==================
Spring MVC文件项目
==================

1 创建项目

IDEA
    新建项目
        Maven
            名称：SpringFile
            组ID：cn.tedu
            工件ID：springfile
            版本：1.0.0

2 设置打包方式

<!-- 设置打包方式为WAR -->
<packaging>war</packaging>

3 完善Web目录结构

在/src/main目录下创建webapp目录，并在该目录下创建WEB-INF目录。

在/src/main/webapp/WEB-INF目录下创建web.xml文件：

<?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">

</web-app>

4 配置Web组件

                服务器
                    应用程序服务器：Tomcat 8.5.75
                部署
                    +工件...
                        SpringFile:war exploded
                        应用程序上下文：/SpringFile

6 添加依赖

/pom.xml：

...

<properties>
    ...
    <spring.version>5.3.14</spring.version>
    ...
</properties>

...

    </dependency>
</dependencies>

...

7 配置文件

/src/main/resources/spring-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>

    <mvc:resources mapping="/js/**" location="/js/" />
    <mvc:resources mapping="/css/**" location="/css/" />
    <mvc:resources mapping="/images/**" location="/images/" />
</beans>

8 配置Servlet

/src/main/webapp/WEB-INF/web.xml：

<?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">
    <servlet>
        <servlet-name>SpringFile</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringFile</servlet-name>
        <url-pattern>/</url-pattern>
