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>
