文件夾上傳至服務器
希望可以給你一點幫助

直接上代碼
jsp頁面

<div style="text-align:center; vertical-align:middel" id="uploadFile">
<input type="file" name="file" id="file" multiple="multiple"
webkitdirectory /> <br> <br>
<button id="upload" οnclick="f_upload()">上傳</button>
&nbsp;&nbsp;
<button id="btnBack">返回</button>
</div>

function f_upload(){
var url =’<%=rootPath%>/module/impExp/ImpExpAction.do?method=dispatchImpt&code=<%=code%>’;
var paths = document.getElementById(“file”).files;
if(paths.length==0) {
alert(“請選擇文件”);
return;
}
var formData=new FormData();
for(var i = 0;i<paths.length;i++){
var file=paths[i];
formData.append(paths[i].name,paths[i]);
}
$.ajax({
url : url,
cache : false,
data : formData,
type : ‘POST’,
processData : false,
contentType : false,
success : function(flag) {
if (flag != “0”) {
alert(“上傳成功”);
javascript: history.back(-1);
}else{
alert(“上傳失敗!!!”)
}
}
});
}
//返回
function f_back() {
javascript: history.back(-1);
}

后端代碼
public ActionForward dispatchImpt(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response) throws Exception {
/*
* 方法二 :
*/
ResourceBundle rb = ResourceBundle.getBundle(“config”);
String userDataHomeDir = rb.getString(“USER_DATA_HOME_DIR”) + rb.getString(“AFFIX_DIR”);

String oss = commonUtil.getCloudPath();

String codeNumber =commonUtil.getCodeNumber();

>
String code = request.getParameter("code")==null?"":request.getParameter("code");
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
request.setCharacterEncoding("utf-8");
MultipartHttpServletRequest multiRequest = multipartResolver.resolveMultipart(request);
//取得request中的所有文件名
Iterator<String> iter = multiRequest.getFileNames();
while(iter.hasNext()){
//取得上傳文件
MultipartFile file = multiRequest.getFile(iter.next());
if(file!=null){
//取得當前上傳文件的文件名稱
String myFileName = file.getOriginalFilename();
//如果名稱不為“”,說明該文件存在，否則說明該文件不存在
if(myFileName.trim()!=""){
//重命名上傳后的文件名
String fileName = file.getOriginalFilename();
//定義文件上傳路徑
String dirPath=userDataHomeDir+codeNumber+code;
//阿里云存放地址
String ossPath = oss+codeNumber+code+"/"+fileName.substring(0,fileName.lastIndexOf("."))+"/"+fileName;
File dir = new File(dirPath);
if(!dir.exists()){
dir.mkdirs();
}
File localFile = new File(dir,"/"+fileName);
file.transferTo(localFile);
String uploadpath =dirPath+"/"+fileName;
System.out.println("ossPath======="+ossPath);
System.out.println("localFile==="+localFile);
System.out.println("阿里云存放路徑==="+uploadpath);

}
}
}

CommonUtil.deleteDir(bd.toString());
return null;
}
