先寫一個表單：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>文件上傳</title> </head> <body> <h2>文件上傳</h2> <form action="/fileUpload.jspx" enctype="multipart/form-data" method="post"> <table> <tr> <td>文件描述:</td> <td><input type="text"name="description"></td> </tr> <tr> <td>請選擇文件:</td> <td><input type="file" name="uploadFile"></td> </tr> <tr> <td><input type="submit" value="上傳"></td> </tr> </table> </form> </body> </html>
action層接收文件處理：
/** * 資源文件上傳，返回一個文件服務器地址 * @author Libin * @date 2018年1月12日 上午10:28:08 */ @RequestMapping(value ="/fileUpload.jspx") public void uploadFileBackAddress(HttpServletRequest request, HttpServletResponse response) { try { MultipartFile multipartFile = null; if (request instanceof MultipartHttpServletRequest) { multipartFile = ((MultipartHttpServletRequest)request).getFile("uploadFile"); } if (null != multipartFile) { /** * 項目服務器地址路徑 */ String projectServerPath = request.getScheme() + "://"+request.getServerName()+":" + request.getServerPort() + request.getContextPath() + "/upload/"; /** * 上傳文件絕對路徑 */ String path = request.getSession().getServletContext().getRealPath("/WEB-INF/upload/"); /** * 上傳文件名 */ String fileName = makeFileName(multipartFile.getOriginalFilename()); File file = new File(path + fileName); /** * 判斷路徑是否存在，如果不存在就創建一個 */ if (!file.getParentFile().exists()) { file.getParentFile().mkdirs(); } /** * 創建文件 */ multipartFile.transferTo(new File(path + File.separator + fileName)); /** * 返回服務器文件地址 */ String serverFilePatn = projectServerPath + fileName; } } catch (Exception e) { ajaxBackData = this.getAjaxBackDataExceptionStatus(e); } }
springMVC配置文件：
<?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:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd" default-lazy-init="true"> <context:annotation-config /> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="utf-8"></property> <property name="maxUploadSize" value="10485760000"></property> <property name="maxInMemorySize" value="40960"></property> </bean> <mvc:annotation-driven></mvc:annotation-driven> <!-- 在web.xml配置detectAllViewResolvers為false不根據ViewResolver接口全掃描，只根據viewResolver標識查找DispatcherServlet的視圖解析器 --> <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <!-- 設置前綴，即視圖所在的路徑 --> <property name="prefix" value="/WEB-INF/jsp/" /> <!-- 設置後綴，即視圖的擴展名 --> <property name="suffix" value=".jsp" /> </bean> </beans>
