idea基于maven 创建SpringMVC项目

一、在idea中file--new--project；

二、选择maven之后勾选Create from archetype然后选择maven-archetype-webapp，点击next；如图所示

三、填写GroupId和ArtifactId,可随意写，不过一般GroupId写自己项目中包结构的前两层，ArtifactId则和自己的项目名称一致最好，Version默认即可。完成之后点击next；

四、配置maven  选择settings.xml配置文件位置和本地库位置；

需要注意一下我这里添加一个属性值，如图弹窗所示，点右边的加号，name=archetypeCatalog value=internal。就是为了图创建maven项目快，具体原因可自行查询。

五、设置项目名称和存放路劲，点击finish；

六、下面我们在pom.xml文件中添加我们所需要的依赖，因项目而异，自己需要哪个jar包就添加对应依赖就好；

等待相应的jar包下载完成之后，到这里即完成了创建maven项目--后面接着搭框架

七、添加框架支持；

      首先右键点击项目名称，选择Add FrameworkSupport...

       然后再窗口中一次选择Spring和SpringMVC并勾选自动创建spring-config.xml;如图所示：

     点击ok之后我们发现在WEB-INF下面自动生成了两个配置文件；

接下来完善自己的项目结构，首先创建一个java文件夹，并点击File--Project Structure，点击Moudles，找到刚才创建的java文件夹，选择Sources文件夹变成蓝色；

其他的结构这里就不做详细介绍了，根据项目需要而定就可以了；

      下面开始配置web.xml,我把我项目中的原样copy过来，各部分带有解释就不一一详解了；

<?xml version="1.0" encoding="UTF-8"?>
<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_3_1.xsd"
         version="3.1">

    <display-name>Archetype Created Web Application</display-name>

    <!--welcome pages-->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <!--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>
        <async-supported>true</async-supported>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!--把applicationContext.xml加入到配置文件中-->
    <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>
</web-app>

   然后开始配置 dispatcher-servlet.xml 

<?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">
    <!--此文件负责整个mvc中的配置-->

    <!--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/>

    <!--静态资源映射-->
    <!--本项目把静态资源放在了webapp的statics目录下，资源映射如下-->
    <mvc:resources mapping="/css/**" location="/WEB-INF/css/"/>
    <mvc:resources mapping="/js/**" location="/WEB-INF/js/"/>
    <mvc:resources mapping="/image/**" location="/WEB-INF/image/"/>

    <!-- 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.demo"/>
</beans>

      接下来配置applicationContext.xml 

<?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"
       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">
    <context:component-scan base-package="com.demo"/>
</beans>

配置完成之后，到这里基于maven的springMVC框架项目就算搭建完成了；

下面装载tomcat并开始项目即可！
