1、创建一个maven项目
https://www.jianshu.com/p/006318477719
2、在pom.xml中添加要用的依赖
<!-- spring 核心jar -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
<!-- spring web -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
<!-- spring mvc -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
3、在 web.xml 文件中部署DispatcherServlet
创建 Spring MVC 配置文件并配置 Controller 映射信息
<!-- Spring MVC servlet -->
<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:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>/</url-pattern>
</servlet-mapping>
4、在resources下创建spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
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.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 使用扫描机制扫描控制器类，控制器类都在controller包及其子包下 -->
<context:component-scan base-package="com.controller" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
5、在java在创建包com.controller
创建一个UserController类
package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* “@Controller”表示 UserController 的实例是一个控制器
*
* @Controller相当于@Controller(@Controller) 或@Controller(value="@Controller")
*/
@Controller
public class UserController {
@RequestMapping(value ="/index/login")
public String login() {
/**
* login代表逻辑视图名称，需要根据Spring MVC配置
* 文件中internalResourceViewResolver的前缀和后缀找到对应的物理视图
*/
return "login";
}
@RequestMapping(value ="/index/register")
public String register() {
return "register";
}
}
6、编写jsp文件
index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<body>
<h2>Hello World!</h2>
未注册的用户，请<a href="${pageContext.request.contextPath }/index/register"> 注册</a>！
<br/>
已注册的用户，去<a href="${pageContext.request.contextPath }/index/login"> 登录</a>！
</body>
</html>
在WEB-INF下创建login.jsp和register.jsp文件
login.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
denglu
</body>
</html>
register.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
注册
</body>
</html>
7、配置tomcat，运行程序
首先访问http://localhost:8085/index.jsp
或者直接http://localhost:8085/index/login会跳转到login页面
