创建springMVC工程 SpringMVCFileUpload，导入springMVC相关jar以及commons-io.jar、commons-fileupload.jar；
创建springMVC默认配置文件 SpringMVCFileUpload-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<context:component-scan base-package="com.bwy" />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>
</beans>
创建文件模型 FileModel.java:
package com.bwy.fileupload;
import org.springframework.web.multipart.MultipartFile;
public class FileModel {
private MultipartFile file;
public MultipartFile getFile() {
return file;
}
public void setFile(MultipartFile file) {
this.file = file;
}
}
编写上传页面 fileUpload.jsp:
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!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=ISO-8859-1">
<title>Spring MVC 文件上传</title>
</head>
<body>
<form:form action="/SpringMVCFileUpload/upload.do" method="post" modelAttribute="fileUpload"
enctype="multipart/form-data">
请选择一个文件上传:<input type="file" name="file" />
<input type="submit" value="提交上传" />
</form:form>
</body>
</html>
上传成功页面 success.jsp：
<%@ page language="java" 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=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
${fileName},上传成功！
</body>
</html>
编写上传文件控制类：FileUploadController.java:
package com.bwy.fileupload;
import java.io.File;
import java.io.IOException;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.util.FileCopyUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
/**
* 文件上传控制类
*
* @author Administrator
*
*/
@Controller
public class FileUploadController {
@RequestMapping(value = "/uploadPage", method = RequestMethod.GET)
public ModelAndView fileUploadPage() {
return new ModelAndView("fileUpload", "command", new FileModel());
}
@RequestMapping(value = "/upload.do", method = RequestMethod.POST)
public String upload(FileModel file, ModelMap model, HttpServletRequest request) {
// 定义文件上传目录
String fileUploadPath =
request.getSession().getServletContext().getRealPath("") + File.separator + "upload"
+ File.separator;
// 生成目录
File uploadFile = new File(fileUploadPath);
if (!uploadFile.exists()) {
uploadFile.mkdir();
}
try {
// 拷贝文件,假设上传后的文件名为：xx/xx/1.jpg
FileCopyUtils.copy(file.getFile().getBytes(), new File(fileUploadPath + "1.jpg"));
} catch (IOException e) {
e.printStackTrace();
}
model.addAttribute("fileName", file.getFile().getOriginalFilename());
return "success";
}
}
启动tomcat 运行工程：
