• SpringMVC文件上传


    一、创建文件上传FileController类

    package com.byzore.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.multipart.MultipartFile;
    
    import javax.servlet.http.HttpSession;
    import java.io.File;
    import java.io.IOException;
    
    @Controller
    @RequestMapping("/file")
    public class FileController {
        @RequestMapping("/fileUpload")
        /**
         * MultipartFile 选择文件
         */
        public String fileupload(HttpSession session, MultipartFile file,String author)throws IOException{
            System.out.println("作者:"+author);
            System.out.println(file);
            /**
             * 如何处理文件
             */
            if (!file.isEmpty()){
                //获取文件名称
                String fileName=file.getOriginalFilename();
                //获取到需要上传的路径
                String realPath = session.getServletContext().getRealPath("/WEB-INF/upload");
                //创建文件对象
                File uploadfile=new File(realPath+"\"+fileName);
                //如何上传文件
                file.transferTo(uploadfile);
            }
            return "index";
        }
    
    
    
        @RequestMapping("/fileUploads")
        /**
         * 多文件上传
         */
        public String fileuploads(HttpSession session, MultipartFile[] uploadFiles,String author)throws IOException{
            System.out.println("作者:"+author);
            System.out.println(uploadFiles);
            for (MultipartFile file: uploadFiles) {
                /**
                 * 如何处理文件
                 */
                if (!file.isEmpty()){
                    //获取文件名称
                    String fileName=file.getOriginalFilename();
                    //获取到需要上传的路径
                    String realPath = session.getServletContext().getRealPath("/WEB-INF/upload");
                    //创建文件对象
                    File uploadfile=new File(realPath+"\"+fileName);
                    //如何上传文件
                    file.transferTo(uploadfile);
                }
            }
    
            return "index";
        }
    }

    二、编辑applicationContext.xml文件

    <?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:aop="http://www.springframework.org/schema/aop"
               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/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
            <!--将Controller注入到容器当中   id就是浏览器请求地址-->
            <!--<bean id="/firstController" class="com.springmvc.controller.FirstController"></bean>-->
    
            <!--配置包扫描器-->
            <context:component-scan base-package="com.byzore"/>
            <!--Spring支持SpringMVC-->
            <mvc:annotation-driven/>
    
        <!--配置视图解析器-->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/"/>
            <property name="suffix" value=".jsp"/>
        </bean>
    
        <!--利用DefaultServlet放行资源-->
        <mvc:default-servlet-handler/>
    
        <!--从Spring3.0.4版本提供资源放行的方式-->
        <!--<mvc:resources mapping="/**" location="/img"/>-->
    <!--文件上传解析器-->
        <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
            <!--编码-->
            <property name="defaultEncoding" value="UTF-8"/>
            <property name="maxUploadSize" value="5000000000"/>
        </bean>
    </beans>

    三、创建fileUpload.jsp页面

    <%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>文件上传</title>
    </head>
    <body>
        <form action="/file/fileUpload" method="post" enctype="multipart/form-data">
            <input type="file" name="fileUpload"/>
    作者:<input type="text" name="author"/>
            <input type="submit" value="提交"/>
        </form>
    </body>
    </html>
