最简单的spring mvc 搭建

1.我是用maven搭建的，首先创建maven项目，这里不多说了。

2.添加pom依赖，只需要添加一个就够了spring-webmvc,它会自动下载依赖到的其它jar包

    <dependency>
    	<groupId>org.springframework</groupId>
    	<artifactId>spring-webmvc</artifactId>
    	<version>4.1.6.RELEASE</version>
    </dependency>
  </dependencies>

3.写web.xml，过滤所有请求

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  
  <!-- 请求分发器 -->
  <servlet>
  	<servlet-name>springMVC</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:springmvc.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <!-- 这里配成/表示过滤所有请求 -->
  <servlet-mapping>
  	<servlet-name>springMVC</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>
  
  <!-- 欢迎页面 -->
  <welcome-file-list>
  	<welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

4.写springmvc.xml放在根目录下

<?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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
		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">
	<!-- 默认扫描的包路径 -->  
    <context:component-scan base-package="com.security.web.login.controller" />
    
    <!-- 添加注解驱动 -->
    <mvc:annotation-driven />  
    <!-- 定义跳转的文件的前后缀 -->  
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/WEB-INF/views/" />  
        <property name="suffix" value=".jsp" />  
    </bean>  
</beans>

5.LoginController

package com.security.web.login.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class LoginController {
	
	@RequestMapping("login")
	public String login(){
		System.out.println("访问login方法了");
		return "loginSuccess";
	}
}

6.在web-inf目录下创建目录views,views下创建jsp.loginSuccess.jsp

<html>
<body>
<h2>login Success!</h2>
</body>
</html>
