SpringMVC是类似于struts的一款强大的MVC web开发框架。使用方便，和struts有的一比。
下面记录初次使用SpringMVC框架的maven配置过程。
1 创建maven工程
创建过程中需要注意的环节
这一步选择packaging为war，这样项目的结构就默认是web结构的项目。运行的时候就可以直接用run as->run on server方式来运行项目而不用配置做更多的设置了。
2 添加spring mvc依赖配置
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.demo</groupId>
<artifactId>webstore1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>
</project>
3 配置web.xml，在工程中启用Springmvc,，
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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>web1</display-name>
<servlet>
<servlet-name>DefaultServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>DefaultServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
添加springmvc的配置文件,文件名为DefaultServlet-servlet.xml。这个文件名的命名规则是
DispatcherServlet对应的servlet-name的内容。现在配置的servlet-name为DefaultServlet。
DefaultServlet-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<mvc:annotation-driven />
<context:component-scan base-package="com.my.webstore.controller" />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
4 创建第一个controller类,包名为com.my.webstore.controller。
package com.my.webstore.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/")
public String welcome(Model model) {
model.addAttribute("greeting", "Welcome to Web Store!");
model.addAttribute("tagline", "The one and only amazing webstore");
return "index";
}
}
5 创建jsp文件,存放路径：/WEB-INF/jsp/index.jsp
index.jsp:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet"
href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css">
<title>Welcome</title>
</head>
<body>
<section>
<div class="jumbotron">
<div class="container">
<h1>${greeting}</h1>
<p>${tagline}</p>
</div>
</div>
</section>
</body>
</html>
6 运行web项目，直接用run as->run on server方式。然后在浏览器中输入http://localhost:8080/webstore1/。如果没什么错误，应该可以正常显示首页的内容了。
