　　编写一个文件上传类，配置相关路径地址。

fileserver.physical.location=D:/projects/importTemplate/
fileserver.httpPreffix=http://121.196.54.29:8017/

　　application.properties配置路径

@RequestMapping(value = "import", method = RequestMethod.POST)
    public String importFile(ModelMap modelMap, HttpServletRequest request, HttpServletResponse response, @RequestParam("ImportExcelFile") MultipartFile upFile) throws IOException {
        SysUser user = (SysUser) SecurityUtils.getSubject().getPrincipal();
        SysImportQueue importQueue = new SysImportQueue();
        importQueue.setName("导入客户资料");
        importQueue.setStatus(0); //0 处理中 1 成功 2 失败
        importQueue.setCreatedId(user.getId());
        importQueue.setCreatedOn(new Date());
        importQueue.setCreatedBy(user.getUserName());
        try {
            String pathPhysical = uploadHelper.getPhysicalPath("import", "memeber");
            String url = uploadHelper.getUrl("import", "memeber");
            String uuid = UUID.randomUUID().toString().replace("-", "");
            String fileName = upFile.getOriginalFilename();
            importQueue.setFileName(fileName);
            String suffix = fileName.substring(fileName.lastIndexOf("."), fileName.length());
            fileName = uuid + suffix.toLowerCase();
            File newFile = new File(pathPhysical + fileName);
            FileCopyUtils.copy(upFile.getBytes(), newFile);
            url=url+fileName;
            importQueue.setFileUrl(url);
            sysImportQueueService.insert(importQueue);

        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return "appmember/import";
    }

　　相关Controller方法

<form class="form-inline" action="/appMember/import" id="importForm" name="importForm"
                                  method="post" enctype="multipart/form-data">
                                <div class="form-body">
                                    <div class="form-group">
                                        <label class="control-label">选择需要上传的文件:</label>
                                        <input type="text" name="upfile" id="upfile" class="form-control"
                                               style=" 500px;">
                                        <input type="button" value="浏览..." onclick="ImportExcelFile.click()"
                                               class="btn btn-default">
                                        <input type="file" id="ImportExcelFile" name="ImportExcelFile"
                                               style="display:none" onchange="upfile.value=this.value">
                                        <input type="button" class="btn  blue-chambray" value="上传"
                                               onclick="submit()"/>
                                    </div>
                                </div>
                            </form>

　　就可以了
