@TOC
一、SpringMVC简介
- SpringMVC是一种基于Java的实现MVC设计模型的请求驱动类型的轻量级Web框架，属于SpringFrameWork的后续产品，已经融合在Spring Web Flow中。
- SpringMVC已经成为目前最主流的MVC框架之一，并且随着Spring3.0的发布，全面超越Struts2，成为最优秀的MVC框架。它通过一套注解，让一个简单的Java类成为处理请求的控制器，而无须实现任何接口。同时它还支持RESTful编程风格的请求。
二、SpringMVC开发步骤
三、SpringMVC开发快速入门
1.SpringMVC开发步骤
- 开发步骤:
- 导入SpringMVC相关坐标
- 配置SpringMVC核心控制器DispathcerServlet
- 创建Controller类和视图页面
- 使用注解配置Controller类中业务方法的映射地址
- 配置SpringMVC核心文件spring-mvc.xml
- 客户端发起请求测试
2.案例
1.导入SpringMVC相关坐标
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>5.2.10.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.2.10.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.2.10.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.3</version>
</dependency>
</dependencies>2.配置SpringMVC核心控制器DispathcerServlet
<!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>
<!-- 配置SpringMVC前端控制器-->
<display-name>Archetype Created Web Application</display-name>
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
3.创建Controller类
package com.study.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class UserController {
@RequestMapping("/quick")
public String save(){
System.out.println("UserController....");
return "success.jsp";
}
}
4.视图类

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>Success.......</h1>
</body>
</html>
5.配置核心文件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:context="http://www.springframework.org/schema/context"
xmlns:http="http://www.springframework.org/schema/c"
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 ">
<!--Controller的组件扫描-->
<context:component-scan base-package="com.study.controller"></context:component-scan>
</beans>
