示例(我的版本是STS 3.2.0)。

在视图文件夹中创建的JSP文件,每个文件都有内容
header.jsp中
<h2>This is the header</h2>
footer.jsp中
<p>This is the footer</p>
content1.jsp
<h1>This is content page 1</h1>
<p>Blah blah content 1</p>
content2.jsp
<h1>This is content page 2</h1>
<p>Blah blah content 2</p>
引入了menu.jsp
<h2>Menu</h2>

使用
创建“tiles.xml”文件 <?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">
<!-- This file has several definitions of page layouts -->
<tiles-definitions>
<!-- The main definition with the header footer menu and body -->
<definition name="base.definition" template="/WEB-INF/views/mainTemplate.jsp">
<put-attribute name="title" value=""></put-attribute>
<put-attribute name="header" value="/WEB-INF/views/header.jsp"></put-attribute>
<put-attribute name="menu" value="/WEB-INF/views/menu.jsp"></put-attribute>
<put-attribute name="body" value=""></put-attribute>
<put-attribute name="footer" value="/WEB-INF/views/footer.jsp"></put-attribute>
</definition>
<!-- Now you can specify as many layours as you want... The name will match the names the -->
<!-- HomeController.java returns aka... as we specified it as displayPageContent1 and displayPageContent2 -->
<!-- You can override each of the base.definition entries. In this we change the page title and display a different -->
<!-- page as the body. As we didn't override the menu of footer it will display as specified in tha base.defition-->
<definition name="displayPageContent1" extends="base.definition">
<put-attribute name="title" value="Page context 1 displaying..."></put-attribute>
<put-attribute name="body" value="/WEB-INF/views/content1.jsp"></put-attribute>
</definition>
<definition name="displayPageContent2" extends="base.definition">
<put-attribute name="title" value="Employees List"></put-attribute>
<put-attribute name="body" value="/WEB-INF/views/content2.jsp"></put-attribute>
</definition>
<definition name="mainPage" extends="base.definition">
<put-attribute name="title" value="This is the home page being displayed....."></put-attribute>
<put-attribute name="body" value="/WEB-INF/views/home.jsp"></put-attribute>
</definition>
</tiles-definitions>
tiles.xml文件将“mainTemplate.jsp”定义为基本定义。创建一个具有主html布局的文件“mainTemplate.jsp”。这些文件有“tiles:insertAttribute”,它定义了可以在每个视图中覆盖的基本布局部分。

答案 0 :(得分:4)
在Tiles.xml
中删除页眉和页脚值,如下所示:
<definition name="base.definition" template="/WEB-INF/views/mainTemplate.jsp">
<put-attribute name="title" value=""></put-attribute>
<put-attribute name="header" value=""></put-attribute>
<put-attribute name="menu" value=""></put-attribute>
<put-attribute name="body" value=""></put-attribute>
<put-attribute name="footer" value=""></put-attribute>
</definition>
然后,如果你想要唯一的标题和正文:
<definition name="displayPageContent2" extends="base.definition">
<put-attribute name="title" value="Employees List"></put-attribute>
<put-attribute name="header" value="/WEB-INF/views/header.jsp" />"></put-attribute>
<put-attribute name="body" value="/WEB-INF/views/content2.jsp"></put-attribute>
</definition>
答案 1 :(得分:1)
我不知道如果这是你所期望的,但是你可以随时添加你的tile配置,一个空文件的引用(首先创建一个) - 所以菜单将消失:
您可以在菜单jsp中移动菜单td,因此布局看起来与此类似:
<tr>
<tiles:insertAttribute name="menu"></tiles:insertAttribute>
[...]
</tr>
DEFS:
<definition name="displayPageContent1" extends="base.definition">
[...]
<put-attribute name="menu" value="/WEB-INF/views/empty.jsp"></put-attribute>
</definition>
在上面给出的场景中,将不会显示带菜单的td,与页脚部分相同。
另一种方法是制作一个定义并将其嵌套到另一个定义中,这也将导致嵌套模板,然后您可以插入这样的自定义模板(来自其他项目的示例):
<definition name="menu_template" template="/WEB-INF/layouts/main_template/header.ftl">
<put-attribute name="SYSTEM_NAME_SHORT" value="SOL"/>
<put-attribute name="menu" value="/WEB-INF/views/menus/menu.ftl"/>
</definition>
<definition name="record.history" extends="main_template">
<put-attribute name="content" value="/WEB-INF/views/xxx.ftl"/>
<put-attribute name="header" >
<definition extends="menu_template">
<put-attribute name="menu" value="/WEB-INF/layouts/blank.ftl"/>
</definition>
</put-attribute>
</definition>
如上所示,您可以将其他模板作为属性注入主模板 - 在这种情况下,菜单模板将插入到名为header的属性中。
