1. fileupload 라는 spring mvc 프로젝트 생성
[전체구조]
[pom.xml]

2. 모델 작성
fileupload.jsp에서 넘기는 폼 데이터를 @ModelAttribute로 받기 위한 객체
[FileForm.java]
package onj.spring.fileupload.model;
import java.util.List;
import org.springframework.web.multipart.MultipartFile;
public class FileForm {
private List<MultipartFile> files;
private String upDir;
public List<MultipartFile> getFiles() {
return files;
}
public String getUpDir() {
return upDir;
}
public void setUpDir(String upDir) {
this.upDir = upDir;
}
public void setFiles(List<MultipartFile> files) {
this.files = files;
}
}
3. 컨트롤러 작성
[OnjController.java]
package onj.spring.fileupload.controller;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
import onj.spring.fileupload.model.FileForm;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.multipart.MultipartFile;
@Controller
public class OnjController {
@RequestMapping(value = "/view", method = RequestMethod.GET)
public String displayForm() {
return "fileupload";
}
@RequestMapping(value = "/save", method = RequestMethod.POST)
public String save(@ModelAttribute("uploadForm") FileForm uploadForm,
Model map) throws Exception {
List<MultipartFile> files = uploadForm.getFiles();
// success.jsp 로 보낼 파일 이름 저장
List<String> fileNames = new ArrayList<String>();
if (null != files && files.size() > 0) {
for (MultipartFile multipartFile : files) {
String fileName = multipartFile.getOriginalFilename();
String path = uploadForm.getUpDir() + fileName;
File f = new File(path);
multipartFile.transferTo(f);
fileNames.add(fileName);
}
}
map.addAttribute("files", fileNames);
return "success";
}
}
4. /src/main/webapp/jsp/fileupload.jsp
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<html>
<head>
<title>OnJ, OracleJavaCommunity</title>
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script>
<!-- jquery로 파일 첨부 추가 -->
$(document).ready(function() {
//add more file components if Add is clicked
$('#addFile').click(function() {
var fileIndex = $('#fileview tr').children().length;
$('#fileview').append(
'<tr><td>'+
' <input type="file" name="files['+ fileIndex +']" />'+
'</td></tr>');
});
});
</script>
</head>
<body>
<h3>Spring WEB MVC MuliFile Upload(oraclejava community)</h3>
<form:form method="post" action="save.html"
modelAttribute="uploadForm" enctype="multipart/form-data">
Upload Directory : <input type="text" name="upDir" value="c:/java/project/upload/"/><br><br>
<input id="addFile" type="button" value="File Add" />

</table>
<br/><input type="submit" value="Upload" />

<body>

<ol>
<!-- 아래 files는 컨트롤러에서 직접 넘겨준 모델명 -->

<li>${file}</li>
</c:forEach>
<!-- 컨트롤러에서 @ModelAttribute로 선언된 객체는 자동으로 view로 전달 -->
<br><br>Uload Path : ${uploadForm.upDir}

8. 실행(context명/view.html)
실행하면 파일은 c:\java\project\upload 폴더에 생성된다.
