一、Spring中配置tiles配置
<!-- 普通视图解析器视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"></property> <property name="suffix" value=".jsp"></property> <property name="order" value="2"></property> </bean> <!-- tiles视图解析器 --> <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver" id="urlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView"></property> <property name="order" value="1"></property> </bean> <!-- 加载tiles瓦片 --> <bean class="org.springframework.web.servlet.view.tiles3.TilesConfigurer" id="tilesConfigurer"> <property name="definitions"> <list> <value>/WEB-INF/tiles.xml</value> </list> </property> </bean>
二、tiles.xml的配置
<tiles-definitions>
<!-- 定义一个模板 -->
<definition name="layout" template="/view/index.jsp">
<put-attribute name="top" value="/view/laway/top.jsp"></put-attribute>
<put-attribute name="left" value="/view/laway/left.jsp"></put-attribute>
<put-attribute name="foot" value="/view/laway/foot.jsp"></put-attribute>
</definition>
<!-- 又定义了N个视图 控制器返回视图： sale/lookstore -->
<definition name="salay/*" extends="layout">
<put-attribute name="right" value="/view/salay/{1}.jsp"></put-attribute>
</definition>
</tiles-definitions>
说明 name为返回视图的路径
三、页面分层布局（即用下图的foot.jsp、left.jsp、top.jsp合成一个完整的页面）
foot,jsp书写如下（直接写标签就可以了）
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <h1>尾部</h1>
index.jsp书写如下
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%@ taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>My JSP \'index.jsp\' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> <style type="text/css"> .div1{ float: left; width: 200px; height: 500px; border: 1px solid red; } .div2{ width: 10 00px; height: 500px; border: 1px solid red; } </style> </head> <body> <div> <tiles:insertAttribute name="top"></tiles:insertAttribute> </div> <div> <div class="div1"> <tiles:insertAttribute name="left"></tiles:insertAttribute> </div> <div class="div2"> <tiles:insertAttribute name="right"></tiles:insertAttribute> </div> </div> <div > <tiles:insertAttribute name="foot"></tiles:insertAttribute> </div> </body> </html>
四、controller的书写
package com.exam.story.controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class ExamController {
@RequestMapping("sala")
public String sala(){
return "salay/sala";
}
@RequestMapping("salaInfo")
public String salaInfo(){
return "salay/salaInfo";
}
@RequestMapping("salaStore")
public String salaStore(HttpServletRequest request){
return "salay/salaStore";
}
@RequestMapping("goIndex")
public String goIndex(){
return "salay/sala";
}
}
界面效果如下：
