创建一个普通的Maven项目,目录结构如下

 

添加依赖在pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<!--suppress ALL -->
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>org.example</groupId><artifactId>Demo</artifactId><version>1.0-SNAPSHOT</version><packaging>war</packaging><dependencies><!--        mvc的依赖--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.1.6.RELEASE</version></dependency><!--        使用request和session传值的依赖--><dependency>

<!--            jsp编译环境--><groupId>javax.servlet</groupId><artifactId>jsp-api</artifactId><version>2.0</version><scope>provided</scope></dependency><!--        json的依赖--><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.8</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-core</artifactId><version>2.7.4</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-annotations</artifactId><version>2.7.4</version></dependency></dependencies></project>

在main目录下创建webapp/WEB-INF目录，如下

 

点击file->Project Structure,选中Module,如下

点击+号，选中web添加

点击右侧的+号

 

 

修改路径如下，并保存

看我们现在的目录结构，会自动生成web.xml

在web.xml中添加如下内容

<?xml version="1.0" encoding="UTF-8"?>
<!--suppress ALL -->
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><servlet><servlet-name>mvcshine</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>mvcshine</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>

在resources创建mvc.xml,添加如下内容

<?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:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- Provide support for component scanning --><!--    指定注解的扫描目录  包名--><context:component-scan base-package="com.sun" /><!--Provide support for conversion, formatting and validation --><!--    注解驱动 --><mvc:annotation-driven/><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/"></property><property name="suffix" value=".jsp"></property></bean><!--    额外增加一个handler且他的requestmapping是  /**可以匹配到所有的请求，但是他的优先级最低只能会最后匹配，这样便可以匹配静态资源<mvc:default-servlet-handler/>
--><!--    另一种方式是可以匹配到所有的html的请求到page里取页面--><mvc:resources mapping="/html/**" location="/page/"/>
</beans>

在java目录下创建包com.sun.HelloController,目录如下

 

 

在HelloController中写入以下内容

package com.sun;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;@Controller
@RequestMapping("/hello")
public class HelloController {@RequestMapping("/hello")public String test(){return "index.jsp";}
}

 

在WEB-INF下创建一个index.jsp文件，目录结构如下

 

 

接下来配置tomcat服务器，你必须要装有服务器。

 

点击 Add Configuration

 

左上角点击+号选择Tomcat Server ->local 

 

点击顶部的Deployment->右侧的+号->选择第一个artifact

 

服务器配置成功，启动服务器

 

运行成功
