Spring MVC笔记(七) springMVC文件上传

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：
