    AND SO ON...

我的servlet-context.xml中有以下代码

I have the following code in my servlet-context.xml

<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/views/layout.jsp是

My WEB-INF/views/layout.jsp is

<%@ 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home.vm是:

and finally my velocity file home.vm is:

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

tiles.xml:

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，您可以在指定顺序的情况下使用多视图解析器. 所以我指定了视图解析器的顺序.

I read that, you can use multiple view resolver with specifying the order. SO I specified the order of the view resolver.

我对这项技术还很陌生.请帮忙. 预先感谢.

I am pretty new to this technology. Please help. Thanks in advance.

推荐答案

尝试添加

</tiles-definitions>

tiles.xml的末尾.
