Spring mvc3 tiles

1.創建項目

eclipse裏選擇新建Maven Project,然後選擇mave-archetype-webappArchetype,這樣就會創建一個Eclipse WTP能識別的Web項目,能夠Run  on server

2.修改POM

                爲項目加入相關的dependency,包括Springtiles等。

2.1添加Spring的依賴

            <dependency>

                  <groupId>org.springframework</groupId>

                  <artifactId>spring-webmvc</artifactId>

                  <version>${org.springframework.version}</version>

                  <scope>compile</scope>

            </dependency>  

                這裏只添加spring-webmvc的依賴,Maven會根據spring-webmvc包裏的pom找到他需要的其他相關jar包的依賴,包括spring-core.jarspring-bean.jar等。

2.2添加Tiles的依賴

                Apache Tiles的官方網站上的Downloadhttp://tiles.apache.org/download.html)頁面裏有如何在Maven里加Tiles的依賴。

<!--[if !supportLists]-->·         <!--[endif]--> The complete Tiles dependency with all supported technologies

                            <dependency>

                        <groupId>org.apache.tiles</groupId>

                        <artifactId>tiles-extras</artifactId>

                        <version>2.2.2</version>

      </dependency>

<!--[if !supportLists]-->·         <!--[endif]-->The basic Tiles dependency with only servlet support

                  <dependency>

                        <groupId>org.apache.tiles</groupId>

                        <artifactId>tiles-servlet</artifactId>

                        <version>2.2.2</version>

      </dependency>

<!--[if !supportLists]-->·         <!--[endif]-->Tiles JSP support

                  <dependency>

                        <groupId>org.apache.tiles</groupId>

                        <artifactId>tiles-jsp</artifactId>

                        <version>2.2.2</version>

      </dependency>

 

2.3添加jstl依賴

                                <dependency>

                  <groupId>javax.servlet</groupId>

                  <artifactId>jstl</artifactId>

                  <version>1.2</version>

                  <scope>runtime</scope>

            </dependency>

2.4添加Servlet相關的Provided依賴

            <dependency>

                  <groupId>javax.servlet</groupId>

                  <artifactId>servlet-api</artifactId>

                  <version>2.5</version>

                  <type>jar</type>

                  <scope>provided</scope>

            </dependency>

            <dependency>

                  <groupId>javax.servlet.jsp</groupId>

                  <artifactId>jsp-api</artifactId>

                  <version>2.1</version>

                  <type>jar</type>

                  <scope>provided</scope>

            </dependency>

3.修改web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

 

      <display-name>Archetype Created Web Application</display-name>

      <servlet>

            <servlet-name>tiles</servlet-name>

            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

            <load-on-startup>1</load-on-startup>

      </servlet>

 

      <servlet-mapping>

            <servlet-name>tiles</servlet-name>

            <url-pattern>/</url-pattern>

      </servlet-mapping>

</web-app>

這裏servlet-name的值是tiles,並且沒有給DispatcherServlet配置contextConfigLocation(可以通過這個值指定spring的配置文件),Spring MVC會從WEB-INF裏去找tiles-servlet.xmlspring的配置文件。

4.tiles-servlet.xml

            <put-attribute

      </definition>

 

</tiles-definitions>

                tiles的配置文件裏定義了兩個模板(template-maintemplate-detail),template-main模板的模板jsp文件是layouts/main.jsp,其內容如下:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%>

<%@ page language="java" contentType="text/html; charset=UTF-8"

      pageEncoding="UTF-8"%>

<!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">

 

<style type="text/css">

body {

      background: #555;

      width: 400px;

      border: 1px solid #fff;

      padding: 0px;

}

 

div {

      padding: 5px;

      margin: 0px;

}

 

h1,h2,p {

      padding: 0px;

      margin: 0px;

}

 

#banner-style {

      background: #3B3E37;

}

 

#title-style {

      background: #665845;

}

 

#subtitle-style {

      background: #9F8158;

}

 

#primary-style {

      background: #EBC785;

}

 

#footer-style {

      background: #733027;

}

</style>

 

<title>Insert title here</title>

</head>

<body style="background: #555;">

 

      <div id="banner-style">

            <tiles:insertAttribute name="banner-content" />

      </div>

      <div id="title-style">

            <h2>

                  <tiles:insertAttribute name="title-content" />

            </h2>

      </div>

      <div id="primary-style">

            <tiles:insertAttribute name="primary-content" />

      </div>

      <div id="footer-style">

            <tiles:insertAttribute name="footer-content" />

      </div>

</body>

</html>

這裏定義了banner-content,title-contentprimary-contentfooter-content幾個大塊內容,這些和tiles配置文件裏的template-main模板裏的元素對應。

            <put-attribute

                  name="banner-content"

                  value="/WEB-INF/views/sections/banner.jsp" />

            <put-attribute

                  name="title-content"

                  value="Pet Type" />

            <put-attribute

                  name="primary-content"

                  value="" />

            <put-attribute

                  name="footer-content"

                  value="/WEB-INF/views/sections/footer.jsp" />

從上面的代碼中可以看出main.jsp中的banner-content使用sections/banner.jsp文件(應該是使用include)。title-content在這裏就寫死了,是Pet Type,當然子模板也可以覆蓋這個屬性。Primary-content這裏沒有設置內容,需要子模板提供相應的數據。Footer-content使用sections/footer.jsp文件。

子模板pet-tiles就繼承了上面template-main模板,其內容如下:

<definition

            name="pet-tiles"

            extends="template-main">

            <put-attribute

                  name="primary-content"

                  value="/WEB-INF/views/contents/pets.jsp" />

      </definition>

可以看出,子模板中沒有指定banner-contenttitle-contentfooter-content,只是指定了primary-content,使用contents/pets.jsp文件。

6.Controller

                Controller裏沒有什麼好說的,唯一需要說明的是,在controller的方法裏返回的視圖名不是真正對應的jsp名,要對應tiles配置文件裏的名字。比如上面的pet-tiles,而不能返回pets
