Spring MVC 环境搭建与配置
首先下载 Spring，我们使用的是 4.1.16 版本：
http://repo.spring.io/libs-release-local/org/springframework/spring/4.1.6.RELEASE/
然后还要下载日志包：
http://commons.apache.org/proper/commons-logging/download_logging.cgi
使用 Eclipse JavaEE 版本即可，相关依赖包已整理分享。
项目创建与依赖引入
打开 Eclipse，创建一个 Dynamic Web Project 项目，引入以下 jar 包：
commons-logging-1.2.jarspring-aop-4.1.6.RELEASE.jarspring-beans-4.1.6.RELEASE.jarspring-context-4.1.6.RELEASE.jarspring-core-4.1.6.RELEASE.jarspring-expression-4.1.6.RELEASE.jarspring-web-4.1.6.RELEASE.jarspring-webmvc-4.1.6.RELEASE.jar
并将这些包添加到 Deployment 中。
web.xml 配置
修改 web.xml 文件，主要配置分发 Servlet，该 Servlet 会读取一个 XML 文档进行更细粒度的分发。
<?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_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>SpringDemo</display-name>
<!-- configure the setting of springmvc DispatcherServlet and configure the mapping -->
<servlet>
<servlet-name>spm</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:servlet.xml</param-value>
</init-param>
<!-- <load-on-startup>1</load-on-startup> -->
</servlet>
<servlet-mapping>
<servlet-name>spm</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>Code language: HTML, XML (xml)servlet.xml 配置
在 src 目录下添加 servlet.xml，内容如下。该文件配置视图查询路径和控制器包路径。
<?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-4.1.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
<!-- scan the package and the sub package -->
<context:component-scan base-package="cn.bamn.spring"/>
<!-- don't handle the static resource -->
<mvc:default-servlet-handler />
<!-- if you use annotation you must configure following setting -->
<mvc:annotation-driven />
<!-- configure the InternalResourceViewResolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>Code language: HTML, XML (xml)控制器与视图
添加控制器和 Action：
package cn.bamn.spring;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/home")
public class HomeController {
@RequestMapping("/index")
public String hello(){
return "index";
}
}Code language: CSS (css)return 后面的字符串即为视图的 JSP 文件名。
在 WEB-INF/jsp/ 目录下创建 index.jsp：
<%@ 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">
<title>Insert title here</title>
</head>
<body>
你好吗
</body>
</html>Code language: HTML, XML (xml)访问地址：http://localhost:8080/SpringDemo/home/index
