需要org.springframework下的5个包文件：
spring-web；spring-tx；spring-context-support；spring-webmvc；spring-jdbc
以及javax.servlet下的jstl和taglibs下的standard包
<modelVersion>4.0.0</modelVersion>
<properties>
<spring.version>3.2.14.RELEASE</spring.version>
</properties>
<groupId>org.mastiff</groupId>
<artifactId>mastiff</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>${spring.version}</version>
</dependency>

<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>1.1.2</version>
</dependency>
</dependencies>
导入包以后在web.xml中配置Spring的DispatchServlet将所有请求交给spring处理
<servlet>
<servlet-name>mastiff</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:/xml/spring-web.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mastiff</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
classpath*:/xml/spring-web.xml文件内容如下：
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:task="http://www.springframework.org/schema/task"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<!-- spring mvc的注解式映射 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter" />
</beans>
此时启动项目，console日志中会出现如下信息：
警告: No mapping found for HTTP request with URI [/] in DispatcherServlet with name ‘mastiff‘
因为没有扫描Controller，没有映射关系
新建一个简单的Controller：org.mastiff.controller.LoginController
package org.mastiff.controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
/**
* @功能描述：登录控制器
* @author yang.wei
* @time 2015年9月9日 上午10:40:44
* @version 0.0.1
*/
@Controller
public class LoginController {
@RequestMapping("/")
public ModelAndView login(HttpServletRequest res) {
ModelAndView mv = new ModelAndView();
mv.setViewName("login");
return mv;
}
}
在spring-web.xml文件中增加扫描Controller的代码
<!-- 扫描controller -->
<context:component-scan base-package="org.mastiff.controller" />
注意，加在<beans>标签下第一行位置。然后重启项目，映射关系就生成了
信息: Mapped "{[/],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.web.servlet.ModelAndView org.mastiff.controller.LoginController.login(javax.servlet.http.HttpServletRequest)
至此，SpringMVC的配置完成。
