今天学习了springMVC 的上传，在此贴一下代码~~

1、创建 Javaweb 项目

2、引入相应的 jar 包

3、web.xml 配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><display-name>SpringMvc</display-name><welcome-file-list><welcome-file>index.html</welcome-file></welcome-file-list><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mvc.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping></web-app>

4、sping-mvc.xml 配置

<?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:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    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"><!-- 使用注解的包，包括子集 -->    <context:component-scan base-package="com.java"/>    <!-- 视图解析器 --><bean id="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp"></property></bean><!-- 上传配置 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="defaultEncoding" value="UTF-8"/>      <property name="maxUploadSize" value="10000000"/></bean></beans>

5、创建上传类

package com.java.controller;import java.io.File;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.multipart.MultipartFile;@Controllerpublic class FileUploadController {@RequestMapping("/upload")public String uploadFile(@RequestParam("file1") MultipartFile file1,HttpServletRequest request)throws Exception{String filePath=request.getServletContext().getRealPath("/");System.out.println(filePath);file1.transferTo(new File(filePath+"upload/"+file1.getOriginalFilename()));return "redirect:success.html";}@RequestMapping("/upload2")public String uploadFiles(@RequestParam("file") MultipartFile[] files,HttpServletRequest request)throws Exception{String filePath=request.getServletContext().getRealPath("/");System.out.println(filePath);for(MultipartFile file:files){file.transferTo(new File(filePath+"upload/"+file.getOriginalFilename()));}return "redirect:success.html";}}

6、写两个 jsp 页面

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Insert title here</title></head><body><form action="upload.do" method="post" enctype="multipart/form-data"><table><tr><th colspan="2">上传文件</th></tr><tr><td>文件一</td><td><input type="file" name="file1"/></td></tr><tr><td colspan="2"><input type="submit" value="上传文件"/></td></tr></table></form><br><br><form action="upload2.do" method="post" enctype="multipart/form-data"><table><tr><th colspan="2">上传文件</th></tr><tr><td>文件一</td><td><input type="file" name="file"/></td></tr><tr><td>文件二</td><td><input type="file" name="file"/></td></tr><tr><td colspan="2"><input type="submit" value="上传文件"/></td></tr></table></form></body></html>

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Insert title here</title></head><body>上传成功！</body></html>

到此结束啦~~
