    AND SO ON... 

我有下面的代码在我的servlet-context.xml的

<beans:bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
     <beans:property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView"/> 
     <beans:property name="order" value="0"/> 
    </beans:bean> 

    <beans:bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer"> 
     <beans:property name="resourceLoaderPath" value="/WEB-INF/views/" /> 
    </beans:bean> 

    <beans:bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver"> 
     <beans:property name="cache" value="true"/> 
     <beans:property name="prefix" value=""/> 
     <beans:property name="suffix" value=".vm"/> 
     <beans:property name="order" value="2"/> 
    </beans:bean> 

    <beans:bean id="tilesConfigurer" 
    class="org.springframework.web.servlet.view.tiles2.TilesConfigurer"> 
    <beans:property name="definitions"> 
     <beans:list> 
      <beans:value>/WEB-INF/tiles.xml</beans:value> 
     </beans:list> 
    </beans:property> 
    </beans:bean> 

我的WEB-INF /视图/ layout.jsp是

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
    pageEncoding="ISO-8859-1"%> 
<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 
<title><tiles:insertAttribute name="title"/> </title> 
</head> 
<body> 
<tiles:insertAttribute name="body"/> 
</body> 
</html> 

，最后我的速度文件家.vm是：

<html> 
<body> 
<h1> 
    Hello world! 
</h1> 
##This is comment 
<P> The time on the server is ${serverTime}. </P> 
</body> 
</html> 

tiles.xml：

<tiles-definitions> 
    <definition name="base.definition" template="/WEB-INF/views/layout.jsp"> 
      <put-attribute name="title" value="" /> 
      <put-attribute name="body" value="" /> 
    </definition> 

    <definition name="home" extends="base.definition"> 
      <put-attribute name="title" value="home" /> 
      <put-attribute name="body" value="/WEB-INF/views/home.vm" /> 
    </definition> 
<tiles-definitions> 

我读到了，您可以使用多个视图解析器来指定顺序。 SO我指定了视图解析器的顺序。

我对这项技术很新颖。请帮忙。 在此先感谢。

Answer 1

尝试增加

</tiles-definitions> 

截至tiles.xml年底。

Answer 2

修改您的tiles.xml如下template="WEB-INF/views/layout.jsp"它为我解决了无限循环问题，但仍然存在一些问题。如果您修复了这个问题，请帮助我

Answer 3

错误是由于您的属性'title'设置了与定义名称相同的值导致的。瓷砖可以使用嵌套;在案例中的标题，重定向到自己导致循环。 一个简单的解决方法是将标题值更改为不是定义名称的东西。

变化

<put-attribute name="title" value="home" /> 

到

<put-attribute name="title" value="home page" /> 

-

<tiles-definitions> 
    <definition name="base.definition" template="/WEB-INF/views/layout.jsp"> 
     <put-attribute name="title" value="" /> 
     <put-attribute name="body" value="" /> 
    </definition> 
    <definition name="home" extends="base.definition"> 
     <put-attribute name="title" value="home page" /> 
     <put-attribute name="body" value="/WEB-INF/views/home.vm" /> 
    </definition> 
<tiles-definitions> 

Answer 4

我是新手在普通瓷砖和Spring和有同样的问题定义我tiles.xml文件时。

接听特此与上述公布的解决方案和我自己的经验来阐述问题，我面对：

的问题是在值的属性<definition name="welcome" .. > 。

我将'movies'作为标题和标题属性的值。但是，'movies'不应该被用作值，因为它被用作定义。

当改变“movie”为其他值（“我的电影之家”），它工作得很好。

我的错误（堆栈溢出）使代码：

<definition name="welcome" extends="baseLayout"> 
    <put-attribute name="title" value="movies" /> 
    <put-attribute name="heading" value="movies" /> 
    <put-attribute name="tagline" value="Welcome to Movie Store" /> 
    <put-attribute name="content" value="/WEB-INF/views/movies.jsp" /> 
</definition> 
<definition name="movies" extends="baseLayout"> 
    <put-attribute name="title" value="Movies list" /> 
    <put-attribute name="heading" value="Movies List" /> 
    <put-attribute name="tagline" value="Available Products" /> 
    <put-attribute name="content" value="/WEB-INF/views/movies.jsp" /> 
</definition> 

以下是解决问题的方法：

<definition name="welcome" extends="baseLayout"> 
    <put-attribute name="title" value="My Movies Home" /> 
    <put-attribute name="heading" value="My Movies Home" /> 
    <put-attribute name="tagline" value="Welcome to Movie Store" /> 
    <put-attribute name="content" value="/WEB-INF/views/movies.jsp" /> 
</definition> 
<definition name="movies" extends="baseLayout"> 
    <put-attribute name="title" value="Movies list" /> 
    <put-attribute name="heading" value="Movies List" /> 
    <put-attribute name="tagline" value="Available Products" /> 
    <put-attribute name="content" value="/WEB-INF/views/movies.jsp" /> 
</definition>
