multiple实现文件批量上传

jsp页面：

<form id="form" enctype="multipart/form-data">
                            <table class="layout-table formBox-table" id="selectTable">
                                <tr>
                                    <th style="width:70px; text-align:right">起始日期</th>
                                    <td style="width:100px;">
                                        <input name="begin_date" id="begin_date" class="" value=""/>
                                    </td>
                                    <th style="width:70px; text-align:right">截止日期</th>
                                    <td style="width:100px;">
                                        <input name="end_date" id="end_date" value=""/>
                                    </td>
                                    <th style="width:70px; text-align:right">文件名</th>
                                    <td style="width:100px;">
                                        <input name="file_name" id="file_name" value=""/>
                                    </td>
                                    <td>
                                        <input type="file" name="upload"  id="file" value="" multiple="multiple"/>
                                        <input type="button" class="blueBtn" id="search" style="width:79px" value="查询"/>
                                        <input type="button" class="blueBtn" id="importView" style="width:79px" value="导入"/>
                                    </td>
                                </tr>
                            </table>
                        </form>

 

js：

//导入
    $("#importView").click(function(){
        var path=$("body").find("input[name='upload']").val();
        var files=document.getElementById("file").files;

        if(files.length>0){
            var isDoc=true;
            for(var i=0;i<files.length;i++){
                var name=files[i].name;
                if(name.substr(name.indexOf("."))!=".doc"){
                    isDoc=false;
                }
            }
            if(isDoc){
                var form=document.forms[0];
                form.action=basePath+"dataDownload/importWord.spring";
                form.method="post";
                form.submit();
            }else{
                $.ligerDialog.warn("请选择.doc文件");
                return;
            }
            
            
        }else{
            $.ligerDialog.warn("请选择你需要导入的文件");
            return;
        }
    })

 

　java后台：

// 导入
    @ResponseBody
    @RequestMapping(value = "/dataDownload/importWord", produces = "text/html;charset=UTF-8")
    public ModelAndView importWord(@RequestParam List<MultipartFile> upload, HttpServletRequest request)
            throws Exception {
//        filePath = new String(filePath.getBytes("iso-8859-1"), "utf-8");
        HttpSession session = request.getSession();
        Admin admin = (Admin) session.getAttribute("admin");
        String name = admin.getUserName();
        List<String> errorList=new ArrayList<>();
        for (MultipartFile mul : upload) {
                // 文件先上传到服务器中
                String filePath = request.getSession().getServletContext().getRealPath("/modelplace");
                File file = new File(filePath);
                if (!file.exists()) {
                    file.mkdir();
                }
                String filename = mul.getOriginalFilename().substring(0, mul.getOriginalFilename().indexOf("."));
                File file1 = new File(filePath, filename + ".doc");
                if (!file1.exists()) {
                    file1.createNewFile();
                }
 mul.transferTo(file1);//此处已完成单个文件的上传操作，循环完成即可上传批量文件
               29         }31         ModelAndView mv = new ModelAndView("dataDownload/lpgImport");
        return mv;
    }
