idea搭建springmvc项目

1、新建maven工程并添加webapp

2、修改一些参数

3、配置maven信息

4、等待自动下载模板

5、添加java代码和一些配置文件存放的文件夹

会提示java/resouce文件夹（按住shift将两个都选上然后回车）自动创建

6、pom.xml添加依赖

<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>4.0.0modelVersion>

7、在web->WEB-INT下的web.xml中添加前端控制器（其他的随意）

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 Applicationdisplay-name>

  
  <filter>
    <filter-name>hiddenHttpMethodFilterfilter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilterfilter-class>
  filter>

  
  <filter>
    <filter-name>encFilterfilter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
    <init-param>
      <param-name>encodingparam-name>
      <param-value>utf-8param-value>
    init-param>
  filter>
  
  <filter-mapping>
    <filter-name>hiddenHttpMethodFilterfilter-name>
    
    
    <url-pattern>/*url-pattern>
  filter-mapping>

  <filter-mapping>
    <filter-name>encFilterfilter-name>
    <url-pattern>/*url-pattern>
  filter-mapping>

  
  <servlet>
    <servlet-name>dispatcherServletservlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
    <init-param>
      <param-name>contextConfigLocationparam-name>
      <param-value>classpath:springmvc.xmlparam-value>
    init-param>
    <load-on-startup>1load-on-startup>
  servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServletservlet-name>
    <url-pattern>/url-pattern>
  servlet-mapping>
web-app>

将鼠标悬停在红色提示处，然后点击创建，选择在resource文件夹下

8、在springmvc.xml文件中添加配置信息

<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">
    
    
    <context:component-scan base-package="com.mhy"/>

    
    <mvc:annotation-driven/>
    
    
    <mvc:default-servlet-handler />

    
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        
        <property name="prefix" value="/" />
        
        <property name="suffix" value=".jsp" />
    bean>
    
	
	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
	  
	  <property name="maxUploadSize" value="104857600"/>
	  
	  <property name="defaultEncoding" value="utf-8"/>
	bean>

beans>

9、配置tomcat

10、测试

浏览器访问http://localhost:8080/mvcdemo/hello，控制台显示hhh就表示搭建成功
