因为我是在idea下搭建的web项目，所以idea下不会搭建mavenweb项目的，建议先自行百度下。

0.整体项目结构
1.创建maven项目，引入开发的工具包。
pom文件需要导入和修改的
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<spring.version>5.0.2.RELEASE</spring.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
2.配置核心控制器
在web.xml配置文件中核心控制器DispatcherServlet
<web-app>
<display-name>Archetype Created Web Application</display-name>
<!-- SpringMVC的核心控制器 -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置Servlet的初始化参数，读取springmvc的配置文件，创建spring容器 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!-- 一般来说servelet在第一次请求的时候才会创建对象，
创建后会加载我们的配置文件，那么load-on-startup就是设置服务器刚启动的
时候就加载创建servelet对象
-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
3.编写springmvc.xml的配置文件
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 配置spring创建容器时要扫描的包 -->
<context:component-scan base-package="com.xulihao"></context:component-scan>
<!-- 配置视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 配置spring开启注解mvc的支持
<mvc:annotation-driven></mvc:annotation-driven>-->
</beans>
4.编写index.jsp和HelloController控制器类
4.1 index.jsp
<!--默认的index页面是没有下面这行代码代码，目的的防止页面中文乱码-->
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>入门程序！</h1>
<a href="hello">入门程序</a>
</body>
</html>
4.2 HelloController
@Controller
public class Hellocontroller {
//请求映射
@RequestMapping(path="/hello")
public String sayhello(){
System.out.println("hello springmvc!");
return "sucess";
}
}
5.在WEB-INF目录下创建pages文件夹，编写success.jsp的成功页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>入门成功！！！！</h1>
</body>
</html>
6.启动tomcat
