本文概述

• Spring MVC中Tiles支持的优势
• Spring MVC Tiles示例

Spring提供了与apache tile框架的集成支持。因此, 我们可以借助Spring Tile支持简单地管理Spring MVC应用程序的布局。
Spring MVC中Tiles支持的优势 可重用性：我们可以在多个页面中重用单个组件, 例如页眉和页脚组件。
集中控制：我们只能通过单个模板页面来控制页面的布局。
易于更改布局：借助单个模板页面, 我们可以随时更改页面的布局。因此, 你的网站可以轻松采用新技术, 例如引导程序, jQuery等。
目录结构
让我们在Eclipse中查看Spring Tile示例的文件。

Spring MVC Tiles示例 1.将依赖项添加到pom.xml文件。
pom.xml

< !-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> < dependency> < groupId> org.springframework< /groupId> < artifactId> spring-webmvc< /artifactId> < version> 5.1.1.RELEASE< /version> < /dependency> < !-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> < dependency> < groupId> javax.servlet< /groupId> < artifactId> servlet-api< /artifactId> < version> 3.0-alpha-1< /version> < /dependency> < !-- https://mvnrepository.com/artifact/javax.servlet/jstl --> < dependency> < groupId> javax.servlet< /groupId> < artifactId> jstl< /artifactId> < version> 1.2< /version> < /dependency> < !-- https://mvnrepository.com/artifact/org.apache.tomcat/tomcat-jasper --> < dependency> < groupId> org.apache.tomcat< /groupId> < artifactId> tomcat-jasper< /artifactId> < version> 9.0.12< /version> < /dependency> < !-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-jsp --> < dependency> < groupId> org.apache.tiles< /groupId> < artifactId> tiles-jsp< /artifactId> < version> 3.0.5< /version> < /dependency> < !-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-servlet --> < dependency> < groupId> org.apache.tiles< /groupId> < artifactId> tiles-servlet< /artifactId> < version> 3.0.5< /version> < /dependency> < !-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-core --> < dependency> < groupId> org.apache.tiles< /groupId> < artifactId> tiles-core< /artifactId> < version> 3.0.5< /version> < /dependency> < !-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-el --> < dependency> < groupId> org.apache.tiles< /groupId> < artifactId> tiles-el< /artifactId> < version> 3.0.5< /version> < /dependency>

2.创建bean类
Contact.java

package com.srcmini.form; public class Contact { private String firstname; private String lastname; private String email; private String telephone; public String getEmail() { return email; } public String getTelephone() { return telephone; } public void setEmail(String email) { this.email = email; } public void setTelephone(String telephone) { this.telephone = telephone; } public String getFirstname() { return firstname; } public String getLastname() { return lastname; } public void setFirstname(String firstname) { this.firstname = firstname; } public void setLastname(String lastname) { this.lastname = lastname; } }

3.创建控制器类
HelloWorldController.java

package com.srcmini.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class HelloWorldController { @RequestMapping("/hello") public String helloWorld(Model m) { String message = "Hello World, Spring MVC @ srcmini"; m.addAttribute("message", message); return "hello"; } }

ContactController.java

package com.srcmini.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.validation.BindingResult; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.SessionAttributes; import com.srcmini.form.Contact; @Controller @SessionAttributes public class ContactController { @RequestMapping(value = "http://www.srcmini.com/addContact", method = RequestMethod.POST) public String addContact(@ModelAttribute("contact") Contact contact, BindingResult result) { //write the code here to add contact return "redirect:contact.html"; } @RequestMapping("/contact") public String showContacts(Model m) { m.addAttribute("command", new Contact()); return "contact"; } }

4.在web.xml文件中提供控制器的条目
【Spring MVC Tiles用法示例详解】web.xml

< ?xml version="1.0" encoding="UTF-8"?> < web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> < display-name> SpringTiles< /display-name> < welcome-file-list> < welcome-file> index.jsp< /welcome-file> < /welcome-file-list> < servlet> < servlet-name> spring< /servlet-name> < servlet-class> org.springframework.web.servlet.DispatcherServlet < /servlet-class> < load-on-startup> 1< /load-on-startup> < /servlet> < servlet-mapping> < servlet-name> spring< /servlet-name> < url-pattern> *.html< /url-pattern> < /servlet-mapping> < /web-app>

5.在xml文件中定义bean
spring-servlet.xml

< beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> < context:annotation-config /> < context:component-scan base-package="com.srcmini.controller" /> < bean id="viewResolver" class="org.springframework.web.servlet.view.tiles3.TilesViewResolver"/> < bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer"> < property name="definitions"> < list> < value> /WEB-INF/tiles.xml< /value> < /list> < /property> < /bean> < /beans>

6.提供tile.xml文件
Tiles.xml

< ?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"> < tiles-definitions> < definition name="base.definition" template="/WEB-INF/jsp/layout.jsp"> < put-attribute name="title" value="" /> < put-attribute name="header" value="http://www.srcmini.com/WEB-INF/jsp/header.jsp" /> < put-attribute name="menu" value="http://www.srcmini.com/WEB-INF/jsp/menu.jsp" /> < put-attribute name="body" value="" /> < put-attribute name="footer" value="http://www.srcmini.com/WEB-INF/jsp/footer.jsp" /> < /definition> < definition name="contact" extends="base.definition"> < put-attribute name="title" value="http://www.srcmini.com/Contact Manager" /> < put-attribute name="body" value="http://www.srcmini.com/WEB-INF/jsp/contact.jsp" /> < /definition> < definition name="hello" extends="base.definition"> < put-attribute name="title" value="http://www.srcmini.com/Hello Spring MVC" /> < put-attribute name="body" value="http://www.srcmini.com/WEB-INF/jsp/hello.jsp" /> < /definition> < /tiles-definitions>

7.创建请求的页面
index.jsp

< a href="http://www.srcmini.com/hello.html"> Hello Spring< /a> | < a href="http://www.srcmini.com/contact.html"> Contact< /a>

8.创建其他视图组件
hello.jsp

< html> < head> < title> Spring MVC Example< /title> < /head> < body> < h1> Welcome to Spring MVC< /h1> < p> Message is: ${message}< /p> < /body> < /html>

contact.jsp

< %@taglib uri="http://www.springframework.org/tags/form" prefix="form"%> < html> < head> < title> Spring Tiles Contact Form< /title> < /head> < body> < h2> Contact Manager< /h2> < form:form method="post" action="addContact.html"> < table> < tr> < td> < form:label path="firstname"> First Name< /form:label> < /td> < td> < form:input path="firstname" /> < /td> < /tr> < tr> < td> < form:label path="lastname"> Last Name< /form:label> < /td> < td> < form:input path="lastname" /> < /td> < /tr> < tr> < td> < form:label path="lastname"> Email< /form:label> < /td> < td> < form:input path="email" /> < /td> < /tr> < tr> < td> < form:label path="lastname"> Telephone< /form:label> < /td> < td> < form:input path="telephone" /> < /td> < /tr> < tr> < td colspan="2"> < input type="submit" value="http://www.srcmini.com/Add Contact"/> < /td> < /tr> < /table> < /form:form> < /body> < /html>

header.jsp

< h2> Header< /h2> < hr/>

footer.jsp

< hr/> < p> Copyright2010-2014 srcmini.com.< /p>

menu.jsp

< p> Menu 1< /p> < p> Menu 2< /p>

layout.jsp

< %@ 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=UTF-8"> < title> < tiles:insertAttribute name="title" ignore="true" /> < /title> < /head> < body> < div> < tiles:insertAttribute name="header" /> < /div> < div style="float:left; padding:10px; width:15%; "> < tiles:insertAttribute name="menu" /> < /div> < div style="float:left; padding:10px; width:80%; border-left:1px solid pink; "> < tiles:insertAttribute name="body" /> < /div> < div style="clear:both"> < tiles:insertAttribute name="footer" /> < /div> < /body> < /html>
