SpringMVC文件上传之上传搭建环境

1.打开IDEA的界面如图所示，点击Create New Project。在这里插入图片描述
2.选择Maven工程和JDK的版本以及使用骨架，并点击Next。如图所示：
3.填写项目名称和保存的地址，如图所示，并点击Next。
4. 解决maven项目创建过慢的问题如图所示，输入变量名：archetypeCatalog和变量值：internal，并点击ok和Finish。如图所示：在这里插入图片描述
5.导入相应的依赖jar包的代码如下：

    </pluginManagement>
  </build>
</project>

如图所示：项目的目录结构没有下载。
在main目录下新建Java和resouces.并设置如图所示：
8.在web.xml写人如下代码：

<!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 Application</display-name>
  <!--配置前端控制器-->
  <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>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!--配置解决中文乱码的过滤器-->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

9.在resources新建springmvc.xml的代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<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">
    <!-- 开启注解扫描 -->
    <context:component-scan base-package="com.txw"/>
    <!-- 视图解析器对象 -->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--文件所在的目录-->
        <property name="prefix" value="/WEB-INF/pages/"/>
        <!--文件的后缀名-->
        <property name="suffix" value=".jsp"/>
    </bean>
    <!--前端控制器，哪些静态资源不拦截-->
    <mvc:resources location="/css/" mapping="/css/**"/>
    <mvc:resources location="/images/" mapping="/images/**"/>
    <mvc:resources location="/js/" mapping="/js/**"/>
    <!-- 开启SpringMVC框架注解的支持 -->
    <mvc:annotation-driven/>
</beans>

10.在index.jsp的代码如下：

<%--
  Created by IntelliJ IDEA.
  User: Adair
  Date: 2020/7/2 0002
  Time: 16:07
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<html>
<head>
    <title>首页</title>
</head>
<body>
    <h3>文件上传</h3>
</body>
</html>

11.创建文件上传的处理类的代码如下：

package com.txw.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
 * 文件上传的处理类
 * @author Adair
 */
@Controller
@RequestMapping(path = "/file")
@SuppressWarnings("all")         // 注解警告信息
public class FileUploadController {
    
    
    /**
     * 文件上传
     * @return
     */
    @RequestMapping(path = "/fileUpload01")
    public String fileUpload01(){
    
    
        System.out.println("文件上传");
        return "success";
    }
}

12.在WEB_INF目录新建pages目录下success.jsp的代码如下：

<%--
  Created by IntelliJ IDEA.
  User: Administrator
  Date: 2020/7/2 0002
  Time: 16:21
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>成功页面</title>
</head>
<body>
        <h3>上传文件成功！！！</h3>
</body>
</html>

13.配置Tomcat的步骤如下：在这里插入图片描述
