1.创建maven工程

然后一路Next即可创建好后的项目目录如下：

2.添加相关依赖

3.在项目工程目录上右键选择 Add FrameWork Support
4.png
如果找不到下图中的Spring 选项请参考这里：https://blog.csdn.net/dainandainan1/article/details/80318780
5.png
选择完后他会自动帮你下载同时我们的工程目录下也多了几个文件：
6.png
-
在main目录webapps 同级目录下创建java 文件夹
7.png
但是此时的java文件是灰色的，选中java文件：如下图所示，就变成蓝色了
8.png
4创建自己所需要的文件夹
.

5.web.xml配置
<!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>
<!-- 将applicationContext.xml添加进来 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--配置springmvc DispatcherServlet-->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<!--配置dispatcher.xml作为mvc的配置文件-->
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.form</url-pattern>
</servlet-mapping>
</web-app>
6.dispatcher-servlet.xml的配置文件
<?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/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">
<!--启用spring的一些annotation -->
<context:annotation-config/>
<!-- 配置注解驱动 可以将request参数与绑定到controller参数上 -->
<mvc:annotation-driven/>
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀(如果最后一个还是表示文件夹,则最后的斜杠不要漏了) 使用JSP-->
<!-- 默认的视图解析器 在上边的解析错误时使用 (默认使用html)- -->
<bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/views/"/><!--设置JSP文件的目录位置-->
<property name="suffix" value=".jsp"/>
<property name="exposeContextBeansAsAttributes" value="true"/>
</bean>
<!-- 自动扫描装配 -->
<context:component-scan base-package="com.flyz.controller"/>
</beans>
这句 <context:component-scan base-package="com.flyz.controller"/> 中 base-package一定要定位到 controller 目录否则，访问不到控制器：

-
controller包 和jsp包下分别创建 IndexController.java 和 success.jsp
IndexController ：
16.png
package com.flyz.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class IndexController {
@RequestMapping("/index")
public String index() {
return "sucess";
}
}
success.jsp:

7.Tomcat部署(前提是，IDEA Tomcat已经配置好了)

8.点击OK之后发现Tomcat 上面打了红色叉

还点击它Edit -Configurations：
