一、新建过程

二、构架目录结构

1.在main目录下new出两个文件夹:java、resources。并且分别设为Sources Root 和 Resource Root。

2.在webapp目录下建立三个文件夹:js,image,css

3.在WEB-INF目录下建立一个文件夹:pages(要和视图解析器配的一致)

三、配置

1.添加相应的坐标依赖

org.springframework:spring-context、spring-web、spring-webmvc
javax.servlet:servlet-api
javax.servlet.jsp:jsp-api
<dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.5</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.2</version>
        </dependency>
    </dependencies>

 2.在Resources下创建Spring的配置文件

主要有几个作用:

a命名空间:beans,context,mvc
  b.注解扫描
  c.视图解析器
  d.注解支持:
  e.<mvc:anotation-driven>会自动加载处理映射器和处理器适配器

<?xml version="1.0" encoding="UTF-8"?>
<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"
       xmlns="http://www.springframework.org/schema/beans"
       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=""/>
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    <mvc:resources mapping="/js/**" location="/js/"/>
    <mvc:annotation-driven/>
</beans>

3.在web.xml中配置前端控制器,并且配置初始化参数

<servlet>  <servlet-name>dispatcherServlet</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <init-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:springmvc.xml</param-value>  </init-param></servlet><servlet-mapping>  <servlet-name>dispatcherServlet</servlet-name>  <url-pattern>/</url-pattern></servlet-mapping>

 4.配置tomcat
