**在IDEA中快速搭建Spring MVC项目**

一、新建project，选择spring，然后next，接着自行命名，最后finish即可。

IDEA会自动的帮我们下载需要的包。最后完成创建后项目结构如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTU5OTQwMg_size_16_color_FFFFFF_t_70][]

二、修改web.xml如下，就修改了

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTU5OTQwMg_size_16_color_FFFFFF_t_70 1][] 
<url-pattern>的值为/，目的是拦截所有的请求，并交由spring mvc的后台控制器来处理。

三、编辑 dispatcher-servlet.xml

<table> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:414.8pt;"> &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans xmlns="http://www.springframework.org/schema/beans" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"&gt; &nbsp;&nbsp;&nbsp; &lt;bean id="simpleUrlHandlerMapping" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;property name="mappings"&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;props&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;!-- /hello 路径的请求交给 id 为 helloController 的控制器处理--&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;prop key="/hello"&gt;helloController&lt;/prop&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/props&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/property&gt; &nbsp;&nbsp;&nbsp; &lt;/bean&gt; &nbsp;&nbsp;&nbsp; &lt;bean id="helloController" class="controller.HelloController"&gt;&lt;/bean&gt; &lt;/beans&gt; </td> 
 </tr> 
 </tbody> 
</table>

四、编写HelloController

<table> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:414.8pt;"> package controller; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.Controller; public class helloController implements helloController1 { &nbsp;&nbsp;&nbsp; @Override &nbsp;&nbsp;&nbsp; public ModelAndView handleRequest(javax.servlet.http.HttpServletRequest httpServletRequest, javax.servlet.http.HttpServletResponse httpServletResponse) throws Exception { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ModelAndView mav = new ModelAndView("index.jsp"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mav.addObject("message", "Hello Spring MVC"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return mav; &nbsp;&nbsp;&nbsp; } } </td> 
 </tr> 
 </tbody> 
</table>

Spring mvc通过ModelAndView对象把模型和视图结合在一起，这里视图是index.jsp数据模型为message，内容是hello spring mvc

五、index.jsp

<table> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:414.8pt;"> &lt;%@ page contentType="text/html;charset=UTF-8" language="java" %&gt; &lt;html&gt; &nbsp; &lt;head&gt; &nbsp;&nbsp;&nbsp; &lt;title&gt;$Title$&lt;/title&gt; &nbsp; &lt;/head&gt; &nbsp; &lt;body&gt; &nbsp; &lt;h1&gt;${message}&lt;/h1&gt; &nbsp; &lt;/body&gt; &lt;/html&gt; </td> 
 </tr> 
 </tbody> 
</table>

六、部署tomcat

1、run-edit configurations…

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTU5OTQwMg_size_16_color_FFFFFF_t_70 3][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTU5OTQwMg_size_16_color_FFFFFF_t_70 4][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTU5OTQwMg_size_16_color_FFFFFF_t_70 5][]

\*最后点击ok然后运行就好了

七、运行

重启服务器，然后输入地址：localhost/hello
