注：参考消保维权系统，登记页面上传功能
1、JSP页面：
<%@page import="com.wondersgroup.esf.base.util.ApplicationContextUtil"%>
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ include file="../../../common/taglib.jsp" %>
<script type="text/javascript">
//替换所有
String.prototype.replaceAll = function(s1, s2) {
return this.replace(new RegExp(s1, "gm"), s2);
};
//截取上传附件路径后的名称
function getFileName(id){
var $file = $(id);
var value=$file.val();
var index=value.lastIndexOf("\\")+1;
var fileName=value.substring(index);
type=".gif|.jpeg|.jpg|.png|.bmp|.txt|.doc|.docx|.xls|.xlsx|.zip|.rar|";
if (checkAttachment(fileName, type)) {
$file.prev().val(fileName);
} else {
$file.after($file.clone().val(""));
$file.remove();
}
}
function checkAttachment(obj, AllowExt) {
var FileExt = obj.substr(obj.lastIndexOf(".")).toLowerCase();
if (AllowExt != 0 && AllowExt.indexOf(FileExt + "|") == -1) { // 判断文件类型是否允许上传
ErrMsg = "\n该文件类型不允许上传!请上传\n" + AllowExt + "类型的文件,\n当前文件类型为" + FileExt;
alert(ErrMsg);
return false;
}
return true;
}
//新增附件上传
function funAddUpload() {
var caseForm = document.getElementsByTagName("form");
if (caseForm[0].id=="formCaseInfo") {
alert("只能上传一个附件！");
} else {
var inquireRow = tbodyUpload.insertRow(tbodyUpload.rows.length);
var investorCell = inquireRow.insertCell();
var maxIndex = parseInt(tbodyUpload.getAttribute(‘maxIndex‘));
var innerHTML = $("#templateUpUp").html();
innerHTML = innerHTML.replaceAll("\\[0\\]", "[" + maxIndex + "]");
innerHTML = innerHTML.replaceAll("_0", "_" + maxIndex);
investorCell.innerHTML = innerHTML;
inquireRow.setAttribute(‘index‘, maxIndex);
tbodyUpload.setAttribute(‘maxIndex‘, maxIndex + 1);
$(‘#fileName_‘ + maxIndex).val("");
$(‘#myFiles_‘ + maxIndex).val("");
}
}
//删除咨询信息
function deleteUpload(obj) {
if (tbodyUpload.rows.length > 1) {
rowObj = getRowObj();
if (rowObj.rowIndex == 1) {
alert(‘第一行不能删除!‘);
return;

if (i < 1) {

2、保存后，后台处理代码：（参考cnAppServiceImple）
// 保存附件信息
MultipartHttpServletRequest mRequest = (MultipartHttpServletRequest) form.getRequest();
List<MultipartFile> myFiles = mRequest.getFiles("myFiles");
for (MultipartFile multipartFile : myFiles) {
if (StringUtils.isNotBlank(multipartFile.getOriginalFilename())) {
CnUpload cnUpload = new CnUpload();
cnUpload.setSerialNo(null);
cnUpload.setCaseId(caseId);
cnUpload.setFileName(multipartFile.getOriginalFilename());
cnUpload.setActId(BusinessConstants.FLOW_ID_CN_START);
cnUpload.setUploadDate(new Date());
cnUpload.setFilePath(path);
this.baseDao.persist(cnUpload);
FileUtils.copyInputStreamToFile(multipartFile.getInputStream(), new File(path, multipartFile.getOriginalFilename()));
}
}
